黑洞里面到底有什么,有没有可能是另一个宇宙的入口
黑洞里面到底有什么,有没有可能是另一个宇宙的入口
我觉得黑洞的另一头什么也没有,被吸入的东西,都会被里面的速度所撕裂,包括光,还是实物等,都被转化成了一种粒子,融入了黑洞之中,成为了黑洞的一部分.黑洞里没有时间,没有空间,也很难说清黑洞是以一种什们样的形势或者状态存在,一维,二维,或者是三维,没有人知道,人类也永远不可能知道,因为如果人类尝试着进去,那么就没有可能出来了.那个进去的人不能说她活着或者死了,因为他一旦进去后,整个人就不存在了.
这个问题貌似霍金都不能给你准确的答复！
现在科学家观测到在遥远的宇宙深处有一种天体叫类星体，因为其拥有远高于其本应具有的能量，科学家称为类星体， 有人认为这就是传说中的百洞，他和黑洞相反，黑东部允许任何物质逃离他的引力范围，而白洞不允许任何物质进入她的引力范围，而且在不断向宇宙空间抛撒物质，白洞与黑洞之间有一个虫洞相连接，即被黑东西入的物质从白洞喷出！...
不知道里面有什么,有可能是另一个宇宙的入口........有机会我去试试............
好好看，看得懂你真的很厉害了，不过看不懂也不要紧，关键是兴趣黑洞是什么 黑洞中隐匿着巨大的引力场，这种引力大到任何东西，甚至连光，都难逃黑洞的手掌心。黑洞不让任何其边界以内的任何事物被外界看见，这就是这种物体被称为“黑洞”的缘故。我们无法通过光的反射来观察它，只能通过受其影响的周围物体来间接了解黑洞。据猜测，黑洞是死亡恒星或爆炸气团的剩余物，是在特殊的大质量超巨星坍塌收缩时产生...
恩恩.我也去试试,说不定有一群美女.......
我也曾想过黑洞是两个宇宙间的通道,不过现在还是一个未解之谜,黑洞的引力太大了,科学家根本不可能进去探究嘛~~~~~现在想想,好像不可能
有可能，因为目前无法证明不是入口．
有可能是另一个3维空间 是不是宇宙 很难说啊
里面什么也没有，因为黑洞中什么都不存在了——包括时间、空间。
可能是通道
黑洞中什么也没有！
我认为还是可能的，因为虽然任何东西进入黑洞都会被那速度给撕裂，但是如果侥幸没事，那里没有我们意义上的时间和空间。就像北纬30度那一样，我感觉就像另一个空间的门，那么多失踪的东东 ，也许是进入了另一个时空，类似于黑洞给人的感觉。...
vnjjhjjh56j...
有可能，这种东西科学家都搞不清，只能是说有各种猜测。
空间发生扭曲了，还有什么不可能发生的?就好像我现在把门打开，一看到了美国一样。因为空间改变了~~~~也许黑洞里就是人们死后灵魂的聚集地，也是有可能的!最新研究表明：黑洞或为通往宇宙其它区域入口

艺术家描绘的超大质量黑洞。
　　【搜狐科学消息】据国外媒体报道，理论物理学家最新研究表明，黑洞的中心或许并不像当今认为的那样具有无限大的密度，而是通往宇宙其它区域的入口。
　　黑洞的引力是如此之强大，以至于光线都无法逃脱。黑洞通常是在恒星发生剧烈的超新星爆炸之后形成的。根据广义相对论，每一颗黑洞中心都有一个密度无穷大的“奇点”。“奇点”具有无穷大的性质意味着，空间和时间在那里停止。长期以来，科学家一直在寻求一种避免所有已知的物理定律在“奇点”处失效的方法。
　　根据最新的研究，黑洞的中心或许根本就不存在密度无穷大的“奇点”，这是一个基于圈量子引力理论的新发现。圈量子引力理论是一种试图把量子力学和广义相对论统一起来的主流理论。科学家认为，黑洞的中心仅仅是一个高度弯曲的时空区域。这也是长期以来，人们孜孜以求的用量子引力化解黑洞“奇点”的方法。
　　正如圈量子引力把宇宙大爆炸的“奇点”看做通往其它宇宙的桥梁一样，黑洞中的“奇点”可看做是通往宇宙其它区域的通道。
　　然而，目前科学家利用的模型还非常简单，仅仅由高度弯曲的时空构成，而不包含真实的物质。该模型是高度球对称的，而不像真实的黑洞那样由于具有自转，从而导致失去球对称结构。因此，科学家下一步的任务就是增加该模型的复杂性，把物质和非对称因素考虑进去，期待得到更加符合实际的结果。（编译：双螺旋）
