Steven Weinberg - How Do Particles Explain the Cosmos? 

Hello from Australia. 🇦🇺. I'm a rancher and waterwell driller from the south who is incredibly enthralled with this existence more every day, much thanks to learning more about these subjects.

If Steven Weinberg wasn't a physicist he would have made a great baseball announcer. Awesome, friendly voice. He looks like Grandpa from the Simpsons.

'We must deal with duality.' 'Yes & No.' 😂

RIP He truly was one of the greats.

An Interesting discussion trying to connect the largest stuff (the Cosmos) with the tiniest one (the particles). Well done CTT for bringing this great physicist and thinker who passed away some years ago, he usually tends to express the truth in his way. The point is that although we learned much, but we are still too far from understanding the "truth" of the particles and the "truth" of the Cosmos at large. We are still busy searching for the "Truth" and for the "Origin".

Always a pleasure to listen to the great mind of Steven Weinberg

Steven Weinberg, your first 2 minutes describe what happens when you walk with sheer intention for a long time in summer and spring. This is the mystic of life modern folks can't comprehend and fully understand.

part-I-cles (it's crazy but every word leads back to oneness) love these conversations though...

thank you for uploading this video! God bless you!! 🎉

Steven Weinberg, a theoretical physicist, used his mathematical prowess to impress upon us the theories considered today, that best describes how our physical universe works. This video is a reminder of the genius this man was.

What a Teacher !... Spirit !... Mind !... Brain !... A Greek friend, Demetrios Maniates.

I'M HAPPY THAT THE HIGGS IS BEING STUDIED, AND I'M HAPPY THAT L.I.G.O. WAS CONSTRUCTED. REST IN PEACE, PROFFESSOR STEPHEN WEINBURG.❤

If a scientific theory is tentative and uncertain it is not a scientific theory, it is a scientific hypothesis. Too frequently we call scientific hypotheses scientific theories and that degrades the meaning of scientific theories.

Truly amazing our accomplishments in cosmology and what we're able to do with quantum mechanical calculations. Steven Weinbergs book "The First Three Minutes,"which is now nearly 50 years old, is still very good in giving one an understanding of the early universe.

Thanks to Robert for inviting Steven Weinberg.

Thanks!

🧐 Interesting topic and discussion on this segment, 👏👍

"In the cosmic theatre, particles are the actors, their interactions pen the script, and the cosmos is their stage." - Inspired by Steven Weinberg

You always interview smart people, no question about that. But Steven Weinberg seems to be the most educated and smartest of them all. Just sayin.

Truly amazing. What is also amazing is to witness both the depth of scientific knowledge and that of human frailty and stupidity... Humans are strange 'things'. God must be strange too🤔

Back then WMAP and Planck satellites mapped the Cosmic Microwave Background

Newtonian mechanics including Newtonian gravity IS a "limit case" of General Relativity. BUT The Classical Physics "framework" is NOT a "limit case" of the Quantum Physics framework. General Relativity is a theory within the Classical physics framework. To "unify" it with theories in the Quantum Framework (standard model, QFT, QED, QCD etc.) we first need to "unify" the Classical Framework with the Quantum Framework. That is, we would ideally need to find a framework that has both: the quantum and the classical frameworks as different limit cases (each emerging as approximations under certain different limiting conditions).

I can’t help but feel that the cosmos as we know it are the particles of some greater reality we’ll never be able to comprehend the scale of….and perhaps this is a pattern that continues endlessly. Basically….the ending of men in black lol.

Wave functions and turtles all the way down….. and up. Decoherence underlies everything …and nothing.

Our whole universe was in a hot, dense state. Then nearly fourteen billion years ago expansion started, wait. The earth began to cool, the autotrophs began to drool, Neanderthals developed tools, we built a wall (we built the pyramids), math, science, history, unraveling the mysteries. That all started with the big bang. BANG!

