Is string theory a failing model? | Eric Weinstein and Brian Greene go head to head again

- Eric Weinstein clashes with Brian Greene over string theory's place in physics.
Weinstein is notorious for his stance against the string theory community's toxic culture, previously telling co-founder Michio Kaku he is "out of control". In this tiff with string theorist Brian Greene, Weinstein once again confronts both the culture around string theory and the validity of the model itself.
Watch the full debate at iai.tv/video/the-trouble-with...
String theory has been dominant in theoretical physics for thirty years, with more scientific papers arising from it than any other theory. But critics argue the theory has held undue influence and it is an error to pursue it.
Is it time to move on from string theory, recognise that the search for supersymmetry has failed, and seek alternative accounts of the universe that are supported by observation and experiment? Or is the continued dominance of string theory justified by its potential to unify our understanding of the universe once and for all?

At least they swapped out angels for dimensions on the head of a pin.
Logic determines that the absolute state is impossible and that change is necessary. A string taken to be a purely abstract, dynamic relative magnitude would seem plausible. Patterns emerge in higher dimensions from one dimension.
Generalisation of what is known would seem to be the way to proceed.
Walling off science behind a paywall is problematic...
Unbelievable!
@@ObiAdeGaming I don't mind a paywall in general when companies are up front about it.

@@sighfly2928ok I’ll trust you
😂
I wish I was smart enough to have an opinion on this
ha! same - to me they all seem way beyond anything I could ever understand
I wish other commentators realized this...
Basically the debate boils down to this.
Scientific theories have two functions: explaining the data we have and making new predictions (that if successful should be correct).
One would expect that using the scientific method that this would eventually lead to a fundamental theory about how the universe works, but for some reason it is instead that we have two inherently different and incompatible theories: one for small objects and one for big objects.
This feels and is considered uncontroversially wrong. Like for example when is something considered "large" and what happens if you have an object that grows from "small" to "large" does the laws for that object just suddenly change?
The only thing we have is string theory which explains some of the data and makes no predictions. Always in the past when we have a successful scientific theory it explains all the data and makes a bunch of new correct predictions.
So basically those for String theory argue that we haven't had any other theory explaining the data for 100 years so it is worth researching this.
And those against it argue that it isn't worth it because it doesn't follow the traits all other successful theories have had.
@@gogl0l386 Well, no. LQG for instance doesn’t even give GR in the semiclassical limit due to Sen’s work. Strings are worth it because of AdS/CFT, and recently a part of a collaboration I’m a part of showed an approach to dS/CFT, which is a stringy notion of our own universe. Hadronic physics has had some nice things, except SUSY, which in its own right explains a lot of the early universe we can physically attribute to. So string theory being “bad” isn’t true at all - only that SUSY hasn’t been found yet, but strings are elegant both mathematically as well as observationally. I am a physicist myself.
@@Daniel-ih4zh Exactly. I’m a physicist and I am absolutely baffled by people who watch a few videos claiming strings sucks
The problem is that they use the phrase "The problem is.." so much that nobody knows anymore what the problem is.
The problem is, "the problem is".
Theres just alot of problems apparently.
99.. to be exact.
The issue here is string theory has never really been a theory supported by evidence. It is a hypothesis with internally consistent math. The math may be elegant, but if it doesn't make predictions that can be tested, then it isn't a scientific theory.
A solution looking for a problem that doesn’t exist. Indeed. To be fair in such criticism, we can say that about many “theories” out there.

anyone else here just thinking, I want to hug Roger Penrose. He reminds me of my grandfather at every family get together. Has lived through life, been through this so many times, he's just enjoying being around the next generation that is starting to do the same. This video gets a like - thanks so much for keeping the conversation going!
My grandfather was a creep, so no.
I actually experienced this situation while graduating in mathematical physics in Belgium. It was the year 1986 and I wanted to continue the studies towards a PhD. In the dept. there where many groups, but the strongest was string theorists. Proud of their 100s pages calculus which not many understood. I was discouraged to continue physics as it seemed to me so far away from it and I was not so keen in pure math after all. On top of that, no jobs in view...
Someone said (I believe, they even have researched this), that a wrong scientific theory only dies out, when the generation of scientists adhering to it also have died out because of high age.
Most people, including scientists, will never admit, that they wasted their whole live on a wrong idea.
Nothing like a wall of mathematics to hide a suspect theory. Perfect camouflage.
Well, no matter which way you cut it, modern physics is extremely mathematical. The math in string theory is the same math in general relativity, were you planning on skipping that, too? I'm just saying: being a physicist means being good at abstract math.
@@geometerfpv2804 Physics is about observing nature and derive the predictive best models from these observations, math or not. Observations changes all the time, so does our models. Maths are one tool (powerful I agree) but not the only one.The rest is intellectual games, or informed intuitions at best, and you might hit a gold stone or not.
@@tixch2000 Pretty much every reputable modern theory relies on a rigorous mathematical model to be able to predict anything with any degree of accuracy, the complexity of which depends on how fundamental the physics are. You can't get away from math if you want to do most, if not all, forms of physics.

