Alas, once again I've been passed over for the Edge question. Still, I can join with everyone else in marveling at the answers. Here are some (quoted):

  • We may all die horribly unless some scientists figure out a way to save us
  • Each cubic centimeter of empty space contains about 10-29 grams of invisible matter, or, equivalently, vacuum energy
  • Cephalosomatic Anastomosis" (CSA) (a.k.a. a complete head transplantation)
  • Any gene (or set of genes) can be forced to "drive" through an entire wild population.
  • The race between the growing power of technology and the growing wisdom with which we manage it.
  • Tabby's Star - the possibility that the dimming effect is caused by a swarm of Dyson Spheres

And many many more. Enjoy.
