I enjoy building up speculative ideas and knocking them down again. I find that I often do learn a bit in the process.
I wrote this about six months ago, as an attempt to make a mental picture of how gravity could work. Then I found a flaw that killed it, so I left it at that. Now, I read it again, and can't remember what knocked it on the head, for me. I think it was something to do with gravitational time dilation, but can't remember what. And it turns out I had the wrong idea about that
