Can the Hubble expansion be explained in terms of spacetime events undergoing a random walk?

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'.

Related to Random walk and universal expansion

1. What is a random walk and how does it relate to universal expansion?

A random walk is a mathematical concept that describes the movement of a particle or object that takes a series of random steps. In the context of universal expansion, a random walk can be used to model the movement of galaxies as they are affected by the expansion of the universe.

2. How does the concept of a random walk help scientists understand universal expansion?

The random walk model allows scientists to study the distribution and movement of galaxies over time, providing insights into the expansion of the universe. By analyzing the patterns and statistics of the random walk, scientists can make predictions and test theories about universal expansion.

3. Can a random walk accurately represent the complex process of universal expansion?

While a random walk is a simplified model, it has proven to be a useful tool for understanding universal expansion. More complex models, such as computer simulations, also incorporate the concept of a random walk to better represent the intricate dynamics of the universe.

4. Are there limitations to using a random walk in studying universal expansion?

Like any model, a random walk has its limitations. It assumes that the movement of galaxies is completely random, which may not always be the case. Additionally, it does not account for other factors that may influence universal expansion, such as dark energy or the effects of gravity.

5. How does the concept of a random walk tie into the overall understanding of the universe?

The random walk is just one tool in the toolkit of scientists studying the universe. Along with other models and observations, it contributes to our overall understanding of universal expansion and how the universe has evolved over time.
