Is time a fundamental part of reality? Quiet revolution in physics suggests not

I wonder if since space is being created (expansion) and space is really spacetime then it’s really new spacetime.

so the universe is a revision control system? or only-last-revision system?

Does it mean that an old galaxy will necessarily turn into a black hole due to accumulated interactions in the past?

While I have come across the idea of information-as-entropy and gravity’s role in it, this is the first time I have read anything that stitches time into the equation.

Holy. Shit. This sounds so very compelling.
