Why doesn’t the Electron crash into the proton?? We know in an H atom the e- is attracted to the + charge of the proton. And it wants to get down to the "0 level" orbit. But what makes that level zero – or why does e- stop going down? Is there another force that counteracts the force of charge trying to pull them together? Note: the intent of this thread is potential descriptions of why the electron does not crash into a proton. NOT how QM defines it or that QM can claim that no one can describe it. But how people do try to describe it. So explaining why an idea doesn't work should also be described in Non-QM terms. Everybody already knows that uncertainty and the math of QM does work, we do not need to be reminded.
