The discussion revolves around the concept of the universe's expansion and whether there exists an equal and opposite reaction to this phenomenon, exploring theoretical implications and interpretations of physical laws.
Participants generally disagree on the existence of an equal and opposite reaction to the universe's expansion, with multiple competing views presented regarding the nature of dark energy and its implications.
Limitations include the lack of consensus on the interpretation of dark energy and its role in the expansion of the universe, as well as the dependence on specific definitions of action and reaction in this context.

Since there isn't one, this part of your question is not meaningful.if the universe is expanding, what is the equal and opposite reaction to this action?
The expansion of the universe is not that kind of thing, weirdly enough. There are TONS of threads on it here on PF. I suggest you poke around and read some of them, and/or just study the phenomenon online. Although exactly WHAT dark energy is is not well understood, how it works is.Greenlight said:No?
well i guess we could make one up...we can call it dark action. Now my equations work! j/kbut really isn't there dark energy? doesn't energy do work? isn't work action?
