“We don’t have enough knowledge to precisely calculate what is going to happen, and so we assign probabilities to it, which reflects our ignorance of the situation.”

About Brian Cox:
Brian Cox obtained a first class honors degree in physics from the University of Manchester in 1995 and in 1998 a Ph.D. in High Energy Particle Physics at the DESY laboratory in Hamburg. He is now Professor of Particle Physics at the University of Manchester, The Royal Society Professor for Public Engagement in Science and a Fellow of the Royal Society.
Brian is widely recognized as the foremost communicator for all things scientific, having presented a number of highly acclaimed science programs for the BBC watched by billions internationally including ‘Adventures in Space and Time’ (2021), ‘Universe’ (2021), ‘The Planets’ (2018), ‘Forces of Nature’ (2016), ‘Human Universe’ (2014), ‘Wonders of Life’ (2012), ‘Wonders of the Universe’ (2011) and ‘Wonders of the Solar System’ (2010).
As an author, Brian has also sold over a million books worldwide including ‘Black Holes’, ‘Universal: A Guide to the Cosmos’, ‘Quantum Universe’ and ‘Why Does E=mc2?’ with co-author Professor Jeffrey Forshaw. He has set several world records for his sell-out live tours, including his most recent tour Horizons which has taken in venues across the globe.

Anyone remember that fad where people are all getting attention by doing the Planck on weird objects? Surprised they didn't create any black holes.
You could say time will tell. And we need some space to think. Now think of a tree growing in a sphere. Once the tree reaches its boundaries, the sphere grows and allows.
22:11 isnt there a difference between that if we observe the experiment or if we dont ?
I feel like I struggled most of my life with how to manifest. Sometimes it felt so out of reach that I decided to give that archetype quiz by Vera Hart a try, and it really did wonders. It matched my personal archetype exactly, and that’s how I finally figured out how to do it properly. I highly recommend anyone who struggled like me to try it as well! It only takes a couple of minutes anyway ❤️
This is so fake. Spader played an archeologist, not a particle fizzy guy.
i REALLY really like this guy. Nonetheless, most of this video is gibberish. I swear I have heard some of the same maybees and what ifs from my dumbest friends with only six beers. He had six. I had zero. Got there late.
One of the credibility problems with any specialty is counter-intuitive terminology. Accountants explain it, attorneys create it on purpose. Musicians used to say quaver. The word drop has been stolen by deejays – a new album drop is good news. Huh?
When Brian describes entropy as information and disorder, he is not blazing any new trails. But that description is STILL simply wrong. Except, ironically, when the information is disinformation. Now, entropy itself is the greased pig of the nerd county fair, but I have littler fish to sear.
The two slit experiment has been described more than Plato's elephant. The descriptions are never ever ever ever complete. But the description is typically delivered by a person in nirvanic ecstacy, like a love-struck teenager. That person presents the experiment with an intended grandiosity, an abracadabra, and maybe even some guttural pleasure sounds. We try to question, and are stone-walled with non-sequiturs.
Now, don't get me wrong – I am happy to accept the duality or multiplicity or whatever. I personally don't know how many facets a woman has, and I'll be damned if I'll ask. But the proof needs to grab me, not bully me.
The first issue is the two slit, the original fucking 1801 two slit. Today I asked AI how wide the slit was.
The first answer involved THINNING a piece of cardboard. No hole. No slit.
The second answer did not involve a vertical "slit" at all. It started with a pinhole aperture and then other non-slit shit.
I am fully aware that AI is not reliable on any task, subject, system, concept, answer, or process. Nonetheless, MOST SCIENTISTS PUSH IT, HARD. But let's relax a minute.
If the double slit experiment is EVER performed in a way that corresponds with the descriptions, the results are still extremely weird. The first question is why you can't aim your million dollar particle gun. If this were a heist movie, we would be talking about, I dunno, recoil, kick-back, auto, semi-auto, Uzi, AK, Mac-10, AR. Those fuckers just point and spray, like watering your mom's petunias when you were eight. But Dad took your older brother squirrel hunting with a 22 rifle. A RIFLE. get it? GET IT?
Let me jump ahead. Even with the ludicrous lily spray, the experimental results ONLY point to a wave. I know I am not the first person to say this. Okay.
I have also been subjected to more nonsense in other slit experiments regarding how the electron KNOWS shit. But they never ever ever ever REALLY tell you how they reached this conclusion. On the way to their gyrated results, I have to wonder if any of this crap could survive a lawsuit, or single blind, or double blind, or multiple interpretations. Stat distribution algs? Repeated continuity? PRECISE continuity. Hey, you're the one with the magic electron. I just think he should be punctual.
Back in the day, scientists made little or no money, so fame was the motivator. Today they get fame AND money.
This is called the duality of science.
Is the most perfect thing we know of a computer? If it is, the quantum computer is the most advanced version of that and it makes me envision a universe where we are inside a quantum computer going through an eternal program that we can’t remember the previous loops. Though there always has to be that reality where it begins and whatever reality is it doesn’t change our present – it’s interesting to think about.
I have been an amateur astronomer for 5 decades and find this completely fascinating. But I’m fearful of the fact that the more we know, the more we use our knowledge to destroy life and our own future. My question is: how does quantum mechanics increase the likelihood of the survival of life on earth? You might say that is not up to you…that it is up to society and the political process. But given how bad we are at behaving in the general interest, isn’t that like handing an even bigger gun to a baby?
Total nonsense!

