This is Scientific American 60 second Science, I’m Steve Mirsky
Nothing was on the table at the annual Isaac Asimov Memorial Debate March 20th at theAmerican Museum of Natural History in New York City. Here’s Hayden PlanetariumDirector Neil deGrasse Tyson talking with journalist Jim Holt, author of WhyDoes the World Exist, and physicist1 Lawrence Krauss, author of A Universe fromNothing.
So Jim,when did philosophers start weighing in on this?
Reallywith Leibniz in the 17th century. He was the first thinker to pose the question“why is there something rather than nothing.” And by nothing, he meant a statein which there are no existence at all, there are no entities2, there’s no chaos3, there’s no space, no time, absolute nothingness. It’s very difficult tograsp in the imagination. If you try to obliterate4 all of the contents of your consciousness or try to imagine all of the contents of the universe slowly being extinguished, the stars going out, the atoms disappearing, lifedisappearing, time and space disappearing, even when you try to reach nothingness in your imagination, there’s still the little light of your consciousness creeping under the door. I actually, the only times I’ve succeeded in imagining absolute nothingness is during dreamless sleep and once while I was watching professional bowling5 on television.
I think that what Jim has pointed6 out is exactly it. You’re absolutely right, there are some things that are essentially7 impossible to get an intuitive conception of.And that’s just a limitation of the fact that we’re classical human beings who didn’t evolve to intuitively understand quantum mechanics. So there’s lots ofthings in science that are impossible to get any intuitive handle on, but that doesn’t mean they don’t exist.
I completely agree with you. And I think that a state of absolute nothingness,even though we can’t envision it in our minds, it’s logically consistent, it’sa real possibility, and there is a genuine question—why is there a universe rather than absolute nothingness?
For Scientific American 60 second science, I’m Steve Mir sky.
It’s about nothing.
So we’re coming on in with saying telling an idea for a show about nothing.
Exactly!
They say what your show about? I say nothing.
Here you go.
I think you might have something here.
