① 为什么说宇宙可能是一个巨大生物的细胞

很明显不是。人们总是会用类比思维去想象事情，从而陷入思维惯性的错误。设想一下这个七八岁的小孩都能想象到的东西，从古至今无数的科学家会没想到吗，肯定是科学家经过研究从而排除了这个说法。
不妨仔细思考一下就能想到细胞主要是依靠分裂繁衍，宇宙是靠分裂繁衍的吗？宇宙甚至都没有一个分裂的过程。而且宇宙和细胞的运行轨迹也不一样。
这个问题就跟你发现铜是导电的，金是导电的，而且他们颜色很相似，于是你就觉得铜就等于金一样，都是类比思维带来的谬论。

② 人类灭绝并不会影响宇宙运转，人类对于宇宙而言，究竟算是什么呢

人对于宇宙空间来说是无关紧要的，如同一颗砂粒一样。地球文明发展到今天，人类自认为是伟大存有，但在宇宙空间中出现的许多宝贵的生命是人类所无法探索的，在广阔无垠的宇宙上，人类是渺小的，如同一粒沙子沙漠里中好不值一提。

因此人们对宇宙空间存有来着实际意义来讲是无关痛痒的一件事情。尽管人们通过上亿年的演变独霸了地球上，可是如果有一天人们确实灭亡了以后，地球上又会有一个新的种群来替代人们所以和针对地球上本身来说人们没那么重要针对宇宙空间而言地球上并不是那么关键那样人们对宇宙空间而言存有其实就是非常渺小人们存在宇宙空间中间的价值也就基本不会有。

③ 宇宙和大脑中神经元及其相似，那么宇宙会是个生命体吗

宇宙的诞生一直是困扰大家一个谜题，人类对宇宙的探索还要追溯到远古时期，当时人类科技有限，还无法进入宇宙中，看一眼宇宙真实模样，所以大家联想到宇宙是神仙居住的地方，进入现代社会后，生产力进步创造出很多天文望远镜和航空飞机，揭开了关于宇宙秘密，这时候大家才初步认识宇宙，不过有很多谜题等待人类揭开，对于古代人来说，现代人起码看到宇宙的模样

这一结论一出颠覆了大家的想象，毕竟在大家的认知中，宇宙只是一个普普通通的神经细胞，如果宇宙是一个相对成熟的大脑，那么在这个大脑中是否还存在和人类一样的超级文明的，它们现在又在何处呢？

④ 神经与神经元的区别与联系是什么

神经元，又称神经组织，是构成神经系统结构和功能的基本单位。神经元是具有长突起的细胞，它由细胞体和细胞突起构成
神经 ：神经纤维构成的组织,把脑和脊髓的兴奋传给各个器官,或把各个器官的兴奋传给脑和脊髓
神经元，又称神经细胞，是构成神经系统结构和功能的基本单位。
神经是神经元及介质构成的系统；神经是系统。
之所以经常用神经而省去了系统，是因为神经本身就是个系统概念。按生理心理学定义，神经是由神经元构成的系统，即神经元系统。其中神经元就是神经这个系统基

按生理心理学定义，神经是由神经元构成的系统，即神经元系统。其中神经元就是神经这个系统基本的功能结构单位。神经元定义： 高等动物神经系统的结构和功能单位。 包括细胞体、轴突和树突。 简介神经元，又称神经组织，是构成神经系统结构和功能的基本单位。神经元是具有长突起的细胞，它由细胞体和细胞突起构成。细胞体位于脑、脊髓和神经节中，细胞突起可延伸至全身各器官和组织中。细胞体是细胞含核的部分，其形状大小有很大差别，直径约4～120微米。核大而圆，位于细胞中央，染色质少，核仁明显。细胞质内有斑块状的核外染色质（旧称尼尔小体），还有许多神经元纤维。细胞突起是由细胞体延伸出来的细长部分，又可分为树突和轴突。每个神经元可以有一或多个树突，可以接受刺激并将兴奋传入细胞体。每个神经元只有一个轴突，可以把兴奋从胞体传送到另一个神经元或其他组织，如肌肉或腺体。


神经元: 神经元即神经细胞,是高度分化的细胞.具有感受刺激传导冲动和整合信息的功能,是神经系统形态结构与功能的基本单位. 2,神经元的形态结构: 神经元是由细胞体和突起两部分组成. 3,神经元的分类:(1)按神经元突起数目分类:单极神经元,双极神经元,多极神经元 (2)按神经元功能分类:感觉神经元(传入神经元),运动神经元(传出神经元),联络神经元(中间神经元). (二 ) 神经纤维:神经纤维是由运动神经的轴突或感觉神经元的长树突(两者统称为轴素)与包在它外表的神经胶质细胞构成的. 神经纤维分有髓神经纤维和无髓神经纤维. 说白了就是神经元的突起部分是组成神经纤维的一部分。神经纤维构成了神经。神经又分为运动、感觉、混合神经。在人脑的结构中。神经元的细胞体构成了灰质部分。神经纤维构成了白质部分

⑤ 宇宙这么大，人类算什么是宇宙的一个细胞，还是连细胞都不算呢

嗯，这个问题。

先不说宇宙，我们先说太阳系，1977年发射的旅行者1号截止目前已经飞了42年了，而且是以每秒钟17公里飞行的，这相当于从北京到上海只需要1分钟，就这个速度，它才刚飞出太阳系，你没有听错，仅仅一个小小的太阳系。

再继续提高尺度，银河系。

银河系有多大估计我不用说了吧，光速穿越太阳系需要8个小时，穿越银河系需要10万年。

光速有多快？一秒钟30万千米！

这是啥概念？人类永远理解不了的概念

1秒钟的时间，光可以绕地球飞7.5圈，真的是飞着玩，地球真的太小了。

飞银河系呢？10万年，你怕了没？

真的，就一个银河系就这么大，更别提其他的星系了，仙女星系，等等等等，在星系上还有星系团，星系团上...

不说了，因为人类永远无法理解宇宙有多大，永远永远...

