HU, really? well, gravity doesn't exist. any object which is heavier than air and which is unsupported, has a natural tendency to fall by its own weight. for ex., an apple, when ripe, loses hold of its stalk, and, being heavier than air, drops as a matter of necessity, to the ground, totally irrespective of any attraction of the Earth. bonus video. ua-cam.com/video/vyAh9OENJPU/v-deo.html

I think the reason the kid came off as knowing more than the teen is because she was less afraid to say something 'wrong'. I'm sure the teen is very good at physics at school but she's intimidated talking to someone whose job it is to study physics.
l o l : Max’s Hut was only pointing out that the little grade school girl came across brighter and seemed to have a better grasp of what she was hearing than the high school girl did. And I agree. My first thought after listening to the high schooler was surprise that she’s actually TAKING physics classes, because seemed to completely miss the point of some of the questions she was asked.
Being told “we don’t have that yet” is absolutely terrifying yet interesting that we are still learning things today. Makes me wonder where technology and knowledge will be in say 50 or 100 years. Cool !
Gravity itself isn't a theory, but we have scientific theories to describe how this fundamental interaction/force works. For example, Einstein's general relativity is a theory of gravity. The theories are tried and tested experiments to explain why and how gravity works. So Owen's comment doesn't make sense in that regard. If they're saying it's a theory in the colloquial sense - that it's a hypothesis/guess - that doesn't make sense either. Gravity is a term we give to a phenomenon that exists. The theories are what we use to understand what's going on, in accordance with the scientific method, etc.

That level is available to everyone (of normal cognitive ability) if they are WILLING to put the energy into learning. Helps if you love the subject matter... and don't live in America where Universities are for rich-kids-only.
@xxGodx incorrect, I'm dumb but understand most of this because this knowledge is available if you search for it online. Insulting other people by saying they're stupid is also not a good way to try to prove your point.
Honestly I liked when she was talking with the expert because they both understood each other very clearly, which is why it was a conversation. It made me realize several things and also made me question so many other concepts.
This also happens with me when I talk about computers, not OH INTEL 10 cores, OH AMD 12 CORES, not but actually talking about the silicon density of the DIE and how the traces are shaped and the fact if you go too small atoms can move to other traces causing a surge. This is nice because you share knowledge and then you come up with a conclusion, it's like syncing your information with someone.
@@dynamics3261 She didn't understand him very clearly. She said what if it turns out that the world is 2D and we are living in a hologram? Nobody suggested we are living in a hologram, so she clearly had long lost him. What is being said is that just LIKE with a hologram (= analogy, not identity), there is more information in a 2D representation than meets the eye, basically. Because it is counter-intuitive to find that you cannot pack more information in to a 3D space than fits on the enclosing 2D surface of that space, e.g. a box or a ball shape. So the similarity to a hologram is that there is more information on the surface of an object than you'd expect. But a 3D space like a box, a room or the entire universe are truely 3D, unlike the hologram. - You cannot turn your credit card around to check and see what is at the back side of the security hologram or take a side view of a hologram - but of course you can take a look at the back of any 3D object in the real world though. The world is not a hologram, the analogy is aiming at the fact that just like with a hologram, any 3D object in the real world has a surface that can tell you about the information inside that 3D object by looking at its 2D surface, only. - That does not mean a 3D object IS a 2D object and nobody suggests that, but many people hear "holographic universe" on the Discovery Channel and jump on it, because they think they just heard about something crazy-amazing, well, on the Discovery Channel. (it still is amazing, though!) If you are interested in a good explanation, there is a series of talks by Leonard Susskind on UA-cam, The Black Hole War, where he narrates a decades-long struggle with Stephen Hawking on all things Black Hole and this series goes along with his book by the same title, which is an interesting read also for laymen. Try the UA-cam video first, it's free ;)

