Sorry guys for not commenting to your posts. I will eventually.
I have another question: If a horse ran 1 mile east, then 1 mile south, then 1 mile west, then 1 mile north, is it changing direction or rotating?
An issue I have with tidal locking is that it requires billions (not thousands or millions) of years to achieve. A lot of things can change in several billion years. If space weather is anything like Earth weather, it can be pretty chaotic and unpredictable. Tidal locking assumes no changes in distribution of mass. If Venus was once a comet entering the solar system as Velikovsky theorizes, wouldn’t it disrupt the formula for tidal locking for the satellites of all the planets? How could they have synchronized so soon after that event?
