The Interstellar Medium and Pulsars

Pulse arso can actually be used to study the interstellar medium. It it's hard to tease out the specifics, but they think they're detecting the mergers of supermassive black holes. And you just imagine they're like, they're like radio boies floating on an ocean. They're ly going up and down as the waves are passing them. From our perspective, we see the pulser shift a little towards us, then a little bit away from us. But you're actually seeing just the ripples of the universe. Incredible. Its like watching soname move across the ocean. Umye, thats that’s the perfect, perfect description. Yes, absolutely.
