Maybe the idea is that the universe is crammed with a network of... something. Something that science doesn’t know about and whose interactions with physical objects that science does know about does not have to conform to the known behavior of these physical objects. It wouldn’t be quite an “ether.” It wouldn’t need to be “supernatural” in the literal sense, but might be difficult to distinguish from such an entity.
I hope that in my lifetime, someone comes up with an adequate explanation of gravity, and how particles interact to create gravity. All this speculation from "scientists" reminds me of what I've read about people speculating hundreds of years ago about why the night sky revolved about the Earth.
They came up with numerous explanations and formulas, none of which were adequate. Duh! The night sky does not revolve around the Earth! The human race is not yet smart enough to create the right question in order to seek a correct answer about gravity.
Perhaps in close proximity, the objects expel some unseen and unknown antimatter in an opposite direction that then propels them towards each other. In other words, what I'm proposing is that gravity doesn't suck, but that it blows - the smaller mass is "blown" at a quicker rate towards the larger mass. If this is revealed to be true someday, remember that you first read it here on FR!
