Traveling in Time
You cannot change the laws of physics ...but could physics actually enable us to travel through time?
It might sound crazy,but according to Einstein's theories,there's no logical reason why time travel isn't possible.
Time travel is clearly a trickier proposition than space travel,though.And prior to Einstein,it would have been deemed utterly impossible!That's because the old idea about time was that it was like a cosmic metronome keeping a regular and constant beat throughout the universe.And it was thought to move in one direction only .
However,what physicists now know is that time is rather more flexible than the old “ Clockwork Universe” ideas they had it.And it was Albert Einstein who set the cat among the pigeons.
Einstein's theories about time and space were revolutionary.He became a celebrity--and not just in scientific circles.It's only since he published his theories that scientists have been able to demonstrate that space and time really behave the way he said they did.
In 1971,after Einstein's death,two scientists were able to carry out a crucial experiment.They used two atomic clocks,synchronized them,and placed one on a plane,while the other stayed in the same location on Earth.The plane then flew around the world for 80 hours.According to Einstein's theory,the clock on the plane would be expected to have lost time,due to being in motion over 80 hours compared to the clock on the ground.When they brought the clocks together and made a comparison,the clock on the plane was indeed a few nanoseconds slower than the other clock.The experiment was replicated in 1996 with advanced technology,and it was proved again--with an even bigger time difference this time.Which proves that not only is time “ warp-able” ,but Einstein was arguably the greatest thinker the world has ever seen.
If it were possible,however,it would present some pretty knotty paradoxes...For example,what if someone or something traveled back in time and changed the ensuing future?And have you heard the one about the time traveller who dots back and forward in time and by means of various medical technologies is able to be his own father AND mother?And besides,if time travel is possible,where are all the people from the future--surely they'd want to come and meet us poor stranded 21st century beings?全文翻译

旅游时间
你不能改变物理定律...但物理实际上使我们能够穿越时间?
这听起来疯狂,但根据爱因斯坦的理论,就没有合乎逻辑的原因,时间旅行是不可能的.
时间旅行显然是一个复杂命题比太空旅行,但.之前,爱因斯坦,它会被认为根本不可能的!这是因为旧的观念的时候了,这是像宇宙节拍器保持定期和经常击败整个宇宙.并认为此举只是一个方向.
然而,物理学家现在知道的是,时间是比较灵活的比老的“发条的宇宙”的想法,他们它.这是爱因斯坦谁设置猫之间的鸽子.
爱因斯坦的理论,时间和空间是革命性的.他成了名人-不仅在科学界.这只是因为他出版了自己的理论,科学家已经能够证明,空间和时间的真正表现的方式向他表示他们.
在1971年后,爱因斯坦的死亡,两名科学家们能够进行实验的一个关键.他们用两个原子钟同步,并置于一个在飞机上,而其他留在地球上的同一位置.这架飞机随后飞往世界各地的80个小时.根据爱因斯坦的理论,24小时在飞机上预计将有失去的时间,由于是在运动超过80小时的时钟相比,在地面上.当他们把钟表在一起,并提出了比较,24小时在飞机上确实是一个几纳秒低于其他时钟.实验是在1996年推广先进技术,它再次证明-有一个更大的时间差这一次.这证明,不仅是时间“经能” ,但爱因斯坦被认为是最伟大的思想家世界上前所未有.
如果有可能,但是,目前一些非常棘手的矛盾...例如,如果某人或某事去回的时间和改变随后的未来?你听说有一个关于谁的时间由点回和前瞻性的时间和通过各种医疗技术能够得到他自己的父亲和母亲!而且,如果时间旅行是可能的,在那里所有的人从未来-当然他们会要来和我们见面穷人被困21世纪吗?