What Sabine Hossenfelder has said particularly stands out: that the test of a theory is whether one gets more out of it than one puts into it. General relativity easily passes this test, as does the basic quantum mechanics established in the early 20th Century. Other theories, such as QED, are less clear cut. String theory seems a distance away from achieving this milestone.
That's following Imre Lakatos' idea of a research programme. The programme develops and tests a body of theories, then as long as there are worthwhile tests to carry out ("producing empirical content or novel facts" as Lakatos put it), then the programme is just happily marching along. However, eventually it is exhausted and then either put on a pause or abandoned altogether.
The problem is that many scientists are not aware of how the Lakatos framework is supposed to work and instead rely on Popper's notion of naive falsification. As long as they are "not proven wrong" they believe they ought to continue their work, when the real question they should be asking is "Is all this worth my time and efforts?".
Sabine Rocks!
Sabine Hossenfelder also helpfully explains that for fusion technology one must also get more energy out than one initially puts into it, this then suggests that string theory may be a multiverse analogue of fusion power - two universes of intellectual endeavor that as applications of time, intellect, capital and effort soak those resources from every other parallel activity to no discernable positive effect. Will those black holes ever evaporate?

Einstein was a genius when he came up with general relativity. And he was a stubborn idiot, when he kept denying Quantum Mechanics.
In the very same sense Tesla was a genius when he developed his induction motor. And he was a complete moron, when he fought against relativity, the emerging atomic model or, as I said, when he tried to come up with his wireless electricity grid.
No. This doesn’t apply to theoretical physics. As a physicist there is nothing worse than a bunch of people arguing what we are working on is wrong or useless without understanding so much as a single equation or a single paper.
Regardless of it's untestability, as long as people can pay their mortgages promoting String Theory, it will be something we have to hear about.
thank you
String theory doesn't make money, and it's not expensive to research. It's the most important theory physics has ever developed, it produced more insight into quantum gravity than anything that came before. The claims of people like Weinberg are pure fraud.
+1000 Internet Points for the "Eek-A-Mouse" reference! Also, correct on shilling this Snake Oil. As long as it sells, it will be sold.
Space-time was un-testable too, until we got computers, and colliders and laser interferometers decades later. Same with atomic theory, chemistry, hell even machine learning was developed decades before we had multi-core CPUs never mind tensor core GPUs, FPGAs and TPUs.
Point being: science is science until it is ruled out, not because of how we feel about it or until we get bored of trying to understand it.
The biggest problem with populatizing theoretical physics as I see it (albeit the lesser evil) is conflating the every day world of "preference is MY truth and that's just as valid as objective observation" with science, which by definition aims to be impartial and strictly objective lest it be considered invalid unilaterally by default.
I remember a physics postgrad about 20 years ago complaining that if the research proposal didn't include the words "string theory" then funding would not be forthcoming.
The theory has consumed vast quantities of clever people's time, and delivered nothing remotely useful. And worse, has displaced other work to such an extent that Physics generally seems to have delivered nothing of much value in the last 30 years.
Its anti physics yes. A vacuous vampire. Perhaps in a round about way it has discovered anti-gravity by putting a mental void in so many peoples mind.

This is a particular example of a general, society wide problem. There are many disciplines where an elite has walled themselves off, creating only self-referential assertions.

