Which raises the question: Why haven't we met any visitors from another time? » 10/09/14 3:39pm 10/09/14 3:39pm

Spielberg Gets His "2001" On With Wormhole Saga

Thorne. Interstellar, produced (and maybe directed) by Steven Spielberg, will deal with travel through a wormhole into an… » 3/19/08 11:31am 3/19/08 11:31am
