Note: In illustrating a total lunar eclipse we used a bit of animation that didn’t portray Earth’s umbra and penumbra accurately. To see a graphic that accurately depicts both portions of Earth's shadow in space, visit www.startalkradio.net/shedding-light-on-earths-sha…

  • This is like a Harvard math professor explaining why 1+1 doesn’t equal 3 to a bunch of adults.
  • @arealmench
    If the Earth was truly flat then the flat earthers would become round earthers.
  • Imagine how embarrassing it would be for our whole species if aliens came to Earth and found out that, even with as advanced as we’ve become, some humans still argue about the shape of their own planet
  • @billd4056
    It's frightening that there's people who actually believe the earth is flat.
  • @MRtodd-8287
    The only thing flat earthers fear is sphere it self.
  • Oh, Dr. Tyson, when you said that our education system has failed to teach our children how to think and learn, it hurt my heart. I actually quit teaching a number of years ago because the system is so broken. And the fact that people are just pulling “facts” out of their @$$ is why we have so many problems in this country now.
  • @Enjoymentboy
    Trying to argue globe earth with a flat earth believer is an exercise in the old saying of "never try to fight a battle of wits with an unarmed person". The single most common argument I have seen flerfers use is "It doesn't make any sense to me". That alone should tell anyone everything they need to know.
  • @MrAlexanderLang
    Don't touch flat earthers, i want a future where these people exist, compared to them i look like a genius.
  • @martas9283
    I wish I'd had science teachers like Neil
  • @Brandon84J
    I love the energy Neil brought to this interview. Cheers my dude
  • @Bobert27
    Police: sorry sir this parking is only for the handicapped Guy: the earth is flat Police: oh my bad sorry sir
  • As Einstein was quoted as saying. "two things are infinite, the universe and human stupidity, and I'm not too sure about the universe"
  • The fact that it's 2022 and they still don't have a model proves the earth isn't flat
  • @Spazzsticks
    Flat earthers be like: dont believe anything they tell you, be a skeptic Also flat earthers: instantly believes anything they read on facebook.
  • @fu3g
    i love all the totally natural and definitely subtle cuts that happen mid thought throughout the video. u can clearly see how his thoughts flow.
  • @allynevans6
    The fact that the moon appears upside down in Australia should be enough to tell flat earthers that its not upside down , you are standing upside down lookin at the moon from the bottom of the round earth looking at it . And that dreaded gravity thing makes it all possible .
