Has the total mass and energy of the universe remained the same since the Big Bang?
Since the Big Bang, has the amount of mass in the universe been increasing? Is the amount of energy in the universe decreasing?
Energy cannot be created nor destroyed. How is that possible when the universe is expanding? Scientists are saying that our universe is expanding with increasing speed, from where this energy is coming? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? What if the universe isn't expanding but matter is all shrinking? Is the universe shrinking and stretching rather than expanding? How is the mass of the universe calculated? If the universe is expanding does it mean matter is also expanding? If the universe is expanding then does matter also expand? Is it the Big Ongoing, not the Big Bang? Does dark energy make the Big Bang superfluous? Does dark energy make the Big Bang incorrect? Can we calculate the mass of the universe? As energy can neither be created nor be destroyed, then from where does the universe get energy to expand? Could there be a size limit to the universe's expansion? If the universe is expanding when will it exceed the speed of light? If universe is expanding without a limit and dark and vacuum energy are created as it expands? Is there a limit for the expansion of the Universe? How is the expansion of the universe explained? What will happen if the universe stopped expanding? Why is dark energy the leading theory for why the universe is expanding? Is the universe expanding more than the speed of light? If yes then doesn't it break the cosmic limit? What is the size of the universe? What will happen when the universe stops expanding? Were space time and dimensions created by energy at the big bang? Can energy create all and nonexistent things (e.g other universes…)? Does the universe have a limit to its expansion? What are the proofs of scientists that the universe is expanding? If the universe is expanding then is it possible to calculate the rate at which it is expanding? Why does the entropy keep growing when the universe is shrinking? If universe is expanding without a limit and dark and vacuum energy are created as it expands…? If the Universe stops expanding, would that mean that dark energy became 0 or more (infinite) of it could still be created? If energy can't be created or destroyed, how can dark energy increase with the expansion of the universe?
