Not an "um" or an "ah". But a continuous unbroken flow of rational, logical information. What a pleasure to listen to. A lecturer of the highest order. Bravo!
Stop it, he's not logical. 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
He is very personable and articulate. I enjoy listening to him. Of course he is an atheist as are most physicists. They believe in one dimension only; the elemental. They do not know of or acknowledge three dimensions: Consciousness; Mind; Elements. Consciousness being fundamental; Mind; elemental and the physical dimension also elemental; grosser or denser elements; all emerging with quantum events. That is why there is the hard problem of consciousness for atheistic philosophy and science as they see one dimension only.
Sean says that he never gets tired of being amazed at the human imagination and at Nature's stubborn insistence on following its rules of physics. But I will never get tired of listening to Sean describe how this universe works. His enthusiasm, his clarity, and his stubborn insistence on giving a fair hearing to all sides of controversies in physics is joyful to behold. Sean refuses to remain stuck in the mud of mysteries, but instead lays out the directions we can go and patiently awaits the march of science to determine the best direction. He reminds me of the "color commentator" at NFL football games. He doesn't just give "nuts and bolts" statistics of how many yards were gained. He tells stories of the players on and off the field and how that relates to their performance in the game. We humans may understand math, but we also understand through a good story. Sean is the master color commentator, telling stories that help us appreciate the "action on the field".
I’m 28 years old. I’m not a student of any kind. I attended a few semesters of community college. My job has NOTHING to do with quantum mechanics, academia, or particularly difficult concepts. I’m just someone that loves to learn. Knowledge is a gift. The more you learn about existence the more beautiful it reveals itself to be. Every academic field, every culture, even different beliefs systems, allow more of the universe’s richness to come through. Instead of chasing one truth, learn to see the many truths that people use to interpret the world. You have one too. Thank you Sean Carroll for spreading knowledge in a concise and entertaining way. You’re a cool human.
Thank god for the internet so that people like you and me -- another person with no knowledge of physics but who loves to learn - can access such amazing content as this, so easily!
I could listen to Dr. Carroll for hours. Like Brian Greene, Lawrence Krauss, and a few others I watch on a regular basis, his ability to elucidate complex phenomena is amazing.
@Joe Chang I don’t know what you’re smoking but you might want to sit down. I love when people question the validity of science while using technologies that depend on the science they are questioning. Might want to keep your day job dude! 😳

I absolutely love Prof. Sean Carroll's lectures!! He makes it so interesting even for laymen like myself!! He has such vast knowledge and never gets boring!! Love it
He reminds me a little bit of my physics teacher for the year I had to take in college for my biology degree. I never thought I'd find physics that interesting but I did.

As an engineer who has always been passionate about math and physics, I was intrigued by modern physics, despite neither relativity nor quantum mechanics were part of any course syllabus at my university. I studied these subjects on the side and found them really inspiring, I would go as far as to say that they gave me a novel perspective on life itself. That prompted me to create some online courses on Udemy on Quantum Mechanics, Quantum Field Theory, special and General Relativity. It’s not my job of course, but I love talking about these topics while using some mathematics for “intuition”.
Quantum Entangled Twisted Tubules: When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else.
I especially liked his interpretation of connecting Einstein's space curvature with quantum geometry versus energy and entanglement. That is the best interpretation I have witnessed of connecting Einstein's 'Classical Interpretation" of gravity with Quantum Field Theory. I have been looking for someone to describe a possibility and this one seems plausible.
But will it be enough to make a theory of everything? In other talks he shows that gravity in the core theory equation is quantum and it is good enough to be accurate one large scale, just like relativity, but not in extreme cases like black holes etc.
Sean is really a great educator. He is able to illustrate very complex subject matter in a very intuitive and passionate manner. I was really never good a physics in high school esp. when it came to the math and the corresponding formulas. Yet, I feel I have gained some basic understanding of the theories presented here and in other lectures by Carroll and folks like Brian Cox, Richard Feynman and others. I am very much into the arts and I find that the arts and the sciences can inform and inspire each other. Connecting it to the real world. It reminds me of the great and beautiful gothic cathedrals that inspire but were only made possible by understanding physics.
He's not even following science. 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
@@VeganSemihCyprus33 your video is bullshit. I didn't need to see any more than you making the statement that five coins are somehow "related" in their odds. This is the kind of ignorance of statistics that causes problems with the public. Pure bullshit.
Thank you for such a great presentation. Dr. Carroll can speak for 24 hours non-stop and I won't fall asleep! Particularly liked his version of explaining the QM anomalies - not by "quantizing" our conventional classical models, but ground up from a native quantum mechanical universe.
The quiz at the end of the lecture joke never gets old. Sean is a great orator. I am just geting into the world of Physics and am really enjoying his talks.
Wow, great lecture! I've devoted nearly half my life to studying physics, but I never really thought of it in this way. Sean both explains, at least in part, many of the biggest mysteries of physics and points to new ones. Great job!
Gravity should be updated as such: 13.3321 m/s^2 and the general theory of relativity should be this as a LAW : ((G*2073)R)) --- --- --- That is why we struggle with physics because we believe in Einstein's postulations of physics as such: ( E=m*v*3000) is the Law of Special Relativity.
The content is as old as Sean himself. Easy money for him. But Darwin College is feeling great ... only because of his name/fame. Fine presentation though.
@@ericgraham8150 I agree. But it's the same old story over and over again. It seems there is nothing new in physics to tell about. Going deeper means going more mathematical (and further from reality). There's no audience for that ... even at Darwin College! ;-) And that means there's no presentation and money for Sean.
you'd be better off studying some science for yourself then listening to some actual lectures, not this bafoon dumbing everything down... you'll never gain any knowledge by listening to lectures like this one
@@demonlord360 regurgitate me better crap drawn from more domains and I'll happily listen and compare it to what Sean Carrol has to offer, but I havent heard a podcast of his in which i didn't learn something
I have read that Newton also was troubled by his theory's "action at a distance". He kept his discomfort to himself, because he, like others of his day, did not believe in action at a distance in physics. In this regard, he did not differ from Einstein whose Relativity did away with action at a distance. I find that Newton was, in this regard, much further ahead of his time than all other physicists until Einstein, to whom he might have said, "You know, I had been thinking along the same lines! I got as far as calculus, but I had not applied it to the geometry of Riemannian 4-dimensional spaces as you did, because Riemann had not yet been born in my day; but I knew something was wrong"
He sets up Schroedinger’s cat experiment beautifully and builds up the explanation to......multiple worlds hypothesis, when you think about it it’s not any more satisfying, now we have neatly infinite copies of the entire universe to accommodate all the possible quantum events. That’s a lot of stuff, I’m not sure this is correct, I’d like to trust him but I’m not sure he advanced the argument very much.
It is an amazing speech worth watching no matter if you love physics or you are not really interested in it. In my opinion everyone would enjoy this lecture and start to think about some incredibly mysterious things around us.
This man has given me so much insight into how this world is and came to be (after the big bang) and why it is the way it is - and I have never taken a physics class nor have I taken a higher education math class - he is such a joy to listen to and my moments of understanding astound me!
He's incredible. Spoke engagingly for an hour with barely a glance at notes. The lady introducing him, however, could scarcely utter a syllable unless her head was lowered and fixed onto her notes.
I think the answer to the quantum mystery is just the idea of quantification itself The universe does not have exact numbers to correspond to it what is rather always in a state of flux An example would be saying that I'm 6 ft tall. It's just an approximation. Someone's exact height is always changing but we give an approximate estimate This is the same with all quantification. It's only accurate within the margin of error Height weight, any mathematical description of a system is just an approximation In reality the electron is distributed in a cloud and always will be But when we give mathematical descriptions of a system we're basically giving an approximation that has some utility Therefore all the terms like superposition wave function duality, they're all just terms to give some Precision to something that'll always be Beyond quantification It's like the shape of the Earth you can say it's a sphere or an oblong spheroid and that is more accurate than saying it's flat But the utility is always based on a relative system. in reality the shape of the earth is always changing slightly Anyway can someone hit me back and see how we can get these ideas being discussed by physicists like Sean Carroll I think what I'm saying here is a more basic idea then the many-worlds In reality many worlds is just a an attempt to give Precision to the universe the same way we give Precision to the shape of the Earth. But in reality such linguistic terms will never capture the Nuance nature of reality. I think it's more fundamental to just say that quantification will always be accurate within the margin of error and that the actuality of reality can never be precisely described in any way that is true for all Observers. So again the fundamental mystery or Indescribable nature is due to an attempt to quantify what is beyond quantification in an ultimate sense!
Don't know what you thank him for. His lies? 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
I am a complete dunce when it comes to physics but this man brilliantly elucidates and makes genuinely exciting every aspect of the subject in a way that even I can not only understand but also enjoy. Never an umm or an ahh in his monologue his voice holds the attention in the most astonishing way. Ten out of ten! Just riveting!
It's now much more clear to me how consiousness is the biggest key factor on every topic that he covered here. His composition and presentation put it right in front of your face on each point, making consiousness the most obvious missing element to every problem, without coloring it in for you like so many other do. Terrific presentation!
Thanks! I was looking for comments about who the guy resembles. It is a bit of Q but I also see Adam Baldwin in there. Its like that guy from Classic Game Room has put on Adam Baldwins skin. Still not quite it. There is someone else but it wont come to mind
@@joeboxter3635 people said that about Einstein's black holes. About quantum mechanics, the god particle and anti matter. Basically it's not what he says it's where the math leads to. And every scientists will tell you that at any point anything could be proven different than we thought. Fact is
Strange how even Sean Carroll gets this wrong; In the bullet cluster the red is indeed where the mass is. However, the blue is not where the mass is but instead where the gravitation is. If the blue was also where the mass is the blue would have behaved just as the red did. Ha yes, gravitation in the absence of mass is the new conundrum of modern physics. {LIVE Science; Forums, History and Culture; Culture History & Science; What is a living individual and is it naturally universally mobile?}

THAT was a fantastic lecture. I only WISH when i did my degree they talked about entropy as information - when i realised that, it kinda clicked! And that when he jokes about "i swiped my arm because the glass was going to fall", thinking about entanglement first, intuitively is backwards, since our whole life experience is centred around us, it was insightful. Great lecture!
this is an Incredible Documentary and i could listen to Sean Carroll for hours, he explains physics in such a way that even if you don't know anything about it '' you will understand what he is saying, *
Sean is a great exemple of an open minded scientist, it is very nice to see. Krauss or Neil Degrasse Tyson on the other hand, are the perfect examples of a close minded scientists, almost religious in a sense. If he's asked a question he doesn't know the answer, he will tell you : Look, I can measure the phenomena, if that is not enough for you, you can stay here playing with your '' Whys '', while me and my colleagues continue to go forward. He will then look at you with the most ... arrogant face in the world. Which to me is unnaceptable, in the scientific world. So I totally believe Sean when he says that the scientist that was asking questions was ''gently'' tossed away. Sry for my bad english.
I totally agree with you. A lot of famous science personalities will quickly say, “that’s not my field, go somewhere else for that.” Yet, science in general has colonized other domains of knowledge. Science is the new cosmology and philosophy. The scope of science is accurate but limited, you can’t encapsulate the world with just science; nonetheless, they keep trying.
It's good seeing Sean finally coming into his own skin and accepting the fact that he is responsible for enticing the next generation. Thanks Sean! 💪😎🇺🇲
Does anyone feel that our cross-over from classical to statistical mechanics may have brought us astray? Statistics summarize observations. Statistics shows your the louds, and how clouds move; it don't tell you how the clouds were formed. Statistics can give you intuition, and narrow down theories. But I feel like we are stretching stats to a dimension of abstraction that we've come so far, that we've convinced ourselves that the equations that can explain statistics, are somehow reverberations of the underlying classical truths. Although I find this an insightful path, we must not give up on the pursuit of there being a classical description that we have not yet accounted for the variables for.
31:00 Finally we see the casual photo of Everett! Sean wanted to put this in his last book but couldn't secure the rights. He had to use the same straight-laced photo that appears everywhere.
Maldacena conjectured that the whole universe is QC function evolving from a single wave function. Phase transition of non-life matter to life and consciousness is also a QC function. We just don't know the self-error correcting algorithm of QC function that eliminates randomness/chance (fine tuning of the parameter space) to achieve probability one state.
There are some folk who can make science very exciting without using any wizz bang in the presentation and it is much appreciated. You get the same quiet satisfaction from putting the right ingredients together and baking them into a loaf.
Addendum : Some more CRAZY question / points : 1) Electron is spinning! 2) Proton is vibrating! 3 ) Both make neutron/s chargeless! 4 )Electron keeps everything entangled as well as in order or in disorder (entropy)! 5) That means electron photon interaction... may help us to understand the theoretical points : a) The -e- is there, when we look at it...and not there, when not looking at it... right...!!!??? Therefore the above points may also suggest the ELECTRON being part of the classical science and photon being part of the quantum science...could lead us to the territory of GUT...!!! That means all the theories of all those famous Scientists are the contributors for the present TOE and GUT... in micro and macro levels... A BIT- BY - BIT...!!! THANKS AGAIN DR. SEAN CARROLL...!!!
When even the Chair of Physics at Cal Tech struggles to explain entropy (hint: an egg is never a good example), we need more clarity on the concept of entropy.
Entropy is defined as dS=deltaQ_rev/T. What in the world is hard to understand about this? A simple interpretation of entropy is the amount of heat energy in a system that can not do useful work (on an external system).
@Bertrand de Born WOW! Somebody deeply hurted you to make you so angry....but you and some others are the MEN who found out the TRUTH about modern physics....LOL.
I am a layman. I have a relatively limited education, but it seems to me that gravity is such a surprisingly weak force because it is diluted if you will and spread across all the "many worlds" or possible states. The other forces are not and are local to each possible state. Sorry, I'll show myself out . .
That is actually one of the concepts out there, but the standard idea is that it leaks from our "brane", meaning our 3D/4D slice of a higher dimensional object, into those higher dimensions. It's more related to a multiverse idea stemming from String theory, rather than the one stemming from quantum dynamics (but these might turn out to be one and the same, or both active, or both false). What I wonder about is whether the notion of a quantum multiverse fits in that String theory perspective. On the one hand yes, since one could argue that the quantum bifurcation of universes happens in another dimension. On the other hand no, because bifurcation is fractal, instead of plane-filling in nature. If you're right, one could imagine then that if the universe wouldn't split, gravity would be stronger, because it didn't leak. We could perhaps test that in a bubble of Bose-Einstein condensate. Perhaps we would see that gravity is altered inside the bubble, being stronger than otherwise expected.
@Ahura There seems to be no explanation as to why gravity is such a weak force. My guess, if correct, could explain that. String theorists have a similar opinion based on far more knowledge than I bring to the table.
@Ahura Look it up but there are only theories and guesses. I can't see how any of this is testable or how any experiment could be devised to prove it. It seems strange that only gravity would be constant across all dimensions/worlds/branes but if true it would explain why gravity is so weak.
@Ahura I just found this. It's a very short video but might wet your appetite to look outside classical physics. I am really out of my depth here and only class myself as "fascinated." th-cam.com/video/s7Babitv4Fg/w-d-xo.html It's a 4 minute clip from 2008 and only speaks of one other parallel universe. Sean Carroll (who's ideas fascinate me the most) takes this much further and theorizes about infinite universes.
But all the forces would be spread out to the other worlds too? By that logic, I don’t think it’s useful to think about the other worlds of the multiple worlds hypothesis as having any effect on our universe, they are disconnected from us are they not?
I totally agree with Joe Gelman below. Sean Carrol is brilliant and inspiring teacher exactly in the tradition of the Great Richard Feynman in whose chair Prof Carroll actually sits both metaphorically and literally as he often points out at the beginnings of his talks. I have some his books in audible format simply because I like the sound of his voice. His proof that Death really is the end (see the youTube video) inspires one to live this one to the full as its the only one you'll get. Of course, if we are simply running as simulations in our own future descendents' super-computers then let's hope no-one switches the power off which would amount to the same thing.
This may be profound. It is easier to move through time than space. So "nearby" is preferred. The fastest you can go through space is 45 degrees on reference diagram(speed of light). But 90 degrees of range is available in the Time direction (2x45). SC knows Relativity, so i wonder what implications he may be making?

