Time travel

[kandrathe]

My 2 cents. First to rehash a little. Time is an artificial construct which we use to describe the phenomena of observed motion. We live in a multi dimensional continuum of quantum soup. We are merely a chunky part of that soup, a semi-solid which loosely holds itself together within a gaseous cloud. We like to think of ourselves as a particle that can be described mathematically by XYZ spacial dimensions and a constant linear time dimension. But that may just be our experiential bias. From Einstein's special relativity we know that this soups time space is radically altered by velocity, and mass. I feel the secret is held in a deep understanding of gravity.

We experience time travel already. If one were to have two perfectly syncronized clocks and put one in a space ship and fly it very fast, at nearly the speed of light for awhile then return it to earth the times would be different. We can already explain that kind of time displacement with special relativity. But, further work by Einstein and other physicists showed there to be some inadequacy to his theory.

Einstein was set on the idea that the answer was elegant and I have to agree. There will be no divide by zero error in time travel equations, hence no paradoxs. I think the idea of parallel universes is just another "construct" of our imagination which allows us to figure out a way it could work. So, thinking back to continuum, it is doubtful there is anything like discrete parallel universes.
