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 would be the implications of dark energy becoming negative?
That's a very interesting question, but it's important to emphasize that this is still a speculative idea that has not yet been confirmed by observations. However, some theories suggest that if dark energy becomes negative, it could actually cause the universe to collapse in on itself, leading to a "big crunch" scenario. But at this point, it's still very much an open question and an area of active research.
