When heated disputes arise between scientists, even a layman can often get a sense when something is amiss. An explanation of that sense is in order.
Physics, and especially mathematics, are the most empirical sciences we have. They are not like art or philosophy, in which differing opinions dominate the subject. Disagreements between physicists should be definitively settled after only brief presentations by each side. One expects the facts, not opinions, to decide the issue.
For example, even the awesome Stephen Hawking admitted to error regarding conservation of information in black hole stars. Hawking seemed absolutely certain that he was correct, but when those who disagreed with him laid out their case, Hawking recognized the truth and conceded. This is the way it should be.
Why is this not the case with quantum mechanics, and in particular, with quantum entanglement? Why is it that, after more than a century, quantum physicists are in strenuous disagreement over vital elements within the theory?
The core of the dispute goes back at least as far as Albert Einstein’s discourses with Niels Bohr.
The details of that dispute are well known to physicists. Most physicists seem to “side with” Bohr, Heisenberg and others. Einstein derided an important theory in quantum mechanics as “spooky action,” an insulting reference. Today, the dispute continues, with a minority of physicists rejecting certain vital concepts such as the “majority” interpretation of quantum entanglement.
The question, then, is not so much about “who is right,” or who is wrong. The more important question in my mind is, why does there remain so much intense disagreement? This is not politics, it is not literature, it is physics!
It is not as if the arguments of each side lack support. Both sides have published their arguments, using both experimental and mathematical expositions. These should be conclusive. I admit to not being able to understand the math, but those who are making the arguments can understand. Both sides can see the other’s evidence. Both sides can evaluate the math. In my view, the matter should have been settled long ago.
Why hasn’t it?
Certain scientific arguments can get clouded by politics, financial interests and/or personal rivalries. In such cases, the arguments of one side are subjected to censorship, dissembling, and even downright fraud. Examples of this can be shown in AIDS research, climatology and macroeconomics.
Is any of this present in quantum physics? Or is it that science has reached the outer edge of its map, beyond which one can only say, “here there be dragons?”
