    • I think it’s pretty ironic that way back in the 70s or 80s that Carl Sagan was doing everything possible to encourage finding aliens, including his book “Contact” which was made into a movie, and now Stephen Hawking is saying they’re probably dangerous and we should hide. Seems like any alien civilization advanced enough to find us can do pretty much as they please.
