Matt O'Dell: How do we know Black holes follow the second law of thermodynamics? He says entropy is something that just emerges from the way particles interact with each other, but it also seems like one of the most fundamental things in physics. "No matter where you look, entropy seems to increase," he says. 'We tend to lose more and more of the information of a system over time.'
Can we use gravitational lensing to view distant planets? Neil deGrasse Tyson and comedian Chuck Nice explore black holes, quasars, entropy, and more with astrophysicist and host of PBS Space Time, Matt O’Dowd.
