I see a lot of parallels between string theory and climate science. At least there is beautiful math in string theory.

​@@averybrooks2099 are the parallels that both are based on data? What parallels do you see?

[@havenbastion]

Being a football coach shouldn’t preclude someone from teaching math

[@calebrochester9516]

Ironically I think that high school was above average compared to lot of other other places. You do the math then. The worst math teacher I ever met was also the football coach. It’s just coincidence then. I’m assuming that he was better at coaching the football team than he was at teaching me calculus, or whatever that was. I wouldn’t know, cause I didn’t play football. I didn’t watch the games either. I avoided the pep rallies like the plague. All these years later the use of that math comes up in the science videos I watch.

[@taylortrzeciak7572]

Spacetime being flat is just the idea of being confined or restricted in how it exists, simplistic, but not incorrect in the outcome the idea was trying to convey. Positive cosmological constant and dark energy are synonymous, both are the actual restriction and confinement for the spacetime continuum (aka limited growth/expansion allowed). The Spacetime continuum theories to date could be perceived as accumulating digestible information to build up to the idea that there are restrictions, like a simplistic building block, or conversely a heuristic approach pulling from deeper incommunicable knowledge, depending on how you think about it. Either way, cosmological constants and dark energy are barriers of control that do restrict and confine Spacetime, more specifically to not surpass a certain expansion.

[@DarwinianUniversal]

Why do you need quantum gravity when atomic mass is generated by Glouns, which are a type of light, when we know that light has the capacity to propel through voids of space. Why don't you see that Mass is the property that is accelerating matter in a gravitational field. Atoms possess the agency that drives gravitational acceleration

[@saltycreole2673]

Whatever happened to Verlinde's Emergent Gravity Theory? That gravity is an emergent force involving time rather than being one of the four forces. Makes better sense than a Quantum Gravity Theory.

[@kevinmcfarlane2752]

Coincidentally I was just thinking that the idea of quantum gravity doesn’t seem to make much sense. General relativity says that matter and energy cause gravity by curving space-time. So it’s a fundamentally different thing than the “stuff” that is governed by QM. I’ve never heard of the theory you mention but conceptually it sounds more reasonable.

[@JM-nt5fm]

Yeah, this stuff is nonsense. Much like when anyone uses condensation fields to conveniently tidy up mathematical equations. Gravity IS emergent because it is part of the relationship of mass and energy. E=mc^2 was never the complete equation and it is oversimplified for general consumption. Time and Gravity are interrelated. Once you understand this the idea of quanta of time or gravity just doesn't pass the sniff test. With that being said quantum theory has many aspects that on initial inspection are abhorrently illogical but bare out in experiments. So what is the absolute truth never possible to predict with 100% certainty. At this point Verlindes feels more correct.

[@carlosgaspar8447]

he's still presenting his theories with updates (and quoting ed whitten). one uploaded about 4 months ago. but his theory relates to information/entropy and how equations resembling GR can be derived using those concepts.

[@HolyMith]

@@kevinmcfarlane2752 Well it's not that nonsensical. Matter and energy are precisely the "stuff" you are talking about. Evidently, they must have some interaction with the spacetime around them in order to change its geometry. The problem Quantum Gravity encounters is that on the particle level, the magnitude of that effect utterly vanishes, due to the warping being very weak and requiring phenomenal amounts of mass-energy to be measurable. This is partly why black holes are of such interest. At the event horizon, we see a very clear gravitational phenomenon, which instersects with quantum physics when you ask what particles behave like on, or close to, that boundary. Additionally, the question of the sungularity undoubtedly involves quantum mechanical effects due to its compact size and it's relation to the event horizon. Hope this helps.

[@siddharthprathmpant]

I was just effing around with chatgpt - The hypothesis regarding the theory of darkness states that darkness is composed of particles called "dotons" that travel in the opposite direction to photons, at a speed of negative c in a vacuum. This theory suggests that the duality of wave and particle nature of light is actually just the existence of darkness as a wave when light exists as a particle, and darkness existing as a particle when light exists as a wave. The hypothesis also proposes that black holes are made up of darkness, not light. The hypothesis suggests that the negative direction of travel of dotons, in relation to the speed of light, is actually the opposite direction of time, i.e., light travels into the future and darkness travels into the past. The observation of light is the result of time ticking forward, while the observation of darkness could lead to time ticking backwards. The hypothesis also states that the flow of photons creates a gravitational field, and the flow of dotons creates anti-gravity. Additionally, the hypothesis suggests that the big bang was actually caused by antigravity generated by the excessive amounts of darkness or dotons traveling towards the singularity.

