I wonder if anyone has ever done the math on how much (in L or kg) water is moved by the moon each day. It's got to be something absurd.

Just wanted to mention I see your pfp on every post.

Thank you for keeping lemmy alive and making like 4% of the total posts. Seeing you post brightens up my day.

No homo.

Let's hope Lemmy grows big enough that I can just be part of the crowd.

I have to assume it's about one moon's worth, divided by the distance squared.

That would be its total pull, not just the water.

We probably can estimate the amount of water that's at a different level from what a moonless Earth would.

We could also say that technically all water is moved somewhat, because gravity is like that.
