Exactly, and the big thing there is that these accelerations happen conveniently before the interesting events.<p>When 2 neutron stars circle each other, they&#x27;ll start sending out gravitational waves. This will start to occur centuries before they collide, but they increase exponentially until the collision happens. Today they cross the detection threshold a few minutes before the actual collision, depending on their size. If we can get that up to a few hours or a few weeks we can use this to point every telescope in the world in the right direction before the flash of the collision happens.<p>So an immediate application is simple : it gives us advance warnings of large events in the cosmos. This means a lot of instruments dedicated to studying huge-energy events no longer has to look at the entire night sky, or get lucky, but we can actually get a signal before they happen.<p>In theory, if we can get the instruments accurate enough, we should be able to detect even smaller events like a supernova. A gravitational wave should be generated a few hours before the flash.
