do you think that we can go back in time ???

Question

i think that two particles that are the same cannot be in the same time period or somethings going to happen.

to eugene. i belive thats a memory that we have not physcil travel

Answer 1

Time travel is possible....This is one of the three fabulous things which is proved by Einstein's special theory of relativity. It has been proved that at speeds comparable to light, time slows down!! So, if you are moving at 99% the speed of light, then, if for your twin on earth 20 years have passed, for you only 10 years would have passed!! So when you return to earth, you would be younger than your own twin!!! This is termed as "the twin paradox". This way time travel into future is possible theoretically...but practically it has not yet been figured out since to travel at speeds comparable to that of light is not a child's play! Now, scientists have even found a way to travel into past --- THEORETICALLY --- by passage through singularities. Singularities are weird things with ZERO VOLUME and INFINITE DENSITY. Singularities are known to be present at the cores of black holes. But now they also have been thought to be present near a black hole.
To know more, you would want to read more about relativity...and let me tell you, it is mind boggling but all the same FABULOUS!!!!

Answer 2

If time travel was possible, I think we would have seen some evidence of it by now (maybe people from the future would have visited us or something). Besides, I think time is a relative thing. There is no February 1, 2007 in the universe, time is a thing we use as measurement. Look at other animals as examples. Dog and cat years are shorter than human years, insects can live an entire life cycle in 24 hours (to us it's 24 hours, but to the insect it probably feels like years)

Answer 3

Richard Keating and John Hafele measured the effect of traveling at high speed on relative time dilation. They synchronized two atomic clocks and then flew one of them around the world. Upon landing the the clocks differed by 40 billionths of a second - just as Einstein predicted. Therefore if we could achieve speeds great enough then time travel would be possible, unfortunately the amount of energy required to propel a given mass grows exponentially as the speed increases.

Answer 4

If you subscribe to the Infinite Worlds / Infinite Possibilities theory (which assumes time is not linear, and that each and every branch of possibility exists in time and space though multiple dimensions) then yes. Time travel would place you in a similar though different "worldline" because of the choice involved, therefore the particles would not be the "same".

Answer 5

We can travel in the present time, but cannot go into the future nor the past time.
The element of travel exhists in the power of electrical impulses that are actually live encounters during OBE's.

People who have OBE"s are the best Government spies in the world.

Answer 6

If you could go back in time you could also go forward.
This would cause a major problem in that time machines would be a dime a dozen and every person and his brother would be jamming the passage ways of time.
Jesse James and John Dillinger would all be going ape!

Answer 7

I just read a book that discuss the same problem.It says that a way can be found on a tunnel named a wormhole.This wormhole is probably a gateway not just in another galaxy but another time as well.

Answer 8

Going back in time is a mystery. But I wonder once I experienced it but am not able to explain. It was just for a moment but I suppose it was thousands , or even more time back or forward where I was and I felt like a snap.

Answer 9

Prof Steve Hawking says time is said to have an arrow. Though some part of theory supports entropy does not.

Answer 10

Time travel is impossible. It is not something that can be toyed with like some physicists think. It's not an object.
