How can the universe be expanding faster than the speed of light?
Is expansion of universe faster than the speed of light?
Why is the speed of light so small relative to the size of the universe? Why is the speed of light not infinite? 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 does light travel so fast in space? Will the speed of light ever change? Can we increase the speed of light in a vacuum? Is the speed of the amplitude of light faster than light? Has the speed of light changed? At the boundary of a black hole, does time become so slow that light from it never escapes, or space becomes so large that despite the speed of light being the same, light is not able to escape? How vast is the universe? If the speed of light in a vacuum was doubled, what effects would that have on the universe? Does light travel through space forever? When will we be able to travel at the speed of light? Is there anything bigger than the universe? How we can increase the speed of light? Why did Einstein assume that the maximum possible speed is the speed of light? What’s the speed of light?