[@TEKim-lk6op]

So to visualize. The present moment may look like the centre of an infinity sign and one loop is dark waves traveling back in time while photons are in the other loop traveling forward in time. Is there the proposal then that dark waves are dark energy and dotons are dark matter?

[@MrGundawindy]

I want to spitball an idea about dark matter/dark energy to someone that may understand the math. I'm sure you're aware of the picture representing the gravity well of a massive object, like a sheet with a weight on it. But what about if massless space time is curved inn the opposite direction, not flat? Such that in the deepest, emptiest parts of space time, gravity is actually repulsive. In more massive areas, like the empty space in between galaxies somewhere is flat (actual zero gravity) and near massive objects the curve is the well, which causes an attraction?

[@probably_crater]

I think that is the current theory, but I've never heard it explained like you did.

[@MrGundawindy]

@@probably_crater really? I've never heard that, but I figure we really don't understand how gravity works and we definitely don't understand what this dark matter and dark energy is.

[@GangstaCemetery]

The problem is gravity isn’t a force it’s an emergence that’s needs certain factors , if particles are massless you won’t find gravity anywhere

[@Gicopiro]

that's not true, gravity comes from energy and/or mass

[@MartinLear_CChem_MRSC]

String theory is, indeed, a good skipping rope to train our minds in the general direction of unifying “the force fields”, but contextually I do not think of gravity as a similarly dimensional “force” - maybe that is one of the problems.

[@robinsoncrusoeonmars8594]

This was so interesting! Thanks Les and Andrew. The history of the theories is what to me is the most interesting. As Andrew talks about the each theory's progression, it occurred to me that what they are actually doing is discovering a better explanation of the information that already exists in the universe. But all the information of the universe is always there (unless is it making new information?), and we are just discovering it. We are not changing anything, but rather just getting better and better explanations of the perception (our observations) or description of the universe. The hologram/holographic plate theory is really interesting, again giving us the perception of what is reality. Wow, lot's to think about! Thanks again Les, very intuitive questions.

[@showmewhyiamwrong]

As I listen to this discussion, I wonder, as I have for some time, about the possible direct connection between the rise in the number of, and size, of black holes and the rise in the amount of DE and DM. If BH have any purpose in the scheme of things it may be that they are the Factories where ordinary Matter and Energy are converted into DE and DM.If so then it follows that there should be a direct correlation between the number and size of BHs and the amount of DM and DE over Time. Since we now have Time Machines in the form of Powerful telescopes that can look back at the early Universe, it may be possible to measure such a correlation if it exists. This would mean that the “Information” that falls into a BH is not lost at some singularity or stored at the EVH, but is fed back into the surrounding Spacetime. The process, if it occurs, should leave some detectable trace of its existence in the immediate vicinity of the BH and should be more detectable around a SMBHs.

[@jr8209]

what you weren't blow away by all the handwavy explanations presented by Michio Kaku with neat graphics?

[@jessejordache1869]

As the guest said, "We don't know what, or if in any sense, string theory describes the world". IoW, there are theories and Theories. The former are loose attempts to describe phenomenon that haven't been subjected to the the scientific method; in the case of string theory it's not even clear how you could do such a thing. A better example is in quantum mechanics: you have two major competing models (the first is WAY more popular): The Standard Model: "It is what it is. The universe doesn't care whether or not you're comfortable with its non-determinisml" de Broglie-Bohm Model: "We are NOT comfortable with a non-deterministic universe. And if you look closely, the scattering of outputs from a quantum wave behaves like bubbles on surface tension. Here's some math which shows this more rigorously than words can. Non-deterministic predictions coming soon, we hope." If de Broglie-Bohm is ever strengthened to provide greater accuracy than the standard model's distributed prediction, it will become more widely accepted. But you're asking a higher degree of prediction for just one theory to be considered on par with the other. So I dunno, pick one. But until you're mathematically sophisticated enough to follow the arguments as equations, you're doing physics-by-analogy and have a distorted view of the whole thing. So naturally, what it feels like to you isn't really an argument.