Wow, this professor's narrative is so captivating. Makes you think about the impact a good teacher can have on their students' lives. I'm a linguist but understood most of what she said. And not because of my science teachers - they were lousy and uninspired. My mom was a physicist and after each boring lesson at school I'd go to her for a proper, fun explanation. Unfortunately, the rest of the class did not have a physicist mom.
@@Richardiba Maybe this time, but she has had exposure in context, and the girl will hear it again in a similar context in the future, and the word will eventually acquire meaning to her.
I do that with my niece and nephew. Sometimes it's surprising what they retain. It's also important for children to meet a lot of people, so they can learn all kinds of words and sayings. A broad vocabulary also comes in handy when learning second languages. If the children don't understand, they will either drop the topic or inquire further, depending on temperament and intelligence.
Fantastic review for me. Received my BSEE in 1972 and haven't reviewed temperature in statistical thermodynamics for half a century or considered it to be analogous to gravity in the way she said it. The expert was really good; he should put out scientific vlogs! But I have always loved science, even retired now at age 73.
The most interesting part of this is that none of these explanations are actually wrong, they are just more or less complete. Even the expert one will not be complete until we develop a theory of quantum gravity, and even that is likely to open up new questions.
Nathan Desta I don’t accept that it’s impossible to ever understand it 100%, or that we never will. I acknowledge that we might never do so, but I don’t see it as an impossibility beyond things like the heizenberg uncertainty limit.
Nathan Desta yes, but it could take millions of years. And thats if human kind isn’t extinct. In a couple million years, the moon will glide away and there wont be any life left on earth.
@@NoNewfriendss Brans Dicke is the way. Einstein himself practically admitted that general relativity could not accurately describe quantum mechamics and thus is flawed. Everyone thinks that Einsten created General Relativity and stopped doing anything, when in actuality he kept researching unified field theories for 30 years. Now CERN and others found some anomalies and ended up with the Higgs Boson scalar field, which was theorized by Einstein-Bose' Condensate. Einstein had to add those because it (His UFT) would've been the same as Nordstrom's theory of gravitation
I could actually see Matthew (Expert) opening up throughout the interview. It was almost like he's gotten so used to dumbing everything down for whoever he meets on a daily basis, that it's a tiring norm for him. Then when he realized he was in the presence of somebody who could near enough fully understand the complex ideas they discussed, he came right out of his shell and enjoyed himself for the remainder of the interview and that warmed me a little
Love this and totally agree I think it's just about how bright humans get about finding someone with the same passions as them. Having such a niche interest like Matthew's can prove lonely at times, so when he found someone that matched his intellectual level, he couldn't help but be fully engaged with the conversation
I occasionally come back to this video because of the beautiful explanations, last time the penny dropped for me on Einstein's relativity theory during the conversation with the college student. This time around I had a similar experience listening to the conversation with the expert about quantum mechanics and the relation with gravity. Fantastic video!
Level 1: totally got this Level 2: totally got this Level 3: this is my level Level 4: understood 50% Level 5: i dont know anything about gravity anymore and it looks like theyre flirting
It’s funny because I understood a lot of the stuff of the 5th level just off of watching UA-cam. Physics is confusing but once you grasp a relatively difficult concept you feel like a genius.
24:46 the look on his face after she called him a scientist is so heartwarming! I dont know how this young man thinks of himself but as a grad student impostors syndrome is sooo real, you never feel like you’re enough despite how much you know. I imagine that getting called the thing you’ve been trying your whole life to become by someone who is that very thing and an expert at that, must feel pretty special.
If you can capture the child’s imagination and teach effectively a concept such as gravity, while simultaneously evoking pertinent questions and realizations, you have started the child on a lifelong journey of learning. She is an awesome teacher.
Ya know, I gotta say as someone who hasn't gone to college yet and learned purely off astronomy articles and youtube videos, I only started learning a bunch of new stuff once we got to the expert part. Pretty proud of myself. I know you dont care but hey, pat on my back 😂

The commenting on youtube is done by using the same 7 phrases over and over again with slightly different variations. Everybody has an opinion, and everybody will voice their opinion, despite no one actually caring.
The child was really good but I think maybe they should have had two children. The one they had already had a pretty decent grasp of what gravity was. I think it would have been interesting to hear the expert explain it to a kid who knew quite a bit less.
well, human math is what describes the Universe, under human capabilities, in reality, the universe doesn't use human math. math ends when it meets chaos. but in the real universe chaos does not exist, only order.
Wow that last expert conversation blew my mind. Never thought I'd end up grateful for taking up the sciences. I didn't understand a thing properly towards the end but at least I can understand the terminology and vague ideas so I'll consider that a win.
Well to be fair isn't gravity a fairly complex subject? I thought the idea is that we understand how gravity functions, how it affects certain objects, but not what it truly is.

