Sorry for late reply, needed some sleep and am reading that link now. I largely agree here.
Yes, LET comes to mind, Lorentz Ether Theory.
I always look for a physical system, else I cannot understand what is going on. So in those days, with my very simple computer (what was it? Z80 system I designed), I wrote a simulation for a number of bodies and Le Sage like particles, just to see if the results were anything like what you have with gravity. Le Sage proposed many particles traveling at high speed in all directions, where you get some 'shadowing' by say planets etc and a resulting force. The simulation I wrote worked! Now that was at least some mechanism, question then arises: Where do those particles come from?' and 'are those the same all over the known universe, or are there places where those particles are less frequent, have less density, and what would (if those particles are of subatomic size) look atoms like if that compressing force _and here we go_ was not present?.' Larger atoms (pendulum) slower clocks in Le Sage shadowed areas, clocks run slower in those shadowed areas near earth? Not saying that idea is correct, but .. some tests have shown that gravity has the same speed as light, could a LS particle be the medium, the ocean that light waves propagate in? Now I have connected gravity and the other forces, where Einstein failed. Again, these have been my thoughts in those years, think I mentioned that several times in newsgroups. And then there is the mathematical stuff. Indeed electricity without electrons makes little sense, that broke down with the Fleming experiment a current in vacuum (in a vacuum tube). Electrons We really need a mechanism. We are rather big, and can only see so far into the ever smaller world, we now know about atoms and other elementary particles, but what if you go smaller and smaller...
It could well be if the previous holds true, that much of todays (2019) physics about what the universe is, big bang, is completely wrong.
