I know Eric Weinstein has a big influence on string theory hate but Sean Carroll said, and I agree, that it doesn't cost much to study strings. Let them do it and let others study other things. Eric just has ptsd and to be frank, he's being a whiny (Weiny?) baby. Let it go bro. He works for a literal demon in Peter Thiel. I don't think I'll listen to Eric Weinstein on what's right and wrong.
This was really interesting.Listening to conversations where I get the impression that you don't hold back is of immense interest. As an amateur in the field I will certainly not grasp a number of things, but I think the level of the discussion encourages further study, which as far as I'm concerned is something very positive.
To help remember, I sometimes track backwards from the 'now' To visualise how to do this, I try to follow the reversed timeline of an ethereal thread of string with all its knots and nodules. I suppose following a trail of breadcrumbs would yield a similar outcome
Thank you very much Professor Keating! I'm always amazed that the conversations are even more inspiring every time. It's imho all top quality and your channel deserves a lot more attention!
When he says something's moving. How does he know that it's not time that's fluctuating rather than a fabric fluctuating? If time can bend, can it not also wave?
@@DrBrianKeating would you like to consider an idea to unify gravity. try find a reason to dismiss it. I haven't been able to. and it explains everything . supported by observation. if it's wrong it should be easy
The string is in 4 Dimensions, when 90909 / sqrt(22727 × 22726) = 4.00013200545625.. 1 inch ~ c^x/(G^y N^z) predicts String Theory. 9×3~ 2+7 so Pythagorean 9 squares the circle in 4D..
Not necessarily... _Type IIB String Theory_ is one of 5 flavours of _String Theory_ such as _E₈ x E₈ Heterotic_ and Witten thought that he needed to bring all these flavours together by thinking of them as a 11D multiverse rather than 5 10D universes each of which was a 6D _Calabi-Yau Manifold_ scrunched up at every infinitesimal point in 4D spacetime, however I think it curious that _Type IIB_ is unique in being the only flavour which has _S-duality_ with itself, all other flavours have this property with another flavour. So, I wonder whether this is a clue that these other four are purely mathematical and our physical universe is one of 10⁵⁰⁰ potential 'tuning' solutions of this _Type IIB_ flavour. It is also interesting that _Type IIB_ connects through the _Grand Unification of Mathematics_ which is the _Langlands Program_ and passes through _K-theory_ and _Modular Forms_ (used by Sir Andrew Wiles to prove _Fermat's Last Theorem_ ), into a connection with _Knot Theory_ which Witten has also done work on. Curiouser and curiouser. Then you realise that our Lorentzian X¹·³ pseudo Riemannian spacetime manifold has the only combination of temporal and spatial dimensions in which one can tie a persistent knot, as it isn't possible to tie a knot in 2D and knots in 4D can slip their bonds via an adjacent hyperspace and knots in multiple temporal and spatial dimensions can slip into an adjacent hyperspace where time's arrow is reversed by dint of that parallel universe having its Big Bang at the opposite end of our universe's lifespan so although it has increasing entropy within its realm that looks like decreasing entropy from the point of view of its parallel universe which would be the one we would inhabit. There is some work being done on models with two temporal dimensions, such as the work by physicist Itzhak Bars. However, having brought up these cases it should be intuitively obvious that (1, 3) is the only combination of temporal and spatial dimensions in which you can tie a persistent knot. Does this mean anything significant? Can a proof be created for this which explains why Protons are persistent within our universe as they are analogous to knots, but only when they are in (1, 3) 4D spacetime? This is an open question and does not preclude auxiliary dimensions that are compactified which usually involve imaginary numbers, so the extra 6D of the _Calabi-Yau_ manifold, or the additional imaginary dimensions of the PhD thesis of Cohl Furey, who has a thrilling series of short lectures. Her strategy involves using the normed division algebras to constrain extra imaginary dimensions in which she can build an analogue of the _Standard Model._ So this is ℝ ⊗ ℂ ⊗ ℍ ⊗ 𝕆 "behind the scenes" which when raised to the 4th power ends up scalar positive 1 rather than the square root of -1. There is also a paper online by 32D Trigintaduonions 𝕋 which is worth a read: Theory of Trigintaduonion Emanation and Origins of 𝛂 and π - by Stephen Winters-Hilt This ties into some of the work done by Max Tegmark on a mathematical universe, which is definitionally similar to Stephen Wolfram's work on a meta mathematical computational multiverse. I don't mind if the additional dimensions needed to accodomate a _Quantum Field Theory_ are imaginary any more than I baulk at physics embracing concepts like infinity.
its a piece of the pie that has been ate and there are no crumbs left. lets try another pie. at the least we can make string theory pie when it might be needed. but its not very filling. artificial physics is not a physics i can bang for.
