All to true in physics... if i punch a brick wall with sufficient force, it will exert an equal and opposite force on my hand, quite possible breaking the bones. This is NOT the same equal and opposite reaction that will occur if I punch my brother in the face. That is a reaction, but it has absolutely nothing to do with newonian physics.... and as for this non-existence existing... if you take a virtual container, with no substance or mass, and put into it all other empty containers, does the first container contain itself? The idea of non-existence exists, but the fact that I don't have a sister implies that I do have a sister is absolute garbage. The notion of my not having a sister exists because I don't have one, otherwise that notion would be false. Similarly, if something doesn't exist, then perhaps, and I emphasize that word, the notion of it not existing exists. However, if that were true for all objects in non-existence, then the definition of the word invention would be completely false as all things that did not exist and were invented were actually always there. So I guess the main bullet point here is that I disagree with your statement. BTW weird story, but not a bad one
