This is just a thought. I was thinking about how quantum theory started to arise, with Planck and assuming energy that the electron's energy around the nucleus is quantized,ect. I started to think of the electron like a sea of water molecules, where there is a required energy to go from one phase to another(liquid to gas for example), and that if you do not give it that required energy it will not switch phases. Obviously this is just figurative, I am not supposing that electrons are made of water molecules, I'm just wondering that it could maybe work similar to that. Sorry, if my writing was very shaky and hard to follow, because the idea is just in a nascent stage. I'm not trying to disprove QM or anything. The thing I am talking about also might have something to do with string theory possibly, but I'm really not sure. Feel free to comment, because I want something to start with if I decide to look deeper into it. Thanks all, I'm sure you'll tear my idea into bits but that is ok!
