This is arguably the most profound question there is and one that may seem completely outside the scope of particle physics. But our new experiment at CERN's Large Hadron Collider has taken us a step closer to figuring it out.  The Antiproton Decelerator (AD), sometimes known as the Antimatter Factory, is the world's largest source of antimatter and has been operational since 2000.  Positronium atoms, which consist of an electron and a positron, are one type of antimatter atoms being considered to test whether antimatter falls at the same rate as matter in Earth's gravitational field.
