How fast is universe expanding compared to light speed?
How can the universe be expanding faster than 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? 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? 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? 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?
