Is Time Emerging? Physicists' Experiments & Many-Worlds Interpretation

[TheQuestionGuy14]

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.

The research is legitimate enough to have been published in Phys. Rev. A:
E. Moreva et al., Time from quantum entanglement: An experimental illustration, Phys. Rev. A 89, 052122 (2014). Preprint.

It appears to our own @Demystifier has cited this paper in one of his articles (to which I unfortunately don't have access).

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].)

Sean Carroll can say anything he wants, because he expects us in this forum to clean up his mess:
