Einstein’s Theory About Gravitational Waves Was Just Proved Right — Again

Science, like so many other things, has tipping points. Figure out how to isolate and identify one virus and you're on your way to bagging them all. Spot a single exoplanet and within a few years, you'll have thousands. The same is true with the cosmic phenomenon known as gravitational waves. It was in 1915 that Albert Einstein first predicted that the fabric of spacetime itself could be set to rippling by a powerful enough force, but it wasn't until 2015 that the first waves were spotted.
