MDPI Webinar | Dark Matter Day, Session 2, 31 October 2025
MDPI is excited to announce a special webinar in celebration of Dark Matter Day, which will take place on 31 October 2025. This event will explore the mystery of dark matter, which makes up 26.8% of the universe's mass and energy, yet remains largely unexplained. Along with dark energy, which drives the universe’s expansion, dark matter plays a crucial role in the cosmos. Join us as we explore the dark sector of the universe and discover how these insights could reshape our understanding of the cosmos’ structure and history.
Date: 31 October at 8:00 a.m. CET | 3:00 p.m. CST Asia
