Why is the rate of the expansion of the universe accelerating?
Why is the rate of expansion of the universe increasing?
Does the universe have a limit to its expansion? Is there a limit for the expansion 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 the expansion of the internet much like the expansion of the universe? Could there be a size limit to the universe's expansion? Is the expansion of the Internet comparable to the expansion of the universe? What will happen when the universe stops expanding? Does the universe need energy to expand? What if the universe isn't expanding but matter is all shrinking? What will happen if the universe stopped expanding? 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? Does space expands faster than speed of light? How did Edwin Hubble know the Universe was expanding when we can only detect a small sector of the Universe? Where does the energy from photons affected by the expansion of the universe go? Is the universe infinitely large? How can the flow of time be the result of universal expansion when the expansion of space itself seems to depend on the flow of time? 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? If the universe is expanding, is there a centre point which remains fixed? 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? Does the universe evolve? Is it the Big Ongoing, not the Big Bang? What is the size of the universe? 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? How much of the universe has been mapped out? How can we mathematically prove that in a collapsing universe the entropy still increases? 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 starts shrinking, would the time go backwards or would it just be the same? Why is the dollar increasing? How vast is the universe?
