Dr. Becky | Newly discovered "Big Ring" mega-structure of galaxies breaks our best model of the Universe @DrBecky | Uploaded 8 months ago | Updated 1 minute ago
More about the "Big Ring", how it was found and why it breaks our best model of the Universe coming in this month's Night Sky News video for January. Subscribe son you don't miss out! #shorts #cosmology #astrophysics

👩🏽‍💻 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.

$An astrophysicist reacts to 3 Body Problem #shorts I got invited to the London premier of Netflixs new sci-fi show 3 Body Problem (created by the team from Game of Thrones and based on the books by Liu Cixin) and you know I cant turn off my astrophysics brain while I watch sci-fi, so as usual I had many thoughts while watching the first episode. So heres my initial reaction, from diffraction spikes on stars when the Universe is winking, to whether physicists would be happy or sad if theory suddenly stopped agreeing with experiments, to passing off the Super Kamiokande experiment in Japan as a particle accelerator in Oxford! #3bodyproblem #netflix #astrophysicist @Netflix Video filmed on a Sony ⍺7 IV 👩🏽‍💻 Im Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church).
