This clip is a 2.6-second burst of Neil deGrasse Tyson laughing, a warm hearty chuckle that rises fast. It feels friendly and amused, signalling playful disbelief at something clever or absurd rather than mockery. The laugh comes from the American astrophysicist and science communicator whose interviews and television appearances are widely clipped online.