Lack of bandwidth is the plague we all suffer too , constantly maxed out attention and a shriveling concentration span on top !
it's so over ... it's never been more over
It's not as self-referential as it might seem to you. There is a valid criticism here, but the scientific community has also been incredibly successful at actually making things work. So...I think it's a case of "this is the best system we have". Brian is right, you literally can't consider every theory. He wasn't exaggerating when he said it could take a month to understand someone's theory, and 99% of the time, you're wasting that time just to show that they were wrong in the end.
That's why we focused on "credentialed" people. There needs to be some system to filter out all the stuff that would waste enormous amounts of time. This DOES lead to elitism and nepotism, yes, but what is the alternative? I don't think lay people really can understand what a massive investment it is to read a theory, even when you are an expert. This is a thing that takes hundreds and hundreds of hours to do. So, you have to be very careful about how you apply that time. Given that, are you going to read the next theory from the MIT guy famous for making good ones, or are you going to Eric Weinstein's "academia rejects my theory, but I'm telling you, it's correct!" theory. Keep in mind, it's a job. You have to publish accepted work to get hired and promoted, so it's not like you can afford a charity case. You'd probably do what we all do: read the person with credentials, because they are *likely* (not certain to) have something worth the time.
@geometerfpv2804 that's not how science works at all. You don't have to have a PhD to be correct.

Yep. I noticed. I guess he has finally realized what he got himself into. One would think that scientists at his level would have assistants that would warn about and prevent these situations from happening in the first place.

@@gregorys5329 ah shoot, you're absolutely correct. I was mixing up my famous physicists. I'll retract my other comment
He perked up a bit because Weinstein is echoing a sentiment that he also holds. That being that forcing quantum rules on gravity is only part of the picture, if any at all. The quantum theories we have also need to be "gravitized". The tempting assumption is that, since QM deals with the smallest phenomena in the universe, then gravity must be an emergent phenomenon that arises out of that. But it may well be the case that the spacetime curvature depicted in GR may be a fundamental aspect of spacetime at the quantum level, and thus has to be treated with modified GR rules.

You're spot on! And Brian Greene is really the wrong person to address all this to.
Maybe he’s waiting for proofs of the criticisms? Although, I concede, that goes both ways..
Eric is always chasing the car, but doesn't have the interpersonal skills to collaborate
Eric literally admits he might be wrong…and has done so on numerous occasions. No string theorist has ever said that
Cutting edge scientific conversations behind a paywall, i dont know how i feel about that
When I worked with Brian Greene on The Elegant Universe, I specifically and explicitly tried to help shape a book that was antithetical to Kaku's overstated approach: i.e., to stress that this first book of Brian's, at least, would emphasize the process of trying to discover a 'theory of everything' rather than ever explicitly state that strings/superstrings/M-theory was the likely solution to the underlying problems in physics. --Vid Hardt aka David Steinhardt

I have no degree but I read a lot and I was amused when I read a mention of the constructor theory . The theory as it was described defined the meaning of the theory as simple:: Anything that seems impossible becomes possible when new information is found. I looked for the definition of a word in the theory : "
ergodic › Wikipedia
Ergodic theory is a branch of mathematics that studies statistical properties of deterministic dynamical systems; it is the study of ergodicity. In this context, "statistical properties" refers to properties which are expressed through the behavior of time averages of various functions along trajectories of dynamical systems. The notion of deterministic dynamical systems assumes that the equations determining the dynamics do not contain any random perturbations, noise, etc. Thus, the statistics with which we are concerned are properties of the dynamics.
Ergodic theory, like probability theory, is based on general notions of measure theory. Its initial development was motivated by problems of statistical physics."
Well isn't the word impossible to apply any meaning to because statistics are never exact. Its a word that I HATE passionately, for some reason I've never understood. I have hated the way statistics are gathered and used in science as truth . mathematics can't be generalized, infinity can't be specific, not ever.

Arm chair scientist here 🤚🏻 , Is it possible string theory is just missing an input? One from assuming space is a void for an example? If everything is connected, and everything is in motion , then maybe there is a medium that everything is in. The medium is interacting directly with matter, in waves. These waves are the resonance that give matter its ability to take shape. Like two waves crashing. The exact place we get our geometry from. Then every piece has a specific frequency it resonates at. Which would mean everything is something because its vibrating at a certain frequency. Like sand on a table instantly changing patterns to different frequencies. Or how they killed leukemia cells by hitting it with a certain frequency causing the replicated cells to shatter , and the original cell to swell and die. these past couple years with what they are finding about biology, and things being done with frequency i think there is a strong standing point on this being what gets us to the next level. Maybe consciousness is collective, and we are all on this ride together connected. Hurdling through this river of force of electricity and magnetism , and the introduction of vibration is what set everything off. Something like that 🤷🏻♂️

