    In the framework of the largest string theory conference in the world, Strings 2019, Science and Cocktails organized a special event at Flagey in Brussels. We were sipping cocktails in the art-deco building with string theorist and science superstar Robbert Dijkgraaf as he told us all about the fundamental laws of Nature. Afterwards, cellist and composer Benjamin Glorieux performed a musical piece together with invited guests especially commissioned for the occasion, while live-video artist Klaas Verpoest accompanied them with his visual magic.
    What is string theory? What happens to stuff that falls inside a black hole? What are the fundamental building blocks of space and time? Did Nature have any choice in picking the fundamental laws of physics? What is the role of mathematics in physics?
    This talk by professor Robbert Dijkgraaf was recorded on 13 July 2019 at Flagey in Brussels. For more science lectures with dry ice cocktails and live music, visit:

      I don't know - it's not that good a presentation, in my view. Too many pretty pictures here. I prefer something a little closer to how physicists actually work. Presentations by Fyneman or Susskind or such like.

    A wonderful presentation. I wish my dad had lived to see the internet and the wealth of knowledge that it can disseminate. He was an early nuclear physicist who revered Einstein, Feynman and Hawking (and I am sure many others in the field). He would have loved this. Thank you.

      @Robin DJW I see. Well just wondering cause I knew of a guy that was a nuclear physicist and this was in the mid forties, in his retirement he went on to record Lynyrd Skynyrd one more for the road album and Allman brothers band.

      @Jeffrey Nolan My dad embodied those philosophies, and certainly walked the talk. He was a lovely man who liked people. He would also have been horrified at many behaviors we see today. He was born in '25, and I was born in '52, but same generations, certainly. My daughter teaches college math, and I believe (hope) I have passed some hint of all those qualities to her.

      @Terry Wyatt He loved music, certainly, especially jazz. But he did not have anything to do with band recording. He was a very low key, laid back, friendly sort of guy.

      Did your dad have a passion for music? There was a fellow in the development of nuclear tech early on that went on to record a lot of bands who were iconic legends after he left the project.

    This was a great lecture! With a tribute to Hawking. I am not a a scientist but I do recognize some of the theory's mentioned here. As a child of 10, I was walking on the pavement of a street, to school. I did wonder then, if I cross the street now, and go walk on the other side of the street, will it have concequences later in my life? So, imagination is really a part of science. Without it, we go nowhere.

    Just when I was thinking I have seen too many of these videos that explain the history of cosmology, this one puts its all together in an absolutely ingenious and comprehensible way. I found myself screenshotting his gorgeous graphics that put so many of the concepts into immediately graspable form.
    But then I see he's an artist as well as a scientist, and understands the basics of music as well.
    I think that's really what it takes to be able to put this stuff together.
    Fabulous presentations, Dr Dijkgraaf!

    Mind-blowing piece of lecture. Created so many aha! moments - although I got lost in the last 25% of the presentation (string theory). I do have a silly question though - if the Universe is expanding, what is it expanding into? There must be space outside the universe that is not filled by the universe today. But if there's space outside the universe, that would also be part of the universe, since it is 'everything'. Or is the 'expanding universe' just creating 'space' out of "nothing"? This kinda relates to "what existed before the Big Bang". Will appreciate any answers.

    • 😳
      😳 18 days ago

      here's what I think. I think if you where to zoom out of the universe and see everything there is , you're seeing the 4th dimension . so maybe it's not expanding into anything but simply exaggerating the boundary between the 3rd and 4th dimension... or I'm completely wrong about this 🙃

I will watch and listen many times to this and allow my mind to expand to understand more with each re-view..Thank you so much for this presentation, Science and Cocktails and a very Happy Thanksgiving 2021 (in 2 days) to all whom celebrate.

      Ah but are you sure your mind is expanding? Perhaps it's just being distorted by the imput of all these novel thoughts? and the distortion is not dimensional but requires the time it's taking to absorb that information to vary so that your understanding of the information belongs in a different dimension. Personally I think Hans Christian Anderson saw this whole conumdrum in the correct perspective.

    I love science. I do have a different explanation for the beginning of all things from a much smaller space than now exists, but I do think it’s odd that the speeding acceleration explains what I believe to be final singularity.
    Assuming that it is a decrescendo of the original crescendo, that is.

    "We have now a full understanding how from these initial conditions the universe was formed." Given the fact that we can only see so much of all existing frequencies with our human eyes (and brain) this is a very bold statement to me. We humans didn't even start to study - left alone understand fully - the "I" that is making such a statement or doing the studies. So not having a clue about who is looking through the lense of the makroscope while studying anything "out there" how can anyone make a statement about fully understanding xyz, if not even the "I" is a fix parameter? I know that I don't understand the miracle of life and I assume it can't be fully understood in our current state with the 3D-human-mind. A wise man once said: That which the scientist is looking for when looking through a microscope is behind the lense looking. Or as Mooji puts it to the spiritual seekers referring to "the higher Self": The place you are looking for is the place you are looking from.

