🔷 The Conglomerate of Universes - Universe Creation Theory 🔷 combining GOD/Nature, ancient religions, astronomy, cosmology, fined-tuned laws of physics/general relativity/quantum mechanics, chaos theory/fractals, laws of biology & chemistry, linguistics/code-breaking, programming the Universe/GOD=7_4 or FOD=6_4 theory, intelligent design, mysticism, and philosophy/anthropic principle "Energy can’t be created or destroyed, only transformed/transferred in an isolated system." General relativity's black holes, white holes, Big Bang and wormholes. ‘The BIG Bang-Bit Bang’ inflation/expansion of energy₇₄ and information into the void 13.8 billion years ago was a supermassive white hole spawned by a supermassive black hole at the heart of a galaxy in our ‘parent₇₄ universe’. This duality combines general relativity’s singularities of infinite density breaking through spacetime in ‘Cosmic Egg hatchings’ of all created universes within ‘The Conglomerate’: multiverse with no random quantum fluctuation bubble universes, no parallel worlds, and no universes with different physical laws. Our Universe is 1-in-2 trillion ‘self-similar offspring’ each with the same inherited ‘DNA’. “In the beginning”, the Planck density of the core of a SBH is a birth canal. ‘Quantum bounce SBH-SWH seed transitions’ are ‘quantum tunneling umbilical wormholes’ with energy-matter and data transformed/transferred, albeit scrambled and encoded. The ubiquitous cause-and-effect ‘circle of life cycle’: birth-life-death-transformation-rebirth explains infinite space and eternity - a necessity. Reproduction is GOD/Nature’s plan for greatly spreading life from cells to universes. GOD=7_4 or FOD=6_4 is the #1 program₇₄/law/initial₇₄ condition (Seal #2). Why does this Universe exist? It’s our playground (god + run = ground₆₄). - Seal #1a of the 7seals.blogspot.com . Only the returned Christ & Albert Einstein reincarnated could produce this - it's triggered The Apocalypse/ Revelation which is NOT the 'end of the world'.

Even if there were no charged particles, there can be electric fields. If there were no moving charges there still can be magnetic fields, similarly if you remove the planets you will still have gravitational field, IS NOT TRUE, not observable and not verifiable. Sorry Sean Carroll, you are not paid enough to answer such questions, as you admitted, but you were paid enough not to misinform the public. Schwartzchild assumed g=0 while proving/solving the equations of GR.

Sean Carroll is a national treasure. He is a great teacher and a great mind all in one. What he says about patience and physicists is true, but he seems to have found a pragmatic loophole through which he can communicate effectively. In earnestness there are clues that exist through human pathos, though not all that is science, it often provides more information than the fundamentality of boilerplate. Thanks for this.

Thank you, Hagen, for bringing me to this lecture series .... much appreciated.

One of the most enjoyable lectures I watched... very clear and entertaining at same time..

I think this is Sean's best talk. I've never heard Quantum Field Theory explained so well. It's these sort of higher-level talks for the everyday physicists that I believe will lead to unified theory of all dimensions & forces.

Worthwhile talk by Sean Carroll on the basic of QFT at a level suitable for high school students.

Best science communicator I've found to this day. I feel much, much, much more deeply educated after listening to him explain a topic than others I've ever heard. He has a very unique talent for simplifying topics to the level of the layman without "dumbing down" the science - or more specifically, he can simplify a topic without doing so in a way that sacrifices scientific accuracy and rigor in order to make it fit the audience's prejudices and past mis-education. Or, maybe I should say he clears up misconceptions as he speaks while others I listen to try to just pass over the misconceptions so they can put it on our "level." Sean instead raises consciousness and understanding so we can be properly educated.

He is communicating the basic concepts in terms that a journalist or doctor, a non-physicist, can understand and at least appreciate what the underlying concepts are. He likely doesn't know much about the gall bladder, but somewhere he took a biology course so he is scientifically literate about the fact that it produces bile, or whatever. What's that mean? He doesn't care, that's a doctor's job.

