Dark Matter Day 2025: Searching for Dark Matter

Why does anything exist at all? What holds galaxies together? And what secrets lie in the invisible scaffolding of the cosmos? These are just a few of the questions at the heart of Dark Matter Day 2025, a global celebration of one of the greatest scientific mysteries of our time — and Kingston is joining the search.
On Saturday, November 8th at 6:30 PM, head to Stirling Hall at Queen’s University for an illuminating and accessible public talk by Prof. Joe Bramante, a leading astroparticle physicist. Prof. Bramante will guide audiences through the fascinating world of dark matter: the elusive substance that makes up roughly 85% of the matter in the Universe, yet remains undetectable by conventional means.
This free event will dive into cutting-edge theories and experiments, showing how scientists are using the largest particle colliders in the Universe — like stars, galaxies, and black holes — to hunt for traces of this hidden material. Whether you’re a seasoned science enthusiast or simply curious about the cosmos, this is your chance to connect with one of the most exciting frontiers in modern physics.
After the talk, explore a hands-on science fair hosted by Queen’s Physics students and researchers, followed by a special evening visit to the Queen’s Observatory, where (weather permitting) guests can gaze through the historic telescope and reflect on the vastness of space.
Come discover how the “dark side” of the Universe may hold the answers to why we’re here at all.