There's three realms nested like Russian dolls, dark energy > invested into dark matter > invested into regular matter, and entropy/time happens at its own pace according to the wavelengths in the realm you're looking at and it's all E equals MC squared out of an investment of gravitational energy, and then recycled through black holes. Prove me wrong. 😂

Is my favorite physicist. But we all are physicists at heart. We not only live in and live with nature but are of nature. Learning agriculture, art, music, carpentry, knowledge, experience. We are all physicists. And what these "physicists" today have forgotten: how to live truly and once again wonder at yonder the stars, and exercise a bit of imagination and have fun. Listening this video here, it will take 1000 years before these men come to their senses and actually reckon what the giants of antiquity recollected. Quantum is irrational and made up to mislead academics. Those who never bought it in the first place are the real students.

Rocking the wave function is called Cyber Warfare

True, but an important question remains: - What was the cause of these initial irregularities ?!?

Such a clear explanation! Genius. Thank you.

A better title might be...Do Particles Explain the Cosmos?

Before thinking of PREDICTING future events or POSTDICTING past events we must clearly SEPARATE the meanings of: assumption, conjecture, postulate, hypothesis, theory, extrapolation, hope, expectation, projection, anticipation, guess, estimate and WHATELSE.

Dynamic depends on time. Physicists don't know what exacy makes time; rather similar to consciousness! They are talking about cosmos in the darkness.

Although just uploaded this interview is at least a decade old and I would say very out of date.

We got anser bro and it not quamptom fisiks. Edukate!

It's the disturb and wanted behaviour.

He was truly a great and profound thinker 🥲🙂👌

Thank you!

How do God explain cosmos ...!!!❤

Ele só ta dizendo, "a realidade nao é aristotelica boys".

Can't explane hole cosmic

Reality has no reality.there are no particles.nothing exist

And the fool said ‘Gravity is mind’……………………..🎉

...Please if I may, the reason that you only get the Probabilities of a Wave Function is because Time/Space moves as a Turbulent Flow, Gravity etc. in which Eddie's & Vortices will effect the out come, respectfully, Chuck...captivus brevis...you tube...Blessings...

To some extent, the guest resembles Robert Goddard, one of those inventors I loved reading about when I was a kid. Having said that, I get aghast when people who should be respectable scientists promulgate theories about the origin of the cosmos that lack any retraceable elements that could be experimentally tested to verify their claims. It is always a leap from the state of nothingness to the enigmatic quantum system and wave function. The core concept of science is incremental, not a leap system as shown in their expositions.

They dont

Are quarks gravitons? is dark matter centrifugal force?

Suggest checking out Plato's cave allegory

Understand Universe with particles It is inconsistency with Universe reality. unpredictable consciousness pictures universe but keep out How figure It out particles reality. Are particles marche with Universe real?Why consciousness show up particles It is random but figure It out is Impossible? It means figure out wave funcions though physic is nil evidence . Important question is why guys closer questions about Quantum mechanics when scientist doesnt how found particles.

Non locality.

Steven weinberg is real genius

Not a recent shoot. Steven died in 2021.

Well, no. At a fundamental level the universe is probabilistic and not deterministic- Heisenberg’s uncertainty principle has nothing to do with our in/ability to measure. It’s a fundamental property of the wave nature of reality.

I've never understood the idea that the earth is 13.7 BYO. Is that based on a 24 hour clock? Weren't days much shorter BB of years ago.

Steven Weinberg created the atom bomb, in 1945, when he was at least 25 years old. This video is 15 hours old, so he is more than 90 years old, but he looks 50. How does the media gain from pulling such pranks?

It's like listening to a pair of birds discuss what makes the wind blow. It's okay to admit that you don't know the answers to problems you were never meant to know about.

