Welcome message by Prof. Dr. Konstantin Zioutas, Webinar Chair:

Physics is full of unanswered questions. In space science, we are faced with a large number of observations of unknown origin, even within our solar system. We recall, as an example, the historic observation in the 1930s by Fritz Zwicky of some suspected matter in the universe, which he called “dunkle Materie”, also known as dark matter. Dark matter (DM) dominates the universe, with its mass being about five times that of the normal matter we, the planets, the stars, etc., are made of. After 90 years, we can only suspect the microscopic constituents of DM, and assume that it interacts gravitationally. Thus, we live inside a well-hidden, dark universe. Undoubtedly, it is of utmost importance to identify the nature of DM. Therefore, it is safe to predict that the expected discoveries at present will overshadow historical discoveries. This is a challenge but also a unique opportunity for people fascinated by the unknown. The study of DM is exciting and highly motivating. In particular, for young people faced with the decision of choosing an exciting and rewarding career, astroparticle physics might just be the choice. Delving deeper into this exploration of DM, we pose some questions that we excitedly await the answers to:

What is dark matter? What is dark energy? Why is there an arrow of time? Are there parallel universes? Why is there more matter than antimatter? What is the fate of the universe? Is string theory correct? Do the universe's forces merge into one? What happens inside a black hole? What lies beyond the Standard Model? Fundamental constants? Do living things sense the dark universe?  

In this webinar, we will hear from two experienced physicists (Prof. Dr. Ariel Zhitnitsky, Canada, and Prof. Michael Tobar, Australia), as well as two physicists who are just beginning their promising careers in this area (Prof. Dr. Abaz Kryemadhi, USA, and Dr. Javier Miguel, Spain).

All four speakers work at the forefront of physics research, and therefore they will provide an appropriate introduction to this topic.

Date: 25 May 2023 at 4:00 p.m. CEST | 10:00 a.m. EDT | 10:00 p.m. CST Asia
