If the universe is "expanding", is my room expanding? Are atoms expanding? Is everything expanding?
If the universe is expanding does it mean matter is also expanding?
How is the expansion of the universe explained? What will happen if the universe stopped expanding? Does the universe need energy to expand? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? What do you think about expansion of universe or do you really believe in expansion? Could there be a size limit to the universe's expansion? How did Edwin Hubble know the Universe was expanding when we can only detect a small sector of the Universe? Is there a limit for the expansion of the Universe? Is the expansion of the internet much like the expansion of the universe? 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 does the Theory of relativity explain the expansion of the universe? How does the expansion of the universe create new space-time? 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 it true that space isn't expanding, and that that doesn't make any sense? 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? Is the expansion of the Internet comparable to the expansion of the universe? How can we calculate the expanding rate of the universe if it has no center? Why does dark energy expand universe? Is there anything bigger than the universe? If you were at the expanding edge of the universe, and observing the expansion, what would you see? Does space expands faster than speed of light? 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? If the universe is infinite, and an object in it changes size, its size relative to the universe stays the same. Why isn't everything the same size? As energy can neither be created nor be destroyed, then from where does the universe get energy to expand? If universe stops expanding, would that mean that dark energy became 0 or more (infinite) of it could still be created? Where does the energy from photons affected by the expansion of the universe go? If the Universe stops expanding, would that mean that dark energy became 0 or more (infinite) of it could still be created? 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? Would we get more dark energy as the universe expands?