That's a tough subject. But some youtube vids give a bit of an idea. If a deeper understanding is what you're after you will need calculus (differential equations) and a very good understanding of "tensors" and vectors. It's a process. There is no easy shortcut for GR. (I shouldn't even attempt it, but: gravity is a distortion or curve in otherwise flat space. This curve is generated by matter (or mass). Once space has a curve, the stuff in space follows that curved shape. It feels like acceleration. That acceleration-like thing is gravity. If you were driving your car in a straight line you would feel nothing. But turn the wheel and make a curve: you feel a force. Now lets say that curve is actually a straight line, and it is space itself that's curved. You would feel a force no matter what path you tried to take. This is sort of what gravity is. And matter puts the curve in space. Everything is trying to follow a straight line, but all straight lines drawn on a curved surface are curves themselves. So that's your 'gravity'. The more matter, the tighter the curve gets. The tighter the curve, the more gravity force you feel. Even if you are not moving, but you are in curved space. ....Well that's idea in a paragraph anyhow. It really needs some time and effort to appreciate. So check out some vids and go for it.

David Tongs explanation was also excellent. I've watched that one a half dozen times and learn something new each time. I have high hopes for this one too

1:13:00 the early universe had low entropy because black holes have low entropy. A black hole is a pocket universe. Gravity, the curvature of space time, is concentric (it is the pulling of space time) when looked from outside of the black hole. Like that ">" But from the point of view of the singularity, space is expanding. Outside gravity appears as expansion, as dark energy. Let me know if you can see what i mean. Thank you

Sean,Imagine a Probability Density FOURIER pulse to be stroboscopic, whose time between collapses is constant and the pulse existential time a function of energy. All fields coexist in the totality of space, and could vibrate, given a characteristic range of each field, in the presence of a given quantum levels of energy, that generates the pulse that characterizes the particles we detect during collision. The Probability Fourier Pulse concept is the same mathematically as that for generating standing pulses for string instruments. The displacement of the pulse is not continuous given that, a collapse is required before it resurges at a given infinitesimal distance. Please notice that this model is consistent with” time dilation” at significant levels of velocity or when it is stationary at a significant gravitational pull

How do we really know there are distinct fields as opposed to just one field whereby the multiple fields perspective interactions (or lack thereof) are some sort of additive/subtractive synthesis of the singular underlying field of reality?

If we could reduce the energy in the Higgs field, couldn't we technically reduce the strength of mass? Regarding the graph, it was mentioned that we could increase the energy to reduce mass, but that would require adding energy. Why not try to reduce the energy?

No mention of particles entanglement, or did I miss something ?Implications for nonlocality in time and space are interesting, I'd like to hear some explanation of this...

Just a question in the off chance any real physicists enjoy reading these comments. Suppose a photon is traveling at velocity C in the vacuum of space. From Special Relativity we know that time has stopped and distance means nothing in the photons inertial frame of reference. But in our frame of reference the photon is seen traveling at C and consists of an oscillating electric and magnetic field. From the frame of reference of the photon, when does the electric and magnetic fields have time to oscillate?

Bill Schlafly, that is why it is best not to make such claims. If having a belief about reality causes distress when it is challenged, then it is probably not a good belief. My understanding of science is that there are models to use to make predictions and explanations. If a better model comes along, use that one instead.

Machine learning could be applied to the particle collision data to try and better detect anomalies than just humans.

The universe is made of only one sub-atomic particle. This particle has 3 states - left spin, right spin and no spin. Empty space contains only left and right spinning particles which are unattached. These particles spin at the speed of light. Matter forms when a spinning particle stops spinning and creates a hole in space which the spinning particles rotate around. The sun gets its energy from these spinning particles which are pushed together as they approach the sun. The spinning particles give off their spin energy - 2 particles pushed together - E=MC squared. Light travels through these alternately left and right spinning particles like the cogs in a watch as a spin/wave. Thus, spin energy is the common denominator which unifies all the elements and forces of the universe.