String theory is a tool, its value is relative to its ability to help us understand the universe. It is still open for progress. I propose to not fixate on String Theory as being outdated or being the truth, (it is more likely to fall in between both) it’s a theory within many theories wich all can aid to our perspective in a relative unique way.
I'm going with Sabine Hossenfelder: "String theory may once have been a promising approach to a theory of everything. It no longer is." Contributions, yes. But it is a theory that is routinely in triage. Time to be merciful and send it to hospice.
Is the diameter of a black hole way bigger than the circumference? And if one was "inside" a black hole, would a "star" be smeared around the perimeter shining in rather than a star at the center shining out, such as in a solar system?
Strings 2023 was awesome! I can’t wait for Strings 2024! Although, I doubt it will top 2023. That one was particularly special, for several reasons- both intentional and coincidental.
Observation is the only explanation that's necessary, while experimental research is the core of physics 👍. Dr.Brian Keating is just the dude for the job. Peace ✌️
Right, the speed of light is not constant everywhere since the measures of time and distance are not constant everywhere. Only someone from the Amazon could explain this simple aspect of general relativity to you.
The real question is if string theory is real. "Science" is such a broad term. Let's narrow it down shall we? First off, it's called String THEORY. Not the the String MODEL. It's just a theory. That being said. Yes, it is "Science" in that it can be used as a tool to articulate for abstraction. But that doesn't make it real and you can't go around pushing it as a multidimensional theory if you ever want it to be "real".
If the universe is riven with rotating helical filaments that channel everything fermionic through them including galaxies and their central black holes towards/away from galactic clusters/nodes, might it be updated to a filamental theory of everything? Might a reexamination of universal free fall, momentum and inertia then be undertaken at the constant speed of massless bosonic light by us hominid observers? Could expand on the universal aspects of this massless acceleration radiation idea, bad pun intended, but will sit & ruminate on it for now! Another brilliant science discussion, thank you both, as it's a much better leisure time hour spent than watching the daily news!
@@youtubesucks1885 Which is a strong indication of the incompleteness of those theories. Neither are wrong, but both are incomplete. According to experiment, the 3+1 spacetime dimensions of our observable Universe are indeed invariant.
@@psi.squared9448what is that comment supposed to mean? Scientists that have scientific theories shouldn't be on a science channel talking about science because they might be of a specific religion? So "International politics" colours your opinion of scientists on a science channel talking science? What is wrong with people?
I think of them not as strings a but as cords where the universe rings at frequencies and structure is formed by the interactions of the wave states, sort of how a Bose-Einstein condensate if formed from bosons.
Brian this may be one of your best oarated pods .great guest and great questioning both of you nailed it ! Our relationships with tools and modeling are clearly problematic. Because of this i support exploring all tools and models to one day have time and place applications but we dont have to accept it as ultimate reality. I'm very confident that one day we will have several unified theories that are in different language models and levels of knowing. This doesn't mean usa tax payers should fund every idea liks string Theory this must be a private study . We need ways to remind ourselves in the etymology,. The grand unified big bang evolutionary universe and here we are then end story isnt allowed to be wrong or prove to us its wrong. Everytime evidence tells us in biology that evolution is wrong and isn't woven into the fabric we simply engulf what we learn into it and pretend it wasn't contradictory and then teach the next generation it was always that way . Weve acted like the The Greeks as if we have the finally answer but just need to fill in the blanks and find the missing links which denied the Greeks from inventing the steam engine despite having all the knowledge that was needed.

This was always a dumb theory. Honestly it's time to kick the math geeks out of theoretical physics. Their idea that anything they can calculate for mathematically MUST be possible? It's ruined the field. String theory, multiverse..it's all a bunch of nonsense.
Yes, but.....your idealism blinds you to the actual goal of all of it - to keep the grants flowing and the cushy mathematical fantasy going. At its heart, nearly all of what is currently called theoretical physics is a simple grift.
"Being able to and interesting" is as low a bar for pursuit of a subject as you get in science. It is a complete lack of standards which easily leads to pseudoscience or non-essential philosophy.
5 dimensions aren't enough for the behavior of relativistic superstrings to match the particles and forces of the standard model; but when you add more dimensions, they do. I think that's as far as the proof would go. It's still within the theory, not saying anything outside of it. * The "super" in superstrings just means asymmetric chirality, like the string was made out of linked > shapes: >>>>>; otherwise they're just strings like we normally think about them except very strong & moving at relativistic speeds.
