Do We Live in the Center of the World?
Andrei Linde, Dmitri Linde, Arthur Mezhlumian

TL;DR
This paper explores the energy density distribution in a stationary inflationary universe, revealing that most volume concentrates near the centers of deep density holes, which may imply observers typically find themselves at the universe's center.
Contribution
It demonstrates that in a stationary inflationary universe, volume distribution is concentrated near density minima, offering insights into observer location and implications for quantum cosmology.
Findings
Volume concentrates near centers of density holes
Observers are likely to see themselves at the universe's center
Potential observational deviations could inform quantum cosmology
Abstract
We investigate the distribution of energy density in a stationary self-reproducing inflationary universe. We show that the main fraction of volume of the universe in a state with a given density at any given moment of time in synchronous coordinates is concentrated near the centers of deep exponentially wide spherically symmetric holes in the density distribution. A possible interpretation of this result is that a typical observer should see himself living in the center of the world. Validity of this interpretation depends on the choice of measure in quantum cosmology. Our investigation suggests that unexpected (from the point of view of inflation) observational data, such as possible local deviations from , or possible dependence of the Hubble constant on the length scale, may tell us something important about quantum cosmology and particle physics at nearly…
