How can the far reaches of the unobservable universe be expanding at 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? Can the speed of light be increased? 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? Do gravitational waves travel faster than the speed of light? Will the speed of light ever change? Can we increase the speed of light in a vacuum? How does the Theory of relativity explain the expansion of the universe? Is the speed of the amplitude of light faster than light? What happens if you travel faster than the speed of light? Could the speed of light be increasing/decreasing? Can some particles travel faster than the speed of light? Has the speed of light changed? 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? 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? What is the particle faster than light and why? How fast can you accelerate to the speed of light? 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?
