This is awesome! We should be able to find more gravitational wave sources and it will give us a better picture of the cosmos. Also, that we have more sources with better correlation and more information.
The best part is that gravitational waves stand out in a way that events in the visible spectrum do not, so these gravitational wave observatories will be helping find events and get them observed in every portion of the electromagnetic spectrum that we can observe. That means we'll be observing many more of these kilonovae now. This truly is a new era, as we'll now be able to use all these observatories at the same time to observe the same events, and this will yield the highest possible resolution imaging of these events, as far-flung telescopes are able to function as one really, really big, virtual one.