Memory formation is an entropic process. Ink to paper. Bit on CMOS. Synapse strength growing. All have an energy cost and energy waste. This is why we remember the past, because to commit a thought to memory is to consume and dissipate energy. To store a bit into SRAM is to take a burst of energy and turn it into heat, raising the temperature of silicon. No need to use "past hypothesis" to explain the arrow of time in terms of human experience.

thanks, Sean, for the splendid lecture on the basic problems of modern physics. surely, understanding of life is fundamentally inportant and can give us a key for the better understanding of quantum mechanics and of our physical reality as a whole (as well as of ourselves in this reality, i guess))
I love listening to his lectures. Such a brilliant man. Judging by his choise of suit and tie he clearly aims at maintaining a low entropy state in style for much longer than Einstein.
One could argue though, by viewing tieknots as a self avoiding random walk on a triangular lattice (see www.tcm.phy.cam.ac.uk/~tmf20/TIES/PAPERS/paper_nature.pdf), that a state of even lower entropy could have been achieved by tying the tie into a "Oriental" style tieknot (a tie knot wich requires only four moves: left, right, center, tie), instead of what looks to be a (very stylish) "Half-Windsor" (requiring seven moves: left, right, center, left, right, center, tie). On the other hand, a Half-Windsor looks tidier, so that may make the Sean Carroll system as a whole at least appear less entropic :P
My biggest question is: if we are governed by the law of entropy, how come evolution took place? Evolution is not random, the fact that at one point in time atoms bonded into molecules, then protein chains then cells and organisms now so amazingly complex, doesn't look like entropy to me... so I don't believe in entropy. There must be a reason behind why particles decided to become humans who study particles, and not just dance along in space ever more chaotically.
I once quoted Mitch Hedberg while TAing an intro to electronics course because students in the lab couldn’t tell me what a “resistor” does. “I wanna have a job in the ‘kitchen appliance naming’ industry. That seems like a cool job to me. Toaster, blender, refridgerator.… just say what the thing does, and then add ‘-er’! What’s this thing do? It keeps shit fresh. Well, that’s a fresher. I’m going on break.” Crickets. My delivery was so bad.
Science Kermit is best Kermit. Seriously though, I'm become a big fan of Professor Carroll as a science communicator. Hope to hear much more from him in the future!
GRAVITY EXPLAINED, universe is made of minute cells once contained in a universal shell that was broken or deformed by an external force. this produced expansion creating a true void that must not exist, leaving the cells to expand or split,I believe the destruction or splitting of cells is where all matter originates, therefore all the contents of this universe will become matter and the universal matter will disperse or be contained by an outer external force or medium. The cells must penetrate already created matter to a degree, becoming harder the denser it is, until it is so dense it is impossible. thus the push back is multiplied infinitely causing corresponding gravity push... As far as so-called gravity it is plain to see that there is no attraction, only an external push forcing matter together . Imagine an oil filled rubber ball each molecule of oil must have the same force upon it. Then introduce a foreign particle of the same size and density then each molecule will have slightly higher pressure upon it nothing will coalesce then add a larger or denser body with larger or harder surface to be pushed upon by the other molecules all the molecules will feel a small amount more push but the nearer the large body cells will get pushed harder. [this energy really comes from the constant push from the ball membrane or what exists outside it] then introduce a smaller dense body in the vicinity of the harder pushed cells. if the number of hard pushed cells behind this body is higher than the ones between it and the large body then gravity is achieved,,,unless the pull from the expanding universe shell is greater.. Without resistance to these cells energy would not be forced to navigate a wave pattern, the cells would not become excited and light as we know it would not exist . Energy waves passing through harder pushed cell formations will deviate around the reason they are pushed. Hard pushed cells may be deformed from a sphere into an ovoid making it harder to rotate, also making energy travel differently The universe itself may be such an ovoid thus the reason for expansion. Magnets must electronically rearrange the cells shape and alignment making the rearranging object harder or easier to navigate between depending the manufactured configuration. As far as Quantum physics goes we do not have any real data so mathematical physics is applied and comes up with sometimes fanciful answers to fit a paradox. Understanding a data lacking subject has always failed people already in this field would do best just striving for accurate observation as some early astronomers did. An understanding will develop with detection instruments and supercomputing enhancements , seeing it first hand. some bright spark will discover the bleeding obvious and mathematise it. We must determine the size and density of each cell by measuring each light wave in relation to one another ,and the number of cells between each crest and finding the correlation that would fit all known energy waves if this can be achieved, the next step must be to create corresponding energy waves before a moving object creating an air in sand effect thus help said object closer to the preceding wave speed Initial measurements should be simple two dimensional with known wave patterns overlaid on the same plane and begin with spherical solid cells filling the voids between the crests of all waves. First, hoping all the energy waves respect the integrity of each cell, if not some types of energy waves may penetrate part of the cell, as do they penetrate some matter. black holes are remnant void bubbles still trying to eliminate the space where cells are absent,destroying surrounding cells and creating matter and drawing existing matter to fill the void .billions may have succeeded leaving small super dense spheres but most can't keep up with the constant universe expansion and will take all their surrounding galaxy and more. No matter how beautiful and pleasant maths is , since the mid 60's, it has blinded physicists before then a physical notion was envisaged then came out the ruler to see if it would stack up. These are some answers to how things unfolded but surely the harder question is why. Why has life evolved to a stage that we can pose these questions? Surely non existence would be the easier option ,without struggle without knowing about your inevitable destruction personally and universally this question is the real puzzle. This is why the emergence of conscience coincided with a genetic predisposition towards a god culture everywhere on earth ,a genetic valium so to speak. which must be ameliorated not railed against by atheist dissenters , its just DNA evolved a part of our bodies to believe so as to survive longer. The answer can only be chemistry ,all life is simply a chemical reaction , the same as the stars react with each other ,no matter how complicated its components become it must rely on the basic building blocks to exist ,my thoughts while writing this are governed by a chemical reaction and the lightning created by the reaction. Therefore if matter has no will and the meeting of different types of matter will react differently then the meaning of life has the same weight as mixing paint ,life and death is eventually inevitable wherever matter coalesces .,..
Math, like numbers, is a language humans invented to describe relationships more usefully than words. It chokes me when people talk about math like it's something discovered that was used by god(s) to create our universe (if it is a universe).
Serious question: when we talk about quantum mechanics, I imagine... stuff... that is so small it is impossible to see with thr naked eye, so people use machines to "observe" particular (re)actions. So what does he mean by "we don't know why when we LOOK at it, it doesn't act like a wave" ? Clearly the act of observing, done through a machine or whatever experiment they're doing, acts upon the quantum element and changes the way it acts when "observed". So I want to know how do they "observe" the elements without affecting them?

DogGambit ha ha perhaps you're right. Maybe out there somewhere there is one universe where the field of science is NOT filled in and about with excessive numbers of pompous asses, clearly not mine as you so amply demonstrated. Eh! eh! _Got my _*_thought_*_ that time!!! eh!.._ ..:-)
@@4pharaoh - Of course I'm right, because when I said "It is always fun ...", I meant it is always fun for me, because I'm a fun loving guy. I can't claim to know about others. Claiming to know that would be pompous. Also, my observation was a general one, not directed at anyone in particular. Were you assuming something to the contrary?
Not an "um" or an "ah". But a continuous unbroken flow of rational, logical information. What a pleasure to listen to. A lecturer of the highest order. Bravo!
Their is nothing rational about Sean Carroll. He is the poster boy for ignorance in science.
Stop it, he's not logical. 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
😂. O sancta simplicitas! Get thee to Hoffman😂
And with a delightfully modulated voice
He is very personable and articulate. I enjoy listening to him. Of course he is an atheist as are most physicists. They believe in one dimension only; the elemental. They do not know of or acknowledge three dimensions: Consciousness; Mind; Elements.
Consciousness being fundamental; Mind; elemental and the physical dimension also elemental; grosser or denser elements; all emerging with quantum events. That is why there is the hard problem of consciousness for atheistic philosophy and science as they see one dimension only.
Sean says that he never gets tired of being amazed at the human imagination and at Nature's stubborn insistence on following its rules of physics. But I will never get tired of listening to Sean describe how this universe works. His enthusiasm, his clarity, and his stubborn insistence on giving a fair hearing to all sides of controversies in physics is joyful to behold. Sean refuses to remain stuck in the mud of mysteries, but instead lays out the directions we can go and patiently awaits the march of science to determine the best direction.
He reminds me of the "color commentator" at NFL football games. He doesn't just give "nuts and bolts" statistics of how many yards were gained. He tells stories of the players on and off the field and how that relates to their performance in the game. We humans may understand math, but we also understand through a good story. Sean is the master color commentator, telling stories that help us appreciate the "action on the field".