[@nighttrain1565]

@@jessejordache1869 what "feels like" is what determinism gave way to philosophy which gave way to math, laws, social hierarchies, and the languages, governments, and nearly all structures by which Modern Life is governed.. All of it is from philosophy. Not math. I am of the opinion and the feeling that philosophy in and of itself creates language expands mathematics and current thinking. It isnt the math that progresses, it is the understanding in the philosophy of which describes everything that gets ushered forward. The math follows the concepts. I'm not arguing whether or not this is right or wrong but it is what it is and it's just a system that can never understand itself. It is the anthropic principle. We are products of the system therefore we are incapable of devising systems to understand the system of which we are a product of. This is a philosophical law that supersedes any mathematics. Unfortunately it is what it is prevails over math lol

[@jessejordache1869]

​@@nighttrain1565 Well written. Okay, three points -- actually three and a half points: first, and most importantly, we *are* talking about Quantum Gravity. Second, what makes you think your intuition is less a subject of anthropicity than math is? Third, the argument about language and mathematics and what-precedes-what is well taken, and sort of unanswerable. In other contexts I have to constantly argue that elements of mathematics as basic as a contiguous number line are distortions of reality -- that in the actual world, you cannot zoom forever into smaller and smaller numbers, or subsets of the mandelbrot set, or whatever; you will eventually run into particle physics, and you have a hard limit at the Planck constant (but your zooming will bog down long before that). And there's irony, using a mathematical expression to argue that mathematics is distortive. But if so it's a double irony, because it's people's intuition that drives them to accept the great abstraction of mathematics as physically real in the first place. One of the indicators that Quantum Mechanics is involved is when things stop making intuitive sense: Schrodinger's Cat is a thought experiment involving a cat that is both dead and alive until someone observes it (that the cat can't be the observer is IMO a failure of imagination, but you can posit an egg that's both whole and cracked open if you like), and it was formulated in reaction to Schrodinger's equation. In other words, the man who formulated the "E=MC^2" of the quantum world's reaction to his own discovery was horror. It didn't stop him from publishing it, and the relation between the quantum waveform and general mechanics that it describes is where the rubber hits the road on... everything. It is, as of right now, experimentally and mathematically bulletproof. And a bit of a mindfuck. At the moment, the acid test of "the universe cannot properly understand itself" vs "2 + 2 = 4" is this: science makes things happen. There was an explosion of a magnitude unseen outside of astronomical events, and of a type -- a fissile critical mass -- that had never occurred anywhere in the universe, ever. It was over Hiroshima, Japan, 50 years before I was born to the day, and mathematicians (the word physicist didn't come into vogue until later) were able to predict the output in watts, predicted weeks earlier, with an error amounting to a fraction of a fraction of a percent. It's old news, but the fact that fissile explosions don't naturally occur, ever, and yet... still has the power to shock. At least for me. Now the half point: I think language precedes philosophy, that humans talk, and that's what makes them human, and they cannot stop talking in grammars any more than they can switch off their own binocular vision. But that's a completely different conversation. 😀

[@nighttrain1565]

