    I love that Stephen seems genuinely interested in promoting science and intelligence.
  • The mouthful basically means that everything always actually moves in a straight line - gravity doesn't *attract* anything, rather, it is able to warp that straight line into what we call a curve.

    “Space time is a four dimensional Hausdorff Differential Manifold on which a metric tensor is imposed that solves the Einstein Field Equations, and that metric tensor gives rise to geodesics and objects that are not experiencing any other force move along the geodesics described by that metric!” Holy crap that was a mouthful!
  • @dangleason9023
    Finally a phrase to tell the general public how little they actually understand.
  • @ClwydEnComu
    Bloody love that Stephen puts science and non-cinematic arts right up there at the front of his show, brilliant host. Wish we had more emphasis on culture and knowledge in general media.
  • I'm glad Academics are getting more shine, so we can stop making stupid people famous.
  • @QuantumBraced
    I like that he has scientists and inventors and leaders and other intellectual celebrities in. How cool an idea to honor Einstein and special relativity!
  • @silverfox1754
    That 30sec explanation took me 3 years and a degree in physics to understand 😂
  • @brennbeez
    "it's up to you man, go nuts." Is that what the gods look like when they're creating universes?
  • @Pfromm007
    Albert Einstein says that space-time is a four dimensional Hausdorff differential manifold on which a metric tensor is imposed that solves the Einstein field equations, and that metric tensor gives rise to geodesics, and objects that are not experiencing any other force will move along the geodesics described by that metric! throws punches

    I FUCKING LOVE that Stephen is sharing science knowledge with us !!!
  • @danielsmith1202
    I love Brian Greene soo much. He’s so passionate and seems to love teaching, he’s like a kid with a new toy. We need more reverence of figures like him and not celebrities that contribute nothing to society as a whole.
  • @ashwynn4177
    Wow that stopping of water flow of dropped bottle is the coolest thing I've seen. Just that one short demonstration opens up a whole vista of understanding!!
  • @dizzy-117
    I just love, when someone is hyped about something. I'm not that much into science myself, but if someone starts to tell me about something science-related and he just seems as happy as this guy, I'm really starting to get interested.

    Newton: I'll leave it to the consideration of the readers Einstein: Hold my moustache
  • @seanp4644
    I'm actually really happy that Stephen asked that last question, now I have more Wikipedia pages to read xD
