Read this paper, please. Read the abstract. Read the paper. Enjoy the first page. This is the kind of papers showing that string theorists have departed in another world and lost touch with reality.
Nobody in his right mind would ever write such a text. This is a Sokal hoax in a physics journal. And it is ongoing. Sokal performed a hoax, he was healthy. Lust is convinced, he is sick.
String theory is not about nature, not about reality, and not about a theory of everything. It is about a group of people in a shared fantasy world. What a tremendous suffering for all those involved. Who can help them?
