The discovery of gravitational waves has been hailed as yet another vindication of Albert Einstein’s theory of general relativity, unveiled a century ago. Indeed it is: among the theory’s predictions was that violent events in the universe involving immense masses – such as the collision and merging of two black holes – could set the fabric of spacetime ringing, the ripples spreading across the cosmos and stretching or squeezing space as they pass.

Experiments at the Advanced Laser Interferometer Gravitational-Wave Observatory facilities in Washington and Louisiana have detected these distortions, and it’s a tremendous, exhilarating moment for science. But it’s been barely noted what a deeply strange, perhaps unprecedented situation this is too.…  Seguir leyendo »
