Still however, even when laws of science and physics have been revised, the old laws they revised still applied. For instance, Newton's Laws of Motion have not yet been repealed even though Einstein discovered Relativity.
We may find that time travel is possible, but it might require conditions that would make it impractical. Similarly, we may find that going faster than the speed of light is possible but again, not practical.
(As an aside, scientists have theorized that there is a family of particles that actually DO go faster than the speed of light.... they are called "tachyons". However, they have never been observed. The strange thing about tachyons is that they can't go SLOWER than the speed of light.... it's because they have "imaginary" mass. "Imaginary" numbers are those numbers that are multiples of the square root of negative one. If you try to take the square root of a negative number on a calculator, you'll get an error. However, imaginary numbers are used quite a bit in theoretical physics.)
So basically we are talking theory and hypotheticals as tachyons have never actually been observed or quantified?
Is there any scientific proof that time travel is doable or is that all conjecture and theory as well. I have heard about the theory of bending time or looping time by going at certain unattainable speeds.
