If universe is expanding without a limit and dark and vacuum energy are created as it expands?
Can you tell me about the expansion of the universe and the creation of dark and vacuum energy as it expands?
Sure! The expansion of the universe refers to the increase of distance between galaxies as time passes. Dark energy is a hypothetical form of energy that is thought to permeate all of space and accelerate the expansion of the universe, while vacuum energy is the energy in space that is not associated with any particles.