@@jessejordache1869 dammit, my entire Schrodinger's cat point isn't in my last comment but I pretty much said the same thing about Schrodinger's cat, don't know why it's not there lol. Universal punchline? 😅 I understand what you are saying but i actually don't agree lol. Have you heard of gauge Theory? I'm not sure if I have it completely right but beginnings and endings are illusions of different subsets of gauges essentially and that we have limitations on what we can consider infinite in both directions of the very small and very large. I don't believe in size. I don't believe that you keep looking smaller you enter the quantum world. I don't believe in quantum world period really. At least not in the sense that modern science defines it. I think the entire field is an expression of how incomplete our math and languages are and always will be. I don't think we will ever understand the quantum world because it doesn't exist and what we are playing in is a world of broken Math that we are translating to quantum physics which isn't actually a thing.. that's like a huge problem to me that we live by two different sets of realities and two different sets of mathematics and they don't agree? And then people pretend to have an understanding of quantum physics? Pretty hysterically arrogant. A lot of people have a problem with this Theory but I can guarantee you with 100% certainty we will never have Quantum computing in our lifetime😅. Very weird that I believe an entire genre of science is a fuck up that nobody has bothered to correct because everyone is scared of saying no, this philosophically does not line up. Nature is in fact natural and if we cannot Define nature naturally we must lack the capacity to. I could tell you a swordfish plus a moose equals a monkey and create a digital software within a world that makes these conditions true but it doesn't make them true just because I barricaded a world for them to work properly as conditions in. The entire science of quantum physics is playtime science. Sometimes somebody will come along with an entirely different proposal as to what is going on and it will merge mathematics and bring us a unified field Theory but until then, lets see those quantum computers give me 2+2=4 without giving me 10 to the 24th wrong answers first lol

[@feynmanschwingere_mc2270]

"Untranslatable." Is a massive overstatement. Yes, the math is crucial and integral, but language is even more fundamental than mathematics (as Russell's paradox shows). We derive ALL truths from analogy. Even mathematical truths. Physicists discuss stuff in words too. (Speaking from experience).

Andrew and Lex, Quantum Gravity and the theory, mathematics, laws, reproducible experiments and observations that underpinned it, is crucial for an empirical real true Quantum Theory of Gravity that would finish Einstein's Revolution in physics. Problem is that, since the 17th century up to the present, the Mathematics that we have so far cannot solve the problem of quantum gravitation. Mathematics is invented and discovered. That's my personal experience. I've invented/discovered a completely new mathematics in the course of my 30-year-long basic research on Quantum Gravity in Singapore. I called it Majulah Matematika in honour of my home country Singapore. I use it to solve one of the most difficult conundrums in physics- the True Nature of Gravity. Here is one of the many solutions that my new mathematics has derived: A Computer Universe that is real. It is run by Quantum Gravitational Computation, Quantum Gravitational Entanglement and Quantum Gravitation covering the entire Universe. An empirical Theory of Quantum Gravity is the key. And it will led us to understanding of how and why Gravity works. It will also at the same time, debunk and invalidate String Theory, Loop Quantum Gravity, M Theory, Theory of General Relativity and all failed and wrong theories of gravity. But it will proved and validate Einstein's Hidden Variables and EPR's authors Einstein, Podolsky and Rosen correct. The Hidden variables are: Quantum Gravity, Quantum Anti-Gravity, Quantum Neutral Gravity, the macroscopic cosmic scale Gravitational Quantum Entanglement and Gravitational Quantum Computation. All these would complete the Quantum Foundation, Unification of Gravity with Quantum Mechanics and the realization of Theory of Everything in Physics. I have discovered and cracked the code of the true nature of Gravity in my over 30 years of basic research works in Singapore. This discovery/invention/theory of mine include THE GOD EQUATION - THE TRINITY Equations, Laws and Codes For QUANTUM GRAVITATION , QUANTUM GRAVITATIONAL ENTANGLE MENT and GRAVITATIONAL QUANTUM COMPUTATION that pave the way for Theory of Everything in Physics: - THE 3-in-1 HOLY GRAILS of Physics: 1. Quantum Anti-Gravity/Spin Up Quantum Gravitational Entanglement/0 Rhu Bit or R Bit: QAG = ∆QGOρ < ∆QGFρ = ↑α 2. Quantum Gravity/Spin Down Quantum Gravitational Entanglement/1 Rhu Bit or R Bit: QG = ∆QGOρ > ∆QGFρ = ↓α 3. Quantum Neutral Gravity/Superposition Quantum Gravitational Entanglement/01 and/or 10 Rhu Bit or R Bit: QNG = ∆QGOρ = ∆QGFρ = ↑↓α We now have a working Quantum Theory of Gravity that is testable and complete with reproducible empirical experiments with the same results if repeated over and over again and again, confirmed by empirical observations in nature with 7-Sigma level results, guided by empirical Laws, Cosmic/Universal Computation and physical/mathematical Trinity God Equations that are predictive, precise and does no collapse even in high energies of Big Bang and singularity of Black Hole. FYI: Quantum Gravity or Quantum Gravitation have three types that are equivalent to and manifested by Quantum Computational Gravitation- the biggest and most powerful Computer Software Program and Hardware in the Universe and Quantum Gravitational Entanglement - a Quantum Entanglement at Macroscopic Cosmic Scale namely: 1. Quantum Anti-Gravity = Spin Up Quantum Entanglement State; 2. Quantum Neutral Gravity = Superposition Quantum Entanglement State; and 3. Quantum Gravity = Spin Down Quantum Entanglement State.