Truly fascinating. Losing it here at Grad level. She is an amazing teacher. Guess I understand things in an abstract or conceptional level but cannot even imagine demonstrating this mathematically.
@ViribusEtVirtusSolaris The concept of gravity is brought out early in school but never expanded on. Basically the teacher would pick up a pencil, let go of it, and say "this is gravity," and that is it.
@@AGONEY97 The fundamental explanation, “Apples fall because.. gravity.” is a faith based belief. First, they need to disprove that apples fall because they weigh more than air, and without the use of any other force in their demonstration. The claim that ‘it’s impossible to eradicate gravity and show objects float’ does not excuse the fact that using another force in a simulation of demonstration, is the point at which the claim has injected ‘faith’ into its explanation.. faith that the visual result being shown isn’t actually due to some other comprehensible factor.. such as weight, force, speed, density, buoyancy, etc. This acceptance of ‘faith’ as to ‘how’ always ends up being contrary to our basic human logic & senses. All children start out asking how people living opposite them, upside down, on the other side of a spinning ball.. don’t fall off.. meaning THIS demonstrates our TRUE human understanding of ‘basic human logic’.. that is, our body weight vs./air is what keeps us upright and grounded, ..not gravity. Science has yet to discredit this fundamental conception with any independent proof of a gravitational reality, yet instead, bypasses the natural expectation of demonstration by starting with the premise, “we simply know gravity exists, or else we would float off.” Again, there has been NO demonstration which disproves the possibility of alternate factors, and since no one can re-create for themselves a demonstration of gravity (or a lack there of) here on earth.. The fact remains that gravity is simply a text-book/TV performance based faith, no more elevated in logic than belief in the Bible. (which btw, doesn’t result in the delusional questioning of whether our reality is actually a 2D hologram, floating amongst black hole, matter dissolving, devoid of space/time vacuums.) 😑
@@purpleXpotion Well, no. Gravity has so much evidence that it’s a fact. You don’t believe in gravity cause it’s written down on a book, you believe in it because of a combination of your own observations and others. Such as the people who saw the gravitational redshift to prove Einstein’s description of gravity.
Yeah like people talking about being in their 20's or 30's. Never heard someone rounding a height to feet lol. If anyone ever asks me I'm in my 6's lol just barely.
Level 4 isn't university talk... I am a physics student and I can assure you, you do not talk about things but rather just calculate and calculate more. The explanation she gave is much easier to wrap your head around, even with the last guy than it is when you get it explained in university. Usually it goes like this: The professor calculates things and just reads out what he or she is writing. Then they give it a name and a bit of history about it, if you're lucky. After that the next topic is "discussed". You'll have to turn in weekly assignments and they again, are just calculations but the lecture isn't nearly enough to actually solve them so you go online and read about it... a lot. That's where you get most of your information and actually learn about what does what. In short, university talk would be a level 7 or 8 on your scale.
@@mephistovonfaust maybe it depends on the university, professors and such. My professors seem to enjoy explaining a bit more than calculations and such, feels like nerds showing off their interests and I like it. They made maths fun somehow, except the exams which majority failed :^)

The simple fact is that we understand the rudimentary physical repercussions of gravity, not how those things manifest. Just because you can drive a car doesn't mean you know how every part of your vehicle operates.
@@gregoryjones9506 in this case it should be, you can drive a car, you know the parts and how they interacts, but don't know the quantum level of the interactions. Because we know gravity on terrestrial and celestial scales, gravity on moving objects, gravity on very fast objects, but our current model breaks down on the very small level, in the centre of a black hole for example.
That's how it is. When you don't know much, you don't know how much you don't know either. When you've learned much, you have also learned how much you don't know. This is why fools think they're experts.
Jawad, gravity doesn't exist. any object which is heavier than air and which is unsupported, has a natural tendency to fall by its own weight. for ex., an apple, when ripe, loses hold of its stalk, and, being heavier than air, drops as a matter of necessity, to the ground, totally irrespective of any attraction of the Earth. bonus video. ua-cam.com/video/vyAh9OENJPU/v-deo.html
Absolutely fantastic. I’ve always wondered why more videos didn’t use this type of format, which is excellent for really understanding a topic (minus the math of course). Keep these coming - I will watch every one!
When you reach Level 4 and 5 you can sense that she's stopped explaining things to the other person and they're just explaining things to the audience instead.
At level 4, she was more talking with the PhD student than determining his understanding of gravity, and so they did not touch upon complicated aspects of it. Only at level 5 did I start to get lost at some parts, but I was still able to understand some things. And I do not have a masters or doctorate degree, in any field, much less physics. I just watch UA-cam videos.
Yeah level 5 was a meeting of minds between 2 real experts. I could follow what they're saying, it's just that for now they're jiving in this language thoretical physicists have created that currently is getting us nowhere, and has been getting us nowhere since Einstein. Tuppence in the slot ;)
We surely will never understand anything, because we cant be sure we reached the "end point" of science. But we think, we can always refine our theories... Thats what they are talking about.
@@Joyexer the quantum theory of gravity will actually be a very giant step ahead, we'll understand a lot of things after it's established. A possible theory of everything

