Published 2023-12-08
The powerful blending of theory and observation has catapulted cosmology from campfire storytelling to precision science. Brian Greene is joined by Jo Dunkley, Eva Silverstein and Nobel Laureate Adam Riess – scientists at the forefront of fundamental physics and astronomy who are pushing that understanding ever closer to the beginning of time.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

    Have zero education. Not capable of understanding what Brian Greene is talking about. I love the fact that someone could know what he knows, to me, it's like magic or religion except I know it's real. I completely admire these guys who dedicate their lives to explain the universe. I'm a gardener in Ireland. This is all I watch. I think that Brian Greene would sit down with me for a pint and not look down on me for my ignorance but would respect me for my wonder and interest.
  • "thank you for uploading these videos. Even if I'm having a hard night, I just put a relaxing astronomy video on and listen. It always makes my nights go much easier. Thank you!!!"
  • @triqpham
    Adam is incredibly knowledgeable but also very clear at explaining the information. It’s easy to understand how he won the Nobel award.
  • @coreyrachar9694
    When I was reading Brian's books back in my 20's I never expected to see him blow up like this. I'm so thankful for this window he provides into scientific topics for those of us who didn't go down that path. What a tremendous dude.
  • @bizpo2713
    Brian is a talented guide through these topics.
  • @abhijitborah
    A discussion as lucid as the great books of physics ever written. Thanks for having it.
  • @spaceinyourface
    I allways think the best scientists have the best analogies for how wrong science can be ,,it brings everyone on board. Adam Riess is brilliant.

    Happy Friday to our Beautiful universe and all of you. Everyone take a Day to learn about the place we live in. Take some time and show respect for our beautiful, magical, and astonishing universe. Looking forward to this thanks WSF and Brilliant team of people that make this happen!
  • If space-time came into existence as infinite at the beginning and has been expanding ever since, that's a real life Hilbert's Hotel example, and we're all living in it.

    and also thank you for: This program is part of the Big Ideas series, supported by the John Templeton Foundation
  • @tyeprivate2890
    I am captivated with Brian's intellect and humbleness.
  • @yaserthe1
    Thank God for this channel. Takes the mind off the madness of the world, Ukraine ,Gaza etc...
  • @marymactavish
    I love the idea of explanations being Just So stories without more evidence. Once you know what those are, the explanation is crystalline.
  • @garypuckettmuse
    Wow, kudos to the graphics people! Great visuals. And so well coordinated with Dr. Greene's explanations so that what he is saying advances our understanding of the principle being shown in the visuals. It's not easy to make all this flow so well. And of course the director is always awake and prepared. Well oiled machine and the world is a better place for this work of bringing these topics to the public.
  • @SoniSingh-fl8cf
    My wife and I are so thankful for Professor Brian Greene and his presentation of such important and interesting topics 🙏🙏.
  • Thanks so much for this presentation! Such clarity improved my comprehension where I have so struggled. Great communicators all.
  • @anitagibbs8780
    What an intro! I’m thinking these talks are almost as good as it gets. My mind loves this!
  • @simultaneity8014
    Thank goodness we have Brian Greene to translate scientists for us.

    Someone help me to understand where these events come from? When you go to the WSF site, and click on "upcoming events", there's nothing, but whenever a video is posted, you go to "upcoming events", and there it is, posted as if someone went back in time and posted it. Are these events things that one can buy tickets to and attend, or do they mystically appear in the past from a parallel universe? Not annoyed, just wondering who all the people are in attendence and how they got there. It would be fun to attend a live event.
