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.

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

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

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

The very last words of the article are

> Time is something the universe continuously writes into itself.

So the next question is "how?"

We can generate interactions by bringing stuff close together, but the definition of closeness is not the naive one because entangled particles are close even if they are millions of miles away.

Knowing the how could spare us the hassle of generating gravity by bringing stuff together and maybe even creating antigravity by unwriting those recorded interactions.

But first, experiments experiments and experiments.