@@eagle3676 No, that's a dangerous perspective to look at these things. I bet you're not an expert on any of these things and are approximating what so many of these novel theories mean. We actually have come to understand a lot more than we did a hundred years ago. With the discovery of chaos theory, scientific theories actually have a bright future. Look at where we are today technology wise and where medical science has come to and we put a man on moon and next is mars and a human made probe is right now outside solar system. These are achievements and we understand a lot better now. Surely, we're nowhere near understanding it to it's full capacity? but we've done progress and that's certainly not a reason to stop thinking and perpetuate this type of mentality. And I don't know why ppl like you think science (physics) is an open book and everything's just supposed to be discovered right away in an year or something, it obviously takes time. We're doing pretty good for beings this small compared to planetary and cosmic scales.
Level 1: gravity is when the earth and the moon is pulling us at the same time. Level 5: Maybe the earth is a hologram and the universe is two dimensional.
The explanation of the relation between space and time in that light speed measurement situation is actually mind-blowing. It made me inuitivitely understand the idea behind theory of relativity :o
Child: if there is enough gravity, we couldn't even lift our arms! Grad student: If there was enough gravity we would be smashed and shred into particles and become one with the mass.
Me: If there was enough gravity, the sun would collapse into a black hole and would swallow earth due to increased gravity, at least after we get crushed into the core of the earth.
@@4TH4RV That's nonsense. You are wrong. In reality, our sun can never ever become a black hole. It is too small of a star to ever become a black hole. After sun runs out of energy and explode due to gravity, it will become a white dwarf, not a black hole. And Wesley is correct. With enough gravity, any matter can become a black hole regardless of its mass. If the sun were to magically gain enough gravity (i.e gravity of star R136a1), its matter will get squeeze into really tiny space and form a black hole. Black holes are formed due to gravity. Gravity so strong that even light can't escape it. If a coin somehow gets enough gravitational force, it will form a black hole.
@@wesleyteh1901 Even if the sun became a black hole (hypothetically) gravity does not increase. The gravity becomes concentrated at the center of a black hole.
I love these videos! I loved the reminder of the hologram part. I've seen it in documentaries before and it aligns really well with the whole spiritual concept of how existence and conciousness works. The pictures are very similar and I love how old intuition based observations start to get more and more reflected in science.
Love how even the child explanation is not infantilism. Both the astrophysicist and the child have a respectful and mutual participation. There's no unnecessary giggling or filler questions like "Aww what's your favourite planet?" Kids are smarter than you think.
I hated that, as a kid I always was smarter then the rest of my peers and got hyper-fixated on something so talking to adult was always difficult because I wanted to talk to them like an adult but they’d always talk to me as a child. My dad was the only person who really talked to me like an adult.

Being told “we don’t have that yet” is absolutely terrifying yet interesting that we are still learning things today. Makes me wonder where technology and knowledge will be in say 50 or 100 years. Cool !
gravity is still a theory
How is it a theory?
Gravity itself isn't a theory, but we have scientific theories to describe how this fundamental interaction/force works. For example, Einstein's general relativity is a theory of gravity. The theories are tried and tested experiments to explain why and how gravity works. So Owen's comment doesn't make sense in that regard. If they're saying it's a theory in the colloquial sense - that it's a hypothesis/guess - that doesn't make sense either. Gravity is a term we give to a phenomenon that exists. The theories are what we use to understand what's going on, in accordance with the scientific method, etc.

