LatestEven as the New York Times brought credibility and a broad audience to the question of UFOs and extraterrestrial life, other figures challenged whether it might all be a great big lie. But when an acclaimed Harvard psychiatrist named John Mack began investigating the phenomenon now known as alien abductions, he proved that these bizarre experiences couldn't be so eagerly dismissed — and that the truth might be far more complicated than we imagine.