I’m 28 years old. I’m not a student of any kind. I attended a few semesters of community college. My job has NOTHING to do with quantum mechanics, academia, or particularly difficult concepts. I’m just someone that loves to learn. Knowledge is a gift. The more you learn about existence the more beautiful it reveals itself to be. Every academic field, every culture, even different beliefs systems, allow more of the universe’s richness to come through. Instead of chasing one truth, learn to see the many truths that people use to interpret the world. You have one too.
Thank you Sean Carroll for spreading knowledge in a concise and entertaining way. You’re a cool human.

I thought the same as the first part of your comment, scroll and it's #1
I think it's "Dr."
I could listen to Dr. Carroll for hours. Like Brian Greene, Lawrence Krauss, and a few others I watch on a regular basis, his ability to elucidate complex phenomena is amazing.
Thinking about a comment, then looked at yours and it said exactly what I was thinking 🤔 .....Ditto
Listen long enough and you will find out how shallow these lectures are... Compilation, repetition, ego...

I largely prefer him over Brian Greene tbh. It's like he's is constantly trying to be "hip" and "funny" and to me it just feels incredibly awkward

Good one👍

He reminds me a little bit of my physics teacher for the year I had to take in college for my biology degree. I never thought I'd find physics that interesting but I did.
I like all his lectures after he hopped left at Cambridge from my perspective.

As an engineer who has always been passionate about math and physics, I was intrigued by modern physics, despite neither relativity nor quantum mechanics were part of any course syllabus at my university. I studied these subjects on the side and found them really inspiring, I would go as far as to say that they gave me a novel perspective on life itself. That prompted me to create some online courses on Udemy on Quantum Mechanics, Quantum Field Theory, special and General Relativity. It’s not my job of course, but I love talking about these topics while using some mathematics for “intuition”.
Quantum Entangled Twisted Tubules:
When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else.
In other words, you are a kid who failed high school. :-)
@@lepidoptera9337 I was pretty good actually !
@@math.physics That's what all the failed kids say on the internet. In any case, that's between you and your school. :-)
@@lepidoptera9337 I don't think a "failed kid" can teach QFT, GR or other subjects :).
I especially liked his interpretation of connecting Einstein's space curvature with quantum geometry versus energy and entanglement. That is the best interpretation I have witnessed of connecting Einstein's 'Classical Interpretation" of gravity with Quantum Field Theory. I have been looking for someone to describe a possibility and this one seems plausible.
Yeah. That was pretty mindblowing to me.
But will it be enough to make a theory of everything? In other talks he shows that gravity in the core theory equation is quantum and it is good enough to be accurate one large scale, just like relativity, but not in extreme cases like black holes etc.

One of the great communicators of our generation. I’m so glad that these have been recorded so I can share with my children.
Sean is really a great educator. He is able to illustrate very complex subject matter in a very intuitive and passionate manner. I was really never good a physics in high school esp. when it came to the math and the corresponding formulas. Yet, I feel I have gained some basic understanding of the theories presented here and in other lectures by Carroll and folks like Brian Cox, Richard Feynman and others. I am very much into the arts and I find that the arts and the sciences can inform and inspire each other. Connecting it to the real world. It reminds me of the great and beautiful gothic cathedrals that inspire but were only made possible by understanding physics.

Thank you for such a great presentation. Dr. Carroll can speak for 24 hours non-stop and I won't fall asleep! Particularly liked his version of explaining the QM anomalies - not by "quantizing" our conventional classical models, but ground up from a native quantum mechanical universe.
I’ve got forced to be all ears by his excellence of knowledge and skill of storytelling.
The quiz at the end of the lecture joke never gets old. Sean is a great orator. I am just geting into the world of Physics and am really enjoying his talks.
Wow, great lecture! I've devoted nearly half my life to studying physics, but I never really thought of it in this way. Sean both explains, at least in part, many of the biggest mysteries of physics and points to new ones. Great job!

Gravity should be updated as such: 13.3321 m/s^2 and the general theory of relativity should be this as a LAW : ((G*2073)R)) --- --- --- That is why we struggle with physics because we believe in Einstein's postulations of physics as such: ( E=m*v*3000) is the Law of Special Relativity.

I have read that Newton also was troubled by his theory's "action at a distance". He kept his discomfort to himself, because he, like others of his day, did not believe in action at a distance in physics. In this regard, he did not differ from Einstein whose Relativity did away with action at a distance. I find that Newton was, in this regard, much further ahead of his time than all other physicists until Einstein, to whom he might have said, "You know, I had been thinking along the same lines! I got as far as calculus, but I had not applied it to the geometry of Riemannian 4-dimensional spaces as you did, because Riemann had not yet been born in my day; but I knew something was wrong"
He sets up Schroedinger’s cat experiment beautifully and builds up the explanation to......multiple worlds hypothesis, when you think about it it’s not any more satisfying, now we have neatly infinite copies of the entire universe to accommodate all the possible quantum events. That’s a lot of stuff, I’m not sure this is correct, I’d like to trust him but I’m not sure he advanced the argument very much.
It is an amazing speech worth watching no matter if you love physics or you are not really interested in it. In my opinion everyone would enjoy this lecture and start to think about some incredibly mysterious things around us.
Once saw him in a hotel, introduced myself and got to compliment him about his youtube lectures. Probably was a few weeks before this lecture.
The explanation for complexity as a middle way between no entropy and a lot of entropy simply blowed my mind. Amazing amazing talk

He's incredible. Spoke engagingly for an hour with barely a glance at notes. The lady introducing him, however, could scarcely utter a syllable unless her head was lowered and fixed onto her notes.
Sean has a really good tailor in this version of the Everettian Multiverse. Looking respectable is half of the way to a successful presentation.
Nice to see that Andy Bernard who works in Dunder-Mifflin in day and teaches physics in the night.
I think the answer to the quantum mystery is just the idea of quantification itself
The universe does not have exact numbers to correspond to it what is rather always in a state of flux
An example would be saying that I'm 6 ft tall. It's just an approximation. Someone's exact height is always changing but we give an approximate estimate
This is the same with all quantification. It's only accurate within the margin of error
Height weight, any mathematical description of a system is just an approximation
In reality the electron is distributed in a cloud and always will be
But when we give mathematical descriptions of a system we're basically giving an approximation that has some utility
Therefore all the terms like superposition wave function duality, they're all just terms to give some Precision to something that'll always be Beyond quantification
It's like the shape of the Earth you can say it's a sphere or an oblong spheroid and that is more accurate than saying it's flat
But the utility is always based on a relative system.
in reality the shape of the earth is always changing slightly
Anyway can someone hit me back and see how we can get these ideas being discussed by physicists like Sean Carroll
I think what I'm saying here is a more basic idea then the many-worlds
In reality many worlds is just a an attempt to give Precision to the universe the same way we give Precision to the shape of the Earth. But in reality such linguistic terms will never capture the Nuance nature of reality. I think it's more fundamental to just say that quantification will always be accurate within the margin of error and that the actuality of reality can never be precisely described in any way that is true for all Observers.
So again the fundamental mystery or Indescribable nature is due to an attempt to quantify what is beyond quantification in an ultimate sense!

