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:

Funny how people even today are locked to Einsteins equations keeping them as the truth without searching for other solutions. Equations explain the things we can understand only. Universe is full of phenomenon which cant be explained by anything we know today, we only guess because Einsteins equations are incomplete.

Hey fans! What's the big deal mentioning "The Big Bang" here? We have known for over 25 years now that it was just a "Big Dud": It never happened! It can not happen. Articles and books on this "did not happen" event have been signed by over 4,000 physicists!

It is incredibly feeble minded to take theory and speak of it as if it were fact: 1) The microwave RF radiation is NOT an artifact of a Big Bang. 2) The theory of (expansion / contrition) has much more supporting data than the BBT.

There's just one problem with the big bang theory..where else in nature does order come out of chaos? If you set off an explosion under a pile of bricks does it fall back to earth in the form of a house? No, so how do you explain how a mass of debris becomes a planet..then that planet finds an orbit around a sun..then develops an atmosphere and then life all from a giant explosion? You cannot get order from chaos..order comes from God. A universe can't create itself any more then a brick house can throw itself together. No God, no beginning..know God, know beginning.

Of course, I totally agree. However, one or 2 blocks of humans can’t fight it. It has to be done in numbers, than we have power. But too many would rather tolerate & do nothing. Which is only leading to worsening conditions.

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.

Lies lies and more lies. The math breaks down for the big bang. All the energy from the universe would have had to fit inside a singularity - a single particle containing infinite energy - absurd and impossible. No detection of dark matter or dark energy. This guy is like a preacher pushing religion on the ignorant masses.

BIG BANG IN QURAN the whole heavenly universe and the earth were (all) joined together as one unit, and then We split them apart? And We originated (the life of) all the living organism (on earth) from water (Surah al-Anbiya Verse-30) SPACE EXPANSION INFO IN QURAN And We built the heavenly universe with great might. And surely, We are expanding (this universe) more and more.( Surah Dhaariyat Verse-47) ا SUN IS NOT ONLY ROTATING ABOUT ITS AXIS BUT IS ALSO MOVING TOWARDS ITS DESTINY- QURAN And the sun is constantly moving forward towards its appointed destination. It is a measure fixed by the Almighty, All-Knowing (Lord). )(Surah Yaseen Verse-38)

He touched on the basic vital point, black hole, and then jumped off the subject. Totally convinced time has speeded up, hence we are running out of time, dark matter is expanding and we are in a bubble that is squeezed tighter and tighter until finally it will burst with force of dark matter. The frequency has changed.

So I have a little question... If intelligence can be a subject development within our 'discovered reality'; reasoning human beings have been developed within this observed universe.. then, why couldn't there be intelligence behind our observable 'veil'? On a higher plane? What if it's intelligence(s) that have been developed or come to exist on the extreme macro level, beyond our observability.. that is influencing or defining the quantum movements within our observable reality? What if there are infinite layers of intelligence and influence? Imagine intellect at at least the same or likely a higher (possibly infinite) complexity of our brain to be defining or at least influencing our reality.. And we are prodding with our measuring equipment trying to fathom every movement every moment.. Isn't it a little funny? I hope that was a nutcracker..

Oh I just loved this..I just approached it with an open and relaxed mind and allowed the information to flow into my brain. The presentation is fantastic along with the visuals for extra understanding. I am in the early stages of discovery and I absolutely 'second' the comment below by Stuart Greene, one month ago. 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.

Maybe space never respond to gravity. Maybe we float (4% of visible matter) in space between universes. Since 4% is not enough matter to become universe , dark matter is helping to bring visible matter into galaxies and through trylions of years black holes will get rid of the matter into pure energy. Maybe something went wrong during Bing Bang and antimatter didn’t destroy matter 100 %, left over 1 particle per million become visible matter and temperature in space went up from perfect O kelvin to 2.73 Kelvin ( like virus) that don’t belong in the perfect empty space.

UnShapingTheEarth Před 14 dny
Idiotic. The first words out of this guys mouth is reifying the absence of matter. The absence of light is darkness, the absence of light behind an object is called a shadow. It is nothing, it does nothing, and it cannot be acted upon. We act upon matter, matter has properties and can bent, broken, beaten, etc. You cannot bend, break, or beat a shadow. This is the joke in the famous movie “Peter Pan”. If children can understand that you cant “do” things to “things” that do not exist, then why cant this supposed intelligent guy? Space is the absence of matter, it cannot be bent, it does not and by its lack of existence cannot have the attributes of matter put upon it. Matter exist, space does not. Space is the area in between. The limits of our language make it to where we have to explain these things. But again its not out of children’s comprehension. Space was never solid or rigid, steel buildings can be solid and rigid, space is not matter therefore it cannot be solid nor rigid. Hopefully someone who reads this still remembers common sense and understands these basic basic things.

