Discussion Overview

The discussion centers around the concept of time as an emerging phenomenon, particularly in relation to quantum entanglement and the many-worlds interpretation of quantum mechanics. Participants explore the implications of recent experiments and theoretical perspectives on the nature of time and spacetime.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose that time is an emerging phenomenon from quantum entanglement, suggesting that time may be static for an outside observer while flowing for inside observers.
  • Others argue against the notion of an "outside observer," claiming that this concept does not make sense in the context of the discussion.
  • One participant cites a published paper in Phys. Rev. A that discusses time emerging from quantum entanglement, indicating that the research is considered legitimate.
  • There is mention of Sean Carroll's views on spacetime being emergent, with some participants noting that these ideas are speculative.
  • A participant expresses skepticism about the clarity of Carroll's arguments, suggesting that the forum is expected to address the complexities of his claims.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the validity of the concept of an outside observer and the implications of the experiments discussed. There is no consensus on the nature of time or the interpretations of the experiments.

Contextual Notes

Some claims rely on specific interpretations of quantum mechanics and the nature of observation, which may not be universally accepted. The discussion includes references to various papers and theoretical perspectives that are not fully explored within the thread.

Who May Find This Useful

Readers interested in the philosophical implications of quantum mechanics, the nature of time, and emerging theories in physics may find this discussion relevant.

I saw a post recently which said that time is an emerging phenomenon from quantum entanglement, physicists conducted an experiment which shows that time is static for an outside observer of the universe and only flows due to entanglement for inside observers. Does this imply that if entanglement didn't exist, time wouldn't? However, physicist Ron Maimon stated that this experiment is "It's press nonsense. It's "quantum collapse" and "measurement" emerging from entanglement, i.e. many-worlds interpretation"

Sean Carroll has a post which talks of spacetime being emerging too.

I think that automatically doesn't make any sense since there IS no such thing as "an outside observer".

Sean Carroll has a post which talks of spacetime being emerging too.
Which, as he states, is entirely speculative.

has cited this paper in one of his articles (to which I unfortunately don't have access).
It's on Arxiv but it's just mentioned in passing.
(For related approaches, not directly referring to many worlds, see also [45, 46, 47, 48].)