This kind of content should be free to watch. Not charge people to see the full debate.
8:00 this is where peer review comes in to play, if u are a mathematician, and ur friends with a physicist, communicate with each other and recommend certain new theories, and use the typical book hunt approach, I don’t read the whole book and try to expand if it rings true, I read the back cover, or I take a recommendation from a similar minded individual, appears communication has always been a weak point of the leaders in these fields , but it has gotten exponentially worse recently. And in the people who communicate well their basic understanding of math and science has plummeted as well, we all focus far too narrowly and limit our friend groups in and out the lab/office and mostly don’t socialize at all
When looking for competent explanations of things, never ask Eric Weinstein.
Hold on, let me give you a 50 minute explanation to a 5 minute problem.
How else will he be able to editorialize and overdramatize things in order to tell you how to think?
Please put full video on RUclips as there’s no captions on your website and I have hearing problems
please, just put the whole thing up on youtube.
The beauty of this is that this is Science. Not everyone agrees and we need this.
My feeling is whether String Theory ultimately ends up being correct or incorrect is irrelevant, we should continue working on it if for no other reason than to eliminate it as one of the many possibilities that exist, if in fact it isn't correct. We learn more from our failures than our successes.
I agree, but the issue is that the manpower/brainpower funding that it takes away from other possibly viable theories. I think that's the point of contention.
Totally agree, I hadn't thought about it in this way and you are certainly right.
That is moronic
Eggs...actly
How do you eliminate a theory when those who cling to it continually move the goal posts?
I think BG summed it up perfectly. People are literally talking past one another because who has the capacity to truly understand _two_ massively complex theories? In my former field, CS, we argue about programming languages. Same thing: Nobody is really a master of two competing programming paradigms, thus, no one person can really objectively decide which is truly better.
Computer languages aren't inherently better than one another. They have different uses. I wouldn't javascript to write an efficient large language model just as I wouldn't use geometry to give me the probability of two events happening. String Theory may possibly be totally inherently wrong and completely useless just as the theory of flat earth. To say you don't have time to look into multiple theories is ridiculous given that Eric has done just that.
@@FerrisMcLauren If Eric W has turly dived the depths of Edward Witten's analyses, then Eric W wins. However, I don't think he has. Otherwise, he would have attacked ST at the technical level more precisely. ST is wholly derived from math, and math has always been the workhorse of physics. I don't follow the arguments of these people who now want to throw shade on math as a "pointless pursuit of elegance." Show me exactly where Witten's math diverges from solid physics and I'll shut up. Witten took the ball Feynman carried and took it much farther. Apparently too far without PR backup. Both Einstein and Feynman had excellent PR, but not Witten. Alas for the human factor.
@@FerrisMcLauren A language can definitely be better than another. Usually two good languages are different and complex enough that whether one is superior in a certain circumstance is difficult to ascertain, at least initially, but some languages are just worse than others.
Nobody wants to build apps in VBScript, for instance. Many liked VB6, which it was derived from, but VBScript is neutered by only being executable from Microsoft 365/Office filetypes. VBScript supports 64-bit compilation whereas VB6 doesn't, but that's a feature of its proprietary 1st-party compiler rather than the language.
@@vonBottorff I may be too dumb for this. I just get SH's point.
First of all, it should be about who makes measurable predictions while explaining known measurements.
Then it should be about how many (or few) ad hoc parameters you put in to get how many predictions out. Fewer wins.
On both counts I don't see either doing well. So to me, the debate is basically between two men arguing about the number of angels dancing on a needle.
@@vonBottorff God you people are so wrong and off its sad. "Math the work horse of physics" is probably the most foolish statement and sentiment of the century.
Its so funny because Tesla could tell you what a electromagnetic field IS and the "math is the workhorse" guys can only ever tell you what it isn't aka quantized vs qualitative.
Feynman was an absolute moron the dude could not explain how a magnet works or what an EM field IS, he could only describe it in terms of quantity and or area of effect.
We are being led by the biggest morons on earth they're worse than ignorant or those lacking in knowledge they've created dumb junk nonsense knowledge which covers their ability to see like a blanket of stupidity.
This was a great debate. I wish I understood it.
Never mistake another person’s jargon with their intelligence
As I have said before, Eric Weinstein can take a simple concept of physics and make it incomprehensible in five minutes or less. Although it usually takes him 20 minutes.😊
Totally - I remember at one point on another stream he had me thinking I didn't understand what a fiber bundle was but then I went back and looked it up and, nah, it was exactly what I originally thought it was - It's the opposite of science communication.
