When it comes to Absolute Zero, Dr. Anita Sengupta is a total tease. Her new project, The Cold Atom Laboratory, cools atoms down to a fraction of a degree above Absolute Zero in order to create and verify a new state of matter first postulated by Einstein. Attaining Absolute Zero is impossible, as it would create a waveform that would take over the universe. We get into that, as well as cooling things with lasers, her love of tortured souls, and sonic toothbrushes.
