The discussion centers on the source of energy driving the universe's expansion, specifically addressing the concept of "dark energy." Participants emphasize that the expansion is not a result of spontaneous generation but rather a continuation of motion from the original universe. The conversation highlights that there is no limit to this expansion, and speculation without empirical evidence is discouraged. The consensus is that understanding dark energy is crucial for further advancements in cosmology.

phinds said:The expansion is just leftover motion from the original universe I think you are talking about the ACCELERATION of the expansion. The source for that is what we call "dark energy" and if you figure out what that is, I guarantee you a Nobel prize. There is no limit.
As @phinds has said, all of this is personal speculation, which is off limits here. Your title question has been answered.lordoftheselands said:I think that energy would be demanded to make the universe expand even in constant motion, since I imagine space as something attached as glue to the other parts of space. I imagine that there is a counter-force that makes all parts of space stick together.
