If universe is expanding without a limit and dark and vacuum energy are created as it expands…?
Is there anything else you can tell me about the expansion of the universe?
One of the interesting things to note is that as the universe expands, the light from faraway galaxies becomes redshifted, meaning that the wavelength of the light gets longer and the energy of the light decreases. This effect is known as cosmological redshift.