Second Law of Quantum Gravitation: Rovira’s Universal Law of Quantum Anti-Gravity. “The lesser mass density of gravitating Quantum Objects than the Quantum Gravitational Field causes an upward acceleration of the Quantum Objects in a Quantum Gravitational Field instantaneously mediated by Graviton.” -Roel Real Rovira Equation for Quantum Anti-Gravity/Spin Up Quantum Gravitational Entanglement: QAG = ∆QGOρ < ∆QGFρ = ↑α Where: QAG is Quantum Anti-Gravity in Rovira (value of upward acceleration force due to quantum anti-gravity) in kg. ∆QGOρ is Differential Change in lesser mass density of Quantum Anti-Gravitating Objects than the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↑α is the Resultant Upward Acceleration of Anti-Gravitating Quantum Objects in mtr/sec. 3. Third Law of Quantum Gravitation: Rovira’s Law of Quantum Neutral Gravitation. “The equal mass density of gravitating Quantum Objects and the Quantum Gravitational Field causes a zero acceleration or floating or hoovering of the gravitating Quantum Objects in a Quantum Gravitational Field, instantaneously mediated by Graviton.” - Roel real Rovira Equation for Quantum Neutral Gravity and Superposition Quantum Gravitational Entanglement: QNG = ∆QGOρ = ∆QGFρ = ↑↓α Where: QNG is Quantum Neutral Gravity in Rovira (value of zero acceleration force due to quantum neutral gravity) in kg. ∆QGOρ is Differential Change in equal mass density of Quantum Neutral Gravitating Objects to the mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ∆QGFρ is Differential Change in mass density of Quantum Gravitational Field in kg/m2 or g/cm3. ↑↓0α is the Resultant zero acceleration or non-acceleration of Neutral Gravitating Quantum Objects in mtr/sec.

The problem with quantum gravity is that he math always ends with infinity. if infinity shows up in your math, your math is wrong.

[@BROWNDIRTWARRIOR]

Flash forward a year here and it would seem like String Theory is in a bit of trouble according to the architects themselves.

Couldn't u take the size of earth vs gravity Strength. Find thr ratio and do the math and scale it down to the quantam level? And the Higgs needs its companion particle, it's 2nd half.

I wish I understood why the universe is considered to be flat.

[@josephsgountzos1702]

@BoManton Please forgive me for any possible errors in my explanation, but the reason why the Universe is considered to be flat is because the matter distribution in the Cosmos falls within the so-called "critical density". So basically, in Einstein's General Theory of Relativity which describes what we feel as gravity as the differing geometry of Spacetime, the Spacetime fabric is flat until there is a presence of matter that would curve it. Now matter is spread throughout the Universe, according to observation, in a greatly unified way where it is both evenly distributed and of a similar value of mass (the technical way of saying this is that on a macroscopic scale, the Universe is homogeneous and isotropic). This uniformity of matter is helpful for physicists to understand the overall shape of space because when you take Einstein's field equations which explain how matter curves spacetime, there is a solution called the critical density, which is 10 -26 kg/m3, and what it is saying is that if the matter distribution per cubic meter of the Universe falls within the critical density, the Universe on the largest of scales would be flat; if the matter density is greater than the critical density, then the Universe would be spherical shaped; and if lower, then it would be shaped like a saddle (known as hyperbolic space). So by observational analysis of the Cosmos on a grand scale, and from the Uniformity of the Cosmic Microwave background radiation which suggests the uniform spread of atoms as formed in the early Universe, it appears likely that the matter distribution falls in the critical density which, according to General Relativity, would show that the Universe is considered to be flat. I hope that helps!

