My own theory is that there is no entanglement and no link between the particles, it is just that the particle states are affected the moment they are created.

My own theory is that there is no entanglement and no link between the particles, it is just that the particle states are affected the moment they are created. I also think that light is not a wave and that light particles are not fired in a straight line in the double slit experiment; they are fired at an angle, and then they bounce off the slits and create the interference pattern; and when we put a detector in front of the slits, it only serves as creating new light particles that do not have this angle in them and they go straight ahead, making the diffraction pattern disappear. And it's not that quantum math is wrong; it's right, but my intuition says that any system can be described by statistics. As for quantum mechanics applications, all the applications mentioned (from clocks to computers to anything the article and other articles mention) are not based in any QM specific property. None of those applications are actually dependent on entanglement and on collapsing the wave function, and entanglement cannot be used for any application despite what they write in articles because it would violate the principles of relativity. And none of those applications would cease to exist if light was not an actual wave and photons simply moved in wave patterns. Let the downvotes begin!
