What is the speed at which the universe is expanding?
What is the speed of the universe with which it is expanding?
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? If the universe expanded from the big bang to the size of our galaxy in a micro-second, this must mean everything in creation traveled much much faster than the speed of light; how is this possible? Why is the speed of light so small relative to the size of the universe? 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? Is light speed actually not the speed limit in the universe? How does the Theory of relativity explain the expansion 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? Is the expansion of the internet much like 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? Is the expansion of the Internet comparable to the expansion of the universe? How vast is the universe? How fast is the total movement of the earth due to revolving around the sun, revolving of the galaxy, movements of the galaxy, expansion of space etc? Is anything in the universe faster than light? Will the accelerating space expansion eventually reach lightspeed upon which everything snaps back into singularity and shoots through in another big bang? What is the size of the universe? How fast is Earth revolving around the center of our galaxy? What is the speed of earth? Why is the speed of light not infinite? How is our universe expanding if we are being pulled towards the great attractor? Are we traveling at escape velocity to move away from the GA's pull? Does the universe need energy to expand? Why is [math]c[/math] the speed limit of the universe. It seems so arbitrary. Is there a reason for this? Do galaxies travel faster than the speed of light? What will happen if the universe stopped expanding? If the universe is expanding, why is the Earth moving towards the Sun? Atomic structure, the solar system, the Milky Way are all planar, therefore the universe is planar. Anything in motion has one predominant direction and observations indicate universe to be expanding. Is this expansion more flat in nature? How did Edwin Hubble know the Universe was expanding when we can only detect a small sector of the Universe? Can the speed of light be increased? If the universe starts shrinking, would the time go backwards or would it just be the same? If the speed of light in a vacuum was doubled, what effects would that have on the universe? How fast does the Milky Way move?
