On the right, I have added a list of prejudices in fundamental physics that contradict experiments. The list is deeply depressing. The arxiv, especially the section hep-th, shows that practically all preprints adhere to at least one of the prejudices. I might have missed a few exceptions. So let me say, to be on the safe side, that 99% of all hep-th preprints are based on incorrect prejudices.
This is a disaster. What will historians of science say in 50 years? They will write that 99% of all researchers in fundamental physics in 2010 work on ideas that contradict experiment. And they will conclude that 99% of researchers in fundamental physics in 2010 are in a state of collective delusion.
A simple test confirms this collective delusion. Read Peter Woit's blog Not Even Wrong. Peter Woit is a hero, because he helped destroying the delusion of string theory. Go to his blog and add a relevant comment that questions either supersymmetry or higher dimensions, in the same way that he himelf questions string theory. What happens? He will delete your comment. Even though these two ideas are the basis for string theory and the reason for its failure, Peter Woit will not criticize them. So we are in a situation that even the harshest critic of string theory agrees with some of its prejudices. This does not take anything away from Peter Woit's heroism, but it shows how deeply ingrained some of the prejudices have become.
What remains? There is almost no research in fundamental physics that proposes a way out of all these ideologies and delusions.
Yes, there is the idea of entropic gravity. But what did it bring? No new results. No new predictions. No answer to any problem.
No, Steven Weinberg's idea of asymptotic safety does not count: it assumes that space is made of points. Anyway, it did not bring any new results, any new prediction, and any answer to the problems of the standard model.
So we have to answer: In theoretical fundamental physics, in the years from 1975 to 2010, nothing of lasting value has been produced.
Thirty-five years of failure by thousands of researchers, arguably among the smartest people on the planet. What a depressing disaster.