I loved seeing her communicate with the expert. Up until then, she was giving a lecture. Suddenly, she was having a conversation.
Honestly I liked when she was talking with the expert because they both understood each other very clearly, which is why it was a conversation. It made me realize several things and also made me question so many other concepts.
it remembers me the video about harmony, where speaking to the expert they actually just play together some jazzy harmonies, loved that too
This also happens with me when I talk about computers, not OH INTEL 10 cores, OH AMD 12 CORES, not but actually talking about the silicon density of the DIE and how the traces are shaped and the fact if you go too small atoms can move to other traces causing a surge. This is nice because you share knowledge and then you come up with a conclusion, it's like syncing your information with someone.
@@dynamics3261 She didn't understand him very clearly. She said what if it turns out that the world is 2D and we are living in a hologram? Nobody suggested we are living in a hologram, so she clearly had long lost him. What is being said is that just LIKE with a hologram (= analogy, not identity), there is more information in a 2D representation than meets the eye, basically. Because it is counter-intuitive to find that you cannot pack more information in to a 3D space than fits on the enclosing 2D surface of that space, e.g. a box or a ball shape.
So the similarity to a hologram is that there is more information on the surface of an object than you'd expect. But a 3D space like a box, a room or the entire universe are truely 3D, unlike the hologram. - You cannot turn your credit card around to check and see what is at the back side of the security hologram or take a side view of a hologram - but of course you can take a look at the back of any 3D object in the real world though. The world is not a hologram, the analogy is aiming at the fact that just like with a hologram, any 3D object in the real world has a surface that can tell you about the information inside that 3D object by looking at its 2D surface, only. - That does not mean a 3D object IS a 2D object and nobody suggests that, but many people hear "holographic universe" on the Discovery Channel and jump on it, because they think they just heard about something crazy-amazing, well, on the Discovery Channel. (it still is amazing, though!)
If you are interested in a good explanation, there is a series of talks by Leonard Susskind on UA-cam, The Black Hole War, where he narrates a decades-long struggle with Stephen Hawking on all things Black Hole and this series goes along with his book by the same title, which is an interesting read also for laymen. Try the UA-cam video first, it's free ;)
I skipped straight to expert because I know the rest is painful. Talking to an expert she started to look pretty silly. It was actually a waste to time because she did not explain anything.

Fantastic review for me. Received my BSEE in 1972 and haven't reviewed temperature in statistical thermodynamics for half a century or considered it to be analogous to gravity in the way she said it.

The most interesting part of this is that none of these explanations are actually wrong, they are just more or less complete. Even the expert one will not be complete until we develop a theory of quantum gravity, and even that is likely to open up new questions.

Then when he realized he was in the presence of somebody who could near enough fully understand the complex ideas they discussed, he came right out of his shell and enjoyed himself for the remainder of the interview and that warmed me a little
Love this and totally agree
I think it's just about how bright humans get about finding someone with the same passions as them. Having such a niche interest like Matthew's can prove lonely at times, so when he found someone that matched his intellectual level, he couldn't help but be fully engaged with the conversation

