Is theoretical physics stuck in a rut?

1 Answer

Answer :

answer:I’d say that we are in a period of relative stagnation. Part of it has to do with the fact that most other nations don’t have the resources (labs, education, super-geniuses…) and the one nation that arguably has the most is actively anti-intellectual. Further knowledge is possible, but without the will to learn, we don’t have even a chance of obtaining it.
