Believe it or not I'm having trouble understanding quantum physics. If we take the double slit experiment and one photon is sent through the slits at a time an interference pattern is formed. From what I've read the particle goes through both slits and interferes with itself. Now when it says interfere is it taking in a general sense or does it mean that the particle will hit itself to interfere with itself? I also don't understand why we just assume that the particle is going through both slits and then interferes with itself. It's just as crazy to say that the particle is only going through one slit and then takes two directions at the same time hitting different positions on the screen which just so happen to cause an interference pattern. I think the attitude quantum physics takes that it can't be proved wrong so it must be right type of attitude is very poor. If we can't measure the state that the particle is in then we should only conclude that it makes an interference pattern but we shouldn't start pretending that we know what is happening to the particle before it hits the screen. I hope you can at least clear a little bit of my confusion. Thanks in advance.