    I’m a Marine, so I have a grasp of exactly what it takes to destroy something. I love science & physics and am intrigued by the possibilities of time travel-which leads to my minor point. If YOU travel back in time, what you do now/then/whenever will not eliminate or alter my path now and up to this point. Oh, hold your arguments, as time will eventually prove who’s correct. I do not believe a person’s presence manipulating the past, can make my present right now change because for me, my history is sealed and has already happened. The best one can do to convince me is that another time path in another dimension would be created. Maybe my future can be changed by you going into “my” past, but you cannot change my past nor destroy me now, as you don’t have the “power” required to effect me today by visiting my past and screwing with it. E.g. killing my mother as a baby, will not cause me to “poof” disappear the moment you perform that act. Killing Hitler as a child would not reverse everything I’ve experienced up and to this point. Now, what it would do to my future? 🤷🏽‍♂️

    In it's ease of understanding (not that I claim to :) and thread, it is reminiscent of Bill Bryson's, "A Short History of Nearly Everything". Which this lecture seems to pack into under an hour. However should one be interested, Bill fleshes these discoveries out, by introducing you to the characters and their insights, again in an equally digestible and often comical way.

      Stuart, I couldn't agree with you more. As I read your comment, I had a strong feeling that you have or will have, knowledge to share with as much clarity and simplicity as Dijkgraaf. I am just beginning to learn about quantum physics etc. string theory and although much went over my head, I KNOW it will all come together by 'Being brave, being determined and finally overcoming the odds" as referred to by Stephen Hawkins at the end. :)

    A fascinating presentation. At 10:30 there is an elegantly simple explanation of Einstein's view of the Big Bang theory. Worth a look if you don't have time to see the entire presentation. Also at 30:08, Dijkgraaf presents his fascinating visual depiction of "empty space."

    • Lepi Doptera
      Lepi Doptera 8 months ago

      Yes, that is fascinating, but so are Superman movies. And just like Superman movies what he is showing there is a complete fantasy. That is not how empty spacetime behaves. How do you know? Just look at the nigh sky. You can see light from stars millions of lightyears away in all clarity. With the right instruments you can see through billions of light years worth of spacetime. If it was really a quantum soup, then what you would see is a soup. Indeed, you couldn't even see as far as your own toes. The virtual particle model that leads to such misunderstandings of spacetime is just an unfortunate mathematical consequence of our most often used quantization procedure (Feynman's path integrals). It's the same thing that leads to a calculation of the vacuum self-energy that is many tens of orders of magnitude wrong. If the vacuum was filled with all this noise, then that calculation would probably be halfway right, actually.

  • Dr. P

    Great lecture. The thing that boggles my mind, is that rather there being multiverses adjacent to each other, what if there are multiverses within the same space. Physics we comprehend is unique to our universe. What if there are different laws of physics in an equally shared space. I think that this could be the case but there is no way to prove it to my knowledge. It seems like there are a lot of things that they are discovering these days in physics and cosmology that would support such findings --for example dark matter, space and quantum physics...

    A very good expose on the nature of things that we know (science) and of things yet to be known (imagination).
    The nature of string theory however and it’s potential application was barely covered.

    My cat has it's own version of 'string theory' and it is likely more provable . Nice video , entertaining in a surrealistic way .

    When light travels far enough it decays into particles known as string and these particles will start to collect and depending on the amount of energy left in them at the point of collection is what determines the form the collection will assume either biological form non biological form or energetic form the light regenerates itself

    Actually actually I found it quite actually interesting actually to hear someone who has put a lot of perspiration and to figuring this out I was raised by a writer and that was when I understood that writing is 10% inspiration and 90% perspiration I can remember going to bed at night and hearing a typewriter clicking and clacking away and getting up in the morning and hearing the typewriter clicking and clocking away and that was in an old Underwood typewriter not a word processor or electric typewriter it was the original fingerstrong Armstrong typewriter my mother was obsessed as our the writers of old and I'm sure that these physicists and mathematicians which are are what physicists are to some degree have got to be obsessed the original ones anyways cuz nowadays it can all stand on their shoulders and sound beautifully intelligent when actually actually it's actually you just have it all memorized actually speaking of course I have never been one to be too obsessed about anything except or maybe myself I'm a true narcissist I hear these people the physicists and the authors and everything speak and I wish I was them but I'm not actually I'm just a fool and now I'm going to get back to the documentary

    The concept of death in a zone with no time fascinates me. Everyone you ever knew would be there, whether they were dead or alive when you passed. On top of this it would be impossible to look down on earth in a time frame from when you died without asking yourself which earth? The instance you died opens up for infinite possible earth's to exist. Ones where your friends and loved ones even died at the same time as you. Weird concepts to think about for sure

    Science is just something I like to try to understand as a nerd. I'm not hardcore but I feel I know a lil more than the average guy. This presentation was SO well done. It was clear, easy to follow, and at no point did I lose interest or get lost. As a matter of fact it gave me a better understanding of what I thought I already knew, yet, have me more questions of the possibilities. What a remarkable time we live in indeed. Thank you for this. Wow!

    I just came across you video in Jan 2022. The only way I can thank you for such a great presentation is to share. In 2014 in the Journal "Water" I was given credit for discovering a new form of Life Energy. This energy appears to be similar to Life Energy in every way except it exists independent of life. The math it is based on is Einstein's Energy equation predicting negative entropic energy and those are the properties that were seen. Years later there is now much more to share and new applications with plant life. I want to share it with you.

    If you sent something with more mass in front of you at a higher rate of speed, could you travel through its warp at a faster rate of time?
