If universe expands without limit is there infinite potential energy that transforms into kinetic energy (of expansion) all the time?
I have a question about the universe. If the universe expands without limit, is there infinite potential energy that transforms into kinetic energy of expansion all the time?
That's an interesting question. According to some theories, in an expanding universe, the total energy is conserved but the density of energy decreases as space expands. So the potential energy does not necessarily become kinetic energy of expansion all the time.
