A public talk announcing the conjecture that the strong-coupling limit of type IIA string theory is 11-dimensional supergravity KK-compactified on a circle is at 15:12 .
19:33 " Ten years ago we had the embarrassment that there were five consistent string theories plus a close cousin , which was 11-dimensional supergravity . "
19:40 " I promise you that by the end of the talk we have just one big theory . "
