Will there be a Nobel Prize in Physics awarded for work in string theory before 2050?

String theory

roughly speaking, replaces point particles by strings, which can be either open or closed (depends on the particular type of particle that is being replaced by the string), whose length, or string length, is approximately 10^(−33) cm. Also, in string theory, one replaces Feynman diagrams by surfaces, and wordlines become worldsheets.

In late 2019 John Horgan won a 2002 longbets.com bet with physicist Michio Kaku that by 2020 no unified theory of physics will win a Nobel Prize.
