Your link refers to 'entropic gravity', a theory that I mentioned way, way back on page 17, and which elicited no response whatsoever!
Entropic gravity describes gravity as a force which results from the universe's statistical tendency to increase its entropy.
It's a controversial theory, akin to thermodynamics, that suggests that general relativity is a macro-scale manifestation of quantum level disorder.

At times like these I like to 'Ask Ethan':
https://www.forbes.com/sites/starts...e-universe-have-zero-entropy-at-the-big-bang/
You'll remember from our previous discussions that what is postulated to have existed before the hot Big Bang is "energy inherent to a field or the fabric of space itself, rather than particles, antiparticles or radiation". This energy was released during the period of 'cosmic inflation' that preceded the hot Big Bang.
Ethan's article is pretty heavy reading, but perhaps the following quote may suffice to describe the changing entropy of the universe:
"During inflation, the entropy of our Universe must have been much, much lower [...]. But what’s important is this: the entropy of the Universe doesn’t particularly change all that much; it simply gets diluted. The entropy density changes dramatically, but whatever pre-existing entropy was present in the Universe prior to inflation still remains (and can even increase), but gets stretched across larger and larger volumes."
I think that also that field was brought to the zero point at a (!) bing bang - so actually, at some point the in crunch/bang process, there was literally no-thing at all except for the summit of all energies of all forms at one point. Boom. Big bara boom... 😉

Thermodynamics is, of course, an accepted theory.
What I said was that entropic gravity was "akin" (of similar nature) to thermodynamics.
By that I meant that entropic gravity looks at gravity from a thermodynamic perspective, i.e., that of the micro-scale influencing the macro-scale.
