Explore a comprehensive lecture by Marek Liška from the Dublin Institute for Advanced Studies (DIAS) examining the proposal of a universe with unbroken CPT symmetry developed by Latham Boyle, Kieran Finn, and Neil Turok. Discover how this theoretical framework offers an explanation for dark matter as right-handed neutrinos produced through the Hawking effect. Learn about new perspectives on fundamental cosmological problems including flatness, homogeneity, and isotropy, as well as potential insights into the origin of the cosmological constant. The lecture also delves into how enforcing CPT symmetry could resolve black hole singularities by replacing them with regular, mirror-like geometry. This 80-minute presentation provides a thorough review of cutting-edge theoretical physics concepts that challenge conventional understanding of universal structure.
