We knew that the James Webb Space Telescope would find interesting stuff, especially about the mysterious early times. For example, there are hints that the galaxies we’re seeing are brighter and more regular than expected given the short amount of time they’d had to grow. Well, perhaps no one was expecting that we’d find a completely new type of star—one mostly made of and powered by dark matter and shining as bright as an entire galaxy. Which, by the way, might help us explain those pesky giant galaxies.

    Astronomy 50 years ago: Stare at tiny dots until you see enough to learn something. Astronomy today: Stare at nothing until you see tiny dots.
  • @baconcatbug
    Matt is so OP he travelled back in time to give us the upcoming episode on Dark Stars early.
  • Its crazy that John Mitchell had the idea that stars were so big that their gravity wouldn't allow it's light to shine in the 1700s what a under rated astronomer!
  • @William1w1
    Just looked up and read about John Michell. Guy needs more recognition! He predicted black holes in the 18th century and actually conceived of and designed the apparatus for the Cavendish experiment but died before he could carry it out, and then his friend Cavendish finished the work.
  • @JollyFuchsia
    MASSIVE appreciation for the visualisation team. Every video I'm flabbergasted by the quality of these animations. 👏🏼
  • @robfenwitch7403
    The real Matt O'Dowd would have said "How do you think I survive so long, out here...in Space Time".
  • @Fruhmple
    The Webb telescope is awesome. Can't wait to see more discoveries!
  • @Mysterios1989
    I also like the theory that these kind of stars are black hole stars, so that the pressure in a young universe was too great for the explosion at the creation of a start to push the gasses away, as it happens in modern star systems, but that they stayed close to the star, force feeding it with more and more material until the core collapsed into a black hole while the exterior still remain a star, force feeding the star-corpse to grow bigger and bigger while the radiation of the black hole keeps the star from completely collapsing into it.
  • @TJSaw
    What I love about the universe is that the more we find out, the less we know.
  • Another exceptional PBS SpaceTime episode. This is one of the best or possibly the best physics short form series out there. The density of information is In each episode astounding. Thank you for providing content that continues to push and often exceed my limits of comprehension ability. It's crazy how we evolve over time. Concepts that pushed the limits of my comprehension ability a couple years ago, seem easy to understand to me now. Thanks to PBS SpaceTime, there is no risk of me being left without mind-bending comprehension limit challenges anytime soon.😊 Wonderful job, everyone.
  • @mishie618
    I’m always extremely impressed by how you are able to communicate this type of information to the common person who is not a physics student or physicist… enough for someone who is not to be able to understand and follow along. It’s why I love this channel. I’m absolutely fascinated by all that is quantum physics and mechanics as well as astronomy and physics as a whole. Thank you for making it easy enough to follow!❤❤❤
  • @cacogenicist
    It's an attractive idea in its tidiness -- dark stars -> really big black holes --> quasars --> modern galaxies with SMBH cores
  • @philipmurphy2
    PBS Space Time always has top quality Space content, That is for sure.
  • @TheSpaceLibrary
    This channel keeps delivering incredible science content, huge well done to the whole team!
  • @FredDufresne
    Damn, Matt really is a master of space time, he went back in time to make an episode about dark stars just to flex while answering a comment.
  • @seanmortazyt
    we are so lucky to have such high quality programs available to us at the push of a button, anytime, anywhere… thanks pbs team!
  • @spidalack
    Queue people thinking this will make scientist panic because they were wrong about something. Queue scientists being super exited because they were wrong about something. Awesome explanation. As always, thanks for your awesome work.
  • @mediawolf1
    There's a bit of handwaving around the step where normal matter is finally affected. Any particle that a dark matter particle can annihilate into, has to also be a particle it can interact with. So somehow there's a chain of interactions that connect dark matter with normal matter. This whole aspect could use more explanation.
