What are astrophysicists announcing tomorrow?! Speculation is rife… #shorts #pulsars #blackholes

@hankschannel you’re right, us astrophysicists do know something 😉 and until tomorrow we’re all 🤐 BUT we can do some speculating. If your guess is right about this being a detection of light years long gravitational waves using the timing of light pulses from pulsars (😏) then what could cause these gravitational waves? Supermassive black hole mergers? Cosmic strings? Matter phase changes? Or even inflation of the universe? 👩🏽‍💻 I’m Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don’t know. If you’ve ever wondered about something in space and couldn’t find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.