一、若宇宙是一个生命体，那人类又算什么？

答案太奇妙了

每当我们抬头看着美的浩渺的星空，我们就会有一种天上地下唯我独尊的一种佛陀即视感，佛家所说的那种先觉者的智慧寂寞感，其实和我们在面对宇宙的那种无限的孤寂和渺小感是何其的相似。宇宙是那样的庞大，而我们人类是那样的渺小，我们或许始终难以理解宇宙和人类之间的那种隔阂差距，只知道用一种非常渺小的形容自身。但人类一直都在 探索 着这个庞大的宇宙，用尽我们的生命旅程，去揭开它的面纱。

在网上，科学家曾经提出了一个有趣的话题，假若宇宙是一个庞大的生命体，那么身处在它之中的人类到底又算什么呢？这个答案似乎充满的那种科学的戏谑感，人类在地球上或许是一个了不起的物种，但是在如此伟大的宇宙面前，我们没有任何可比性。从体积上来看，如果宇宙是一个庞大的生命，那么我们人类可能连一个细胞或者原子都配不上。那么人类在宇宙中到底又算什么呢？

其实这个问题又涉及到了科学领域的哲学思考，关于宇宙生命体的这个思考，科学家早在很早之前就已经开始了，天文学家对于宇宙的某些天体观测似乎发现了一些不同寻常的现象。当年科学家在发现宇宙长城的时候就有了这种想法，所谓的宇宙长城，是在宇宙之间延绵上千光年的宇宙星云，他们是宇宙星系形成的前兆。天体在其中缠绕在这一团巨大的连绵星云里面，它们就好像宇宙的经络一般，在黑暗的宇宙星空里面一闪一闪的发光，好似人的大脑神经元的冲动。宇宙真的好像是一个庞大的生命体，有着自身的生命结构，而我们只是在其中的一个微小部分。

但虽然人类在宇宙的结构里面，可能只是一个渺小到连分子都算不上的存在，但是人类却是独一无二的。在整个后面的无机世界里面，人类是唯一一个有着自己思考，能够创造出自己的语言文字的独特存在，我们是唯一的生命，虽然我们比不上宇宙的浩渺，但是我们能够书写自己的独特，在这个浩渺的宇宙里面留下自己的足迹。

宇宙虽然浩渺无比，虽然无比壮观，但是若没有人类这样的智慧生物为它书写为它记录，它的存在未必真的就那么有意义。对于宇宙而言我们微不足道，但是对于人类而言我们却是独一无二。而且宇宙终究只是一个稳固的发展状态，而他的未来可能性也不可预期，但是人类却有着无尽的爆发力，我们能够创造一个又一个的发展奇迹，未来未必不能够站在与他同等的地位上进行交谈。人类是渺小的人类也是伟大的，并且在宇宙中是独一无二的。

二、人类和宇宙相比，究竟有多渺小？

我用一组数字来对比一下：一个太阳能容纳130万个地球，一个银河系能容纳1000亿个太阳，一个小星系团能容纳40个银河系，一个星系团能容纳100个小星系团，一个星系能容纳10亿个星系团，超星系团能容纳几十个星系……

从这组数字可以看出，人类相对于宇宙来说，是多么多么的渺小，甚至渺小到可以忽略不计。那么，人类这么渺小，到底生存的意义是什么呢？这个问题很有意思，不过我可以明确的告诉你，人类生存的意义非常重大。佛教有言：一叶一菩提，一花一世界。也就是说，即使是一片树叶，或者一朵鲜花，都是一个宇宙，一个世界。那对我们人体来说，就更能称得上一个小宇宙了。

细想一下，我们的人体是由什么组成的？大到皮肤、骨骼和器官，小到细胞、质子和原子，甚至有数不清的细菌也弥漫在身体的角角落落。那么，我们能说人体这些最小的单位没有价值吗？事实上，也正是这些最小的单位才构成了人体。

因此，我们对于宇宙来说虽然渺小，却是宇宙最基本的构成单位，如果没有这些渺小的组织，也就不可能存在宇宙。而我们按照宇宙规律做事，也正是满足了宇宙生长的需求，所以，好好生活吧，我们离不开宇宙，而宇宙也更离不开我们！

三、宇宙是什么呢？宇宙从哪里来又要到哪里去呢？

现代 科技 技术手段让我们知道宇宙的目前可观测年龄为138.2亿年。最新的研究认为宇宙的直径可达920亿光年，甚至更大。起源于约138亿年前的一个奇点的大爆炸。而且他还在不限增大。

奇点是什么呢？奇点在什么样的地方爆炸？

138亿年前的一次一个奇点的大爆炸创造了我们今天所使用所看到的一切的一切，宇宙本就是无限可能的存在，奇点大爆炸是一个从无到有的创造过程。

我们所观测到的宇宙是一个物质存在的宇宙，时至今日我们也没能弄清楚我们在宇宙的位置与目的。研究所认为的宇宙的直径920亿光年也仅仅只是我们的可观测宇宙。要知道什么是可观测宇宙，可观测宇宙实际上指的是我们领用最先进的设备仪器所能探测到的宇宙范围。可想而知我们的可观测发内意外必定还有着无法想象的广袤的空间，这些空间或许永远也不可能被我们所观测得到，因为那里发出的光永远也不乏到达地球。

因为有了宇宙的大爆炸所以才有了我们今天所能看到的宇宙全貌，在每一个夜晚我们抬头望向深空就在那遥远的最深邃的宇宙深处无时不在上演着一个个令渺小的我们所惊奇的事件。

2009年11月，天文学家在宇宙遥远区域发现了一个巨大的由此前不被人知的星系构成的星系团，巨大星系团的发现将帮助天文学家了解潜在的宇宙网"骨架"

宇宙是由众多星系构成的庞大"宇宙网"串成丝状或卷须状。宇宙网的丝状物是由暗物质维系在一起的。宇宙网被认为是由宇宙中密布的漏斗形的星系、气体和暗物质构成，仿佛混沌的"星系际高速公路"。看上去非常的像我们体内的一条基因或者细胞。没错这就是宇宙神经网。

这就是人类迄今为止观测到的大到足以令任何一个人惊奇的宇宙网，我们所处的位置也是一样的我们所处在宇宙内部的某一个位置的移动的宇宙网中的室女座超星系群中，这个超星系群也在做着绕宇宙网的公转自转运动。

我们就在这个超星系团内的我们认为的本星系群内，本星系群(Local Group of Galaxies)是指银河系和相邻仙女星系、麦哲伦星云等30个星系组成了一个规模较小的集团。包括银河系在内的一群星系。本星系群中的全部星系覆盖一块直径大约1000万光年的区域。

