Possible formula for expressing entropic quantum gravity cosmologically?

Click For Summary
SUMMARY

This discussion explores a theoretical approach to expressing entropic quantum gravity in a cosmological context by modeling galaxies and black holes as mutually repulsive particles. The participant proposes a formula to calculate Lambda, the cosmological constant, using the equation E=mc² divided by averaged point masses, further divided by the distance to the observable universe's edge in light-years and Planck's constant. The idea challenges traditional views by suggesting the inclusion of dark matter as "perfectly explainable matter" (PEM), aiming to simplify complex cosmic interactions.

PREREQUISITES
  • Understanding of entropic quantum gravity principles
  • Familiarity with cosmological constants and their significance
  • Knowledge of E=mc² and its implications in physics
  • Basic grasp of astronomical measurements, particularly light-years
NEXT STEPS
  • Research the implications of Lambda in cosmology and its role in the universe's expansion
  • Explore the concept of dark matter and its alternative interpretations, such as "perfectly explainable matter" (PEM)
  • Study the relationship between mass, energy, and distance in astrophysical contexts
  • Investigate current theories in quantum gravity and their cosmological applications
USEFUL FOR

Astronomers, theoretical physicists, and cosmologists interested in innovative approaches to quantum gravity and the dynamics of the universe.

Sorry, I keep having naive little ideas lately! Humour me anyone if you so wish..

If you took the estimated mass of luminous/energetic bodies estimated in the observable universe (galaxies & black holes etc), disregard dark matter/energy, and make that each galaxy/observed mass can for convenience act as single mutually repulsive particles in a system;

What sort of value would you get for Lambda as an exponential if you took (E=mc^2 / the averaged point masses) / (distance to the edge of OU in LY / by Planck's constant)?

Does that make a lick of sense? I'm still thinking about it, don't be too cruel! :P

Ok, you can include dark matter, as long as you call it "perfectly explainable matter" - PEM.
 

Thread 'Questioning the timescape model'

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
