The fact the moon always faces us the same way fascinates me. Apparently the explanation is that our tidal bulge, and its tidal bulge "sync", which sorta makes sense. I wanted to know a bit more about this, if you guys dont mind helping a layman understand it all. Do we have evidence of a tidal bulge on the moon? (obviously we have evidence of tidal bulge of the oceans!) There are craters all over the side that faces us (apparently moreso than the "darkside), so presumably its very old, and hasn't always been synced, or was maybe synced in the opposite direction? Do we know how long its been synced this way? How common is this feature of a satellite? Are we aware of any planets that do this with their sun? Or any other moons that do this? Is it statistically rare? Sorry if my questions seem dumb, this stuff seems hard to google without getting either simple explainations, or a whole bunch of wacko stuff. Appreciate the help, cheers!
