Stephen Hawking's search for aliens just got a major boost

Verily, "nothing" is undefinable and undefined in the same sense as the square root of negative 1.

followed your intent ....Lawrence Krauss articulates the challenge of nothing rather well...https://www.youtube.com/watch?v=YUe0_4rdj0U

but the "square root of negative 1"....is i...and the entry point to the realm of imaginary numbers...that see service in a variety of disciplines (EE to name but one)....

No, Laurence Kraus may be a good physicist, but he is a laughable philosophical ignoramus.

Of Nothing

More Sweet Nothings

GaryProtein is right when he says that the vacuum of empty space is not nothing, it is the vacuum of empty space.

Al - just to be clear..I was referring to Krauss in the physics context only...specifically around the quantum potential for energy to spontaneously emerge from the vacuum of empty space.

Probably not the best video to select for illustrating that specific aspect....philosophy i'll leave to others.

Ok, thanks for clarifying.
