If the universe is expanding does it mean matter is also expanding?
If the universe is expanding then does matter also expand?
What will happen if the universe stopped expanding? How is the expansion of the universe explained? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? Is there a limit for 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? How does the expansion of the universe create new space-time? Why does dark energy expand universe? Does space expands faster than speed of light? 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 there anything bigger than the universe? How does the Theory of relativity explain 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? 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? Where does the energy from photons affected by the expansion of the universe go? Is the expansion of the internet much like the expansion of the universe? If you were at the expanding edge of the universe, and observing the expansion, what would you see? If the Universe stops expanding, would that mean that dark energy became 0 or more (infinite) of it could still be created? 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? Why does the entropy keep growing when the universe is shrinking? Is the expansion of the Internet comparable to the expansion of the universe? If the universe starts shrinking, would the time go backwards or would it just be the same? Can another Big Bang happen more than once in our Universe? Is it true that space isn't expanding, and that that doesn't make any sense? How can we calculate the expanding rate of the universe if it has no center? If space expands, it releases stored up gravitational potential energy, which converts into the intrinsic energy that fills the newly created volume? If energy can't be created or destroyed, how can dark energy increase with the expansion of the universe? As ALL matter is created soon after the Big Bang, and in a relatively small area, why doesn't it collapse into a black hole under its own gravitation? If mass is energy and vice versa, can you compact energy into matter? What effects could that have on surrounding environment? Does size of matter affect gravity? Is it the Big Ongoing, not the Big Bang?
