Black Holes Have Soft Hair
by Scott Melville figures by Shannon McArdel and Michael Gerhardt You’ll never guess how Google autocompletes: “Do black holes have…” The answer: “…no hair?” This strange question has been debated by physicists for at least forty years, and today it seems we may be approaching an even stranger answer: They have soft hair. That is, at least, according to Stephen Hawking, who visited Harvard in … Continue reading Black Holes Have Soft Hair
LIGO and Gravitational Waves: Discovery of the Century
The Twitter rumors are true! In what some scientists are calling the discovery of the century, LIGO (Laser Interferometer Gravitational-Wave Observatory) finally announced the first direct observation of gravitational waves. Until a few days ago, gravitational waves were the only untested prediction of General Relativity. In General Relativity, space and time are not fixed. Spacetime curves around the matter and energy in the universe, … Continue reading LIGO and Gravitational Waves: Discovery of the Century
Stephen Hawking Makes Big Claims about Black Holes
Stephen Hawking recently announced that he has solved one of the most famous puzzles in science, the black hole information paradox. The information paradox is a conundrum of Hawking’s own making. In the 1970s, he predicted that black holes radiate, evaporate, and eventually disappear. This scenario is particularly concerning, because once inside a black hole, nothing can escape. If a black hole were to completely … Continue reading Stephen Hawking Makes Big Claims about Black Holes
