Astrophysicist Janna Levin, PhD, is asked to explain black holes to 5 different people; a child, a teen, a college student, a grad student, and an expert.

Special thanks to our host Janna Levin who’s literally written the book on black holes

‘Black Hole Survival Guide’

    1. Child 2. Teen 3. College Student 4. Grad Student 5. Expert 6. The Black Hole (hidden boss)
  • @milkshook11
    i like how once she gets to the expert it becomes more of a conversation rather than a lesson
  • @StealthyDead
    That teen is wise beyond her years. "I know more and less." That is a statement more true than she realizes. The more you know, the more you realize you don't know.
  • What I love about this vid is that she didn't just explain a black hole in terms each of them could understand, but what she actually did was to elevate their understanding of a black hole's mechanics and behaviours. She left each of them basically wondering "How and why did I not already understand this until now?". That is a true teacher.
  • @PeterNooteboom
    "I know more and less" is such a profound statement that so many people have trouble realizing.
  • @bradderrs6221
    the expert: "i wish we could make a black hole in a lab" me: please don't
  • @mkeerkens
    I think the child level is still too complex. You can't use words like "thermonuclear" when describing a black hole to a layperson, let alone a child. My dad's a nuclear physicist and I am always having to tell him that what he thinks is a very basic explanation assumes someone has a core knowledge of physics.
  • @americano451
    She is so good at explaining. I love how she never dumbed anything down for anyone. Even for the child and the teen, she didn’t act like they were incapable of understanding big words and explanations. But every explanation she gave was easy to understand.
  • I thought I was an science geek but after hearing this I'm on the level of a child.
  • @HiDefOuch
    Kudos to that kid...he was really sharp with picking up on that explanation really fast.
  • @AAR9AV
    The joy you experience while having a conversation with a person who has the same interests and level of understanding, reflects in Dan's smile.
  • @sarasasa_
    Being able to explain such a concept to different people using different words and complexity clearly shows that that person really knows what she is talking about
  • @RosiePosieBabie
    The first kid had such a great understanding. I don’t know if I even got it and I’m 23
  • @bridiemcclure
    It's funny because I know the college level ones quite comfortably and all, but it was the most basic foundation explained to the child that got me thinking the most and changed my perception of black holes entirely
  • Janna Levin PhD is a great teacher. She can explain simple concepts simply, & also introduce complexity in a way that's exciting rather than intimidating. Her enthusiasm for & interest in astrophysics is contagious.
  • @Aspett0
    8:46 "I know more AND less"... that was a very articulate way to explain the process of learning about anything.
  • @mark-ish
    Jude is clearly a well read/taught child. Showing great potential!
  • @andrewein3090
    Her: explains black holes to the 11 year old Me, an 18 year old, having replayed the 11 year old segment twice: “okay okay I think I’m getting it now”
  • The black hole battery thing has to be the most mindblowing thing I've heard in a while, every segment of this was great and I only wish it was longer
  • @brianna3275
    I love that she was able to explain beautifully on every level, without talking down to anyone or being condescending