Strange how even Sean Carroll gets this wrong; In the bullet cluster the red is indeed where the mass is. However, the blue is not where the mass is but instead where the gravitation is. If the blue was also where the mass is the blue would have behaved just as the red did. Ha yes, gravitation in the absence of mass is the new conundrum of modern physics. {LIVE Science; Forums, History and Culture; Culture History & Science; What is a living individual and is it naturally universally mobile?}

THAT was a fantastic lecture. I only WISH when i did my degree they talked about entropy as information - when i realised that, it kinda clicked! And that when he jokes about "i swiped my arm because the glass was going to fall", thinking about entanglement first, intuitively is backwards, since our whole life experience is centred around us, it was insightful.

@@ccahill2322 great! We take what meaning we can.
this is an Incredible Documentary and i could listen to Sean Carroll for hours, he explains physics in such a way that even if you don't know anything about it '' you will understand what he is saying, *
Sean is a great exemple of an open minded scientist, it is very nice to see.
Krauss or Neil Degrasse Tyson on the other hand, are the perfect examples of a close minded scientists, almost religious in a sense. If he's asked a question he doesn't know the answer, he will tell you : Look, I can measure the phenomena, if that is not enough for you, you can stay here playing with your '' Whys '', while me and my colleagues continue to go forward. He will then look at you with the most ... arrogant face in the world.
Which to me is unnaceptable, in the scientific world. So I totally believe Sean when he says that the scientist that was asking questions was ''gently'' tossed away. Sry for my bad english.
I totally agree with you. A lot of famous science personalities will quickly say, “that’s not my field, go somewhere else for that.” Yet, science in general has colonized other domains of knowledge. Science is the new cosmology and philosophy. The scope of science is accurate but limited, you can’t encapsulate the world with just science; nonetheless, they keep trying.
It's good seeing Sean finally coming into his own skin and accepting the fact that he is responsible for enticing the next generation. Thanks Sean! 💪😎🇺🇲

How to trivialize a great speaker..grow up
@@corneliuslinneball3785 what... how is that even related. It's just a fun moment in the lecture.
Does anyone feel that our cross-over from classical to statistical mechanics may have brought us astray? Statistics summarize observations. Statistics shows your the louds, and how clouds move; it don't tell you how the clouds were formed. Statistics can give you intuition, and narrow down theories. But I feel like we are stretching stats to a dimension of abstraction that we've come so far, that we've convinced ourselves that the equations that can explain statistics, are somehow reverberations of the underlying classical truths. Although I find this an insightful path, we must not give up on the pursuit of there being a classical description that we have not yet accounted for the variables for.
31:00 Finally we see the casual photo of Everett!
Sean wanted to put this in his last book but couldn't secure the rights. He had to use the same straight-laced photo that appears everywhere.

Maldacena conjectured that the whole universe is QC function evolving from a single wave function. Phase transition of non-life matter to life and consciousness is also a QC function.

