Chasing Shadows: How Scientists Hunt for Dark Matter
Dr Cenk Turkoglu
Subud Centre, Lewes BN7 2DS

Dark matter is one of the greatest mysteries in modern physics. Although it makes up most of the matter in the universe, it neither emits nor absorbs light, leaving its presence revealed only through its gravitational effects on galaxies and cosmic structures. In this talk, Dr Cenk Turkoglu will explore what we know about dark matter, why we believe it exists, and how scientists around the world are developing ingenious experiments to detect it. From deep underground detectors to space-based instruments, he will discuss the ongoing global effort to uncover the true nature of this invisible component of our universe and the challenges that make this quest one of the most fascinating frontiers in science today. Everyone is welcome. Non-members £4.

Everyone is welcome. Non-members £4.
