Why is the universe infinite?
Is it possible that the universe will end one day?
According to current scientific understanding, the universe will continue to expand indefinitely, but there is no consensus on what will happen in the distant future. Some theories suggest that as the universe continues to expand, the energy density of empty space will eventually decrease to the point where all matter is torn apart, leading to a "Big Rip." Other theories propose that the universe will eventually collapse in on itself, leading to a "Big Crunch."
