Will LQG explain the constants?

Click For Summary
SUMMARY

The discussion centers on the potential of Loop Quantum Gravity (LQG) to explain fundamental constants in physics, such as the fine-structure constant (alpha) and the cosmological constant (Lambda). Lee Smolin's Cosmic Natural Selection (CNS) model proposes that these constants may be optimized for black hole production, which in turn influences the reproductive success of universes. CNS is characterized as falsifiable, providing predictive outcomes that can be empirically tested, unlike anthropic principles which lack predictive power. The conversation emphasizes the need for further research to validate CNS and its implications for understanding the universe's fundamental constants.

PREREQUISITES
  • Understanding of Loop Quantum Gravity (LQG)
  • Familiarity with the fine-structure constant (alpha) and cosmological constant (Lambda)
  • Knowledge of black hole formation and its implications in cosmology
  • Basic principles of empirical testing and falsifiability in scientific theories
NEXT STEPS
  • Research the implications of Cosmic Natural Selection (CNS) on fundamental constants
  • Study the relationship between black hole formation and the evolution of physical constants
  • Explore empirical tests that could validate or falsify the CNS model
  • Investigate the role of Loop Quantum Gravity in resolving singularities in General Relativity
USEFUL FOR

The discussion is beneficial for theoretical physicists, cosmologists, and researchers interested in the foundations of quantum gravity and the optimization of physical constants in the universe.

I asked because I don't have $100 to spend on a textbook right now, even if its a classic that I've skimmed in a college bookstore a few times and longed to buy. Being a professor doesn't pay nearly as well as being a full time practicing lawyer.

we are both in the same boat Ohwilleke, sorry to say. But we must both be close to university libraries! Let's both get over to the physics departmental library and look this up----I just have secondhand references too and it is not really satisfactory.
