In this StarTalk video, we’re talking about nothing. Not in the Seinfeldian sense, but in the science sense. What is nothing? Neil explains how our usual definition of something being “nothing” is dictated by our senses. What if you wanted to get all the way down to true nothing? Well, even when there’s nothing, there’s air molecules, and a lot of them. So, what happens when you take out the air molecules? Find out just how much air molecules permeate in our environment, in our solar system, in interstellar space, and intergalactic space. Then, just when you think you truly have nothing, you’ll hear how quantum physics comes into play. Discover more about virtual particles and why the best “nothing” you could have is filled with virtual particles. All that, plus, we debate if being able to describe something that is nothing makes it something.
