The thousand-plus physicists of the Advanced Laser Interferometer Gravitational-Wave Observatory rushed to decode the space-time vibrations that rolled across the detectors like a drawn-out peal of thunder. Thousands of astronomers scrambled to witness the afterglow. But officially, all this activity was kept secret. The data had to be collected and analyzed, the papers written.
