Questions include: What is the history of black holes discovery? - Is gravitoelectromagnetism sufficient to get black holes with event horizon or do you need the full GR framework to get them? - Ernst Mach has a great book on history of mechanics (reading at the moment). The whole development of General relativity is very German until like Hawking and Chandrasekhar. ​Did you ever meet Stephen Hawking or Chandrasekhar? - Is there an instance or phenomenon where an instrument uses a theory to test or advance that theory... is there a something like Godels incompleteness theory that applies to the instruments in physics? - What is the history of UFO observations? - There was a new physics announcement from CERN this week. something about a new kind of force. did you catch it Stephen?