Of course String Theory it is not science. Real question is: who or what pushed this unholy complex brain fog on academia. Penrose' twistors are far more interesting for anyone who is into geometric wrapping of continuous fieldlines into quanta of local windings and related longitudinal orthogonal contractions. This concept is much more intelligent than vibrating loose hovering strings so small you can never see them (duuhh), and which concept would never allow for symmetry and zero some dual motion. Who ever pushed this, knows how to appeal to the egos of our leading physicians. They just can't resit the lure of diving into incredible complexity as to distinguish themselves from the ordinary. But the irony is that we can't reach for the stars and go beyond Einstein unless we revisit the childishly simple fundament of Einstein Special Relativity. More specific; the missing equivalence relations. Deliberately or not; Einstein sabotaged physics by separating mass & energy on one side and space & time on the other. He lied. The only one who seems to get it, is Sir Roger Penrose. He says Mass is fundamentally equivalent to inverse time (substituting E=hf into E=MC2) and as a result so is Energy equivalent to inverse space. Hello? Is anybody listening? With this, Penrose attacks the alfa an omega of 100 year of Einsteinian physics. If Roger is correct (spoiler alert: he is) we need to go back to SR and finish the correct fundament of physics. It is literally child's play from there...
Twistors sort of a math analog to rotating helical universal filaments? Even the helical RNA/DNA "unconscious robots" get their upward climbing crooked ladders together to line up & pull-apart their cellular filaments to create scientific observation as we type?
@@dansbike1 I see. So we're invoking 'Dark Experiments" and pretending they've been successful? When do we get to invoke dark variables to 'disprove' something so we can redirect funding to something more useful?
You really need religion not to work one day a week? And what’s the point of stating that historic scientists were religious? Back then everyone was or had to pretend they were and we knew only a fraction of what we know today. Also, the usefulness of religion has no bearing on whether it’s true or not. As a scientist or any logical person, it’s best to only believe in things for which there is good evidence.
More conjecture, yet no evidence, instead we get checking a theory with another theory. Must make for interesting games for string theorists to play, it is, supporting conjecture with more conjecture.
hey doc! greetings and solace. Looking forward with optimism to the Evidence that Lost souls have challenged Humanity to find. Theories and Accounts have to merge one day, even if it isn't this day because One day is actually every day. Anyways im a little crazy for the best philosophies. Dr. B K your a catalyst in physicsy thingys. Preciate Prosperities. jajajaj
I am by no means a expert on this. But if im not sure anyone can be an expert on a “theory” that can’t be tested or proven. How can science have been so single minded to waste most of the great physicists of a generation on one hypothesis
When does Einstein come into the picture? Once he shows up when does he reappear he is not there through the process. Einstein jumps in and out, that one is for free lol.
try challenge this idea. @t = c / us where @t is time dialation c is the speed of light in a vacume us is undiluted space it calculates the rate of time within mass like glass and lead. a black hole. or in space without mass that would have the observed effect of dark matter. if you cant find a observable contradiction. ask me how it unifies gravity.
One may not judge a book by it's cover, however, judging humans by there countenance is another matter for those whom go by instinct. EG: the countenance of Mussolini and Trump. Countenance says it all when it comes down to looks. Likewise my acceptance of baby boomers physics. One can judge the struggle to the top in the wake of waves of vibration in the game spread over superposition of the discrete structure we see. Universities the place where alchemist like Leonardo and Newton are turned into the reformation according to Henry and the Popes'. Long live tax havens and the reality of one god and their universities.
Math is the Supersymmetry. Formulae (No matter the size) equals result. I am done with that. Human interaction is not like that. Observation and desire to prove the relation to already known/experienced things builds up the frame of our Knowledge. But the "competition" among Diploma- and prize hunters is fracturing something, that should be united. We all observe the same Universe after all.
😊we are entanglement in the strings of the universe itself is a long-term relationship with the States of vibrational currents that convergence is the best idea for the layman terms of life and what we will see in every aspect that strings of vibrational currents that stir the mindfulness of creations own making a decision about itself is listening to every single song we sing in our own way we biological beings are the strings that play together with about everything that is around us and how we have been able to manifest our current lives War is a very badly thought of the world but yet there is still idiot's that worship it's not the answer to problems with the world it's intentions of politics that started the stupidity of war's and struggling to controlling their ideals so cut it off at the knees and pray for a continental entanglement of truths about what's going on in it.we are a Quantum of energy and environmental entanglement in everything that is a string of actionable vibration ❤love honor each other and respect the nation's greatest in life is the most important thing's not money not powerful people noticed that nothing is permanent and that willingness to help each other as one person has to be the threaded of our world and nothing more nothing less
