One thing you should know about is a guy named albert einstien and his theory of relaitivy, he was the one that proposed that distance and time are not absolute. the second thing that is important to know is that general relativity proposed that motion and gravity can affect the intervals of time and space. The last thing that you should know is the defination on an interval, which is a definite length of time marked off by two instants.

This Picture is of Albert Einstien, the guy who made the theory of relativity.

All the laws are the same when dealing with physics. Newton's theory of gravity was related to his thoughts on space and time, and he formalized his concept of the inertial frame. Later a guy named Maxwell had a theory that electricity and magnetism contained a single number for the speed of light. Einstein then went over the situations and came to the conclusion that maxwell was right and newton's theory was an approximation.

The first piece of evidence is that there is 1,079,253,000 km/hr with respect to all observers(David M. Harrison)

The second information supporting fact is Einstein's earlier theory of time and space, special relativity, proposing that distance and time are not absolute.(Alan Lightman)

The last piece of evidence is an experiment that has confirmed that light rays from distant stars were deflected by the gravity of the sun in just the amount he had predicted in his theory of gravity, general relativity.(Alan Lightman)

My reason for supporting the first evidence is knowing the number helps prove that they arn't just pulling numbers out of the air. Knowing this number shows that they arn't making everything up, and they are putting credible information in their website.

My reason for supporting the second piece of evidence is the information about time and distnace not being absolute. this information is on other sites and is not made up from random information.

My reason for supporting the last piece of evidance is that there is proof that Einstein did an experiment, and it is on other websites. I support this evidnce because it has been confirmed that light rays from distant tars were deflected by the gravity of the sun.

This picture is of the time on earth and of the time on a space ship in space.

The numbers and experiments show evidence and confirm that everything is real and not just made up. Time travel is technically possible but you can only ever move forward. There is no way to move backwards, because time allways goes in one direction. There will never be a time where time goes backwards or in a different direction. Some people believe that going into space for a couple of years is time traveling and in a way they are right because your body feels and reacts to the time it believies it is, while on earth the time feels faster thus ageing the body faster.

This website tells about the theory of relativity and Einstein's theory about space and time. The website was updated recently and gives many examples on how he came up with the theory. It also talks about space and gives informational pictures to help get the idea across. This is a believable site because it is from a popular organization, pbs, and is from a author who has wrote other books on this subject.
