My Physics Professor from my Physics 1 class says Newtons laws are wrong? Don't get me wrong, but he is a amazing physics professor! One that does not talk to you as if you are dumb or as if he is better than anyone! I love physics and I'm hoping to go into physics engineering, but that's not important. He explains how einstein's theory of relativity 'proves' newtons laws to be wrong. But I've read about this and I've heard that Newtons laws were incomplete. There is a big difference between being wrong and being incomplete. For example, he explains that the closer one gets to the speed of light the object's mass increases which increases affects the Newtons equation F=ma. Which makes sense, I know the basics of Special Relativity very well. But he then explains that this "proves" that Newtons laws are wrong and then he went and said something about how quantum mechanics also proves Newtons laws wrong? I'm pretty sure he only knows classical physics. The reason why is because quantum mechanics and general relativity is need when distances are small and the mass is huge. Which Quantum gravity will solve most of the mysteries of black holes and possibly how particles interact at the subatomic level when the mass is great and distance is small. He said that at low velocity's newtons laws work, but close to the speed of light the answers are wrong because of the effects of quantum mechanic and Special Relativity. This makes NO sense to me and I think he's wrong. But is he right to say Newtons laws are wrong or am I right to say Newtons laws are incomplete?
