1 Void-Dominated Cosmology: Looking for Dark Energy in the Kitchen

This talk addresses key challenges in modern cosmology and introduces the motivations for a "void-based cosmology". In this approach, voids (bubbles) are treated as independent, dynamic components of the cosmic web next to clusters (drops). Drawing inspiration from the behavior of heated milk overflowing, the presentation will examine the connection between void surface tension and the cosmological constant, the modified uncertainty principle, and the evolving dark energy density resulting from void mergers on cosmic scales.

Speaker: Dr Ebrahim Yusofi (Amol University and IPM)
