Prof. Gerald Cleaver is a noted theoretical physicist in string theory at Baylor University and a member of the Icarus Interstellar team. In this video of a luncheon presentation at NASA JSC,  he gives a fascinating talk (aimed at a general audience) about the Icarus group, about interstellar flight, the possibilities of making Alcubeirre Warp Drive a reality (he says string theory is key!), and a couple of ways to create large amounts of antimatter for propulsion :