Does it mean that every time an object falls into a black hole, it falls through a set of new plank points (or just adds a new area of plank points), as no particle, no quark, no anything would ever carry itself into the black hole through a plank point already on the black hole? And would that mean that the plank point would somehow be customised, so the information of the object is never lost?

[@jessejordache1869]

Surely you know that that's a currently debated topic, although I've never heard it formalized as "custom plank points". There ain't no such animal. It's not even clear whether or not Planck's constant has any relevance in a singularity, as things like "angular momentum" would be meaningless.

[@advaitrahasya]

Lovely description of the cleverness involved in finding relationships between the various mathematical models. Mathematical models though, are not, in their nature, descriptive of the mechanism which gives rise to the appearances which the maths can be tweaked to fit. What physics seems to have been lacking is an explanation of the mechanism by which the phenomena they measure arise in the first place. Boyle's law does not describe the mechanism whereby pressure arises. Epicycles did not yield the Copernican understanding of orbital motion. True advances in understanding simplify the picture and explain why the mathematical models work. Isn't it time to start considering what gravity, fields, forces, dimensions and the various mathematical objects such "theories" (tweakable mathematical models) require …actually are?

What string theory does is....propose the graviton, the gravity as a particle, unifying the quantum with general relativity...but gravitons was not find yet

[@jerrdnn3373]

I can't help but think we are looking in the wrong place with the search for the graviton, yet I'm sure new physics will come of it. It just doesn't make sense to have a force carrier for spacetime, honestly it makes more sense that an absence of a force carrier would cause the effects we see in gravity classically speaking. We keep looking for what is, or what should be. But the universe is clever and lazy, I can imagine that what isn't there is just as revealing and important than what is. I wonder if the lack of the graviton is what actually leads to gravity, like the graviton cannot exist so it gives the illusion of a force or more precisely ; an anti force. It could also explain dark matter and dark energy, but I won't go into detail on how it could in these here comments sections lol.

[@danf7411]

Maybe gravity isn't a force and just the inherent properties of mass. Also I think gravity has a cut off point once you go under a certain mass it has no effect. You'd think we would of found some evidence to support this already

@@SpontaneityJD Fascinating. If light can be bent by gravity (and it is massless), then doesn't that imply that gravity somehow transcends mass as a "force"? What does it mean to bend light? If space is curved, what does that tell us about the statistical likelihood that space has a force carrying particle? I dunno. We will need another Einstein to figure it out and find the TOE.

[@ScribblerDeStebbing]

[@mykofreder1682]

Locally gravity causes space time to sag continuously, matter has been interacting with gravitational fluid for billions of years, and it works from atoms to super massive black holes. There is an exchange between matter and the gravitational fluid for billions of years and this is causing additive sag, there is no expansion just billions of years of sag. The real question is how is this energy taken is given back, does the limit on massless photons speed mean it is being dragged by the gravitational fluid and eventually gives it back?

I have a question as to why the potential is not considered in terms of Axioms that travel well above the speed of light and then lapse slow to such speeds as they become visible, losing energy until they form matter, thus filling in the voids. Just like experiments in Sophia, the plasma generated by the Cosmos operates in the Ether that allows for light, sound which travels faster, and all being subject to magnetic and electrical forces, but more than that which wii, the "I"s that form human consciousness, can detect and understand. While close, the only research on this is subject to the astral world or alternative realm that, makes all this exercise in futility. Without the keys to the door, wii seek to understand what is going on in the room wii can not enter to be sure that the view is not simply someone's Smartphone screen, not real at all. Once you experience remote viewing, seeing, feeling, and hearing as if you have a body but do not, then the entire concept of physicality comes into question. Since that ability has been proven possible, there is yet to be a scientific explanation unless holographic worlds allow us to slip between them without a time function and therefore, due to no matter, an entirely different set of rules for how that operates that wii can hope to understand from this side of the door of opportunity... kudos for asking the right questions to keep the Bakhtinian dialogism alive.
