If we wanted to hide Earth from alien civilizations, could we do it? Apparently, we could, according to new work by two scientists at Columbia University.

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.

I figure that aliens would be like humans – some nice and helpful, others wanting to make a profit at our expense and every other attribute human’s display.

Right, some like ET and others like the aliens in “Independence Day” which I just happened to watch last night.

Exactly! We can claim a dog is anything from teacup size to humongous and have all sorts of colors, shapes, abilities, so why would be expect aliens to come from one mold?