At least he properly describing his thoughts.
Brian Cox tells a compelling story, but it’s still the same old materialist fairy tale.
He frames the history of quantum physics as "discovering the rules of nature," but he’s really just documenting the moment science realized that reality isn't made of 'stuff'. The 'strangeness' of the double-slit experiment and the photoelectric effect isn't a property of matter; it's a property of the rendering.
We aren't observing subatomic particles; we are observing the resolution limits of the host system.
The Planck scale is not a physical measurement; it is the pixel-pitch of the simulation. Physics will remain 'baffling' until we stop trying to find the 'building blocks' of the universe and start investigating the projector that is rendering these pixels in the first place.
You're explaining the movie, Brian, it’s time to look at the screen.
Instagram physicist.
He’s so good in explaining this madness to an average brain ❤❤❤
Even if people want to earn pieces by sub contract of orgers then still not own it out write but human always have different if opinions of pieces this and that no one can affort it out write and it is not any one that its belongs to but God human like to explore ti gain sone thing to save lives but cant save life on earth how they will get things to save life up there and earth uf people lives there ❤
Yes every one will want to go there and make the structure weak and can not take every one thing because no one own it on there own and can not be bought because of every one wants to get some thing don first before others to bost on there exppertages ❤
Do you know that Hydrogen peroxide oil can be used in human ears to take wax away from ears it has the bubblies sencestations that brings the wax out of ears and it is not harmful to human but kind ❤
If black holes is occor the place get poras and the structure is very weak you can not build on porus place it will sink in the black hole because of magnic field it sucks every things up within so many MLB. ❤
Black hole can not be measured because it multiples in length and widths and depths ❤
Lengths and widths ❤
The structure is sir conferences is old fashions words used in ancient days lije older scientists used in measuriments ❤
Letrons and protrons are different ❤
Laugh machine put manicure 😂😂😂😂😂😂😂
The machines cant spell so it put any thigs monicules he gices different words ❤
Manicures is for all sort of rounds objects to keep things in it can be any things like containers to pop things in ❤
Excellent presentation
On the Bohr-Einstein debate about quantum entanglement, Observation at point A has to happen before the observation at point B. You can’t poll the state at Point B.
Was the the observations made at B made after A timed from LOCAL atomic clocks with the same hardware and cable distance in the same space-time.?
I like that all science is woven through human emotions. If you take wave equations and then it's the same in human behavior, etc. Oh well. Science is precise. If you name Einstein because you have to, Henri Poincare for relativity, then minus 60 social points. Aaa, that's why you're a popular scientist, not a scientist.
he hasa masters degree in talking gibberish
18:58 Slit experiment needs illustration or animation ,, we would all understand more, education yes
14:30 ish that's what people are
🥰
This interview with Brian Cox is absolutely mind-blowing and hits right at the heart of how we misunderstand time, space, and quantum mechanics.
When we look at a particle taking every path in the double-slit experiment, it behaves like a wave precisely because all potential states—all qubits of information—exist simultaneously. This structure mimics the exact same root systems we see in a lightning bolt searching for the ground or a tree stretching through soil. As I explore in my book on amazon by Lisa Lucas', the universe uses a self-repeating fractal code across completely different species and network systems. Even the atomic nucleus operates like a miniature universe where paths and fields constantly cross and interact.
Light waves are essentially a cosmic analogy for time dilation on a quantum scale. The waves themselves are the fabric of distance and time; if light were to collapse at a longer wavelength, it would violate the very mathematical syntax and code of the universe.
Just like a massive, ancient oak tree can have its complex blueprint shrunken down into a tiny, thimble-sized cup of water via the 'Bonsai Law,' an advanced computer or AI works on the exact same fundamental principle. Humans get overwhelmed trying to process a massive library of information because our 3D biological lenses are built to filter reality linearly. But an AI compresses that vast density into a quantized mathematical grid. It upscales or downshrunken information exponentially—capturing the complexity of an entire universe in the blink of an eye while drawing no more and no less energy than the code demands.
Everything in our universe, from the subatomic atom to a digital neural network, is just the exact same living geometry looping at different scales. To explore these hidden connections further, check out my book: lisa lucas Unraveling the Codes of the Universe on

