Random walk and universal expansion

Click For Summary
SUMMARY

The discussion centers on the relationship between Hubble expansion and random walk theory in the context of cosmology. It highlights a deterministic link between the universe's content and Hubble expansion, referencing general relativity as the foundational framework. Loren's suggestion draws parallels to E. A. Milne's Kinematic Relativity cosmology, specifically his introduction of 'K Calculus' in 1935. This connection indicates a potential alternative perspective on cosmic expansion mechanisms.

PREREQUISITES
  • Understanding of Hubble's Law and cosmic expansion

Can the Hubble expansion be explained in terms of spacetime events undergoing a random walk?
 
Astronomy news on Phys.org
There is a deterministic relation between the content of the universe and the Hubble expansion, at least in most (all?) of the cosmological models based on general relativity.
 
However Loren's suggestion is similar to E. A. Milne's Kinematic Relativity cosmology. (Relativity, Gravitation and World-Structure 1935) in which he first describes what is now known as 'K Calculus'.
