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?
What is the relationship between dark energy and the fate of the universe?
The ultimate fate of the universe depends on the amount and properties of dark energy. If the amount of dark energy remains constant or increases over time, then the universe will continue to expand at an accelerating rate, eventually leading to a "big freeze" scenario where stars and galaxies are so far apart that there is no source of energy left in the universe.
