[Clermont]

Celna uwaga fizyka matematycznego Ursa Schreibera na temat teorii strun, której zarzuca się monstrualną liczbę rozwiązań i brak mechanizmu wybierającego te właściwe:

– All I know is that 10^500 is a very large number.

– It is a finite number. How many theories do you know which have a finite number of solutions? Have you tried to count the number of solutions of plain Einstein–Yang–Mills–Dirac–Higgs theory without its string-theoretic UV completion? There are not only infinitely-many solutions, there is a hugely infinite-dimensional space of solutions. This is the usual state of affairs for most every theory of physics ever considered. String theory is special in that it puts many more constraints on the solutions, such as to even leave just a finite number (under some assumptions).
