Neil deGrasse Tyson Explains Why You Can’t Reach Absolute Zero

Cool things happen at low temperatures. In this StarTalk explainer, we’re cooling things down – way down. But how cold can we actually get? Neil deGrasse Tyson and comic co-host Chuck Nice investigate the limits of temperature and a lot more.

You’ll learn why there’s really no limit of how hot you can make something. On the flip side, we dive into why making things colder is a different story. How do you create a place where there is no heat? You’ll find out more about the Kelvin scale or absolute temperature scale.

Neil takes us through the process of cooling things down. Discover the differences between temperature and heat energy. We explore the vibration of particles and dip our toes into Maxwell–Boltzmann distribution. Then, Neil tells us why we can never philosophically or theoretically reach absolute zero.

To wrap things up, we investigate what happens when quantum physics take over. Discover more about superfluidity. All that, plus, you’ll hear about the Bose–Einstein condensate and how we can “shape-shift” matter.
