www.ted.com/ At the heart of modern cosmology is a mystery: Why does our universe appear so exquisitely tuned to create the conditions necessary for life? In this tour de force tour of some of science's biggest new discoveries, Brian Greene shows how the mind-boggling idea of a multiverse may hold the answer to the riddle.

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the "Sixth Sense" wearable tech, and "Lost" producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at www.ted.com/translate

    Love his PRECISE AND CORRECT wording: ""our form of life"" , as opposed to just saying "life".

    I admire how Brian Greene is so absorbed in his explanation. It is like an adult telling children's stories to small children. :-)

    I feel so good reading this comment section😭 Some of my friends told me that I'm mad because I am interested in stuff which is not related to my engineering branch

    Brian Greene is indeed one of the greatest scientific speakers. Wheter you like his ideas or not, you have to admit, he's good at presenting them!
  • @stratogustav
    This guy is a great teacher. I actually understood everything he said, even the little details. That is a gift, not many can pull that off with these kind of topics.

    Brian Greene has so much passion, we as viewers are lucky to have him... His specialty is making it exciting and accessible for regular,ordinary people. I remember watching “ the Elegant Universe “ when i was a kid,and being extremely inspired. Its amazing the stuff he (and others)predicted so long ago, is finally coming into light.
  • Whoa, I actually never thought about how astronomers in the distant future won’t be able to observe the universe as it is today because of the expansion superseding the speed at which light reaches us. They will see less than we can and they won’t believe a word of our “ancient research”. That’s actually a frightening thought.

  • That part about future humans observing deep space and seeing nothing but darkness really hit home for me

    I am both ASTONISHED and SCARED by the capacity of reality.
  • @eclipse369.
    This man does an excellent science concert! I love his energy and dedication to forever learning!
  • @nvsabhishek7356
    Out of all the ted talks I have watched till date.. This one deserved a standing ovation the most... :/
  • @asura-2467
    To get an answer with single approach to an problem is quite difficult sometimes. But at a same time it is quite difficult to forgo that path for which u spend too much of efforts.

    Studying physics is like playing marco polo but all your friends get out of the pool and drive to Mexico
  • @Ukepa
    Brian Greene, "the elegant communicator", makes cutting-edge physics understandable even to math dropouts like me.
  • @FirstLast-nz9vo
    I loved the amount of energy he put into this talk. Made the world of difference 😉 my favorite ted talk to date
  • @thespam5330
    this guys seems to love that presentation he is doing, like he planned for months, that makes me so excited
