Opps,this should have gone in the time and space topic. I hope it can be moved. Sorry.
Hope there are some Quantum Physicist guys out there.
Here is a theory I have had for awhile, I need input form an expert to see if it has any merit. From what I know of Quantum Physics and relativity it seems, on the surface, to be a reasonable argument for the universe being eternal (and some other connotations if it is correct)
First some background:
According to the current theories of the physical universe, the future of the universe is that it will end in either the big crunch (like a reversal of the big bang), or heat death (when all the energy created by the big bang runs down).
With the amount of matter known in the universe, the universe should keep expanding to heat death. But more matter is being discovered all the time and most Physicists think that the universe will eventually collapse in a big crunch and be crushed out of existence. Either way the universe ends as nothing or a dark cold universe where their is no more energy to produce suns or light.
Now some relativity:
If we were able to get on a spaceship and accelerate towards the speed of light, the theory of relativity says that time will begin to slow down relative to the folks back on earth. The closer we get to the speed of light the slower the time on our spaceship. Relativity says we cant go the speed of light, but if we were able to, once we were traveling at the speed of light,
time would stand still on our spaceship relative to the time on earth.
Now some perspective:
So, here we are on our spaceship, going toward the speed of light. From our perspective time is not slowing down, everything seems normal to us. From our perspective, the time on earth is
speeding up as we approach the speed of light! So imagine we are watching the folks on earth as we approach the speed of light... they are going faster and faster, like a video on fast forward... still closer to the speed of light, those folks are going so fast they just look like a blur. At very nearly the speed of light we cant even see them through our telescope, they are going so fast.
Now here's the clincher:
Once our spaceship reaches the speed of light, what happens to the folks back on earth? They have been going faster and faster as we approached the speed of light, and if they could see us we would be moving about slower and slower, until at the speed of light, we are frozen as time stands still. But, the folks on earth, well, how can I break the news. According to us, all time that ever was has already happened on earth! Its all over and done! relative to us, time on earth went so fast that at the time we reached the speed of light, time went so fast on earth it became infinite. That means it all happened at once. Sooooo.... that means, if the universe ENDS in a big crunch or heat death, that would have happened, relative to us.
Here is the theory:
We cant go the speed of light, BUT... photons go the speed of light all the time. Sooooo.... relative to us, time on a photon stands still, and relative to a photon.... speeding around at the speed of light... time on earth and the universe is infinite... which means relative to a photon, the big crunch or heat death have already happened.... BUT, that would mean photons could not exist! If the universe has ended in a big crunch or heat death, that means no more energy, no more light, no more photons. But still they exist! So this must mean that the universe doesn't end in heat death or the big crunch. The universe must be eternal.
Or an I missing something??
