#3An alternative to the “ball on rubber sheet” model of gravity is “twisting a lump out of a sheet of silly putty.” You get the same curvature without relying on gravity to serve as a model of gravity (which always bothered me a bit)
For clarity, here’s what I mean: if you flatten out some silly putty (or pizza dough should work) then pinch and twist together some of the sheet into a lump, that pulls along the surrounding putty. So, if you drew lines on the putty then pulled it into lumps, you’d see the distortion to the lines.

#4Physicists didnt abandon this idea, Wheeler's geometrodynamics was all about the concept of geometry being relevant for more than grabity.
As it happens with so many cool ideas it did not germinate something useful.

Grabity is such an apt typo for gravity

#6If mass/energy were interconvertible with space, if the former were some curled form of the latter, could you explain dark energy as the uncurling of mass/energy into ordinary space?

And your comment is a perfect demonstration of the fragility of the universe: what if the OP edits and corrects their typo?

#8> Einstein finished his masterwork, the theory of general relativity, in 1915. He was 37 years old
Interestingly if you look at the most popular programming languages they were created by someone 37.5 years old, on average [0].

That's a pretty clever model. Do you know any videos demonstrating it?

The recursive model always bothered me too. That’s nice, though harder to explain in words.