在这个本身有着绕超星系团自转公转的有30多个星系。

而就在这个超星系群中的一个不起眼的角落才有着我们夜晚抬头望天所看到的银河系。我们晚上所看的到的星星都在银河系的范围内，就连直径10万光年的银河系也同样有着自己的公转自转。

最后提到的是我们的家一个人类十几万年发展史都还没有一个人离开过的家我们的太阳系。

银河系是一个棒旋星系， 直径约10万光年，包括一千亿到四千亿恒星。太阳是银河系较典型的恒星，位于分支悬臂猎户臂上，离银河系中心有2.61万光年，太阳系移动速度约240㎞/s，2.26亿年转一圈。

太阳系中的八大行星都位于差不多同一平面的近圆轨道上运行，朝同一方向绕太阳公转。除金星以外，其他行星的自转方向和公转方向相同。彗星的绕日公转方向大都相同，多数为椭圆形轨道，一般公转周期比较长。

轨道环绕太阳的天体被分为三类:行星、矮行星和太阳系小天体。

行星是环绕太阳且质量够大的天体。

我们的太阳系就是一个这样的存在对于我们来说已经很大很大。但其实对于我们的宇宙来说也仅仅只是一个沙尘微不足道。

从我们的地球到太阳系再到银河系又到本星系群又再到室女座超星系团他们都无一不在运动，这些运动看似对于宇宙的存在无关紧要，时至今日也没人能说清宇宙的目的是什么。因此这些运动又像是一个至关重要的存在。运动的本身存在的摩擦、碰撞、吞噬、竞争，无不令我们感到惊奇。

他让我们看到了我们的存在是多么的微不足道又是多么的至关重要。

近期有一些理论分支认为我们存在的宇宙看起来更像是一个巨大的生物一个我们永远也不乏了解的生物。

是的，在我们谈论宇宙的时候，往往人类是心存敬畏的，因为宇宙太大了，人类了解的只不过是皮毛，但就目前的科学研究来说，宇宙可能并不是一个生命体，大多数科学家都认为宇宙是无中生有，从一个奇点慢慢演化而来的，那么我退一万步来说，如果宇宙真的是某一种人类不了解的生命形式，那么对人类的冲击恐怕是巨大的，也是很难接受的，试想一下，人类只是这个生命体当中的一个细胞，而这个细胞可能什么都不知道..........

乍看上去我们的宇宙的运动必有某种目的，因为存在则是为了目的而我们的宇宙确实那样的真真实实存在着。而仅这样想象一下又有何不可呢？毕竟我们的认知还是很有限的我们所知的还不到宇宙内部的5%，全部的宇宙是什么样的我们并不知情。宇宙是什么更是无从得知。对于宇宙是什么？是生物吗？还是仅仅是为了孕育生命的存在而默默的存在着的呢？

四、如果没有人类，那么宇宙存在的意义是什么？

这个问题似乎陷入了人类中心主义，我们人类的存在的 历史 不过只有几百万年的 历史 ，DNA与化石证明，人类大约在300万年前起源于非洲。而科学家们认为，宇宙起源于约138亿年之前的大爆炸，它的 历史 包括起点、40万年的初期膨胀、近4亿年的黑暗期、出现恒星、星系和行星发展期、含有暗物质与暗能量的加速膨胀期。

事实上，不管有没有人类存在，宇宙就是一种客观的存在。在我们存在的138亿年间，宇宙每时每刻都在显示自己独特的魅力，各种各样的物理变化、化学变化都在发生着，不以任何人的意志为转移。

我们对于宇宙的了解还很粗浅，就算自己所在的太阳系的很多情况，人类都没有了解清楚，宇宙的各种粒子在运行？暗物质是否存在？宇宙之外是什么？宇宙的未来是什么？到底有没有外星人，外星人的形态是如何的？很多问题都是未解之谜，也许要等我们的后代在几百年，几千年，甚至几万年后才能把宇宙的秘密搞清楚。

而且还有一个问题，那就是我们人眼看出去的宇宙就是真正的宇宙么？我们的视觉、听觉、触觉也是人体内部的大量化学反应和物理反应的结果，只不过我们很自信地认为我们眼中的宇宙就是最正统的宇宙，也许其他高等生物眼中还有另一种绚丽多姿的宇宙模样。

人类是宇宙运行过程中偶然塑造的一个产物，人类在不断地加深对于宇宙的了解，未来的人类会是一个什么样的命运还是未知，也许我们会一直在地球生存，直到太阳系的毁灭，也许我们会移居到宇宙的其他角落，当然还有一种最坏的结果，那就是也许有一天我们会全体灭绝。返回搜狐，查看更多

我们的存在或许只是宇宙存在史上的一次巧合之作又或者是真正意义上的锦上添花。我们的 科技 突飞猛进的未来期望我们终有一日可以解开宇宙的终极谜题。

你最恐惧的是什么呢？
我嗜好重口味的东西，硬是用暴力美学的幌子也好，就是看小清新的日本轻小说，都偏爱重口与小清新混合的樱庭一树。
所以，我想你对恐惧的期盼，应该也是止步于人性之恶、女巫的力量、扼住喉咙的恶意诅咒、鬼魂的怨念、穿越伦理的妄常、心境的游移，亦或是失去日常的一切迎面冲击的血腥惊悚么？
这些恐惧，只要你欣赏的时候，是一个艳阳天，你出去看看绿油油的叶子

⑥ 宇宙中的长城是怎样的

宇宙长城并不是指某个星系，而是一大群星系的集合。星系有成群出现的现象，这叫星系群；而星系群也有成群出现的现象，叫作超星系团。例如我们的银河系就属于本星系群，本星系群是本超星系团的成员之一。

通过观测发现，宇宙中大量的星系都集中在一些特定的区域上，在这种极大的尺度结构上看去就像是长长的城墙，所以叫“宇宙长城”，这可比星系的尺度要大得多。这个结构长约7.6亿光年，宽达2亿光年，而厚度为1500万光年，俨然就是一条不规则的薄带子的样子。天文学家们形象地称呼它为“长城”，后来被人称为“格勒—赫伽瑞长城”。

