I like to think that he carry’s that piece of rubber everywhere and has it ready for this specific question
😂😂😂
They bring on props for the interview
@@jonahshapiro2707 congratulations, you killed the joke
@@vaeppur(つ'°ᗝ°`)つ
He does
I'm really sure he can explain quantum physics to a 5yo
No one really understands quantum physics
Yep
There's a book called Quantum physics for babies. It helps kids understand it. That's how I understood. 😂😅
Plot twist thats the most complex description that he has.(of course not)
@@spohg2887nobody really understands anything
I was once in a small fender bender on the interstate - no one was seriously injured.
Michio Kaku was the first person on the scene and made sure everyone understood the basics of quantum mechanics before leaving and letting the first-responders load us into ambulances
underrated comment tbh
Hero.
😂
Amazing!
🤥
This man is so cool. I appreciate science communicators who don’t sound or act condescending while explaining.
Absolutely agree, there are a lot that sound too full of themselves
This video (the original one, not this short) was the first time i actually understood the theory after trying to do so for about 4 months. After that he immediately became one of my favorite physics teacher
He seems so willing to teach as well
Too bad its wrong😂
@@Ripen3what you mean? How's it wrong?
@@rainmanj9978it’s not even wrong 😂
it means it's not a theory
just a framework@@rainmanj9978
They say the deepest understanding is portrayed through the least amount of words!
That's valid. Another saying I like is "If you can't explain a complex concept to your grandmother, you don't understand it well enough."
Occam's Razor, though I'm probably spelling it incorrectly. It's a beautiful explanation of simplicity usually being accurate and very worth a Google💖
@@ProtusMoseRead the same thing but it's 5 years old and not grandma.
This is what stupid people say to cope with not wanting to put in the effort to actually learn anything
You are spot on.
All fine and dandy until the question of "What are the strings made of?" is brought up 😅
Exactly. Theories upon theories are in the end still not facts
@@9196dreamers They can be in science
They're made of nothing, they're pure Energy
It's wave 👋🏿
@@9196dreamerstheories are attestable facts... What's not proven is called a hypothesis... Unless you can prove a hypothesis it's not a theory... So take these theories as facts as they are the truest representation of our understanding of things as humans... Unless you are a believer and will believe in anything that's written in some weird holy book and run with it without the pursuit of the real truth
Reminds of Feynman's challenge. This explanation was beautiful and elegant in its simplicity.
I was thinking the same thing!
Is that the Higgs Champaign bottle winning cocktail party analogy?
During my school days, I once saw Michio Kaku's narration on Discovery Science that I started watching that channel and got into Science.
*But after watched video clips Kaku discussing with Prof Roger Penrose about 26 dimensions in String Theory, many people thought String Theory is just scientific fiction. 😅*
@@JackReacher110 because it is a fiction, @erastrotalked about it a year ago in her yt video.
@@ModernStupidity-qm3rjI see your nick.
hes good for sparking interest in science, but as the saying goes "Science doesnt say anything,Scientist does." So he can be biased also not to blame him.
Same bro
This man is a legend!!!!!!
Nope, he really exists. You've just seen him
@@robert48719hmmmm idk he could be a hologram
@@robert48719You’re English skills aren’t the strongest, huh?
No worries, honestly only looking at your writing it seems quite good.
I recommend looking up “Hyperbole” it’s extremely common for native English speakers to use this.
It’s a little tricky getting used to it, if you didn’t grow up with it, but you got this!
Another example would be:
Someone saying: “I feel 1,000,000 times better!” They don’t literally mean that they’re feeling a million times better, but that they’re feeling incredibly well.
Of corruption butt a legend for ignorant daydreamers.
watch angela collier about string theory and him.
I just love listening to him. What talent and skill he has to break it down so that I can understand. Such a brilliant man. Utmost respect to Dr. Kaku
being able to simplify any explanation for any level is a sign of deep and true understanding
I love Michio Kaku and his passion for string theory. Its unfortunate theres zero evidence to support it.
I don’t need evidence! I support his passion for String Theory unconditionally :^)
Hence the term "theory."
@@Lynn7015hb please explain.
@@Lynn7015hbtheories aren't like you think they are. In science, something needs to go through a lot of experiments to get enough information and proof to consider that maybe it's true, and then, it becomes a theory. There are a lot of examples of theories in the past that at the time, people though that were real (like how the evolution in the animals worked or how actually a cell looked like, for example), but whit the technological advances, those theories changed.
