SUMMARY

The discussion centers on the necessity of gravitation in the context of unification theories, particularly Grand Unified Theories (GUT). Participants highlight that while other fundamental forces are well represented in GUT, gravitation poses unique challenges due to its nature as a property of space-time, as described by General Relativity (GR). The incompatibility of quantum field theory with curved space-time complicates the integration of gravitation into these unification frameworks, especially in extreme conditions like black holes.

PREREQUISITES
  • General Relativity (GR) principles
  • Quantum Field Theory (QFT) fundamentals
  • Understanding of Grand Unified Theories (GUT)
  • Concept of curved space-time
NEXT STEPS
  • Explore the implications of General Relativity on quantum mechanics
  • Research current approaches to integrating gravitation into GUT
  • Study the behavior of quantum fields in curved space-time
  • Investigate the latest findings in black hole physics and their relation to unification theories
USEFUL FOR

Physicists, cosmologists, and students of theoretical physics interested in the interplay between gravitation and quantum mechanics, particularly in the context of unification theories.

just came to my mind to ask: Is gravitation really a fundamental force? As far as I recall from my GR lecture, gravitation is a property of space-time. Other forces seem to be well described by the grand unified theories (GUT).

So why is there still a need to include gravitation?

cheers!
:-p

GUT is an open problem itself.
Apart from that, you cannot simply work with quantum field theory in a curved space. Or at least it is unclear how that could be done.
 
In regimes where general relativity and quantum theory are both needed (inside black holes), they are incompatible.