多年来，美国天体物理研究中心的科学家约翰•赫伽瑞和玛格特•格勒一直不断研究，他们利用首创的三度空间图像可以推测宇宙建立在许多巨大空间的周围。这些空间看起来就像洗脸盆里的肥皂泡，而大大小小的星系就依附在“泡沫”上。有的“肥皂泡”相当大，直径达到15亿光年。

这些“肥皂泡”怎样产生的呢？构成星系的物质是如何空出这么巨大区域来的呢？此类问题在科学界引起了激烈争论。有人认为，是大爆炸将物质从空间中心推向四周，从而形成“泡”状。这种说法存在很大问题，它无法解释物质怎么跑完这么长的路程，并形成这么巨大的空间。

这道肉眼看不见的曲线形的“长城”，离地球大约2亿—3亿光年。由于距离遥远，它在一般的天文摄影照片上也显示不出来。它使人们了解到宇宙中最大的发光结构不是银河系中的超星系团。

⑦ 宇宙中最大的天体结构究竟有多大

宇宙中存在着很大的事物或者结构，它们的尺寸远远大于地球，也远远大于太阳。因为它们实在太大了，用公里来表示它们的尺寸显得很不方便，这就需要用到光年。一光年，即光在一年内传播的距离，大约为9.5万亿公里。

比邻星距离我们4.2光年，即40万亿公里，音速飞机飞完这段距离需要370万年的时间。如果觉得这个距离很远，那来看看银河系的大小，银河系的宽度达到了10万光年。然而，银河系的宽度仅仅是宇宙中已知最大物体宽度的0.001%。

一个不应该存在的巨大结构

宇宙中最大的东西极其庞大，它超越了我们对大小的感知，那就是宽度高达100亿光年的武仙-北冕座长城，这是银河系宽度的10万倍，太阳直径的7亿亿倍。相比之下，可观测宇宙的预估半径为465亿光年。

天文学家把这个巨大的结构称作武仙-北冕座长城，它最近的地方距离我们96亿光年，最远的地方距离我们105亿光年。这意味着这个结构在100亿年前就已经存在了，那时宇宙才诞生大约38亿年左右。在早期的宇宙中，出现如此庞大且复杂的结构让天文学家困惑不已。迄今为止，天文学家对于这个巨大结构如何形成还不清楚。

⑧ 把原子放大无数倍，是否可以看到一个“微观宇宙”呢

“原子”是化学中最小的组成部分，但是在物理学中原子是可以分割的，因为随着科学的进步，科学家发现原子也是有构造的。粒子是物理学中最小的组成状态，一开始被称为“基本粒子”，但是随着深入研究，在很多的粒子中也存在着内部构造，基本粒子一词就被抛弃，现在的粒子是一种概念上的模型，因为已经有上百种不同的粒子被我们发现。

由此可以发现，科学家一直试图寻找的“最小”几乎是不存在的，自然界中的一切似乎都可以无限的分割缩小，微观到一定程度后，我们的物理体系就会失效，人类的观察和知识体系或许存在局限性，但是微观世界中可能永远都会存在更小的组成部分，由此有人提出了一个观点，我们生存的宇宙，有没有可能是一个原子呢？把一个原子放大1000倍，会出现一个微观宇宙吗？

如果不是列文虎克发明显微镜，人类还无法知道微生物和细菌的存在，很多新技术都会改变人类对宇宙的看法，或许在未来科技快速发展，人类可以看到更加微观的世界，发现原子中隐藏的奥秘也是很有可能的。

⑨ 神经与神经元之间的区别是什么

神经与神经元之间的区别：

1、概念不同：

神经：是由聚集成束的神经纤维所构成，而神经纤维本身的构造是由神经元的轴突外被神经胶质细胞所形成的髓鞘包覆。

神经元：即神经细胞，是神经系统最基本的结构和功能单位。

2、功能不同：

神经：即神经纤维构成的组织，把脑和脊髓的兴奋传给各个器官，或把各个器官的兴奋传给脑和脊髓。

神经元：接受刺激，产生兴奋并传导兴奋。

(9)宇宙长城和神经元区别扩展阅读：

根据神经元的机能分类：

1、感觉（传入）神经元：

接受来自体内外的刺激，将神经冲动传到中枢神经。神经元的末梢，有的呈游离状，有的分化出专门接受特定刺激的细胞或组织。分布于全身。

在反射弧中，一般与中间神经元连接。在最简单的反射弧中，如维持骨骼肌紧张性的肌牵张反射，也可直接在中枢内与传出神经元相突触。

一般来说，传入神经元的神经纤维，进入中枢神经系统后与其它神经元发生突触联系以辐散为主，即通过轴突末梢的分支与许多神经元建立突触联系，可引起许多神经元同时兴奋或抑制，以扩大影响范围。

2、运动（传出）神经元：

神经冲动由胞体经轴突传至末梢，使肌肉收缩或腺体分泌。传出神经纤维末梢分布到骨骼肌组成运动终板；分布到内脏平滑肌和腺上皮时，包绕肌纤维或穿行于腺细胞之间。

在反射弧中，一般与中间神经元联系的方式为聚合式，即许多传入神经元和同一个神经元构成突触，使许多不同来源的冲动同时或先后作用于同一个神经元。即为中枢的整合作用，使反应更精确、协调。

3、联络（中间）神经元：

接受其他神经元传来的神经冲动，然后再将冲动传递到另一神经元。中间神经元分布在脑和脊髓等中枢神经内。它是三类神经元中数量最多的。

其排列方式很复杂，有辐散式、聚合式、链锁状、环状等。神经元间信息传递的接触点是突触。复杂的反射活动是由传入神经元、中间神经元和传出神经元互相借突触连接而成的神经元链。

在反射中涉及的中间神经元越多，引起的反射活动越复杂。

人类大脑皮质的思维活动就是通过大量中间神经元的极其复杂的反射活动。中间神经元的复杂联系，是神经系统高度复杂化的结构基础。

⑩ 神经与神经元之间的区别是什么

区别：

1、构成不同

神经：由高度分化的细胞构成。

神经元：由神经胶质细胞构成。

2、形成方式不同

神经：神经纤维构成了神经。

神经元：神经细胞。

3、分类不同

神经：。神经又分为运动、感觉、混合神经。

神经元：按神经元突起数目分类：单极神经元，双极神经元，多极神经元。按神经元功能分类：感觉神经元(传入神经元)，运动神经元(传出神经元)，联络神经元(中间神经元)。

4、形态不同

神经：由运动神经的轴突或感觉神经元的长树突(两者统称为轴素)与包在它外表的神经胶质细胞构成。

神经元：是由细胞体和突起两部分组成。

① Why is it said that the universe may be the cells of a giant creature?

