The discussion centers around the source of energy for the universe's expansion, exploring concepts related to the nature of this expansion, the role of dark energy, and the limits of expansion. Participants engage in both speculative reasoning and attempts to clarify the underlying physics.
Participants exhibit disagreement regarding the nature of the universe's expansion and the role of dark energy, with some asserting the necessity of energy for expansion while others focus on established scientific concepts. The discussion remains unresolved, with no consensus reached.
Some arguments rely on personal speculation and lack empirical support, which has been pointed out by other participants. The discussion includes unresolved questions about the limits of expansion and the nature of dark energy.
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.
