By probing, I mean looking beyond predictions, the underlying nature of it. The equations of QM give us great results but it is very much an oracle type situation. We ask a question and we get a good answer. But why? Theoretical physicists are told not to look behind the equations and figure more out. Why is it this way?

Let me be frank I am getting way outside my true understanding and parotting what I have read. But if QM the way it is because it fits the many worlds theory? Are we missing another piece to explain it? If you take the simplest version of QM that can solve the problems, you are stuck with many worlds.

These are important areas that colliders aren't going to answer but physicists push new physicists to avoid.

There are other theories but require dressing up the base QM math to eliminate many worlds.

Very few are doing work in this area