Obviously not. People always use analogy thinking to imagine things, thus falling into the error of thinking inertia. Imagine what this seven or eight-year-old child can imagine. Wouldn't countless scientists from ancient times to the present have not thought of it? It must be scientists who have ruled out this statement after research.
If you think about it carefully, you will realize that cells mainly rely on division to reproduce. Does the universe rely on division to reproduce? The universe does not even have a process of division. Moreover, the trajectory of the universe and cells are also different.
This problem is the same as if you found that copper is conductive and gold is conductive, and their colors are very similar, so you think copper is equal to gold, it is a fallacy caused by analogical thinking.

② The extinction of human beings will not affect the operation of the universe. What are human beings to the universe?

Human beings are insignificant to the universe, just like a grain of sand. . With the development of earth's civilization to this day, human beings consider themselves to be great beings, but many precious lives that appear in the universe are beyond human exploration. In the vast and boundless universe, human beings are as small as a grain of sand in the desert. The best is not worth mentioning.

So for people, the existence of the universe is an insignificant thing in practical terms. Although humans have dominated the earth through hundreds of millions of years of evolution, if humans do die one day, there will be a new population on the earth to replace humans. Therefore, humans are not as important to the universe as to the earth itself. The earth is not so important, so our existence in the universe is actually very small, and the value of our existence in the middle of the universe is basically non-existent.

③ The neurons in the universe are very similar to those in the brain, so will the universe be a living entity?

The birth of the universe has always been a puzzle that has puzzled everyone. Human beings still have to explore the universe. Dating back to ancient times, human beings had limited technology at that time and could not enter the universe to take a look at its true appearance. Therefore, everyone thought that the universe was a place where gods lived. After entering modern society, the advancement of productivity created many astronomical telescopes and aerospace aircraft. About the secrets of the universe, everyone has just begun to understand the universe. However, there are many mysteries waiting for humans to uncover. For ancient people, modern people can at least see what the universe looks like

< p>This conclusion overturned everyone’s imagination. After all, in everyone’s perception, the universe is just an ordinary nerve cell. If the universe is a relatively mature brain, then do humans still exist in this brain? The same super civilization, where are they now?

④ What is the difference and connection between nerves and neurons

Neurons, also known as nervous tissue, are the basic units that constitute the structure and function of the nervous system. Neurons are cells with long processes, which consist of a cell body and cell processesComposition
Nerve: A tissue composed of nerve fibers, which transmits the excitement of the brain and spinal cord to various organs, or transmits the excitement of various organs to the brain and spinal cord
Neurons, also called nerve cells, are the components of nerves The basic unit of system structure and function.
Nerve is a system composed of neurons and media; nerve is a system.
The reason why nerves are often used instead of systems is because nerves themselves are a system concept. According to the definition of physiological psychology, nerve is a system composed of neurons, that is, neuron system. Among them, neurons are the basis of the nervous system

According to the definition of physiological psychology, nerves are systems composed of neurons, that is, neuronal systems. Neurons are the basic functional structural units of the nervous system. Neuron definition: The structural and functional unit of the nervous system of higher animals. Includes cell body, axon and dendrites. Introduction Neurons, also known as nervous tissue, are the basic units that constitute the structure and function of the nervous system. Neurons are cells with long processes, which are composed of cell bodies and cell processes. Cell bodies are located in the brain, spinal cord, and ganglia, and cell processes can extend into various organs and tissues throughout the body. The cell body is the part of the cell containing the nucleus. Its shape and size vary greatly, with a diameter of about 4 to 120 microns. The nucleus is large and round, located in the center of the cell, with less chromatin and obvious nucleoli. There are patches of extranuclear chromatin (formerly known as Neal bodies) in the cytoplasm, as well as many neuronal fibers. Cell processes are elongated parts extending from the cell body and can be divided into dendrites and axons. Each neuron can have one or more dendrites, which can receive stimulation and transmit excitement to the cell body. Each neuron has only one axon, which carries excitement from the cell body to another neuron or to other tissues, such as muscles or glands.


Neuron: Neuron is a nerve cell, which is a highly differentiated cell. It has the function of sensing stimuli, conducting impulses and integrating information. It is the basic unit of the morphological structure and function of the nervous system. 2 , Morphological structure of neurons: Neurons are composed of two parts: cell body and processes. 3. Classification of neurons: (1) Classification according to the number of neuron processes: unipolar neurons, bipolar neurons, multipolar neurons (2) Classification according to neuron function: sensory neurons (afferent neurons), motor neurons (efferent neurons), contact neurons (interneurons). (2) Nerve fibers: Nerve fibers are composed of motor nerves It is composed of the axon or the long dendrite of a sensory neuron (both are collectively called axons) and the glial cells surrounding it. Nerve fibers are divided into myelinated nerve fibers and unmyelinated nerve fibers. To put it bluntly, they are neurons. The protruding part is part of the nerve fiber. Nerve fibers make up nerves. Nerves are divided into motor, sensory, and mixed nerves. in the structure of the human brain. The cell bodies of neurons make up part of the gray matter. Nerve fibers constitute part of the white matter

⑤ The universe is so big, how can humans be considered a cell in the universe, or not even a cell

Well, that’s the question.

Let’s not talk about the universe first, let’s talk about the solar system first. Voyager 1, launched in 1977, has been flying for 42 years so far, and it is flying at 17 kilometers per second, which is equivalent to It only takes one minute from Beijing to Shanghai. At this speed, it has just flown out of the solar system. You heard me right, just a small solar system.

Continue to increase the scale, the Milky Way.

It goes without saying how big the Milky Way is. It takes 8 hours for light to travel through the Solar System and 100,000 years to travel across the Milky Way.

How fast is the speed of light? 300,000 kilometers per second!

What is this concept? A concept that humans will never understand

In 1 second, light can fly around the earth 7.5 times. It is really flying for fun. The earth is really too small.

What about flying to the Milky Way? 100,000 years, are you afraid?

Really, the Milky Way is only that big, let alone other galaxies, the Andromeda Galaxy, etc., there are also galaxy clusters on the galaxies, and galaxy clusters...