First, they need to disprove that apples fall because they weigh more than air, and without the use of any other force in their demonstration. The claim that ‘it’s impossible to eradicate gravity and show objects float’ does not excuse the fact that using another force in a simulation of demonstration, is the point at which the claim has injected ‘faith’ into its explanation.. faith that the visual result being shown isn’t actually due to some other comprehensible factor.. such as weight, force, speed, density, buoyancy, etc. This acceptance of ‘faith’ as to ‘how’ always ends up being contrary to our basic human logic & senses.
All children start out asking how people living opposite them, upside down, on the other side of a spinning ball.. don’t fall off.. meaning THIS demonstrates our TRUE human understanding of ‘basic human logic’.. that is, our body weight vs./air is what keeps us upright and grounded, ..not gravity.
Science has yet to discredit this fundamental conception with any independent proof of a gravitational reality, yet instead, bypasses the natural expectation of demonstration by starting with the premise, “we simply know gravity exists, or else we would float off.”
Again, there has been NO demonstration which disproves the possibility of alternate factors, and since no one can re-create for themselves a demonstration of gravity (or a lack there of) here on earth.. The fact remains that gravity is simply a text-book/TV performance based faith, no more elevated in logic than belief in the Bible.
(which btw, doesn’t result in the delusional questioning of whether our reality is actually a 2D hologram, floating amongst black hole, matter dissolving, devoid of space/time vacuums.) 😑
@@purpleXpotion Well, no. Gravity has so much evidence that it’s a fact. You don’t believe in gravity cause it’s written down on a book, you believe in it because of a combination of your own observations and others. Such as the people who saw the gravitational redshift to prove Einstein’s description of gravity.
“Do you know how tall are you?”
“I’m in the 4’s”
I thought that was adorable.
Yeah that confused me cause she was at least 1.1m, then she said 4'2 and I realised what she meant.
2:30 Omg that squee when she saw she was a little taller! I melted! 🥰
Yeah like people talking about being in their 20's or 30's. Never heard someone rounding a height to feet lol. If anyone ever asks me I'm in my 6's lol just barely.
@@ronray3293 creep
@@ronray3293 um what
Level 1: kid show
Level 2: youtube video for online class
Level 3: documentary
Level 4: lecture
Level 5: *roMaNtiC nErDs' dAte*
Level 4 isn't university talk... I am a physics student and I can assure you, you do not talk about things but rather just calculate and calculate more. The explanation she gave is much easier to wrap your head around, even with the last guy than it is when you get it explained in university. Usually it goes like this: The professor calculates things and just reads out what he or she is writing. Then they give it a name and a bit of history about it, if you're lucky. After that the next topic is "discussed". You'll have to turn in weekly assignments and they again, are just calculations but the lecture isn't nearly enough to actually solve them so you go online and read about it... a lot. That's where you get most of your information and actually learn about what does what.
In short, university talk would be a level 7 or 8 on your scale.
@@mephistovonfaust Precisely. That's one of the reasons I quit studying physics, 35 years ago :)
@@mephistovonfaust yeah I’m never studying physics
@@mephistovonfaust maybe it depends on the university, professors and such. My professors seem to enjoy explaining a bit more than calculations and such, feels like nerds showing off their interests and I like it. They made maths fun somehow, except the exams which majority failed :^)
@@AndreasDelleske that's sad to hear. It's a really hard degree to get but the topic itself is just great in general. I wouldn't want to study something else tbh.
My heart kinda made a leap when the little girl realized stuff and was fascinated by those discoveries...I see that in my own kids...most beautiful thing ever.
I love how the level 5 was literally just them having a discussion about how much they don’t know about gravity 😂😂
The simple fact is that we understand the rudimentary physical repercussions of gravity, not how those things manifest. Just because you can drive a car doesn't mean you know how every part of your vehicle operates.
@@gregoryjones9506 in this case it should be, you can drive a car, you know the parts and how they interacts, but don't know the quantum level of the interactions. Because we know gravity on terrestrial and celestial scales, gravity on moving objects, gravity on very fast objects, but our current model breaks down on the very small level, in the centre of a black hole for example.
"The more you know, the less you know."
That's how it is. When you don't know much, you don't know how much you don't know either. When you've learned much, you have also learned how much you don't know. This is why fools think they're experts.
TonyMac I believe it’s called the Dunning-Kruger effect.
In the beginning: "What is gravity?"
In the end: "There may not be the gravity."
@Circular Arc You magnificent idiot. I love it.
@@Herooftheday64 what did they tried to say, i did not understand a word.
Well, there is not. Classical physical existence is overrated.
Oh there is gravity. But its not what a normal person thinks of, its just space time warp
there is no gravity in a way we know it, but gravity the way we know it, describes the effects of gravity
pretty well.

