However water goes down the Antipodean plughole in the opposite direction to here in Europe. That is caused by the Earth's rotation - just as cyclones and anticyclones rotate in opposite directions. In this case the macro matches the micro - but not with the gravitational pull of the moon.

If you really wanted to look for a potential factor it would be cosmic particles. They are passing right through us all day and all night, passing through the latticework of atoms like tennis balls thrown through scaffolding. They do, very occasionally, hit the structure.

We know roughly how often they hit Earth (and thus us), but we don't know exactly where they come from. There are lots of sources. All active stellar bodies emit them. But trackng any particular cosmic particle back to its source is impossible AFAIK.

You can't be me, I'm taken