Let’s not talk about it anymore, because humans can never understand how big the universe is, forever and ever...

1. If the universe is a living entity, then who are humans?

The answer is so amazing

Whenever we look up at the beautiful and vast starry sky, we will have a sense of seeing the Buddha, who is the only one in the sky and on the earth. The sense of intellectual loneliness mentioned by the Illuminati is actually very similar to the infinite loneliness and insignificance we have when facing the universe. The universe is so huge, and we humans are so small. It may be difficult for us to understand the gap between the universe and humans, and we can only describe ourselves in a very small way. But human beings have always been exploring this huge universe, spending our life journey to uncover its veil.

On the Internet, scientists once raised an interesting topic. If the universe is a huge life form, then what are the humans in it? This answer seems to be filled with a sense of scientific banter. Human beings may be an amazing species on earth, but in front of such a great universe, we have no comparison. In terms of volume, if the universe is a huge life, then we humans may not even be able to fit a single cell or atom. So what exactly do humans do in the universe?

In fact, this question also involves philosophical thinking in the field of science. Scientists have begun to think about life forms in the universe a long time ago. Astronomers seem to have discovered certain celestial bodies in the universe. Some unusual phenomena occurred. whenScientists had this idea when they discovered the Great Wall of the Universe. The so-called Great Wall of the Universe is a cosmic nebula that stretches for thousands of light-years between the universe. They are the precursors of the formation of galaxies in the universe. Celestial bodies are entangled in this huge continuous nebula. They are like the meridians of the universe, shining brightly in the dark starry sky, like the impulses of neurons in the human brain. The universe really seems to be a huge living body with its own life structure, and we are just a tiny part of it.

But although human beings may be just an existence so small that they cannot even be counted as molecules in the structure of the universe, human beings are unique. In the entire inorganic world behind, human beings are the only unique existences that have their own thinking and can create their own language and characters. We are the only life. Although we cannot compare with the vastness of the universe, we can write our own uniqueness. Leave your own footprints in this vast universe.

Although the universe is vast and spectacular, if there are no intelligent creatures like humans to write and record it, its existence may not really be that meaningful. We are insignificant to the universe, but unique to humans. Moreover, the universe is only in a stable state of development after all, and its future possibilities are unpredictable. However, human beings have endless explosive power. We can create one development miracle after another, and we may not be able to stand on the same footing as him in the future. Have a conversation. Human beings are small but also great and unique in the universe.

2. How insignificant are human beings compared to the universe?

Let me compare with a set of numbers: one solar energy can accommodate 1.3 million earths, one galaxy can accommodate 100 billion suns, a small galaxy cluster can accommodate 40 galaxies, and a galaxy cluster can accommodate 100 A small galaxy cluster, one galaxy can accommodate 1 billion galaxy clusters, and a super galaxy cluster can accommodate dozens of galaxies...

It can be seen from this set of numbers that compared to the universe, human beings are How small, even so small that it can be ignored. So, if human beings are so small, what is the meaning of survival? This question is very interesting, but I can tell you clearly that the significance of human survival is very important. There is a saying in Buddhism: One leaf, one Bodhi, one flower, one world. In other words, even a leaf or a flower is a universe, a world. For our human body, it can even be called a small universe.

Think about it, what is our human body made of? They range from skin, bones and organs to cells, protons and atoms, and even countless bacteria are present in every corner of the body. So, can we say that the smallest units of the human body have no value? In fact, it is these smallest units that make up the human body.

Therefore, although we are small to the universe, we are the most basic building blocks of the universe. Without these tiny organizations, the universe would not exist. And when we do things according to the laws of the universe, we meet the needs of the growth of the universe. Therefore, live a good life. We cannot do without the universe, and the universe cannot do without us!

3. What is the universe? Where did the universe come from and where is it going?

Modern science and technology allow us to know that the current observable age of the universe is 13.82 billion years. The latest research believes that the diameter of the universe can reach 92 billion light-years or even larger. The Big Bang originated from a singularity about 13.8 billion years ago. And he is still growing without limit.

What is the singularity? Where does the singularity explode?

A Big Bang with a singularity 13.8 billion years ago created everything we use and see today. The universe has infinite possibilities, and the Big Bang with a singularity is a phenomenon that never existed. to some creative process.

The universe we observe is a universe in which matter exists. To this day, we have not been able to figure out our position and purpose in the universe. The diameter of the universe considered by the institute to be 92 billion light-years is only our observable universe. To know what the observable universe is, the observable universe actually refers to the range of the universe that we can detect using the most advanced equipment and instruments. It is conceivable that there must be unimaginably vast spaces within our observable space. These spaces may never be observable by us, because there will never be a lack of light emitted there to reach the earth.

Because of the Big Bang, we have the full picture of the universe that we can see today. Every night we look up into the deep space, at the far, deepest depths of the universe. Events that astonish us as little people are happening all the time.

In November 2009, astronomers discovered a huge galaxy cluster composed of previously unknown galaxies in a distant region of the universe. The discovery of a huge galaxy cluster will help astronomers understand the potential cosmic web. "Skeleton"

The universe is a huge "cosmic web" composed of many galaxies strung together in filaments or tendrils. The filaments of the cosmic web are held together by dark matter. The cosmic web is considered to be composed of densely packed funnel-shaped galaxies, gas and dark matter in the universe, like a chaotic "intergalactic highway". It looks very much like a gene or cell in our body. Yes, this is the cosmic neural network.

This is the cosmic web that humans have observed so far, which is large enough to surprise anyone. Our location is the same. We are at a certain location inside the universe.In the Virgo super-galaxy group in the moving cosmic web, this super-galaxy group is also undergoing a revolution and rotation around the cosmic web.

We are in what we consider the Local Group of Galaxies in this supercluster. The Local Group of Galaxies refers to the Milky Way and the adjacent Andromeda Galaxy, the Magellanic Cloud, and other 30 galaxies. formed a smaller group. A group of galaxies including the Milky Way. All galaxies in the Local Group cover an area about 10 million light-years in diameter.

There are more than 30 galaxies that rotate and orbit around the supercluster.

And in an inconspicuous corner of this super-galaxy group is the Milky Way that we see when we look up at the sky at night. The stars we see at night are all within the scope of the Milky Way. Even the Milky Way, which is 100,000 light-years in diameter, also has its own revolution and rotation.