Sorry if you don't understand because English isn't my first language, but y hope you get the idea ;).
@@qwut9544i support his passion, just not string theory
String theory was strong in the 90s and 00s but now just fade away into oblivion
How would you know that
@@josefdrapak1889It's well known in the field that string theory hasn't had any experimental evidence or proven anything despite over 40 years of uncounted people unfortunately devoting their careers to it. It's basically just interesting math that looks elegant on paper, but very *very* likely is just a rabbit hole of "fantasy" physics.
@@FordFourD-aka-Ford4D you could have said that about robotics 2 years ago and look at it now, all of those people that devoted 30, 40, 50 years of their lifes, it was all worth it. You never know when youre near a breakthrough, we have to keep pushing, on all frontiers, and that includes the unlikely ones. And maybe string theory is not as unlikely as we tend to think, it could be just incomplete, not wrong
opinions and facts... sometimes we confuse the two.
@@ChrisCDXXIt's not just an opinion. The Theory is untestable. You can find several scientists expressing pretty much what the OP just said on CZcams.
I first heard Michio Kaku on an old late night radio show called 'Coast to Coast' with Art Bell. It was fascinating to here Michio talk about physics for 2 or 3 hours.
Oh my gosh, I remember that radio show! Hadn’t thought of it in years. I want it back now. 😊
Still listen to Art on a regular basis. My favorite shows are Mad Man Markum and Andrew Basiago time traveler
Thank you so much! If I had a teacher like you, I wouldn't have failed Physics.
That's actually kinda interesting!
The professor anyone would have dreamed to have
_Everyone?? You must be kidding. He’s a reincarnation of Einstein, in an asiatic, or slit eyed version._ 😂
I can feel warmth and kindness in his voice.A good man.
A lucid and simple explanation denotes true mastery of a subject.
He’s presenting string theory as though it’s been verified by extensive experimentation and is an accepted theory. It’s not
In fact at this point it's discredited.
Exactly just elegant math showing off
was looking for a comment like this!
The question was to explain String theory, which he did. Nothing about this video is pretending to assess the theory's validity
He literally starts off saying you can put an electron under a microscope as if we could even fathom of a way to view electrons with a microscope
String theory should have died a long time ago, but too many careers are based on it.
It's too rich to die. It just shouldn't be taught as fact like Michu Kaiku and others who've based their entire careers behind it do. It's a good framework as long as you keep in mind it's probably not correct.
I too have no qualifications and have strong opinions about physics theories
String theory is nonsense.
Strong theory is... wait for it... a theory. Shocking
@@pipegris
Tell me you don't know what a theory is without telling me
The sign of a truly intelligent person is that they can explain any concept to anyone, knowing how to simplify to make it easier to understand, but also keeping it true.
Dot hits dot that hit multiple dots and those dots hits more multiple dots = nuclear explosion
Lol, lmao even
Dot matrix…
Ummm okay, I think he intended to explain something different
Have the people at CERN and the other 30,000 particle accelerators on Earth heard about your Big Bang theory? Or are they too busy hiding the Dark Matter Mass they create everyday.
Wait… don’t you have to split some dots before you can actually get a nuclear explosion 💥? I’m pretty sure dots bump into each other infinitely every single day.
If this is the case why don’t they just teach it like this to begin with instead of confusing people with dots 😭
Because string theory is not even close to be proved at all, it's just one of many theories of everything, none of which is proved yet.
Because we don't really know if they are, its just a theory.
@@TON__618. Yes that is true, although in science 'theory' refers to something that has proof and plausibility backing it without being a fully proven fact. The normal use of theory would actually be a 'hypothesis'.
@@SnowRose-wn6gj Well, while you are right we need to call it a theory even if it is not. This is because it is the only "hypothesis" that can combine all our laws, or more popularly known as "the theory of everything".
@@TON__618. Oh, well then i learned something new today, thanks!
Professor Kaku's class is phenomenal. If you pay attention to his lectures, you will pass his Exams and will be super good with most of what his course material has to offer. His lectures always inspire so many students.
He is great at simplifying an explanation so that anyone can understand it.
String theory is so brilliant that it can’t be tested and has never produced anything.
