If you don’t want to actually change quantum mechanics, you can try to interpret the mathematics differently and hope that then it makes more sense. There are a number of such interpretations. For example, there’s the interpretation proposed by Niels Bohr, according to which the wave function just shouldn’t be considered real. It’s a device to make predictions for measurements, Bohr said, but if you are not making a measurement, it is meaningless to ask what is really happening. This is now often called the Copenhagen interpretation or just the standard interpretation, because it’s the most
