NASA has solved physics, though: https://www.nasa.gov/X59 https://www.nasa.gov/X59 The Low-boom Flight Demonstration mission has two goals: 1) design and build a piloted, large-scale supersonic X-plane with technology that reduces the loudness of a sonic boom to that of a gentle thump; and 2) fly the X-plane over select U.S. communities to gather data on human responses to the low-boom flights and deliver that data set to U.S. and international regulators. Using this data, new sound-based rules regarding supersonic flight over land can be written and adopted, which would open the doors to new commercial cargo and passenger markets to provide faster-than-sound air travel.