You obviously have never researched this topic, and decided to sound ignorant by commenting on something you don’t understand
@@amarug okay so basically, the problem with our current standard model of particle physics and Einsteins GR is they fail to describe gravity at the quantum level, the math breaks down. String theory, or now superstring theory, allows gravity to be described in the quantum level, it predicts the graviton. However, there are some problems with this theory(not in the scientific sense, it’d be more of a hypothesis), I’ll just name one, because it can get very long explaining this. The main problem you could say is that the string theory and superstring theory predicts (or requires there to be) that there is 6 other dimensions, or 10 total dimensions of our universe. I’ll stop here because it’s getting long 😂
@@AstronomyAdmirer ok but what are the experimental tests which confirm it is actually true and not just a mathematical model?
@@ow7398it's called string THEORY
it's a THEORY, a POTENTIAL EXPLANATION.
it's there to fill a gap, which it does, while opening the door to other questions.
it's always been this way in all science. i don't see where the problem is.
@@rami-succar7356 "A scientific theory is an explanation of an aspect of the natural world and universe that can be (or a fortiori, that has been) repeatedly tested and corroborated in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results."
String theory is an untested hypothesis. More and more physicists are abandoning the idea as a wild goose chase. It's just a super complicated set of mathematical calculations that involves more than 11 dimensions. Michio Kaku (the man I love and respect) is always super excited about these untested ideas that border on science fiction rather than reality. So no. We won't see vibrating strings. Thanks
the math isn't worthless, they are educated calculations offering worthwhile information that these patterns exist at the subatomic level.
You won't ever see a string because you can't see in the 4th dimension. I recommend you read 'Flatland: A Romance of Many Dimensions'. I think you might find the argument interesting and enjoy the story. Best
@@user-ih3xi7iv9k if we can never observe it that means the hypothesis IS untestable and therefore a dead-end scientifically. And despite it being a proposed "theory of everything" that could reconcile quantum mechanics with relativity, it really seems like that's never going to happen.
@@ebreshea "seeing is believing" said the Blind Man.
@@user-ih3xi7iv9k if you believe in something despite zero evidence that isn't science, it's faith.
He just said (in his theory (of everything?) That everything is just A DANCE of ENERGY, at different levels & patterns. That's variety of strings to say in short. But i think String is open-end vibrating ENERGY, not material particles (electron existence is limitation/boundary) which are LOOPS of many kinds.. another book (?) to be written.??
Michio Kaku's physics videos are fascinating.
I crochet things, and often think that I am using string theory 😂
I would LOVE to hear a full on science convo about many topics btwn Michio Kaku and Neil DeGrasse Tyson 🤧✨
Yes! Great idea. Let Eric Weinstein be the moderator, pose questions, etc. It would be fascinating.
Neil would be exposed
@@Farsider3955I see what you did there, well played...
Why am I hearing around the traps that string theory represents the old guard who is holding science back.
Ye some people think that the universe cares for their feelings.
"around the traps?"
What does this mean?
This is why the world needs Prof. Michio Kaku.
As a Chemist , I find his explanation quite fascinating makes me see Chemistry in a different light especially all aspects that relates to electrons which is a lot 🥰
The answer to the question was supposed to be "probably yes - there are people who know of people who can explain string theory so even the guy asking the question would understand it" Michio Kaku hasn't answered that question at all 😮
I like the way he presents hypothyses and interpretations as unquestionable facts.
Pretty common amongst string theorists.
You know someone is a brilliant expert when they can explain in a few minutes really complex concepts in their field of expertise in simple easily understood terms.
A real Genius that can explain clearly . It was a pleasure to hear this.
Many people calling him legend even without knowg string thing which wasted 40 50 years of scientist
There is no such thing as wasted hypothesis in science, either you discover something or discover a way to not getting something new, then you have gotten some new knowledge, just not the expected one.
I know string thing.
@@spockers as foretold
I thought string theory was pretty much a dead end at this point...
This
It is
Why?
@@paulwalked5810it cannot be tested
@@paulwalked5810I'm assuming because it only ever remained a theory and we have no way to know for sure if it's real.
This video sent me down a 2 hour long rabbit hole learning about string theory and quantum physics
Someone who can explain something very complex in simple terms is someone who truly understands what they are saying. Absolutely brilliant.
I always like seeing Michio Kaku! 💜
Yes, I agree. It's been a while for me...time to go on a physics tangent/rabbit hole now...
He needs a labcoat. A drinking habbit, and a grandson named morty.
interstellar?
@@Maxtherocketguy lmfao
And a fantasy world in which everything that he hopes to be real can be.
