Description

In this talk I want to discuss the (unorthodox) scenario when the baryogenesis is replaced by a charge separation process in which the global baryon number of the Universe remains zero. In this, the so-called axion quark nugget (AQN) dark matter (DM) model the unobserved antibaryons come to comprise the dark matter in the form of nuclear density nuggets. In this talk I specifically focus on two recent papers, see below. I will argue that a number of mysterious and puzzling observations recorded on Earth could be originated from this new paradigm when the DM is represented by strongly interacting objects. I will also argue that the Ball Lightnings which have been observed for centuries (however, this phenomenon has never been explained by known physics) is in fact a profound manifestation of the same DM physics.
