At what speed is the universe expanding? Is it faster or slower than the speed of light?
How can the far reaches of the unobservable universe be expanding at 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 so small relative to the size of the universe? 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? Will the accelerating space expansion eventually reach lightspeed upon which everything snaps back into singularity and shoots through in another big bang? How vast is the universe? Is light speed actually not the speed limit in the universe? Is faster than light travel possible? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? Can the speed of light be increased? Why does light travel so fast in space? Why is the speed of light not infinite? Can we exceed speed of light practically? Could we ever reach the non-observable universe using time dilation in the same way we could reach Andromeda? Do gravitational waves travel faster than the speed of 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? Is there anything bigger than the universe? Can there be a particle faster than light? Since information cannot be transported faster then the speed of light, isn't Einstein's "spooky action at a distance" solution more correct then "quantum entanglement"? Could there exist an Universe, parallel to ours, where the light velocity be greater than in ours, which interacts with our Universe in a subtle way? How fast can you accelerate to the speed of light? 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? Can a black hole accelerate an object beyond the speed of light by its attraction? How far can sunlight travel in space? Is it possible that massive objects such as stars can make time go slower around them? If yes, then how ?? How does the Theory of relativity explain the expansion of the universe? Can we increase the speed of light in a vacuum? Will the speed of light ever change? Can you exceed the speed of light? Can data travel faster than the speed of light? Is space time infinite?
