A little over 100 years ago, in 1915, Einstein published his theory of general relativity, which is sort of a strange name, but it's a theory that explains gravity. It states that mass -- all matter, the planets -- attracts mass, not because of an instantaneous force, as Newton claimed, but because all matter -- all of us, all the planets -- wrinkles the flexible fabric of space-time. Space-time is this thing in which we live and that connects us all. It's like when we lie down on a mattress and distort its contour. The masses move -- again, not according to Newton's laws, but because they see this space-time curvature and follow the little curves, just like when our bedmate nestles up to us because of the mattress curvature. (Laughter) A year later, in 1916, Ei...
