Everything we see in the universe makes up only a paltry 4 per cent. The rest is "dark". We know remarkably little about it other than what we call "dark energy" is causing the expansion of the universe to accelerate, and that "dark matter" is holding galaxies like our own Milky Way together. Scientists think that dark matter is everywhere, streaming through you as you read this right now. Understanding the nature of this mysterious dark matter is one of the most important scientific missions of our time. In this talk we will travel to the frontiers of dark matter research, where we seek dark matter collisions in highly sensitive detectors buried deep under the Earth’s surface; watch for signatures of dark matter annihilations in space; and even try to produce fresh dark matter in particle colliders. We may even visit the spooky realm of quantum mechanics for clues. The hunt for this elusive substance is heating up we may soon be stepping out into the dark. Chamkaur Ghag is an astroparticle physicist at University College London. Chamkaur completed his undergraduate MSci degree in astrophysics at the University of London in 2003 before moving to the University of Edinburgh where he completed his PhD in 2006, researching novel technologies to detect dark matter. He held post-doctoral positions at the University of Edinburgh and University of California Los Angeles, continuing his dark matter research and contributing to the world-leading experimental searches, before moving back to the UK in 2012 to start dark matter research in the high energy physics group at UCL. Chamkaur is a member of the LUX and LZ experiments, and leads the Boulby Underground Low-Background Assay Facility. He is also the current chair of the dark matter UK consortium and the chair of the STFC’s particle astrophysics advisory panel. Precise cosmological measurements coupled with astronomical evidence tell us we live in a universe made up of contributions of 68% from ‘Dark Energy’.