How I understand... the universe exploded many times before and will after us. The tears in space time are the scars on the universe they made. Black holes are the key. The big bang happens because of a "trop plein" Boum !!! As mater is thrown everywhere, some chuncks don't have a chance to expand and their mass creates the first black holes holding and shaping our new universe, grabbing all matter in its nearest vicinity and voilà a galaxy. Doing so of course time also expands. Black holes are the bringers back of this explosion to its original point. Mater, energy etc. If you notice, massive black holes are at the center of most galaxies. Some smaller, roaming, or attracting will encounter one an other, and grow bigger. Throwing all matter it encounters back to the original point, going back as well in time. The universe will not and cannot expand eternaly. Because of this dark matter and dark energy holding it together. Roads for the black holes to take to lead to one an other. In time black holes will have consumed everything, until they all unite into one, once again. The matter too hard to hold because its mass is higher and compressed wants to escape. And BOOM here we go again

The words Time and Space both have multiple meanings. Time is both the dimension of change (hence ‘rate’) and the collective ‘flow’ of change (the only empirical evidence of ‘time passing’ is change). And Space has several (related) meanings. A space could be a gap e.g. in a car park, for example. Space also refers to the dimension of position, i.e. the three vectors of xys axis. Or Space might mean ‘everything not on earth’ as in ‘outer space’. And sometimes Space refers to the entire known universe….which we know to be expanding But science is so often not specific when it uses the words. It liberally, lazily conflates these different meaning of these words. In the context of spacetime, space is the dimension of position, time is the dimension of change, so spacetime is the dimension of changing position aka motion. Dimensions are abstract. Dimensions are calibration abstracts that we overlay an aspect of reality in order to measure and index that piece of reality. Time measures change, hence rate (time is abstract, change is real), space measures relative position (position is real, space is abstract, and spacetime measures/indexes relative motion. Motion is real, spacetime is abstract.

I loved this, it was great. I wish though, that you would have said a bit more about that Flemish tapestry that had something in the corner that suggested how timespace looks or can be visualized. Does this specific tapestry have a name? Is it famous? Can you say something more about it, or how I can find out more about it? Thank you..

ºIf we are exploding half a million miles an hour through space or even one mile an hour, in an ever expanding universe than the stars should have changed their relative positions in the six thousand years that we've navigated using Fixed Star Location. But they haven’t. Stellar drift is a misnomer. Polaris is still the North Star. All the zodiacs still look like what they were named after some six thousand years ago. The great pyramids of Giza are still perfectly aligned with Orion and Orion having twelve independent stars should not still be looking like an archer. And Haley's comet knows where to find Earth every seventy-five years in an ever expanding, chaotic universe ? There are over two hundred stars in the constellations alone and if they haven’t moved in over six thousand years then they never will. It’s practically written in the stars that, “The Earth is stable and cannot be moved.” 1 Chronicles 16:30.

I havent watched this....but at 4 am the other day i was jolted awake and wide awake yet disoriented until i realized it was sunday and i didnt have to work. I call my mother all day. Her failure to answer let me know she went back home. Then when i travelled out of town to my house she lived in there was a message on the landline machine. I returned the call to Jen. Jen said, it was 4am when she left and she is pointing to her heart. Jen said her transition was very fast she is already doing things. I asked who met her and typical of my mother she said she doesnt want to say.....and then thats all i got she was off to do something else. Her "second son" just a super good younger friend handy man who found her passed for me told me he also was woken up at 4am but more gently and couldnt sleep and then had a spiritual conversation with his wife. Jen said my mom passed through my body and woke me up as a good bye, i totally felt it intensly and didnt have a clue what it was.

String theory very much based on Quran. That's why I was never a fan of big bang theory. Al Quran 21:30 Do not these unbelievers see that the heavens and the earth were an integrated mass, then We split them and made every living thing from water? Will they not believe even then? Al Quran 41:11 Then He directed Himself1 to the heaven while it was smoke and said to it and to the earth, "Come [into being],2 willingly or by compulsion." They said, "We have come willingly." GO FIGURE!!!

Time and space can't come to an end. It's beyond imagination. Time and space is universal for everyone. Everyone feels it differently. It ends with the death of a creature. When a creature is born, clock starts to count time commencing from his birth. Time stopped? No! Time stopped for him! You've a clock on the wall of your home. It has seen many deaths and many births. Time can end when space of infinity becomes zero. This is not possible. The East are made after meeting God physically. The West are made after such absurd imagination.

Black hole are not singularities at their center with massive gravity pulling inward. They are areas in space that are void of space. Created by large explosions that push space outward and then it gets pulled back into the void. Black holes should be called voids. The event horizon is the area at which the centrifugal force throwing everything out of a collapsing spinning black hole is balanced with it inward collapse. It’s just a low energy/pressure area. Kind of like matter is a low energy/pressure area in space.
Scott Bethell
Scott Bethell Před 20 dny
I think we only live in an expanding universe because of the creation of matter within space. Matter that comes from space takes up more real estate because it has less energy then space. Kinda like shaking a soda can…. The drink is space, and the bubbles are matter, and if not in a can it would expand. The universe will always appear to be expanding outward from the observers point of view wherever you are. Stars are the matter making machines.

High priests of scientism really love equations because they can convince you of anything through equations. Nikolai Tesla in his day spoke out about these wild equations that were not based in reality. Even Albert Einstein admitted that Nikolai Tesla was a more brilliant man than he. The people who turned science into scientism are not scientists they are the billionaires, the filthy rich, the cabal who supply the research money and who supply money to the science programs in our universities they are the ones Who control the narrative from behind the scenes. If a scientist or researcher goes off script they pull his funding or they pull the schools funding. That’s how it’s done and that’s how it’s been done for a very long time.
