No, I don't have to believe it; I know they do. That can be demonstrated on demand. It's observable and demonstrable. There is also a strong and conclusive indirect evidence for them.
Unlike religion, which relies on miracles, science works on demand, because it is a working model, not a hopeful model.
“No, I don’t have to believe it; I know they do.”
You see what shallow knowledge does? Any half witted high school physics teacher could explain that electrons DO NOT “orbit” atoms at all and the tidy little picture of moon like things going around an atom is a useful way of thinking about them but is manifestly not so.
So what you think you know just isn’t so, it’s a convention used to simplify reality since an “orbit” is just an area where an electron has a mathematical probability of being found.
Is it then wrong to say electrons “orbit” an atom? Of course not if one keeps in mind what is really being said.
Four pillars supporting the earth? Orbits? Six of one, half dozen of the other.
