From what I understand, the closer you get to the speed of light, the slower time moves. So theoretically, could our world have been created in the "six days" as purported in the Bible? Of course the sun hadn't been created till day 4, so I realize the inherent problem--but if they were indeed 'earth days'--with the relativity of time taken into consideration--is it possible if the observer were moving at the speed of light?

Is saying we can never travel faster than the speed of light the same as saying we would never go faster than sound? Seems to me that this is a barrier that exists for the sole purpose of existing and until someone disproves Einstein it will continue to exist.

I am aware of the usual three dimensions for space and a fourth demension for time, however on watching a program on wormholes, the announcer mentioned there could be 122 or more demensions. I wonder what would the parameters of these demensions be?. Can they be explained in our 4D universe???What bounds would they have? or is it all another "epicycle" like explanation.
Thanks

We are told that before the big bang, laws of physics as we know them today did not exist. No dimension or time. This being the case the bang itself was a change of state, so time must have been or the bang could not start? Please explain.

why is the universe not bright?
why is the universe so cold?
where does the energy of heat and light go?
