What is the speed at which the universe is expanding?
At what speed is the universe expanding? Is it faster or slower than the speed of light?
Is light speed actually not the speed limit in 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? 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? Do galaxies travel faster than the speed of light? If space can expand faster than speed of light, then could a gravity wave travel faster than the speed of light as it's a ripple in space? 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 the speed of light be increased? Is it true that Matter waves are faster than the speed of light? How does the Theory of relativity explain the expansion of the universe? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? Why is the speed of light not infinite? How vast is the universe? Is there anything bigger than the universe? What make galaxies to Travel Faster than speed of light? Is the speed of dark faster than the speed of light? Is the expansion of the internet much like the expansion of the universe? Is the expansion of the Internet comparable to the expansion of the universe? If the universe starts shrinking, would the time go backwards or would it just be the same? Do gravitational waves travel faster than the speed of light? Will the speed of light ever change? Will the accelerating space expansion eventually reach lightspeed upon which everything snaps back into singularity and shoots through in another big bang? Has the speed of light changed? Is space time infinite? Why does light travel so fast in space? Is faster than light travel possible? Is the speed of the amplitude of light faster than light? If everything came from one point, at the Big Bang, and nothing can move faster than the speed of light, how can something be outside the observable Universe? Can we increase the speed of light in a vacuum? What can travel faster than the speed of light?
