OP here. This is a blog post for a science comedy podcast, so the science is accurate but delivered with about 47% more workplace humour than you'd find in Physical Review Letters.

The core premise is based on real, cutting-edge physics research, though it's still an active area of debate.

The Page-Wootters mechanism (proposed in 1983, experimentally validated by Moreva et al. in 2013-2015) does show that time can emerge from quantum entanglement between subsystems. In their experiments, time exists for observers inside entangled quantum systems but not for external observers viewing the whole system.

The Wheeler-DeWitt equation really does lack a time parameter, creating what physicists call the "Problem of Time" in quantum gravity. And there is genuine convergence across string theory, loop quantum gravity, and causal set theory toward "emergent spacetime" models.

However, this doesn't mean time is "fake", it suggests time might be like temperature, which is real and measurable but emerges from more fundamental processes (molecular motion). The research indicates time could emerge from quantum information rather than being a fundamental dimension.

The 2023-2025 research I mentioned (cosmological time dilation measurements, atomic clock advances) is real, though the interpretation that "consciousness creates time" is more speculative than the underlying quantum mechanics. So yes, "emergent time" is a serious scientific hypothesis with experimental support, but science is still figuring out exactly what that means for our understanding of reality.

you used the word instant quite a bit. and the word moment a few times. notably, to define what an instant is. was there any particular reason you didn't just use the term moment throughout?

Probably subconscious. I tend to use "instant" when trying to sound more technical/physics-y and "moment" when being more conversational. If time is emergent, both words are describing the same phenomenon.

It's like the difference between saying "temporal coordinate" versus "when", one sounds more scientific but they're pointing at the same thing.

This might be a really dumb question, but how do you use "temporal coordinate" in a sentence where you would use "when"? For example: "When I walked my dog ..."? :D

Probably something like "In a strike of great coincidence, we both met because we went walking our dogs at the same temporal coordinate"

Thanks! I will be using it. :D

Are there any more examples besides "when" -> "temporal coordinate"?