The last thing mentioned is our home, our solar system, a home that no one has left in the hundreds of thousands of years of human development.

The Milky Way is a barred spiral galaxy with a diameter of about 100,000 light-years and containing 100 to 400 billion stars. The sun is a typical star in the Milky Way. It is located on the branched cantilever Orion Arm, 26,100 light-years away from the center of the Milky Way. The solar system moves at a speed of about 240 km/s and completes one revolution every 226 million years.

The eight planets in the solar system all orbit in nearly the same plane and in nearly circular orbits, revolving in the same direction around the sun. Except for Venus, the other planets rotate in the same direction as their revolution. Most comets orbit the sun in the same direction, most of them have elliptical orbits, and their orbital periods are generally relatively long.

Celestial bodies orbiting the sun are divided into three categories: planets, dwarf planets and small solar system bodies.

Planets are celestial bodies that orbit the sun and are massive enough.

Our solar system is such an existence that it is already very big for us. But in fact, it is just a piece of dust and insignificant to our universe.

From our earth to the solar system to the Milky Way to the Local Group of galaxies to the Virgo Supercluster, they are all moving. These movements seem to be insignificant to the existence of the universe, and to this day No one can tell what the purpose of the universe is. So these movements are like a vital presence. The friction, collision, engulfment, and competition of movement itself all amaze us.

He made us see how insignificant and yet how crucial our existence is.

There are some recent branches of theory that suggest that our universe looks more like a giant creature, a creature that we will never be short of understanding.

Yes, when we talk about the universe, humans are often in awe, because the universe is so big, and what humans understand is only superficial. But as far as current scientific research is concerned, the universe may not be As a living entity, most scientists believe that the universe was created out of nothing and evolved slowly from a singularity. So let me take a step back and say, if the universe is really a form of life that humans do not understand, then what will happen to it? The impact on human beings is probably huge and difficult to accept. Just imagine, human beings are just a cell in this living body, and this cell may not know anything...
< br /> At first glance, it seems that the movement of our universe must have some purpose, because existence is for purpose, and our universe does indeed exist like that. And why not just imagine it like this? After all, our knowledge is still very limited. We know less than 5% of the inside of the universe. We don’t know what the entire universe is like. There is no way of knowing what the universe is. For what is the universe? Is it a living thing? Or does it exist silently just to nurture life?

4. If there are no human beings, what is the meaning of the existence of the universe?

This issue seems to fall into anthropocentrism. The history of our human existence is only a few million years old. DNA and fossils prove that humans originated in Africa about 3 million years ago. Scientists believe that the universe originated from the Big Bang about 13.8 billion years ago. Its history includes the starting point, the initial expansion of 400,000 years, the dark period of nearly 400 million years, the emergence of stars, galaxies and planets, and the development of dark matter and planets. A period of accelerated expansion of dark energy.

In fact, regardless of whether humans exist or not, the universe is an objective existence. During the 13.8 billion years of our existence, the universe has shown its unique charm every moment, and various physical and chemical changes are taking place, regardless of anyone's will.

Our understanding of the universe is still very superficial. Even though humans do not understand many aspects of the solar system in which they live, how are the various particles in the universe moving? Does dark matter exist? What is beyond the universe? What is the future of the universe? Are there aliens? What are their forms? Many problems are unsolved mysteries, and it may take hundreds, thousands, or even tens of thousands of years for our descendants to figure out the secrets of the universe.

And there is another question, that is, is the universe seen by our human eyes the real universe? Our vision, hearing, and touch are also the result of a large number of chemical reactions and physical reactions inside the human body. However, we are very confident that the universe in our eyes is the most orthodox one. Maybe there is another kind of gorgeousness in the eyes of other higher organisms. of the universe.

Human beings are the universeIt is a product accidentally shaped during the operation of the universe. Human beings are constantly deepening their understanding of the universe. It is still unknown what kind of fate human beings will have in the future. Maybe we will continue to survive on the earth until the destruction of the solar system. Maybe we will emigrate. To other corners of the universe, of course there is a worst-case outcome, that is, maybe one day we will all become extinct. Return to Sohu to see more

Our existence may be just a coincidence in the history of the universe, or it may be the icing on the cake in a real sense. Our technological advancements in the future hope that we will one day be able to solve the ultimate mysteries of the universe.

What are you most afraid of?
I am fond of heavy-flavored things, even if they use the guise of violent aesthetics. Even when I read fresh Japanese light novels, I prefer Kazuki Sakuraba who mixes heavy-toned and fresh.
So, I think your expectation of fear should also be limited to the evil of human nature, the power of witches, the malicious curse that strangles the throat, the resentment of ghosts, the perversity of transcending ethics, the wandering state of mind, or Is it a bloody horror of losing everything in daily life and being hit head-on?
As long as you appreciate these fears, it is a sunny day and you go out to look at the green leaves

⑥ What does the Great Wall in the universe look like

The Great Wall in the universe is not It does not refer to a single galaxy, but a collection of large groups of galaxies. Galaxies can appear in groups, which are called galaxy groups; and galaxy groups can also appear in groups, which are called superclusters. For example, our Milky Way belongs to the Local Group of galaxies, which is a member of the Local Supercluster.

Through observation, it is found that a large number of galaxies in the universe are concentrated in some specific areas. This extremely large-scale structure looks like a long city wall, so it is called the "Great Wall of the Universe". This is much larger than the size of a galaxy. This structure is about 760 million light-years long, 200 million light-years wide, and 15 million light-years thick, just like an irregular thin belt. Astronomers vividly called it the "Great Wall", and later it was called the "Gela-Hegari Great Wall".

For many years, scientists John Hegarry and Margot Geller of the American Center for Astrophysics have been conducting research. They used the first three-dimensional space images to speculate that the universe was built on many huge spaces. around. These spaces look like soap bubbles in a washbasin, with galaxies large and small clinging to the bubbles. Some "soap bubbles" are quite large, reaching 1.5 billion light-years in diameter.

How do these "soap bubbles" come about? How did the material that makes up galaxies vacate such a huge area? Such questions are hotly debated in the scientific community. Some people believe that the big bang pushed matter from the center of space to the surroundings, forming a "bubble" shape. There are big problems with this statement. It cannot explain how matter can travel such a long distance and form such a huge space.