"How Do Particles Explain the Cosmos?" The answer to this question is IMPOSSIBLE because explaining the Cosmos requires understanding the Spiritual World of God that is beyond the physical realm... ...however, the following light might help you understand how and why the Cosmos came to be : We all are responsible for the existence of our Physical Universe because we were once ONE WHOLE GOD who created this Great Cosmos before He split Himself into free souls (us). In other words, as One Whole God, we all have the hand in the decision to split and the decision to create this Universe. So, God alone is not all accountable for all the consequences of the decision to split just to have a free loving family. WE ALL ARE RESPONSIBLE ! You soon will discover this truth when your temporary "life's chance of salvation through faith" ends where only your immortal souls survive... In the beginning is the "WORD" which does not mean man's vocal chords but means the vibrations of spirits from a tiny portion of God's infinite Spiritual World that had FUSED to create our Physical World. This is how the Universe begun, not by explosion nor inflation but by FUSION... ...and, as ONE WHOLE GOD before we split, our purpose for the creation of this Cosmos is to provide a temporary home for free splits, or us free souls, who may go astray for a chance of salvation through faith. You are always free to choose to ignore this light and continue staring at UNCONSCIOUS Bigbang as the origin of your AWARENESS.... Looking like a funny clown is also a choice, so, go ahead..

*The World of Physics:* "The universe is expanding, but that doesn't mean it has any size. We can trace back the universe to 1/10 of its size, but again, it really has no size. We currently lack understanding of elementary particles. There are "exotic" particles that we desperately need to know more about. General Relativity and Quantum Mechanics don't work well together. When QM is applied to space and time, we get mathematical inconsistencies. You can only make probabilistic statements about the behavior of particles. We don't have a decent quantum theory of gravity. There are conceptual problems with the wave function." I do not believe in God, but based on the above, I can see why they still believe. After all, ... why switch trains when the other one doesn't even know where it's going?

The predictable orthodox explanation. Funny about the “dress code”.

Let's further explore how redefining fundamentality around 0D instead of higher dimensions could revolutionize physics and beyond: Quantum Gravity and Unification: A primary motivation has been resolving the incompatibilities between quantum theory and general relativity. Theories that derive 4D spacetime from more fundamental 0D network nodes could accomplish this: - Loop Quantum Gravity's spin networks providing a discrete 0D substrate from which geometry and gravity holographically emerge. - String/M-theory with vibrating 0D strings as the ultimate realities, dimensions arising as compactifications. - Causal Set approaches modeling spacetime as a discrete order of 0D event nodes and causal links. Unifying all forces as geometric degrees of freedom in the 0D network could finally achieve Einstein's dream of geometrizing physics. Quantum Foundations and Information: Moving to a 0D primacy framework could resolve many interpretational paradoxes in quantum theory: - The measurement problem by modeling observations as information transfer across the 0D network - Fundamental non-locality by having no underpinning space to be local in initially - The role of the observer by treating perception as information patterns in the 0D physics It could reveal quantum theory as an effective statistical mechanics of information dynamics on the 0D "atoms of reality." Cosmology and the Universe: Deriving our extended dimensions as emergent could shed new light on cosmic origins and structure: - The Big Bang as a holographic projection outwards from an initially compactified 0D seed - Cosmic inflation as rapid 0D network growth generating space quasi-classically - Dark matter/energy as geometrical degrees of the fundamental 0D network condensing our observed dimensions - The cosmological constant problem and naturalness issues resolved by dimensional emergence Universe lifecycle cosmology could arise naturally from the network's discrete evolution. Mathematics and Modeling: Even mathematics may need to be rebuilt from the ground up in a 0D primacy paradigm: - Algebraic topology, category theory, and homotopy mapping the 0D network dynamics - Geometric algebra and non-commutative geometry as the 0D variable structure - Discrete computational frameworks like cellular automata and artificial networks replacing continuum models - Novel logics, computability and complexity theories based on the fundamental 0D algebra From pure mathematics to physical applications, we may need to upgrade our entire conceptual toolbox and language. While unimaginably difficult to develop rigorously, the potential advantages of such a primordial 0D framework in terms of conceptual unification, infinity avoidance, quantum reality, and derivation of all observed phenomena make it an enticing goal for pioneering theorists across disciplines. Every branch of physics and connected fields could be rewritten from the ground up. The sheer ambition and profound impacts on our cosmic comprehension mean every path must be intrepidly explored.
