Dark Matter is one of the biggest puzzles in science today. Astronomical observations tell us Dark Matter makes up 26% of our universe and experiences the gravitational force, yet we still know very little beyond this. The Large Hadron Collider (LHC) at CERN has been built to try and understand some of the long-standing questions in science. Over 10,000 scientists come together from around the world to run mankind's biggest experiment in history, discovering the Higgs boson in 2012 that explains the origins of mass, and continuing to search for new, exotic particles that could explain Dark Matter. I will introduce the LHC and the largest of the four main detectors, ATLAS. I'll show you how and why we search for a rich array of new particles predicted by Supersymmetry and the latest results from these searches. As the LHC program moves into its final stage, what further secrets of the universe will we uncover?

In my talk I will first introduce the basic principles and conjectures of the swampland approach to quantum gravity. Then I will concentrate on the problem of dark energy and dark matter, and how swampland relations possibly provide a clue to the understanding of these fundamental problems. I will discuss some possible interrelation between dark energy, dark matter and also about early inflation in the universe.
