Giant Stars Don’t Follow the Rules | SciShow News

Astronomers are learning just how big early stars might have been, and how their deaths have shaped the universe. Some may have even been so massive that they skipped the whole star phase and collapsed straight into black holes!

    Hank, you need a hairdresser! New patreon goal!!

  26. Maracachucho

    The thought of an event horizon forming and the almost certain possibility of a super/hypernova happening inside of it as all the mass is compressed… that kind of blows my mind!

  27. Johnny Li

    oh, 500th episode! Is that why Hank’s hair is like that?

    Excuse me, aren’t GRB different from the “polar jets” ?
    The latter cause the former

  42. sef man

    Congrats. Im enjoying watching you grow older. Its the little things.

  45. dimezreconB4

    Scientists being wrong and having to rethink a theory? Yeps. It’s called science. No scientist is ever correct for long.

  46. Rik

    Congrats on the 500th episode! I love this channel

    I literally just finished listening to The Life and Death of Stars from Great Courses. Thanks SciSho.

  55. Carlo Dimidio

    I’m sorry, but 500???? Where are they?????? I must watch!!!

  56. gintim8

    Well done to y’all involved! Big respect to Hank for getting out of bed for the episode! <3

  57. Karl Kiefer

    Congrats on the 500th you guys! The topics you cover are fascinating to a non-scientist nerd like me.

  58. Christopher Lee

    Congratulations!!!!! and keep up the good work!!! Feels like just yesterday when this channel first spinned off of the original Sci Show.

  59. Duane Vasquez

    Congrats on the 500th. You should switch with Trace from D News on 1 April

  60. op4000exe

    Wohoo the second answer is amazing since I, a couple of years ago literally asked the question on reddit, about what’d happend if a star was in the larger excess of 1000 solar masses. As assuming lifespan goes down with increased mass, it’d be reasonable to assume that at some point it’d literally be so massive that the surface gravity of the star would exceed 1C, at which point it wouldn’t be a star, but it’d be a black hole.
    So thanks whomsoever answered that question (the scientist behind these papers), that’s one more question answered that I don’t have to think about again.

  61. Mark Duvall

    Congratulations on 500 episodes, and keep up the great work!

  62. E2qNX8btraQ3zRD6J7fc

    The gravity of SciShow’s success is so massive that…

    Man Hank really looks hungover in this episode ๐Ÿ˜‚

  73. Caliburn Creative

    You guys are great. Thanks man.

  74. Stephen Atwood

    Hypernovas aren’t fueled by overindulging in Five Hour Energy drink?

  75. Nik Milkoff

    I’m following you since it started, keep up the great work!

  76. Christel Headington

    Giant Stars,”Rules? We don’t need no stinkin’ rules!”

  77. John Harbo

    THANKS FOR BEING GREAT CONTENT CREATORS! NEW SUBSCRIPTION BECAUSE I LOVE ALL THESE VIDS!
    I’m curious to know if the Perseus nebula is is the remnant of such an amazingly cosmic “hyper nova cocoons” & if it’s gamma burst was near enough to affect the Cambrian era apocalypse?
    What do y’all think?

  78. DieWeltIstSchlecht

    Happy 500th!!! Here’s to five hundred more!!

  79. JamesT85

    Hello hank congratulations on 500

    See you at the 1000th !!!

  90. Nafrost

    Wow 500 episodes what an amazing journey.

  91. niki123489

    Congrats on 500th episode! You discuss very interesting topic and I really enjoy it!

  92. Zac M.

    Congratulations on 500 episodes! Wooo! Genuinely love this channel, I just kinda like space!
    Also the fact that early stars _could possibly_ skip the nova stage or even the star stage could be skipped and get an instant black hole is a kinda terrifying tbh. The latter mostly. Can’t really get my head round that!

  93. Ranger Ruby

    So there are supernovas. There are Hypernovas. Are there just…novas? Do those exist? I really want to know and I don’t care if there was an obvious answer that I forgot.

  94. MasterMazeProductions

    wow, I remember when you guys first announced the launch of SciShow Space! Can’t believe its been so long

  95. Luis Bravo

    Can’t wait for the next 500 episodes…good work guys and gals

  96. The Exoplanets Channel

    Perfect video to relax a friday evening!

  97. New Message

    This could easily be a TMZ video title.

  98. batmanfanforever08

    Nova = star brightens and then dims, no explosion
    Supernova = star explosion
    Hypernova = big star explosion
    Unnova = star skips explosion, goes straight blackhole
    Failed supernova = star that tries to explode, but doesn’t
    Seed = gas clouds that just become a blackhole, no explosion and no star
    [I think that’s how it works, I could be wrong. Please correct me, if I am wrong (with sources).]

  99. Kristel Jean de la Cruz

    Scientists: Hey that’s not within the rules!
    Giant starts I AM THE RULES

    The first half of this video blows and the second half of this video sucks. ๐Ÿ˜‚
