You may have heard about the extensive testing facilities for spacecraft and equipment, but how do scientists prepare for the human aspect of space exploration?
A few days ago, I wrote about non-singular black hole models, specifically one known as the Hayward model. Since its introduction in 2006, several variations of the Hayward model have been introduced, including a rotating model similar to the Kerr metric used to study the supermassive black holes we've observed directly. This raises an interesting question: what if we use a rotating Hayward model instead of the usual Kerr model? A recent study answers that question.
