At what speed is the universe expanding? Is it faster or slower than the speed of light?
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? 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? Since the Big Bang, has the amount of mass in the universe been increasing? Is the amount of energy in the universe decreasing? 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? 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? 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? 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? What is the speed of time? Does the Big Bang infinitely repeat itself? Is space time infinite?