This is visible to the naked eyeThe missing curve-shaped "Great Wall" is about 200 million to 300 million light years away from the earth. Due to its great distance, it cannot be shown in ordinary astrophotography photos. It led to the understanding that the largest luminous structures in the universe are not the superclusters of galaxies in the Milky Way.

⑦ How big is the largest celestial structure in the universe?

There are very large things or structures in the universe, and their sizes are much larger than the earth and the sun. Because they are so large, it is inconvenient to express their size in kilometers, which would require light-years. One light year, the distance that light travels in one year, is approximately 9.5 trillion kilometers.

Proxima Centauri is 4.2 light-years away from us, or 40 trillion kilometers. It would take a sonic aircraft 3.7 million years to fly this distance. If you think this distance is very far, then look at the size of the Milky Way. The width of the Milky Way is 100,000 light-years. However, the width of the Milky Way is only 0.001% of the width of the largest known object in the universe.

A huge structure that should not exist

The largest thing in the universe is so huge that it surpasses our perception of size, and that is the Wu Xian, which is 10 billion light years wide - The Great Wall of Corona Borealis is 100,000 times the width of the Milky Way and 7 billion times the diameter of the Sun. By comparison, the estimated radius of the observable universe is 46.5 billion light-years.

Astronomers call this huge structure the Great Wall of Hercules-Corona Borealis. Its closest point is 9.6 billion light-years away from us, and its farthest point is 10.5 billion light-years away. Light years. This means that this structure existed 10 billion years ago, when the universe was only about 3.8 billion years old. The emergence of such large and complex structures in the early universe has baffled astronomers. Until now, astronomers have not understood how this giant structure formed.

⑧ If you magnify atoms countless times, can you see a "microscopic universe"?

"Atoms" are the smallest components in chemistry, but in physics, atoms can Divided, because with the advancement of science, scientists discovered that atoms also have structures. Particles are the smallest component state in physics. They were called "elementary particles" at first. However, with in-depth research, many particles also have internal structures. The term "elementary particles" was abandoned. Today's particles are A conceptual model because hundreds of different particles have been discovered.

It can be found from this that the "minimum" that scientists have been trying to find almost does not exist. Everything in nature seems to be infinitely divided and reduced. When the microscopic reaches a certain level, our physical system will Failure, human observation and knowledge systems may have limitations, but there may always be smaller components in the microscopic world. Therefore, someone has put forward a point of view, is it possible that the universe we live in is an atom? If you magnify an atom 1000 times, will a microscopic universe appear?

If Leeuwenhoek had not invented the microscope, humans would still not be aware of the existence of microorganisms and bacteria. Many new technologies will change humans’ view of the universe. Perhaps in With the rapid development of science and technology in the future, humans can see a more microscopic world, and it is very possible to discover the mysteries hidden in atoms.

⑨ The difference between nerves and neurons is What

The difference between nerves and neurons:

1. Different concepts:

Nerves: are composed of nerve fibers gathered into bundles, and The structure of the nerve fiber itself is that the axon of the neuron is covered by the myelin sheath formed by glial cells.

Neuron: Nerve cell, the most basic structural and functional unit of the nervous system.

2. Different functions:

Nerve: a tissue composed of nerve fibers, which transmits the excitement of the brain and spinal cord to various organs, or transmits the excitement of various organs to the brain and spinal cord .

Neurons: receive stimulation, generate excitement and conduct excitement.

(9) Extended reading on the difference between the Great Wall of the Universe and neurons:

Classification based on the function of neurons:

1. Feeling (Afferent) neurons:

Receive stimulation from inside and outside the body and transmit nerve impulses to the central nervous system. Some of the neuron terminals are free, and some differentiate into cells or tissues that are specialized to receive specific stimuli. Distributed throughout the body.

In reflex arcs, they are generally connected to interneurons. In the simplest reflex arc, such as the muscle stretch reflex that maintains skeletal muscle tone, it can also directly synapse with efferent neurons in the center.

Generally speaking, the synaptic connections with other neurons after entering the central nervous system are mainly divergent, that is, they establish synaptic connections with many neurons through the branches of axon terminals. Synaptic connections can cause many neurons to be excited or inhibited at the same time to expand the range of influence.

2. Motor (efferent) neurons:

The nerve impulse is transmitted from the cell body to the terminal via the axon, causing muscle contraction or gland secretion. Efferent nerve fiber endings are distributed to skeletal muscles to form motor end plates; when distributed to visceral smooth muscles and glandular epithelium, they surround muscle fibers or travel between gland cells.

In a reflex arc, the general way of connecting with interneurons is aggregation, that is, many incoming neurons form synapses with the same neuron, so that many impulses from different sources act on the same neuron at the same time or one after another. same neuron. It is the integration function of the center, making the response more precise and coordinated.

3. Contact (intermediate) neurons:

Receive nerve impulses from other neurons, and then transmit the impulses to another neuron. Interneurons are distributed in the central nervous system such as the brain and spinal cord. It is the most numerous of the three types of neurons.

The arrangement is very complicated, including divergence type, convergence type, chain type, ring type, etc. The point of contact for information transmission between neurons is the synapse. Complex reflex activity is a neuron chain composed of afferent neurons, interneurons and efferent neurons that are connected by synapses to each other.

The more interneurons involved in a reflex, the more complex the reflex activity is.

The thinking activity of the human cerebral cortex is an extremely complex reflex activity through a large number of interneurons. The complex connections between interneurons are the structural basis of the highly complex nervous system.

⑩ What is the difference between nerves and neurons?

Differences:

1. Different compositions

Nerves: highly differentiated composition of cells.

Neurons: composed of glial cells.

2. Different formation methods

Nerves: Nerve fibers constitute nerves.

Neuron: Nerve cell.

3. Different classifications

Nerve:. Nerves are divided into motor, sensory, and mixed nerves.

Neurons: Classified according to the number of neuron processes: unipolar neurons, bipolar neurons, and multipolar neurons. Classified by neuron function: sensory neurons (afferent neurons), motor neurons (efferent neurons), contact neurons (interneurons).

4. Different shapes

Nerve: composed of the axon of the motor nerve or the long dendrite of the sensory neuron (both are collectively called axon) and the nerve glue wrapped on its surface The composition of plasma cells.

Neuron: It is composed of two parts: cell body and processes.
