Possible formula for expressing entropic quantum gravity cosmologically?

In summary, the conversation discusses the idea of using the estimated mass of luminous and energetic bodies in the observable universe to calculate a value for Lambda as an exponential. This calculation would involve disregarding dark matter and treating each galaxy as a single mutually repulsive particle. The conversation also considers the inclusion of dark matter, referred to as "perfectly explainable matter" or PEM.

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.
 

1. What is entropic quantum gravity?

Entropic quantum gravity is a theoretical framework that attempts to unify the laws of quantum mechanics and general relativity by incorporating concepts from thermodynamics and information theory. It suggests that gravity is an emergent phenomenon arising from the microscopic structure of spacetime.

2. How does entropic quantum gravity relate to cosmology?

Entropic quantum gravity has been proposed as a possible solution to the cosmological constant problem, which is the discrepancy between the observed value of dark energy in the universe and theoretical predictions. It also offers a potential explanation for the accelerated expansion of the universe.

3. What is the significance of finding a formula for expressing entropic quantum gravity cosmologically?

Finding a formula for expressing entropic quantum gravity cosmologically would provide a mathematical framework for understanding the behavior of spacetime at both the microscopic and cosmological scales. It could potentially lead to a more complete theory of quantum gravity and provide insights into the origins and evolution of the universe.

4. Has a formula for expressing entropic quantum gravity cosmologically been discovered?

No, a definitive formula for expressing entropic quantum gravity cosmologically has not yet been discovered. This is an ongoing area of research in theoretical physics and cosmology.

5. What are the challenges in developing a formula for expressing entropic quantum gravity cosmologically?

One of the main challenges in developing a formula for expressing entropic quantum gravity cosmologically is the lack of experimental evidence and the complexity of the underlying theories. The mathematics involved is also highly theoretical and may require new mathematical frameworks to fully understand and express it.
