Question:
What is rotation that it is found everywhere at all size scales in the universe? It exists in spin in fundamental particles, as rotation of planets about suns, of suns in galaxies, of galaxies in clusters, etc.

The person who asked me this question said they had tried to deal with things like conservation of angular momentum, but that doesn't really say why rotation itself is such a common thing at all scales of physical reality. Can you help?

Replies:
If you want to live in a three-dimensional space, there are some things you're just going to have to put up with.
