3、 a magical plot device.No actual science is thrown at the audience.After all,you are probably not watching life on mars(火星生活）or terminator salvation（终极者：救世主）for a lesson in theoretical physics.,Star trek（星际迷航）,If we learned anything about the physics of time and space form Richard Donner 1978 film S

7、rman,it s that if you fly around the earth really fast,you can reverse its rotation and roll back time.,Different attitudes towards Time Travel,Most Time Travel dramas are based on true history and the elements added to the stories make history more interesting and attractive.,While others argue tha

14、mer blockbusters to sensational science headlines,modern culture is constantly inundated with tales of Time Travel.,？,But when you boil down the physics involved,is it possible to travel through time?,There is no doubt that Albert Einstein is one of the most authoritative ones to answer this questio
15、n.,According to his theory of relativity,speed and mass are two major factors affect time.,Factor:,speed,A phenomenon called time dilation(时间膨胀效应)is the key here.,Time passes more slowly the closer you approach the speed of light-an unbreakable cosmic speed limit.,Factor:,speed,As such,the hands of
16、a clock in a speeding train would move more slowly than those in a stationary clock.The difference would not be humanly noticeable,but when the train is pulled back into the station,the two clocks would be off by billionths of a second.If such a train would attained 99.9%light speed,only one year wo
17、uld pass onboard for every 223 years back the train station.,Factor:,mass,Speed isnt the only factor that affect time.On much a smaller scale,mass also influence time.Time slows down the closer you are to the center of a massive object.,For example,a clock aboard an orbiting satellite experience tim
18、e dilation due to both the speed of its orbit and its greater distance from center of earths gravity.,According to Einsteins theory,Time Travel is possible theoretically,but it can not be achieved in the real world.,There are some other evidences for his opinion.,wormhole,About Wormhole(虫洞）,Wormhole
19、 is a little bit like a tunnel or shortcut between two distant points.For example,if you had a wormhole here in your room and you jumped through it you wouldnt come out on the street,you d maybe come out on the other side of the galaxy.,World-famous physicist Stephen Hawking has proposed that wormho
20、le occurring at a quantum level(量子能级)could theoretically provide a foothold for time travel.,Some people hold different views,For example,imaging going back in time and your kill your own mother.Then shed never give birth to you,and just how would you have been able to travel back in time to commit matricide in the first place?,A number of questions about Time Travel remain unanswered.Will time tourists form the future ever show up to help us out?We will just have to wait and see.,?,?,thank you,
