What blows my mind even more, is, contrast to the fact that these tides are from Luna's pull on Earth, which does not move the barycenter outside earth, the effect of Jupiter on Sol, does pull the barycenter outside Sol! Get your head around that, eh!?!!

Some places only get 1 tide a day, some get 2, and some get a weird mix.
Some get 4 high tides in a day. Southampton is weird.
So basically ... like Miller's Planet?
Well it's not near the surface but rather far away in comparison. But also really big a moon.
At some point I saw a yt science video saying that the water isn't moving but the dirt bit is the bit moving during tides
and i don't understand why the tides on the Right Hand coast are like clockwork and the Left Hand side of the country the tides are like "what time is it IDGF HIGHTIDE"
found it "rotating through the tides"
What he's saying is there is always a bulge of water pointing at the moon (and another pointing away from it) the earth spins so the land sees the bulge coming and retreating as our bit of coast passes under the moon
It's a bad description because the water also spins with the rest of the world, so though there always is a bulge that is stationary relative to the moon, there is always different water being part of it.

The tides are also likely responsible for advanced life on this planet. So there is that.
This NASA page has some really cool simple visualizations of how tides work. They are kind of strange in ways you don't expect.

Now think about pouring a bucket of water out on a table. It’s easier to slide the water around on the table rather than lift it directly upwards. When the Moon’s gravity pulls at Earth, the water doesn’t float outward, it just gets pushed and squeezed around on the globe, directed by both gravitational pull and other forces, until it ultimately ends up bulging out on the side closest to the Moon and the side farthest away.
I don't know how to upload gifs to lemmy but check them out on the NASA page they are very satisfying and cool and explain the science wonderfully!

I always wondered how quickly the tides actually change. If the moon is directly overhead, does the tides at the lowest or the highest? Or does it just pushes things around and it's just different?
Think about the moon like a flashlight beam. Where the center hits the ocean, it keeps a consistent pull upwards, and moves the bulge of water as it orbits. Towards the edges of focus, it's dropping a bit of water and it's rippling away as it falls. I am no scientist, but I liked this explanation when I saw it because it was simpler to understand.

I've always thought this about Opal stone. It looks like a made up stone from an alien planet.
