What is the speed of the universe with which it is expanding?
How can the universe be expanding faster than the speed of light?
Why is the speed of light so small relative to the size of the universe? 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? Is light speed actually not the speed limit in the universe? Why is the speed of light not infinite? How we can increase the speed of light? Can we increase the speed of light in a vacuum? Will the accelerating space expansion eventually reach lightspeed upon which everything snaps back into singularity and shoots through in another big bang? Will the speed of light ever change? Why does light travel so fast in space? Is the speed of dark faster than the speed of light? Is there anything bigger than the universe? Is it possible to increase or decrease the speed of light? What will happen if the universe stopped expanding? If the speed of light in a vacuum was doubled, what effects would that have on the universe? Is the speed of the amplitude of light faster than light? If galaxies are moving further apart at faster speeds could that in fact mean, they are being pulled toward something instead of being pushed away from each other? Since the Big Bang, has the amount of mass in the universe been increasing? Is the amount of energy in the universe decreasing? If the universe starts shrinking, would the time go backwards or would it just be the same?
