CERN70 Live: The case of the (still) mysterious Universe

Over the past 100 years, physics has advanced our understanding of nature to an unimaginable degree. The fundamental laws governing many of the building blocks of the Universe have been discovered, and the evolution of the Universe can be traced back 13.8 billion years to almost the beginning: the Big Bang.

Physicists have built laboratories spanning tens of kilometres to study nature at the smallest scales and sent telescopes into space to gather information about different forms of matter and energy. How much do we still not know about the Universe? What mysteries remain to be solved?

During the event, you will be taken on a journey through space, time, and the history of ideas in modern physics: what we know and what we do not know. Through the eyes of renowned physicists, you will be exposed to some of the greatest mysteries of the Universe. Why is there more matter than antimatter? What are dark energy and dark matter? How can we unify all the forces? What future experiments will reveal nature’s deepest secrets? Is the Universe made of vibrating strings? Is the Universe holographic? What are black holes made of? Could there be more than one Universe?

Prepare to be accelerated into a mind-boggling physics experience at CERN. Join us for this fifth public event, held in collaboration with the Strings 2024 conference, celebrating the Laboratory’s 70th anniversary.

Live performance by the Orchestre des Nations of "Open Questions", an original music piece for string orchestra by Domenico Vicinanza based on the sonification of scientific data, under the direction of Antoine Marguier.

If I had Shiraz Minwalla as my Physics /Theoretical Physics Professor or even Kindergarten teacher, I would have fell in ❤LOVE❤ with science and math and chosen to become a Scientist. I love his passion.

[Visualatrix]

While I have a basic/incomplete understanding of the subjects discussed, I am truly impressed by the dedication and extensive research that has contributed to its development. It fills me with a sense of wonder and gratitude for the advancements in technology we currently enjoy, as well as the promise of future innovation. Despite the challenging circumstances and widespread miscommunications in the world, this helps me choose to remain optimistic. Loved that music pieces where included.

[Exngo]

Fantastic talks. <3 Thanks for sharing so high level of compitent people in 1 video. Music peaces - also great and outstanding.

[litttoe]

Amazing truths shared! I think the biggest battle physicists face is our own linited understandings and systems. Reality will always be there when we come back to it.

[lisamuir]

No doubt this year is wierd, interesting and much more to come. No time stamp needed.

[scenFor]

From the viewpoint of gravity there is no surface, just quantum steps of information movement.

[gypsycruiser]

Intense light causes pressure waves.. and will be detected. The Higgs Boson was prematurely celebrated…

[dominiccordova]

Can you imagine Minwalla and Nima Arkani-Hamed in a colloquium? The intensity level would warp space and time.😂😂😂😂😂😂

[GordonShuffell]

They can build and operate one of the most complicated machines in the world and make amazing scientific discoveries but can't seem to manage the audio video

[VALERIAN]

Que hermoso, como me encantaría estar ahí 🖤

[christopherchilton-smith]

Cern fears the power of the Wave Conjugation!



🤣🤣🤣

[ryanchicago]

How can you explain the existence of black holes, when the graviton, itself, must obey the maximum speed of light "c"?

[merlepatterson]

If we could build a light ring which was approximately 186, 272 miles in circumference and set it to flash at truly synchronized 1 second intervals (on for 10 msec off for 990 msec) for the entire circumference. What would it appear to look like from an extreme edge or from the geographic center? What would happen to the flash rate if the ring were set in rotational motion at light speed from a central observers perspective?
My hypothesis is that the flash would appear to progress from the local observer at the extreme edge perimeter to the opposite diametric point but from a center perspective it would flash in unison for the entire circumference.
Also, the flash rate would remain constant if the light ring was set in circular motion at light speed because the effective speed is zero to the central point for GR purposes and no time dilation would occur to the flash rate.

[Jeff-nine]

Why don't planets fly into space when they reach perihelion?

[saingsodanin]

I start to question why universe is so big, what make them so big 😅

[IBUUBME]

Maybe the quarks break down into something else, then that breaks down, then down down down into infinity particles 😮😳😂

[prometheus]

What about emergent gravity or entropic gravity as a dimensional field, to explain the way matter behaves in space time and the flow and structure of space time itself as quantum-entangled dimensional quantum and entropic pressure? If that is closer to objetive reality a reductionist model of gravity in say the idea of a graviton is a dead end. What implication in particle physics points to a unifying principle of gravity and quamtum mechanics imply that gravity must be a particle field? Not a thing. And entropy is a possible candidate for anti gravity through dark energy beyond and at the point of the cosmic horizon. We cannot be sure there is no anti gravity, there are possible models that can account for anti gravity and asymmetrical variances of classical physics, at sub atomic scales. A positive quantum pressure that exists in asymmetry to quantum fields, of negative quantum pressure or quantum gravity. Such concepts exist in higher-dimensional models of gravity and dimensional fields, that won't require any new particles. Such as holographic principle theory or emergent or entropic gravity concepts. Particle physics is useful in understanding particles but should we assume it can unify general relativity with quantum mechanics?

[WisenCynical]

Such a fun watch!!!! Tell me, why is science so elitist? Anyways.. (I am a big Hooke fan and ever await my fall from grace). Has gravity ever been explained as an average of space/time across a 4D space of 3D attractors and repellers? Atoms are no slouch as a dialectric across mass 3D space. It is friction tied to space/time, entropic to atoms. Perhaps it has been in your equations all along, as compressed gravity in isotopes. Just a silly thought.

[GrLuSac]

I cried that Terrence Howard was not invited when mentioned mathematics and vibration relation not addressed.

[tonibat]

53:50 Schwatzschild proved them wrong.. and Einstein didn't like it.
Disproving Einstein at your own risk 😂
