SEEING THROUGH TIME .....

This is not an assumption. This is a scientific fact. We are able to see the past through looking at the stars. The light from the distant stars takes a lot of light years to reach the Earth. Hence when we are looking at the beautiful starry sky in a clear night we are actually looking at the past of these stars. Astonishingly enough we are looking at a lot of different pasts simultaneously, as these stars are vastly different in regard to their distance from us

There are many conceivable ways of time travel, and many people who do and do not believe in them (such beliefs do not in fact change any laws of nature).

If time travel were assumed to be possible then many impossibilities would be assumed to appear. For example, if someone were to travel into the past and see himself as a child he could kill himself. Okay, so that would be a pretty dumb thing to do, but the possibility brings up a paradox. If he kills himself, then he could never go back in time and kill himself. The possibility of this situation might lead to believe that time travel into the past is not possible. In fact the only time a paradox could be assumed to happen is when someone travels backward in time, and if this travel proves to be possible it should eliminate the possibility of a paradox (by definition paradoxes never happen). In the above example the man would not be able to kill himself, no matter hard he tried, because he has already got to live into the future without killing himself. Someone who does not agree?

Isaac Newton's ideas were widely accepted and could be accurately applied to most of the universal calculations. It wasn't until a slight discrepancy in the observed Mercury orbit and the calculated one that scientists began to wonder if Isaac Newton was entirely correct. The Mercury orbit differed by exactly 42 arc seconds. Later when it was found that light always appeared to move with the same speed despite one's own velocity, combined with many other observations, the Newtonian universe began to crumble.

It was time for new ideas. Albert Einstein was full of them. His theory of relativity assumed that time was the fourth dimension, he introduced the concept of Space-Time. A large mass would bend the space around it and in doing so would create gravity (a Time-Space cartoon). This was a far fetch from original theories, but it predicted the Mercury orbit exactly. Later it was given further support by a test during an eclipse. The light from a star was bent as it came into the curved space created by the sun.

The time travel aspect of this comes from the curved space. When a mass bends the Space-Time it makes distances longer, it stretches the space. A spaceship traveling into the gravity of a large mass, a star, for example Sirus, going 100,000 miles per hour would look like it was traveling quite fast to someone outside the spaceship. Once the ship enters the gravity of Sirus, the ship would seem to slow down. It hasn't though, ship's computer states a constant velocity of 100,000 miles per hour. The person outside is watching the ship and the ship seems to stopp. The space around Sirus which appears to be an inch is actually, once you get there, 100,000 miles. The man inside the ship feels no differens and he continues to travel what seems to be 100,000 miles per hour, so his time must have slowed down. His hour becomes longer than it is to the observer. His clock still runs in a steady motion but it moves slower in comparison to the clock of the observer. This is called Time Dilation. In fact according to the theory of relativity, by moving at speeds close to the speed of the light, even if this happens in a train, the clock would slow down (in relation to the clock of an observer), and one could in this way travel forward in time.