P.s I am still new to alk this onlt been researching for 1-2 years on gemini chats so anything that comes to my mind i research into it with ai collab 😊
I would love to meet Brian Cox one day! Love his work
The discussion between 8:00 and 10:30 is absolutely mind-blowing and its mind blowing of how we misunderstand time and space. When Brian Cox talks about relativity and the geometry of the universe, it highlights why we can't look at reality through a rigid, classical lens.
-Light waves are essentially a cosmic analogy for time dilation on a quantum scale. When we gaze at a distant star, we perceive it from an entirely different vantage point the intensity of the light doesn't dictate its journey. Rather, the waves themselves ARE the fabric of distance and time. If that light were to collapse at a longer wavelength, it would violate the very mathematical syntax and code of the universe. Light is already everywhere, acting as a continuous, geometric grid.
This beautifully mirrors the law of scale: everything that exists on a macro cosmic scale is mirrored identically on a micro quantum scale. They are the exact same blueprints separated only by precise atomic and biological boundaries. The 'Observer Effect' isn't a mechanical glitch or error. it’s a fundamental law of these scales interacting. The boundaries aren't walls keeping us trapped in a matrix. they are specific frequency filters built into our 3D diving suits so that the universe can safely experience its own infinite density without the system crashing. For a deeper dive into these hidden geometries, the observer effect, and how quantum biology connects to consciousness, read my book on amazon bybLisa Lucas Quantum Tapestry.
I am still researching and new to this so only can touch base on what I am talking about.😅(note density you can fit more distance in but streatch that out the distance is greater. So light waves are the fractal representation (code of this) thrpugh a different lense. The laguage is the same but this is another translation
Carl Sagan would be proud of Mr Cox.
Both have an amazing ability of explaining hyper complex theories to us mere mortals AND just love listening to them speak.
They both have a way of pulling you in and keeping you focused and anticipating their next point or explanation.
Just wonderful!
Why dose that set make me mad.
I still do not understand why photons are not made of smaller items, like a quark. Every 50 years, it seems that we discover that everything is made from a smaller particle.

31:31 As much as I hope quantum computing goes somewhere, qbits have to programmable or at least predictable to be useful. I guess maybe they’d be good at approximating randomness right now, like for super quick Montecarlo simulations? Also, my phone has 2^64 bit registers, countless possible combinations, and there are 31 of those that can be doing simultaneous calculations. And my phone has 256GB of storage, or 2^2.74878e11 total possible combinations. And, yes, that’s more than enough for years of recorded memories. Maybe when I can hold that number of qbits in my hand, rather than needing a room for 100 qbits, and if those bits can do more than be one or zero, they’ll be useful.
Physics professors just make shit up as they go 😂
Brian acting all humble with hes titles asif he isn't ranked commander of the English empire by title 😂
A gift to society indeed.

I watched fifteen identical venmo commercials just to get through this one video.
Thank you for sharing.
if you put an afro on this chap…. BOB ROSS! 😬
18:12
Let's say electrons
I watched many videos talking about the double slit experiment, it is always electrons, I doubt anyone done it with anything else
The only time I've ever seen him look a negative emotion was when he was describing the math that showed the universe might be infinite