But seriously, this guy is like a bottomless barrel of misinformation, not a IRL Rick Sanchez
I could listen to Michio all day. He is Brilliant man.
God bless you Michio.
Debbie T. ❤
Just adore him. I love all things science. He breaks it down so well. He's another reason I love science.
I'm a simple man. I see Dr Kaku, I hit "like"
I thought string theory was very speculative ?
It is thus far, entirely speculative.
As every theory of quantum gravity is speculative so is string theory xD
It is, but seem so happy talking about it, that people just let them tinker with their toy models
Not really. We know string theory fits our current model.
@@AlexDeLarge1Well the argument is that it doesn't fit our current model except where we've adapted theory to fit. String theory has produced nothing, none of the experiments that SHOULD prove its predictions have done so
This man practically raised me. I miss when science and history channels weren't all conspiracy theories
Michio, that is the most superb explanation and demonstration, I have ever witnessed. Sure wish there were more Science Professors in our World that were capable of teaching on basic students levels. Then we would have many more great Scientists. Science is fun and should be taught in a fashion we can absorb readily. Thank you 🙏🏻 for this reel.
That’s mind blowing
Michio, you are GREAT at explaining the COMPLEX in a SIMPLE way, so 🫵🏼 are a GENIUS. I especially appreciated you sharing years ago, that we exist within a GINORMOUS Galaxy, Universe and beyond; hence, it’s extremely arrogant to believe that we’re the only ones in town.
I’ve had many earthly and otherworldly, vivid dreams of numerous realities-within parallel and alternate universes-as early as the late nineties, for a week in 2001, and mostly within the past 13 years.
And this included being within different worlds, seeing MANY different extraterrestrials, and even interacting with dozens.
This guy is a absolute living legend !
Was, he's been too deep down the lunatic quack consciousness rabbit hole for years now, nobody respects his current takes in the community
Have been a big fan of Michio Kaku for more than a decade now, ever since I saw him in documentary series how the universe works
Bro im a teenager and im not even fluent in english and i undertood this. THIS is a good teacher
I have never known this man’s name and I have seen this man everywhere. I am so glad to finally learn his name. He is awesome!
What if i zoom in on the rubber band
Then it'd never give you up or let you down
I simply ADORE this guy! Neil, Michio among others are my favorite go to everything!!
LOVE this man. He makes the science of life and our world easy to understand, instead of wrapping it all in as much complexity as possible to make himself seem greater, as most do. He's blessed, and we are blessed through him. 😊
These superminds who can explain a subject in simple terms should be filmed & their "lessons" should be used in Schools.
Some people are gifted & can explain the most complex subjects simply
String theory is not even real. If you want to understand the unreal topic, go watch some standup comedy.
It’s important to remember that this is just a theory it hasn’t actually been proven yet
Not even that
Theory in science is the highest level of veracity an idea can achieve. It doesn't mean unproven -- it means the opposite
@@AnarexicSumo and that's why string theory isn't really a theory. It doesn't provide any "if you do this then you should get that" predictions, it's just a bunch of ideas floating in the air with no attachment to what we can actually do with them or what observations we can make. It's not taken seriously by other physicists
It's not just a theory, if it were then it would be amazing. It's just a hypothesis.
Hands down the best explanation of string theory that I've ever heard!!
I've heard of string theory since fifth grade (over ten years ago) and never thought that it was as simple as this. Wow this is completely new to me and it's breaking my brain a bit
Thanks Michio Kaku for explaining string theory in layman's terms, just plain English. This is very helpful!
The strings only exist in their dreams
This scientist is my childhood, loved watching show about mysteries of space with him and his colleagues
He is the best at explaining complex ideas in a basic way ANYONE can understand.
He is not a pseudoscientist. The difference between a scientist and a pseudoscientist is in how they apply the science method. A fringe theory is still a scientific theory if it follows the scientific method, which he does.
Who said string theory is pseudoscience? It’s not. It’s just a fringe theory that’s become less and less accepted over time.
The scientific method usually relies on evidence, something which string theory lacks
Not if it's The Science. See Dr. Fauci
what?? who even thinks he's a pseudoscientist?
Physicist and Nobel Prize laureate Roger Penrose says we need to abandon string theory. He disagrees with Kaku. String theory is based on fantasy and hocus pocus.
Thanks...
Just love the Michio Kaku explanations. Is so simple!
Honestly thank you for that. You dumbed it down for non geniuses like me. And you were able to do it in a minute. Thank you so much
Hasn’t string theory lost favor?
