I'm not certain gravity has ever been completely explained. The guy that built coral castle (leerskillen or something like that) said gravity as we know it doesn't exist, he put it down to the fact that every object has a magnetic pull, that's how he claimed he built his castle and how the pyramids were built. It's sketchy but I thought I'd put it out there.

Personally I think science lost its way after Newton when it went truly materialistic. I think 'invisible forces', earth energy, magnetism, electromagnetism, frequency etc.. Could answer a lot of scientific mysteries better than modern science. I did a degree in science and science was my god for many years. I've now lost faith in it completely, there's so much we don't know, misunderstand or have been sold false solutions to that I think many things will go unanswered.

The ancients had the answers, we don't, why would that be?
