X-59 test flight and new findings on black holes and the universe

NASA conducted the first test flight of its experimental X-59 supersonic jet, designed to reduce sonic booms. The X-59 aims to overcome a major obstacle to supersonic flight, potentially allowing faster travel over populated areas. Future tests will assess its noise levels. This development follows a week of scientific news including hints of second-generation black holes and a proof that the universe is not a simulation.
