Q&A 104: Should We Reconsider The Definition Of A Moon? And More...

In this week's questions show, I explain why it's probably not time to reconsider the definition of a moon, if we could make artificial gravity with a chunk of a neutron star, and why a supermassive black hole isn't the anchor for an entire galaxy. 00:47 Should we reconsider the definition of a moon? 03:35 Could we make artificial gravity with mass? 05:48 Why didn't the Big Bang collapse back into black hole? 07:47 Why can't a black hole be the anchor of the galaxy? 10:45 How far and how small can we see? 13:37 What is left after a black hole evaporates? 15:00 Could you have a star made out of something else? 16:32 Could a planet orbit a binary star? 18:29 Could aliens Planet 9? 19:24 If aliens are advanced, we're no threat 21:35 How can aliens not exist? 22:30 Why don't they put a microscope in a rover?
