One-electron universe

The one-electron universe is an idea proposed by scientist Erwin Schrodinger in 1926. It's a thought experiment that suggests the entire universe could be made up of just one electron. The thought experiment suggests that the entire universe, all the stars, planets, and galaxies, are actually features of this single electron. The idea is that the electron is in an incredibly high energy state, so it is vibrating and spinning in a way that creates the appearance of all the other things in the universe. It's a bit like if you had a little rubber ball bouncing all over the room, and depending on how it bounced it could look like a chair or a desk or a lamp - even though it was just one ball. It's a way of thinking about the universe that helps scientists better understand quantum physics.
