Surfing space-time — gravitational waves
Asymmetric gravitational interactions between two bodies produce gravitational waves.1 Such perturbations in space-time are so small that only the most massive interactions have been detected by LIGO, which uses laser interferometry and is “the largest and most ambitious project ever funded by the NSF.” While there was speculation about gravitational waves prior to Einstein’s theory… Continue reading Surfing space-time — gravitational waves
