Discussion Overview

The discussion explores the relationship between entropy, time, and the expansion of the universe. Participants examine whether the existence of time is contingent upon the universe's expansion and how entropy relates to this concept. The scope includes theoretical considerations and speculative reasoning about the nature of time and entropy in the context of cosmology.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that time is contingent upon the expansion of the universe, proposing that if expansion were to cease, time would also stop.
  • Another participant challenges the connection between time and entropy, asserting that entropy is not a force and questioning the justification for linking them.
  • A different participant agrees that entropy is not a force but argues that it is intrinsically related to the properties of space-time.
  • Another participant states that entropy is a property of matter/energy distributions connected to space-time, but still finds the initial connection unjustified.
  • One participant expresses a belief that entropy is a necessary evil, suggesting that a static universe would be undesirable, and speculates on Einstein's potential views regarding this idea.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between entropy and time, with some proposing a connection while others contest it. There is no consensus on the validity of the claims made regarding entropy's role in relation to time and the universe's expansion.

Contextual Notes

Participants have not fully resolved the assumptions underlying their arguments, particularly regarding the definitions of entropy and its relationship to time and space. The discussion reflects a range of interpretations and speculative ideas without definitive conclusions.

I"m starting to suspect that the existence of time is contingent upon the expansion of the universe. In other words, were the expansion to cease, time itself would come to a halt. As we know, as space accumulates thru expansion, time also accumulates. Thus, the space/time continuum is in fact the force we know as entropy. But were the expansion to stop for some reason, it seems logical to assume that time would also stop.

Thus, in the final analysis, entropy is a necessary evil, since the alternative would be stasis.

Has anyone else come to the same conclusion? Would Einstein agree with this?

You bring up a very interesting connection between time and expansion, they have nothing to do with entropy (as far as I can tell however). More importantly, entropy is definitely not a force.
 
Thanks for you comment. I agree that entropy is not a force. However, i do not believe it is a coincidence that time/space and entropy appeared at the same time.

Entropy, i believe, is an intrinsic property of time space.
 
Entropy is a property of matter/energy distributions, which are innately connected to space-time; I still think you're making an unjustified connection however.

everything and space-time appeared at the same time... so its both not a coincidence for anything, and also not a convincing argument.

Yes. I read someone come up with this idea in a paper I read, but unfortunately I forgot the author.

My guess is that Einstein would not have liked the argument since he seemed to want a static universe. But they again, he was wrong about a lot of things, so what he would have thought of the idea seems rather irrelevant.
