Does the universe have a limit to its expansion?
Does the universe have an edge? Does the universe have a limit to its expansion? If so, what happens when the universe reaches its limit?
If the universe is expanding then where does the extra space come from? Is there space outside this universe? How vast is the universe? Is there anything beyond 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? 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 rate of expansion of the universe increasing? What is beyond the observable universe? Is there anything bigger than the universe? What is the size of the universe? Why is the expansion of the universe accelerating? How was the universe created? Will there be an end to universe? Is it the dark matter that is helping universe to expand? What is the radius of the universe? At the end of the universe, where does everything go? Can we cross the border of our universe? Is the expansion of the internet much like the expansion of the universe? What if the universe isn't expanding but matter is all shrinking? 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? Why is the rate of the expansion of the universe accelerating? What's outside the universe? Is there empty space outside the universe? If the universe is expanding, why is the Earth moving towards the Sun? How does the expansion of the universe create new space-time? Is the big bang even possible? Is the expansion of the Internet comparable to the expansion of the universe? What do you think about expansion of universe or do you really believe in expansion? Since the Big Bang, has the amount of mass in the universe been increasing? Is the amount of energy in the universe decreasing? 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? What exists beyond our universe? Some other universe? How can we calculate the expanding rate of the universe if it has no center?