He is just saying that there is a clear tribalistic bias, almost religious in the physics comunity. Either youre part of the "cool guys" with the string theory that happens to not have give it ANY real use to society bc after 70 years the theory is not complete or either youre part of the "dumb guys" wich is basically every other physician.
In result, hundreds and hundreds of really intelligent people carrers are being throw in a volcano bc the string community is so proudly blind that they cannot NEVER admit that maybe the string theory is just a whole missconception.
Just word salad to look smart
Weinstein is incredibly pompous
it's almost like the cart is before the horse. String theory grandiosely presupposes the fundamental structure of things and hopes some magical constraints emerge down the line, whereas SR elaborates reality from the notion of invariance of C, GR the equivalence of acceleration and gravity, QM uncertainty principle and then constrains the underlying fabric of things. As classes of thought with respect to adducing the nature of things string theory seems to disconnect itself from deep intuitively compelling motivating principles which have previously created parsimony....
BG is a genius and I respect him and his work.
But his opening statement is a doozy.
If you spend most of your time on X, then you should see multiple ideas about X.
Its like trying to defend people that worked on how many angels can fit on the head of a pin because they improved book binding technique to capture all that nonsense.
Why should anyone care that the smartest people were bullies when considering the validity of their propositions? So what if they looked down on you and called you stupid…either they’re on to something or they’re not. And so what if they’re not reading your work. It either stands on its own merit or it doesn’t and everyone involved is free to pursue whatever avenue of investigation they want to. This all just seems like whining to me.
So, this is basically Eric Weinstein holding grudges.
Because he wants to grift his nonsense and won't release a peer reviewed paper.
He just wants everyone to accept his grand verbose adjective rich explanations of things that explain no overall prong of a test for anything let alone his own theories he has barely released or been willing to publicly debate/discussion.
I'm not even a physicist and I can regurgitate arguments against string theory.
Why is he even included here lol.
@@JrobAlmighty That’s the thing. I am a physicist, and I get asked if strings are right. I can bet my money they are, because it works. Half the public comments that string theory is bad even though they don’t know the first thing about physics.
@@vaibhavk2400 correct, after taking courses on string theory, I realized why string theorists don't want to debate people. People are clueless about string theory but will still hold opinions on the subject.
@@JrobAlmighty Peer review, if you've paid attention, is not what it is cracked up to be. Much of science has taken on a religious like dogma - much of which seems evident on the reverence for String Theory.
My energy dog ate my energy homework lol
Link is broken ????
My favorite physicist just listening to these people arguing on string theory. Isn't it lovely
I need to know Granpa Roger's thoughts during this
Can we talk about the fact that the Nobel Prize winner is doing the least amount of talking?
We needed eric crying for 29 minutes complaining about not being respected for being a crank
Eric Weinstein sounds extremely frustrated that his attacks get ignored. He's been trying to convince us that his frustration is important.
We're not buying it, Eric. If a theory can't yet show empirical data, it says nothing about its validity. Many prior ideas in physics couldn't be experimentally demonstrated - for years. String theory explains a large group of conundrums in physics that nothing else explains. It shouldn't be discarded simply based on frustrations (and unreasonable expectations that it hasn't progressed "fast enough").
The paywall for the full debate blows. But after listening to the first 5 minutes I was debating if I could handle any more of that baroque background music anyway.
This needs an Epic Rap Battle.
How does Eric get on these panels? Ugh.
That's show business.
Because he dominated this discussion on merit.
@@audiodead7302 Bingo... He brings the clicks. Even I am guilty of watching him "tap dance" out of a kind of morbid fascination. He's a Gish-gabbler genius and petty and defensive and consistently makes personal attacks (he almost always accuses anyone who disagrees with him of stigmatizing him and he imagines there's a kind of status quo institutional mindset that is "threatened by his work" and somehow keep his theories from being accepted or understood).
Whatever... obviously, this guy stick in my craw (I should be grateful he motivates me to keep up my meditation practice!), but you're right, guys like that bring in audience.
And the full debate video is behind a pay-wall?
As a non-scientist, I remember Michio Kaku in the 1980's going on his radio show week after week evangelizing string theory, and doomsaying the dangers of nuclear power. Now two generations have passed, and string theory appears to have bogged down in a predictable tar pit and people are awakening to the idea that nuclear power is the best option for safe carbon-free power.
What I learnt from this debate is the quiet host (I guess that’s who she is) is hot!
