Is dark/vacuum energy infinite because the expansion of the universe is infinite and more and more of it is created as the universe expands?
So is dark energy infinite?
It's not entirely clear. One possibility is that dark energy is a constant energy density that remains constant as the universe expands. Another possibility is that the density of dark energy may increase over time as the universe becomes more and more spread out. There are also some speculative ideas that suggest that dark energy might change over time or even become negative at some point in the future.
