Scientists at LIGO have detected gravitational waves for the second time ever.
This is exciting news as it signals that the first detection wasn’t merely a fluke but that we are in fact on the right track to interacting with such phenomena regularly.
What is a gravitational wave? It’s a literal “jiggle” in spacetime caused by a dramatic event like the collision of two large black holes.
