Is our universe expanding?
What are the proofs of scientists that the universe is expanding?
Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? How did Edwin Hubble know the Universe was expanding when we can only detect a small sector of the Universe? How can we calculate the expanding rate of the universe if it has no center? Does the universe need energy to expand? Is the expansion of the internet much like the expansion of the universe? If the universe is expanding much faster than the speed of light, could that be a reason why we don't see much of the universe, only the "new events"? Is the expansion of the Internet comparable to the expansion of the universe? If the universe is expanding then where does the extra space come from? Is there space outside this universe? What will happen if the universe stopped expanding? Since the Big Bang, has the amount of mass in the universe been increasing? Is the amount of energy in the universe decreasing? 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? Our universe is a sphere, but what direction are we expanding in? Are all galaxies moving away from us or are they moving in some specific direction? How vast is the universe? If the universe is expanding, why is the Earth moving towards the Sun? Is there anything bigger than the universe? 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? Where does the energy from photons affected by the expansion of the universe go? Is it the Big Ongoing, not the Big Bang? What is the size of the universe? Why is the Universe the size of what it is? How did scientists calculate the diameter of the universe? If the universe starts shrinking, would the time go backwards or would it just be the same? Why does the entropy keep growing when the universe is shrinking? Is the big bang even possible? Is there positive scientific proof for parallel universes? Do we have any scientific evidence of parrellel universes? Is there anything beyond the universe? Is this universe a experiment by god? Is there any hypothesis that the big bang occurs repeatedly? Is God the universe?