Another concern is that string theory might prove to be true, but we might have missed a good theory somewhere in-between the current testable theory’s of quantum mechanics and relativity and the currently untestable string theory. At least with todays experiments. We could be missing out on a lot of technological advancement. Chemistry and Newtonian physics are good approximations of the universe but relativity and quantum mechanics were needed for nuclear bombs and gravitational lensing telescopes. I would be happy with some kind of quirky theory that combines relativity and quantum mechanics but requires a bunch of charts of constants you have to interpret from. I guess I would like to see some kind of faster than light travel be either invented or proven to be false with a much greater certainty than today.
What?? How is chemistry a "good approximation" of the universe when all that theoretical chemists work on is quantum mechanics? The rest of the chemistry field doesn't even attempt to "approximate" the universe, so what are you even on about???????
String theory isn't to be taken seriously at this moment. It is more of a sepculative theory, or rather a hypothesis. It can be interesting intellectually, but nothing more.
More fields, more professors, more money.
So it's just a small clip and essentially an advert for your site.
wow
Eric always looks so immature in these debates.."no one's listens to my theory" 😭
I don't think he was immature, rather I think he feels jaded and slighted but for good reason. I believe he was respectful. Also he does have a point about listening to his theory because the people in string theory that control science community will often say "let's see your theory".
@@LeeLee-kk1quthere are those willing to listen to and discuss his theory though. Yet he seems to prefer acting like a victim instead of engaging with his critics honestly and constructively to try to spread his theory.
It feels like a lot of this is skirting around and sometimes dipping into the question of the ethics and/or politics of science and the applications of it in the post-academic realms of activity. The A-bomb exploded this terrain open and now it seems largely forgotten that there should be serious social discussion on the merits of how much funding and attention certain théories or programmes of research receive. Or at least of the kind of attention.
👏👏👏
String theory is not a theory of quantum gravity, nor has it ever claimed to be! The background continuous spacetime is never quantized and is there from the beginning. It is simply the physics of 1d objects rather than point particles. The fact that gravitons (spin 2 symmetric massless particles) come out of the closed string spectrum for free is serendipitous. No other theory is even close to that! That’s why it currently remains the “only game in town”
Brain at this point is basically a religious leader, and his religion is string theory. Without any evidence, not even as much as the tiniest hint of anything that would even remotely imply that any aspect of string theory makes sense, he still keeps pushing it forward. I mean, I understand, he'd lose a lot of funding and his career would basically be over, and his life wasted, if he admitted that string theory is a failure.
Just string theory’s contributions to pure mathematics make it not a waste. If string theory turns out to be wrong, his life is as much of a waste as literally anyone else’s.
I find the most frustrating thing is being taught that in science theory does not preclude to an idea as in other fields of inquiry.
Theory is above laws, principle and facts. Theory of relativity, theory of evolution… but then we get string theory… then we get physicists saying I don’t have time to go through every “theory”.
🤷🏼♂️
The graviton is not a commodifiable thing. Once it is discovered, it will also be discovered that for those that doubted it's existence, that they should stay far away from it because it implies delving into bottomless depths of power, for which humanity as a whole is simply not ready to reap and turn... into a commodity.
Eric Weinstein complains that physicists such as Greene don’t listen to his takes but when Tim Nguyen did a deep dive on Weinstein’s GU “theory” in good faith, finding numerous fatal flaws, Weinstein went after Nguyen and his collaborator (who used a pseudonym because he was afraid of potential adverse consequences for his career, something Weinstein of all people should be respectful of). The attacks on Nguyen were so irrational and his failure to engage was so cowardly that it’s bizarre people keep inviting him to do these kinds of talks. Were Peter Woit or Lee Smolin not available?
What a great discussion/debate. I like how all of the guests can agree and disagree on things without letting their emotions take over
I have no idea why I watched this. Basically nothing they talked about was anything I knew enough about to follow.
Why Michio kaku missing from the conversation?
Because He and Eric would've been throwing hands at each other
He's out of control
I'm not afraid of being wrong, I'm afraid of repeating that wrong on a consistent basis. My parents called that acting foolish.
It seems like our notion of what a “community “ is has become extremely shallow.
It's held together with...string. XD
This reminded me of Plato's "allegory of the cave", you can't see anything as long as you stay inside the cave, but it's also comfortable to stay in the familiarity of the cave, at the same time that comfort reduces the desire to go out and explore, therfore hindering potential for development.
Weinstein complains that he spent the time to learn about string theory while string theorists can’t be bothered to learn about his pet theories. The problem with that complaint is that no one forced him to learn about string theory-it was his choice.
