Is it just me who found the technical description and analogy here lacking? There's nothing that suggests electrons are a cloud. Yes, a "cloud" defines the probability where they can be found, but electron doesn't occupy the cloud. Electron is always a point, no matter what wave function it has. Therefore, from this perspective space is all empty. If you invoke path integrals and infinitely many things bubbling in an…

Some think that electron is a string!
“Empty space” is a completely relative notion. If I have a heavy steel safe which I do not have the key for, whether there is an empty space inside it is irrelevant, and the space occupied by the safe cannot be seen as being (partially) empty in any practical sense.
> Inside your body, you aren’t mostly empty space. You’re mostly a series of electron clouds, all bound together by the quantum rules that govern the entire Universe. So we are mostly electron clouds... and clouds by definition are mostly empty space.

But empty space isn't .. er .. empty ...
How often do objects interact with our bodies when passing through us? Neutrinos, very rarely. The atoms of an aluminum bat, very commonly. Light? It depends. Something being "empty" or "full" all depends on spatial and energetic scale.
Yeah, the fact that neutrinos pass through us largely validates the notion that we are in fact mostly empty space.
What is it about Medium that produces less than stellar articles? Because it is a paid blogging service so people just blow out some smoke and hope to make a little money?
