What is the relationship between quantum field theory and string theory?
 
Physics news on Phys.org
If string theory is proven correct, then quantum field theory should be deduced from it where quantum theory holds.
 
quantum field theory is always a limit of string theory*. for example, you can deduce things like scattering amplitudes of gluons and gravitons from string theory.

*probably too strong of a statement, it might be possible for some qft's to not be generalizable to string theory (in a non trivial way at least)
 

Thread 'Gravitational self-interaction: another attempt to replace Dark Matter'

https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...
