Cosmic Queries - Death of a Black Hole
Neil deGrasse Tyson hosts a Cosmic Queries Grab Bag edition, answering listener questions on topics ranging from why eclipses do not happen every month to the evaporation and final moments of black holes. He discusses dark energy and why external gravitational tugs are unlikely to explain it, defends the term "black hole," explores time travel paradoxes and Hawking's chronology protection idea, and explains Jupiter's shielding role in the solar system. The episode also covers entropy and why life on Earth does not violate the second law of thermodynamics, relativistic addition of velocities, the distinction between space and time dimensions, the value of scientific literacy, and what "vacuum" and "nothing" really mean in physics.
