The idea of time travel is fascinating and interesting. And certainly, the newer ideas about how the university system constructed, raised the possibility that more dimensions than the 3-dimesions of space and one dimesion of time that we used to hear in the university exist.

时光旅行既有趣又吸引人。当然,新观点指出宇宙组成有多维的可能性,人们认为在三维的基础上还有一维时间,自宇宙诞生之时就已开始的时间。

The ideas that are often used in fiction where you travel faster than the speed of light in order to change the past. For example at the end of superman 1, superman whizzes around the planet earth, because he is shocked that the Louis Lane's just died. In the great earthquake caused by nuclear explosion when Lex Lothor detonates something.

科幻小说中最常见的观点就是,当一个人的速度超越光速,他就能穿越时空改变过去。例如在《超人》1的结尾,超人不敢相信Louis Lane因核爆炸引发的地震而死去,他绕着地球飞行。

He breaks the light barrier, travels faster than the speed of light, and then the earth starts go backwards, all of a sudden, Lois Lane rises from the dead.

他打破了光的束缚,超越了光速,接着时空倒转,Louis Lane又活了过来。

The fanciful ideas of travelling backwards through time by moving faster than the speed of light. Simply, mathematically don't work.

超越光速穿越时空的这种奇幻的想法,从数学角度上看并不能实现。

Michael J.Fox put plutonium in his lorry and he rocked back the time while plutonium does not have the enough energy to drive the time machine. To energize a time machine, to bend time into a presser, to punch a hole in the fabricated space and time would require the energy of the star. One version of a time machine uses what's called a wormhole. Think of a looking glass in Alice Wonderland. That looking glass is the wormhole. What happens if you go back in time, and kill your parents before you're born. Well, if you kill your parents before you are born, how could you be born because you just kill your parents before you're born. If you go back within time, and you saved Abram Lincon from being assasinated, you would have essentially saved somebody else's Abram Lincon, your Aram Lincon died. If you change the fabricated time, you are changing another parallel universe. These people are genetically identical to the people of your past. But they're different.

Michael J.Fox将钚元素放入车中,结果扭曲了时间,因为钚并没有足够的能量驾驭时间机器。时间机器需要能量来将时间压缩成环状,在重组的时空中创造一个时空洞,而这需要来自恒星的能量。影视作品中有一个版本的时间机器运用了虫洞的能量。《爱丽丝梦游仙境》中的镜子就是虫洞。另外,如果你回到过去,杀死还没有生孩子的你的父母。也就是说,你杀死了还没有生你时你的父母,那么你又怎么会存在呢,因为你的父母在生你前就已经死了。而如果你穿越时空,解救了被刺杀的林肯,实际上,你解救的林肯将不再是未来世界中的“林肯”,而在你未来时空中的“林肯”还是死了的。如果你改变了过去的时空,你就改变了未来的平行世界。在这个平行世界中的人们和你的过去世界中的人看似一模一样,但实际上他们是不同的。

If I can go back any time in past to see any event, I think I will go back in the past about 3.5 billion years ago, to witness the creation of first molecules of life. I would like to go back to the time that the earth formed, that our sun formed and see how it was, and what exactly was the process that made it possible for our sun to collect together, and force of gravity in all that space dusts and gas coming together to form a star. When people aske: Is time travel just a philosophical structure or hypothetic or mathimatically show. The answer is it's a combination of them all.

如果我能回到过去的任何时间点,我想我会回到35亿年前去见证第一个生命分子的诞生。我想回到地球和太阳成型的时期去看看究竟,去看看到底是什么关键步骤使我们的太阳最终聚集成型,我想去见证宇宙尘埃和气体因引力和重力而聚集成星体。人们可能会问:时间旅行是属于哲学范畴,数学科学,还是一种科学假设。而答案就是这三者的结合。
