Einstein's Uncle

Well, Im not gonna disagree with this. I personally think there is something fishy about the third law. Yeah yeah I get it, Im not claiming to be smarter than every physicist in the past few hundred years, Im just saying that I think it is faulty. And yes I know all about Newton's third law. Im not some confused 3rd grader coming this this thread to deny stuff I know nothing about. This isn't a "differential equations are false because they are too hard" kind of thing. Im just saying that there is something logically "weird" about this law. Just thinking about my chair currently pushing me up into the air is really really weird. Now correct me if Im wrong. Force is defined as energy as an attribute of physical interaction. What I dont get is how something that is stationary and has absolutely no energy of any kind (ignore gravitational potential) can suddenly get enough force to push back with an equal force no matter how hard something pushes against it. Is force energy? Because if it is than there is something really wrong going on here. Energy is apparently being created just because it has to be. So... is Law of Conservation of Energy false? Another example. Lets say I try pushing a box that weighs 10 kilograms across a flat friction-less surface. I push with a force of 100 Newtons. The box is apparently pushing back with 100 Newtons. So why the hell doesn't the net force equal zero? Where is the energy that pushes the box coming from? As for the finger bending argument. My finger is bending because it cant pass through molecules and the molecules are resisting being compressed. The third law works if energy comes from outside a closed system. This stops a car from driving forward if you push forward against it while inside. So that brings me to the EmDrive. The impossible engine breaks both the third law and law of conservation of momentum. It is a closed cavity and does not produce any exhaust. It is a closed system with no output. And yet it produces thrust. Yeah, so a closed system can now generate thrust. Bye bye Newton.
