At what speed is the universe expanding? Is it faster or slower than the speed of light?
How fast do we believe the universe is expanding?
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 the expansion of the internet much like the expansion of the universe? How vast is the universe? What will happen if the universe stopped 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? Is the universe 13.8 thousand million years old or 13.8 million million years? Is the expansion of the Internet comparable to the expansion of the universe? How did Edwin Hubble know the Universe was expanding when we can only detect a small sector of the Universe? Is there anything bigger than the universe? Is it the Big Ongoing, not the Big Bang? If the universe starts shrinking, would the time go backwards or would it just be the same? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? The Universe have a center, and is on expansion. Wouldn't be more precise to say The Universe could be infinite, but at a moment "x" he have an end? Is the big bang even possible? Is the universe 13.75 thousand million years old or is it 13.75 million, million years old? Can another Big Bang happen more than once in our Universe? Is the Big Bang actually possible, or not? How much of the universe has been mapped out? Can we see beyond the event horizon in the universe? What is the size of the universe? Is it possible to create a new universe? Why is space expanding? Can we see the Big Bang? Are we still in the process of the Big Bang. What if only we can experience time at this scale? Will the accelerating space expansion eventually reach lightspeed upon which everything snaps back into singularity and shoots through in another big bang? With this exponential growth of technology, how close are we to traveling outside of the Milky Way? When we look into space, we actually see the past. So, when we say that the universe is about 13.7 billion light years old, does that mean that we can actually look into space up to a distance of 13.7 billion light years? How do we estimate the time since the big bang? Will the universe end in a big freeze? If you were at the expanding edge of the universe, and observing the expansion, what would you see?
