So electrons were suppose to crash on nucleus according to classical physics. I want to understand the dynamics of it. The basic idea is that it will slow down as it emit photons. But with what force and mechanism? I think the answer is related with Abraham-Lorentz force, but i see too many contradictions about it. https://www.physicsforums.com/threads/contradiction-in-abraham-lorentz-force.786378/ I would really appreciate if someone can convince me classical physics is really flawed.