Addendum :
Some more CRAZY question / points :
1) Electron is spinning!
2) Proton is vibrating!
3 ) Both make
neutron/s chargeless!
4 )Electron keeps everything entangled as well as in order or in disorder (entropy)!
5) That means electron photon interaction... may help us to understand the theoretical points :
a)
The -e- is there, when we look at it...and not there, when not looking at it... right...!!!???
Therefore the above points may also suggest the ELECTRON being part of the classical science and photon being part of the quantum science...could lead us to the territory of GUT...!!!
That means all the theories of all those famous Scientists are the contributors for the present TOE and GUT... in micro and macro levels...
A BIT- BY - BIT...!!!
THANKS AGAIN DR. SEAN CARROLL...!!!
When even the Chair of Physics at Cal Tech struggles to explain entropy (hint: an egg is never a good example), we need more clarity on the concept of entropy.
Entropy is defined as dS=deltaQ_rev/T. What in the world is hard to understand about this? A simple interpretation of entropy is the amount of heat energy in a system that can not do useful work (on an external system).
I love listening to Sean Carrol. ❤
December 24, 2020
One of the best I came across...... Outstanding.
Thank you Darwin College for this excellent upload, with Dr. Sean Carroll.
@Bertrand de Born WOW! Somebody deeply hurted you to make you so angry....but you and some others are the MEN who found out the TRUTH about modern physics....LOL.
I am a layman. I have a relatively limited education, but it seems to me that gravity is such a surprisingly weak force because it is diluted if you will and spread across all the "many worlds" or possible states. The other forces are not and are local to each possible state.
Sorry, I'll show myself out . .
That is actually one of the concepts out there, but the standard idea is that it leaks from our "brane", meaning our 3D/4D slice of a higher dimensional object, into those higher dimensions. It's more related to a multiverse idea stemming from String theory, rather than the one stemming from quantum dynamics (but these might turn out to be one and the same, or both active, or both false).
What I wonder about is whether the notion of a quantum multiverse fits in that String theory perspective. On the one hand yes, since one could argue that the quantum bifurcation of universes happens in another dimension. On the other hand no, because bifurcation is fractal, instead of plane-filling in nature.
If you're right, one could imagine then that if the universe wouldn't split, gravity would be stronger, because it didn't leak. We could perhaps test that in a bubble of Bose-Einstein condensate. Perhaps we would see that gravity is altered inside the bubble, being stronger than otherwise expected.
@Ahura There seems to be no explanation as to why gravity is such a weak force. My guess, if correct, could explain that. String theorists have a similar opinion based on far more knowledge than I bring to the table.
@Ahura Look it up but there are only theories and guesses. I can't see how any of this is testable or how any experiment could be devised to prove it. It seems strange that only gravity would be constant across all dimensions/worlds/branes but if true it would explain why gravity is so weak.
@Ahura I just found this. It's a very short video but might wet your appetite to look outside classical physics. I am really out of my depth here and only class myself as "fascinated." th-cam.com/video/s7Babitv4Fg/w-d-xo.html It's a 4 minute clip from 2008 and only speaks of one other parallel universe. Sean Carroll (who's ideas fascinate me the most) takes this much further and theorizes about infinite universes.
But all the forces would be spread out to the other worlds too? By that logic, I don’t think it’s useful to think about the other worlds of the multiple worlds hypothesis as having any effect on our universe, they are disconnected from us are they not?
I totally agree with Joe Gelman below. Sean Carrol is brilliant and inspiring teacher exactly in the tradition of the Great Richard Feynman in whose chair Prof Carroll actually sits both metaphorically and literally as he often points out at the beginnings of his talks. I have some his books in audible format simply because I like the sound of his voice. His proof that Death really is the end (see the youTube video) inspires one to live this one to the full as its the only one you'll get. Of course, if we are simply running as simulations in our own future descendents' super-computers then let's hope no-one switches the power off which would amount to the same thing.
"Nearby is just, a colourful way of talking about, the amount of entanglement between abstract quantum degrees of freedom." Sean Carroll
*of empty space!
You know, the original "Freedom's just another word for nothing left to lose" still makes a better lyric.
This may be profound. It is easier to move through time than space. So "nearby" is preferred. The fastest you can go through space is 45 degrees on reference diagram(speed of light). But 90 degrees of range is available in the Time direction (2x45). SC knows Relativity, so i wonder what implications he may be making?
How do they explain craft with propellantless propulsion?
Patrick EH how do you explain it? I want to see one
@@ale131296 The military has MANY videos showing it. Many different countries airforces have recorded it. Look them up. Why would I need to form a theory on how it works? Shows you do NOT have a science degree. Why would the person who discovered Extra-galactic CRBs need to explain how they appear to violate E=MC2?
@@patrickeh696 Show me the videos then and the formula is not E=mc^2 but E^2 = p^2c^2 + m^2c^4
I'm a physicist so I pretty well know how this works. YOU show me the unicorns you're talking about
@@patrickeh696 You're a Goddamned Liar just looking for attention.
Always enjoy your talks, but this was one of the best. Thanks!
Memory formation is an entropic process. Ink to paper. Bit on CMOS. Synapse strength growing. All have an energy cost and energy waste. This is why we remember the past, because to commit a thought to memory is to consume and dissipate energy. To store a bit into SRAM is to take a burst of energy and turn it into heat, raising the temperature of silicon. No need to use "past hypothesis" to explain the arrow of time in terms of human experience.
This is the first lecture regarding quantum mechanics that I can fully understand. Truly remarkable.
still they cant understand the cosmos nither QM. seems we are just in medle space of them.
Surely we are still pursuing the truth, but this man makes quantum mechanics much more approachable.
@@ingathrise He is good at speaking ideas as well clear to me but are they in the right frame?
@@SernasHeptaDimesionalSpace If the theorem can be theoretically proved in a closed loop backed by axioms, that'll be a good enough thing. For now, it's more like metaphysics, indeed.
@@ingathrise Math works well to understand QM as well the cosmos but it does not look that they are in the right truck or right frame, if every thing is made of light then matter must to be acomodated as the rainbow shows, even light follows atomic waight why not matter?, Einstein, Hubble as well Neuton might be right at the yellow level that we are but as soon we look out to another level they are out of the game because they must to recalibrate to that level. - In quantum mecanics light aplies cause the photon is still light even if it is in the form of a cloud still is light and cant be at all places cause the north are gaseous and south are rocky ones same as our solar system that the inside circle are made by the 4 rocky planets and the gaseous are made by the 4 gaseous ones, the sun is the neutral part as well is the bottom of the system cause we all go in levels even stars. - I do have my channel based in colors as the rainbow based in a Mayan Callender as well a DNA picture.
Recomend you to see the video: HOW GOOD IS THE EVIDENCE FOR DARK ENERGY? you might be surprised. If Dr Subir and team are right then my work make sense by speaking of levels, my guess from all I have done is that they will be correct.
This guy is fantastic and maddening at the same time.
...and so is his talk... Now I got a headache. I'm just a poor chemist - without Ruherford's atom model I don't even have a job!
Sean is the man!
What an exceptional communicator Sean Carroll is. And to think, it’s only his side job.
thanks, Sean, for the splendid lecture on the basic problems of modern physics. surely, understanding of life is fundamentally inportant and can give us a key for the better understanding of quantum mechanics and of our physical reality as a whole (as well as of ourselves in this reality, i guess))
Finally, a smidgeon of comprehension comes my way. Excellent lecture.
I love listening to his lectures. Such a brilliant man. Judging by his choise of suit and tie he clearly aims at maintaining a low entropy state in style for much longer than Einstein.
One could argue though, by viewing tieknots as a self avoiding random walk on a triangular lattice (see www.tcm.phy.cam.ac.uk/~tmf20/TIES/PAPERS/paper_nature.pdf), that a state of even lower entropy could have been achieved by tying the tie into a "Oriental" style tieknot (a tie knot wich requires only four moves: left, right, center, tie), instead of what looks to be a (very stylish) "Half-Windsor" (requiring seven moves: left, right, center, left, right, center, tie).
