Since in our world on the exception of light nothing moves at that speed, so what is the use of Relativity ?

Question

Why not just stick to newtons laws?

Answer 1

The theory of relativity is being used in Fermi lab, U.S. to "create" either energy or new matter from energy. Newton's laws only define motion, but they do not explain why some of the mysteries of the solar sytem or the universe occur. With Einstein's theory, however, these mysteries become clearer. We understand more why they occur this way and can predict how much energy is being "created" by calculating for how much matter is "lost." Fermi lab is working to create anti-matter, combine it with matter to create energy, and utilizing the energy into more matter -- it's one of their big projects. I'm sure they're testing for more than that, but it's the overview of what they are doing.

Answer 2

Do not get hung up on the speed of light theory! Where we are now, with our technology, Speed of light is a stopper!

But then, we don't really know anything! What is out there, how vast, why, which plane are we on!

Any life form, transversing the universes, in meaningful time, have to be moving faster than light!

We are so backwards, that we still war with each other! We get here thru union with the male and female, and we are doing our best to F*C& that up! We are gadly spending Trillions to figure out faster ways to kill each other and cry if we are forced to give a dime to help- feed each other.

It is better for the universes that we cannot travel, even better that we believe that the speed of light is a barrier!

Answer 3

It is just this type of theoretical research that gives us solid state electronics, nuclear energy, and a much more optimistic outlook on solving future problems which might plague our small planet.
Who can guess what other scientific marvels will come from our investigations into the workings of the universe.
