Quantum gravity is the holy grail for modern theoretical physicists – a single structure bringing together the two great theories of the 20th century: quantum mechanics and general relativity. One solution is string theory, which emerged from particle physics. In this talk, Jim Baggott describes the other approach known as Loop Quantum Gravity. This theory starts from general relativity, borrows many ideas and techniques from quantum mechanics, and predicts that space itself is quantum in nature
