What's the Biggest Problem in Quantum Physics?

There's just a broader spectrum on quantum physics, interpretation of what reality is all about. The Kowatake interpretation stops short of saying that it's actually a human mind. We have collapsed out of that quantum soup into real things. An extension of the quantum theory goes beyond even this. It paints a picture in which solid matter dissolves to be replaced by weird excitations and vibrations of invisible field energy. Quantum physics undermines materialism because it reveals that there has far less substance than you might believe.