On the other hand, a Half-Windsor looks tidier, so that may make the Sean Carroll system as a whole at least appear less entropic :P
@@impactguide I like that your joke links to a nature paper
My biggest question is: if we are governed by the law of entropy, how come evolution took place? Evolution is not random, the fact that at one point in time atoms bonded into molecules, then protein chains then cells and organisms now so amazingly complex, doesn't look like entropy to me... so I don't believe in entropy. There must be a reason behind why particles decided to become humans who study particles, and not just dance along in space ever more chaotically.
My socks are also in superposition (each of them is both left and right at the same time) until I put them on)))
Actually that's brilliant
😌
I once quoted Mitch Hedberg while TAing an intro to electronics course because students in the lab couldn’t tell me what a “resistor” does.
“I wanna have a job in the ‘kitchen appliance naming’ industry. That seems like a cool job to me. Toaster, blender, refridgerator.… just say what the thing does, and then add ‘-er’!
What’s this thing do?
It keeps shit fresh.
Well, that’s a fresher. I’m going on break.”
Crickets. My delivery was so bad.
Atoms are like Toy Story's characters, when nobody's looking they have their own life, when somebody looks they stop.
ANDY'S COMING!
Or like that ghost in the Super Mario games
That's a good explanation of the universe and beyond!
You just perfectly described my ding dong.
Ha!
Sean Carroll and Brian Greene ... even I understand now the basics of QF... great speakers!
Ah yes. Quantum fysics.
* nice Mitch Hedberg reference. My man!
Science Kermit is best Kermit.
Seriously though, I'm become a big fan of Professor Carroll as a science communicator. Hope to hear much more from him in the future!
My man!!!
GRAVITY EXPLAINED, universe is made of minute cells once contained in a universal
shell that was broken or deformed by an external force.
this produced expansion creating a true void that must not exist,
leaving the cells to expand or split,I believe the destruction or
splitting of cells is where all matter originates,
therefore all the contents of this universe will become matter
and the universal matter will disperse or be contained
by an outer external force or medium.
The cells must penetrate already created matter to a degree, becoming harder the denser it is, until it is so dense it is impossible. thus the push back is multiplied infinitely
causing corresponding gravity push...
As far as so-called gravity it is plain to see that there is no attraction, only an external push
forcing matter together .
Imagine an oil filled rubber ball each molecule of oil must have the same force upon it.
Then introduce a foreign particle of the same size and density then each molecule will have slightly
higher pressure upon it nothing will coalesce
then add a larger or denser body with larger or harder surface to be pushed upon by the other molecules
all the molecules will feel a small amount more push but the nearer the large body cells will get pushed harder.
[this energy really comes from the constant push from the ball membrane or what exists outside it]
then introduce a smaller dense body in the vicinity of the harder pushed cells.
if the number of hard pushed cells behind this body is higher than the ones between it and the large body then gravity is achieved,,,unless the pull from the expanding universe shell is greater..
Without resistance to these cells energy would not be forced to navigate a wave pattern,
the cells would not become excited and light as we know it would not exist .
Energy waves passing through harder pushed cell formations will deviate around
the reason they are pushed.
Hard pushed cells may be deformed from a sphere into an ovoid making it harder to rotate,
also making energy travel differently
The universe itself may be such an ovoid thus the reason for expansion.
Magnets must electronically rearrange the cells shape and alignment making the rearranging object harder or easier to navigate between depending the manufactured configuration.
As far as Quantum physics goes we do not have any real data so mathematical
physics is applied and comes up with sometimes fanciful answers to fit a paradox.
Understanding a data lacking subject has always failed people already in this
field would do best just striving for accurate observation as some early astronomers did.
An understanding will develop with detection instruments and supercomputing enhancements ,
seeing it first hand. some bright spark will discover the bleeding obvious and mathematise it.
We must determine the size and density of each cell by measuring each light wave
in relation to one another ,and the number of cells between each crest
and finding the correlation that would fit all known energy waves if this can be achieved, the next
step must be to create
corresponding energy waves before a moving object creating an air in sand effect thus help said object closer to the preceding wave speed
Initial measurements should be simple two dimensional with known wave patterns overlaid on the same plane and begin with spherical solid cells filling the voids between the crests of all waves.
First, hoping all the energy waves respect the integrity of each cell, if not some types of energy waves
may penetrate part of the cell, as do they penetrate some matter.
black holes are remnant void bubbles still trying to eliminate the space where cells are absent,destroying surrounding cells and creating matter and drawing existing
matter to fill the void .billions may have succeeded leaving small super dense spheres but most can't keep up with the constant universe expansion and will take all
their surrounding galaxy and more.
No matter how beautiful and pleasant maths is , since the mid 60's, it has blinded physicists
before then a physical notion was envisaged then came out the ruler to see if it would stack up.
These are some answers to how things unfolded but surely the harder question is why.
Why has life evolved to a stage that we can pose these questions?
Surely non existence would be the easier option ,without struggle without knowing about
your inevitable destruction personally and universally this question is the real puzzle.
This is why the emergence of conscience coincided with a genetic predisposition towards
a god culture everywhere on earth ,a genetic valium so to speak.
which must be ameliorated not railed against by atheist dissenters , its just DNA evolved a part of
our bodies to believe so as to survive longer.
The answer can only be chemistry ,all life is simply a chemical reaction , the same as the
stars react with each other ,no matter how complicated its components become it must rely
on the basic building blocks to exist ,my thoughts while writing this are governed by
a chemical reaction and the lightning created by the reaction.
Therefore if matter has no will and the meeting of different types of matter will react
differently then the meaning of life has the same weight as mixing paint ,life and death is
eventually inevitable wherever matter coalesces .,..
Math, like numbers, is a language humans invented to describe relationships more usefully than words. It chokes me when people talk about math like it's something discovered that was used by god(s) to create our universe (if it is a universe).
Serious question: when we talk about quantum mechanics, I imagine... stuff... that is so small it is impossible to see with thr naked eye, so people use machines to "observe" particular (re)actions. So what does he mean by "we don't know why when we LOOK at it, it doesn't act like a wave" ? Clearly the act of observing, done through a machine or whatever experiment they're doing, acts upon the quantum element and changes the way it acts when "observed". So I want to know how do they "observe" the elements without affecting them?
Love S.C but this is the same lecture now for a decade...we need some new science!
Look at it like a textbook. Text books don't radically change they get updated
He is updating it a little bit and clarifying and enhancing butt, it's the same basic textbook of information.
Milan Siroky that's why you should think for yourself!

So this belief of Evert and Sean of many worlds exists as a reality in at least one universe?
Wow! Hope I never find myself there. I like my universe; where physicists who can't figure something out just B.S. there way through it.
I like my universe as well, as it contains many amusing things. It is always fun to encounter those who are attempting to communicate a thought in writing but are unable to spell properly or use correct punctuation.
DogGambit ha ha perhaps you're right. Maybe out there somewhere there is one universe where the field of science is NOT filled in and about with excessive numbers of pompous asses, clearly not mine as you so amply demonstrated. Eh! eh! _Got my _*_thought_*_ that time!!! eh!.._ ..:-)
@@4pharaoh - Of course I'm right, because when I said "It is always fun ...", I meant it is always fun for me, because I'm a fun loving guy. I can't claim to know about others. Claiming to know that would be pompous. Also, my observation was a general one, not directed at anyone in particular. Were you assuming something to the contrary?
