 We have some big news from the North American Nanohertz Observatory for Gravitational Waves. They've announced the first evidence for expected low-frequency gravitational waves that were likely generated by the collision of supermassive black holes. Yeah, it is a supermassive deal, if you may allow me to pun. Basically, we just have a brand new way of looking at space. For the last 15 years, we've been using radio telescopes at complete opposite ends of the Milky Way to create a giant gravitational wave detector. Basically, when a gravitational wave passes above or around a pulsar, it kind of changes the rate at which it flashes, and we can measure that. And the hope is that we can detect gravitational waves that happened milliseconds after the big bang. So it's a pretty big deal.
