Yes, everyone knows that.
But how does that really work…?
Is it a giant coincidence?
surely not

so what quality of the 2 bodies or of the solar system makes those 2 periods coordinate in that way

something to do with the ratio of the weights, speeds and distances

does Newton explain it?
or GR?

No

Yes

Google ‘tidal locking’. Whether it’s easily understandable is a separate question, but the Physics has been well understood for a long time - no need for any pesky 20th century quantum or relativistic malarkey.

So what proportion of moons do that?

Given enough time and the right conditions, erm… all of them.

Do they have to listen to Tidal on the moon?

All day, as they rotate at exactly the equivalent rate to Gaia?

It’s not the maths or the theory that does my head in, it’s that when I visualise the Earth turning on it’s axis and I visualise the moon turning on it’s axis too, at exactly the right rate to make it match and face the earth for billions of years of days…it seems quite like spooky action at a distance.

But then the fact that when a lump of ice melts, it doesn’t overflow the glass of water, nor does it allow the meniscus to drop below the glass rim - that too is pretty amazing.

But surely you didn’t hope to explain a macro phenomenon using quantum aleatory stats…

Sorry for total thread drift
Am giving up the booze for jan so had to finish the bottle

It is action at a distance, but nothing spooky about it. Just gravity.

yes, in the end no more amazing than that a dog can catch a ball in mid air.
(except the dog is alive…)

Takes the average dog a bit of practice. Not sure about the Moon :sunglasses:

Just for fun, I have a counterclockwise clock. But considering from a North Pole perspective the Earth and moon rotate counterclockwise, it should be more logical.

I’d be fascinated to know what a non-subjective listener was - given that listening implies a consciousness and hence precludes objectivity…
