>>11620337I literally posted a link to a video which explains this which you could have watched. But basically, if unitarity was not true, then the probability of certain properties of quantum states would not sum to 1, meaning you could have impossible things like the probability of an electron being in a certain region of space being 300% or something.
>Experiments also “””confirmed””” other hypothesesIf i’m going to be technical, i don’t think quantum theory nor relativity are truly “right” because they are not theories of everything. But they are incredibly accurate APPROXIMATIONS of that.
I don’t know how you could say QFT is on the right path but you need to get rid of einsteinian relativity to improve it. “Einsteinian relativity”, once incorporated with Quantum Theory made Quantum Theory MORE accurate. antiparticles popped up in the equations once this was done, which have been observed (it follows from E= mc^2). Classical Electromagnetism, special relativity and quantum theory are all unified in Quantum Electrodynamics which is the most accurate physical theory of all time.
