Since the speed the universe is expanding is increasing what will happen when we reach the speed of light?
If the universe is expanding when will it exceed the speed of light?
We all knows that universe is expanding. Suppose that there are two different galaxies travelling in the opposite direction from each other at the speed of light. Can one will be able to see the other one ever? Scientists say that the universe is expanding, and all the galaxies are moving away from one another. How can they be sure that this is due to expansion and not shrinking of all the matter everywhere in the same ratio? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? Is it possible to move at 98% the speed of light, then have the entire universe move the other direction at 5% the speed of light? If the universe starts shrinking, would the time go backwards or would it just be the same? Assuming the Many Worlds theory is correct, is there a universe in which the speed of light is different than our own? How would that change things? Will the accelerating space expansion eventually reach lightspeed upon which everything snaps back into singularity and shoots through in another big bang? Why is the speed of light so small relative to the size of the universe? Does the universe need energy to expand? How does the Theory of relativity explain the expansion of the universe? Is the universe infinitely large? Is light speed actually not the speed limit in the universe? Since the Big Bang, has the amount of mass in the universe been increasing? Is the amount of energy in the universe decreasing? How vast is the universe? If the speed of light in a vacuum was doubled, what effects would that have on the universe? Where does the energy from photons affected by the expansion of the universe go? Is there an end to the universe, and if not, is the universe infinite? Would we get more dark energy as the universe expands? Why is dark energy the leading theory for why the universe is expanding? Can we increase the speed of light in a vacuum? Is it possible to increase or decrease the speed of light? Is the Universe infinite or is there an end to the Universe? Why is the speed of light not infinite? If everything came from one point, at the Big Bang, and nothing can move faster than the speed of light, how can something be outside the observable Universe? Can we see beyond the event horizon in the universe? Since light doesn't have rest mass but has energy, so if huge amount of light is accumulated at a point in space, will it warp space-time? Is the expansion of the Internet comparable to the expansion of the universe? Does light travel indefinitely in space? If a photon travels at the speed of light and time dilation at the speed of light is infinite, does this mean that, from the photon's perspective, it takes no time at all to cross the entire universe? Is there anything bigger than the universe?
