Incorporating the Cosmological Constant in a Modified Uncertainty Principle

Understand

This study explores the cosmological constant problem and modified uncertainty principle within a unified framework inspired by a void-dominated scenario.

• In a recent paper~\cite{Yusofi:2022hgg}, voids were modeled as spherical bubbles of similar average sizes, and the surface energy on the voids' borders was calculated across various scales in a heuristic manner.
• We show that this results in a significant discrepancy of approximately $\mathcal{O}(+122)$ between the cosmological constant values from the minimum to the maximum radii of bubbles.
• Furthermore, when considering the generalized form of the uncertainty principle with both minimum and maximum lengths, i.e.
