Kilonovas and multi-messenger astrophysics

So many media headlines today regarding the observation of both light (EM spectrum, not just visible/optical light) and gravitational waves from colliding neutron stars. Lots of visualizations. Big science in action. Here’s a sampling of headlines: Gravitational waves from kilonova collision of neutron stars discovered – The Washington Post Gravitational waves: So many new toys… Continue reading Kilonovas and multi-messenger astrophysics

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
