The current impasse in fundamental physics stifles progress. The rate of advances in our understand has slowed down. Although several exotic predictions have been made in recent years, none of these seem to be correct. Have we reached the end of our ability to learn more about the universe we live in?
It has been suggested that the way forward is to go back and fix what is wrong. Is there then something wrong with what we’ve learned before? Apparently yes. We are biased by what we think we know. It misleads us to conjure up theories that cannot work.
How is this possible? Would such misconceptions not have been ruled out by experimental observation? That’s the problem. Much of what we think we know never got tested by experimental observations.
As an example, one is reminded of all the aspects of quantum physics that is not currently understood. Yes, we know enough about quantum mechanics (the mathematical formalism) to do calculations. The problem is that we then go and interpret what we see. That part cannot be tested by experiments.
For example, in certain interpretations of quantum mechanics it is believed that the wave function collapses to produce (or because of) the result we observed. Nobody really knows how this works. This is the measurement problem, which is currently a hot topic in quantum foundations.
But is this even science? How is this going to help us move forward? It occurs to me that these types of problems require us to step out of this struggle and get some distance from it. I said elsewhere that wisdom is the path to knowledge. Perhaps we need to get the metaphysics right before we will be able to get the physics right. We need to separate that which we can learn from a scientific approach from that which cannot be investigated scientifically.
Perhaps there is not such a clear cut distinction between those aspects of quantum physics that can and cannot be studied scientifically. However, it is not difficult to see where we are bound to waste much time with potentially limited or no advances.
In the following posts, I intend to address some specific aspects of the current impasse and how it impacts our current understanding. Although I’m not a fan of philosophy, some of these discussions may touch on some philosophical aspects of the topic – the metaphysics – in as far as it may show us the way.
