Is it possible that that there is a second time dimension which we might access under special circumstances?

Question

Thanks to unlv_engineer, I have more detail to add in retrospect...... The assumption that light travels at a constant speed has already been dealt with by physicists at Berk 4 years ago.... so it isn't a constant (mathm. alright so it is... but question).... the potential secondary time dimension may or may not be the sole time dimension (we understand that at this point there is only one)....what is the physical likelihood of crossing into and out of that dimension riding on a cosmic ripple in space as propoed by Susskind's Cosmic Landscape?

Answer 1

If superstring theory is correct and really needs 10 or more dimensions, then it would'nt surprise me if at least one more in the pile was temporal. If I had to bet, I'd bet against it.

Answer 2

Hi,

Some say that there are infinitely many dimentions that we move through as we make each little decision every day. That we are in this dimension is not unique, and we are acting out all possibilities at all times, and this one is just the one that you happen to be experiencing.

I don't happen to believe that one, because I think it means that we would all have to be on the same path, and it seems like we can't all get on the same path about anything else, so why would we be able to do it with that?

That probably doesn't help, but guessing from your screenname, you're used to difficult questions with confusing answers.

Actually time is not constant - light is... As per The Funny Hair Dude.

Have you noticed, a fly is much smaller than us and cannot move the same distance as we can in the same time - but you still have a heck of a time swatting one.

That's because of perspective. Time changes due to one's scale.