I think so, but we don't have a proven grand unification theory to take its place either, so depending who you ask, you might hear it's not entirely off the table yet. Who knows, maybe it's not viable in its current form but tomorrow they might discover something or reformulate it in such a way that gains traction again. Idk, I just hope they find the answer in my lifetime x'd
Sooo alchemy was possible all along?
I appreciate this video. It’s one thing to be smart. It’s another thing entirely to be able to effectively explain what you mean to somebody who has little to no knowledge of what you’re talking about. Well done, Mr. Kaku.
I love the fact that I’ve been watching this guy since he was a young guy popping up on science shows on network TV.
He’s explaining this as if it’s a proven fact
How do you know it's not.
@@rickdeckard9810 string theory is theoretical physics. It's mathematically sound but it hasn't been proven experimentally. Don't expect this being taught in school instead of traditional particle physics for the next decades
@@rickdeckard9810I mean even if it's a hundred percent accurate it is absolutely not proven fact.
Hats off legend
wow, the most useful minute of my life. I want someone to explain all physics this way.
Dr Kaku is by far the best at explaining physics to a layperson. Brilliant mind, but down to Earth.
My favorite physicist, him and Tyson.
30+ years and no testable hypotheses for String theory. That's a science fail.
So far...
This is what common people need complex problems explained in a simple manner.
He explains this portion well, but it's also about connectivity. When we look at the space between atoms, sometimes we wonder what causes bonds, and these questions repeat for much larger distances, and quantum distances. Why are some things held together? String theory is just one theory that kind of suggests that particles like to hang out together. We then ask ourselves if there is anything outside of the universe's strings? Well, there could be more strings. I don't firmly believe in string theory as it pertains to physics, though. It's almost more like philosophy. M theory is similar, but it's about membranes. Like...what if our universe is in a giant bubble or membrane. And that membrane has the potential to bump into other universes or membranes? In theory, could we ever punch through those membranes? Could we ever reach them to determine whether there's a multiverse? Could we establish whether they're there or not using math or physics? And yes, they have been debunked or at least set aside because we can't really test them. Some still think that a black hole is a point where two membranes are resting/pressing against each other. We could account for the flattening/inverting/coning of information. Sort of.
This over-dressed flea market salesman is saying funny things. Anway, gotta get back to the real science...
Do you have a PhD and teach physics? He's allowed to have a theory. Even some of Einstein's ideas weren't proven until after his death.
The real science is his dotted tie. 😮
This guy and his long buried string theory. Give it a rest. 😂
I am so glad he cleared that up!
That was a great explanation! Thank you
String theory is bunk. No actual physicist thinks it is right anymore.
Even Einstein wasn't proved right about a number of things until after his death. 🤔
Yep
String theory hasn’t gone anywhere in decades because it’s just wrong. This guy sure turned into a hack
There aren't many ways of illustrating how fields create particles and the math of micro interactions often involves having 3d planes interacting with many others(i don't know all the terminologies/names) and reverberations between these are what they think is the key.
Actually, just like any other theory of everything, the problem is they can't find a way to either prove or disprove the theory, so you can't really know anything until they figure out how to test it. Mathematically is promising.
@@TheVochiba Yes that is true but hard to swallow, string theory works so well but real life is not mathematical perfection. Am currently studying physics and i hope ill get to study string theory even if im not doing great now
The Tao cannot be explained.
Great explanation of aspects of Orbital Theory, too👌💯
I just absolutely love your knowledge to be able to retain the vast amount of things that you know, it's a blessing. would love to meet you. Your so kind and gentle easy to listen to. I wish that there were more, kind teachers like you. Could you imagine how smart people would be if we had teacher's like you... I've had so many give up on me... as a kid I stopped trying to a point. When most of your school life was in Learning Disabilities (LD) Classes just because I was a slow learner. Kinda gave up🤦♀️🤷♀️
Seeing how old he got 😔 he was a legend when I was a kid.
This feels like the opposite of Feynman who would start with "What confusion does the theory resolve and what novel testable predictions does it make?"
This was incredible understandable and interesting!
Being able to explain this kind of concepts like this is one of the toughest jobs in science
This man is a treasure that we must protect at all costs.
So that’s what’s been holding me back. Thank You.
I get all that, what I don’t get is a) how something can wiggle differently at a quantum level and b) why slightly different wiggles give such drastically different properties to the particle
So wonderfully clear. Thank you!
