String Theory is only a first-level hypothesis, not a theory. Alexander Unzicker has all sorts of excellent criticism of modern physics. It is not a good idea to stay we should not have negative criticism of the current physics. It is important to see where the holes are. In addition, why do physicists keep criticizing the best theory we have so far? A theory that explains many of the biggest questions that the Standard Model completely fails at, like what is matter, what is energy, what happened before the Big Bang?
