So how do I travel backwards in the 4th dimension? Or conversely, where's the source of the force that propels us through the 4th dimension?

I'll leave this comment here since I'm about to get rate limited: I read/heard a great idea recently, what if gravity is an emergent quantity like heat? Maybe dense fermions just radiate gravitons just like a hot mass radiates photons?

Gravity is the result of spacetime curvature, if I remember correctly.


Yes, but it's irreconcilable with quantum mechanics. So what I described was one of many attempts to do so.


In that case, wouldn't it have to be more complex than just a particle which creates gravity? Something which is compatible with the finding of spacetime curvature?
