Which branch of physics is the most fundamental one?

Click For Summary
SUMMARY

The discussion centers on the exploration of fundamental branches of theoretical physics, particularly focusing on String Theory, Quantum Gravity (QG), and Quantum Field Theory (QFT). Participants express skepticism about the viability of Particle Physics as a research field, suggesting that QFT is more fundamental and applicable, especially in condensed matter physics. The conversation emphasizes the importance of understanding the nature of physics as a blend of experience and mathematical abstraction, highlighting the ongoing search for a unified understanding of the universe.

PREREQUISITES
  • Understanding of Quantum Field Theory (QFT)
  • Familiarity with concepts of Quantum Gravity (QG)
  • Knowledge of Particle Physics and its applications
  • Basic grasp of mathematical frameworks in physics
NEXT STEPS
  • Research the implications of Quantum Field Theory (QFT) in condensed matter physics
  • Explore the current challenges in Quantum Gravity (QG) research
  • Investigate the historical development of theoretical physics from Newtonian mechanics to modern theories
  • Study the philosophical implications of mathematical constructs in physics
USEFUL FOR

This discussion is beneficial for undergraduate physics students, theoretical physicists, and anyone interested in the foundational aspects of physics and its philosophical underpinnings.

I argue that 'truth' is a very ambiguous word that has a lot of emotional connotation.

Quantum cosmology.

It seems to be interesting branch. Is this sexy, competetive field with no funds and perspectives for interesting reaserch or does it depend on speciality?

Quantum cosmology is a fundamental field for the future, relating diametric extremes of physics. For instance, there have been inroads on how one might explore the Planck realm indirectly (Physics Today).