Jawad, gravity doesn't exist. any object which is heavier than air and which is unsupported, has a natural tendency to fall by its own weight. for ex., an apple, when ripe, loses hold of its stalk, and, being heavier than air, drops as a matter of necessity, to the ground, totally irrespective of any attraction of the Earth. bonus video. ua-cam.com/video/vyAh9OENJPU/v-deo.html
Absolutely fantastic. I’ve always wondered why more videos didn’t use this type of format, which is excellent for really understanding a topic (minus the math of course). Keep these coming - I will watch every one!
Tbh to learn it would be just grad and diff expert panels would be 🔥
When you reach Level 4 and 5 you can sense that she's stopped explaining things to the other person and they're just explaining things to the audience instead.
Totally, it's like a respect of knowledge towards the other person.
more of a dialogue between two experts on the matter and we just listening to their conversation.
At level 4, she was more talking with the PhD student than determining his understanding of gravity, and so they did not touch upon complicated aspects of it.
Only at level 5 did I start to get lost at some parts, but I was still able to understand some things.
And I do not have a masters or doctorate degree, in any field, much less physics. I just watch UA-cam videos.
Yeah level 5 was a meeting of minds between 2 real experts. I could follow what they're saying, it's just that for now they're jiving in this language thoretical physicists have created that currently is getting us nowhere, and has been getting us nowhere since Einstein. Tuppence in the slot ;)
She reached her level of incompetence when talking to the PHd and PHd chair. In short, they are peers. So chatting not teaching is the mode.
This “child” is smarter than half the people in my physics class
and probably more fun to teach
Yes
The child knew *way* more physics than the gymnast 🤣
@@ronray3293 Not to mention they gave the same explanation when asked at first.
8 years of American education for ya.
are you in the special ed physics class or something?
Level 1-4: "So this is how it's all works"
Level 5: "We don't actually understand any of that..."
We surely will never understand anything, because we cant be sure we reached the "end point" of science. But we think, we can always refine our theories... Thats what they are talking about.
@@Joyexer the quantum theory of gravity will actually be a very giant step ahead, we'll understand a lot of things after it's established. A possible theory of everything
Mooli Morano lol pretty much
@@deepstariaenigmatica2601 The more you learn about the universe, the more you realise that you don't really understand anything and are just creating models that are a greater level of approximation than the last ones.
I doubt we are even close to understanding the true nature of everything and I sometimes question if any biological life will ever reach a level where they understand the theory of everything
@@eagle3676 No, that's a dangerous perspective to look at these things. I bet you're not an expert on any of these things and are approximating what so many of these novel theories mean. We actually have come to understand a lot more than we did a hundred years ago. With the discovery of chaos theory, scientific theories actually have a bright future. Look at where we are today technology wise and where medical science has come to and we put a man on moon and next is mars and a human made probe is right now outside solar system. These are achievements and we understand a lot better now. Surely, we're nowhere near understanding it to it's full capacity? but we've done progress and that's certainly not a reason to stop thinking and perpetuate this type of mentality. And I don't know why ppl like you think science (physics) is an open book and everything's just supposed to be discovered right away in an year or something, it obviously takes time. We're doing pretty good for beings this small compared to planetary and cosmic scales.
It is great to see young people optimistic and curious about the subject, it creates great hope that one day the youth will solve this mystery.
Level 5: Expert
The astrophysicist: *why do I hear boss music*
😂
🥴 I'm in danger.
BOSS fx Pedals prolly ;)
At last, a worthy opponent!
this is too complicated. someone bring in a toddler.
theres someone higher than toddler.... "im gemini"...
Or a Flat Earther
Same thing
@Mike Jones That's just a fertilised egg cell.
Level 0 should be caveman explaining.
"thing go down. Very up no go down"
Level 1: gravity is when the earth and the moon is pulling us at the same time.
Level 5: Maybe the earth is a hologram and the universe is two dimensional.
Which would make humans holograms as well…
Then what are holograms
Then flatearthers would have actually be right
Yep! That also explains why pizza is so good. Somehow we feel the essence of the universe 😏
@@fuad3756 Holograms are n-dimensional Information expressed on a (n-1)-dimensional "surface".
The explanation of the relation between space and time in that light speed measurement situation is actually mind-blowing. It made me inuitivitely understand the idea behind theory of relativity :o
Child: if there is enough gravity, we couldn't even lift our arms!
Grad student: If there was enough gravity we would be smashed and shred into particles and become one with the mass.
Justin Anderson it’s me. i’m grad student
You still can’t lift your arms so...
Me: If there was enough gravity, the sun would collapse into a black hole and would swallow earth due to increased gravity, at least after we get crushed into the core of the earth.
@@4TH4RV That's nonsense. You are wrong. In reality, our sun can never ever become a black hole. It is too small of a star to ever become a black hole. After sun runs out of energy and explode due to gravity, it will become a white dwarf, not a black hole.
And Wesley is correct. With enough gravity, any matter can become a black hole regardless of its mass. If the sun were to magically gain enough gravity (i.e gravity of star R136a1), its matter will get squeeze into really tiny space and form a black hole.
Black holes are formed due to gravity. Gravity so strong that even light can't escape it. If a coin somehow gets enough gravitational force, it will form a black hole.
@@wesleyteh1901 Even if the sun became a black hole (hypothetically) gravity does not increase. The gravity becomes concentrated at the center of a black hole.

I love these videos! I loved the reminder of the hologram part. I've seen it in documentaries before and it aligns really well with the whole spiritual concept of how existence and conciousness works. The pictures are very similar and I love how old intuition based observations start to get more and more reflected in science.
The only alignment is the spelling..hologram vs holistic
Love how even the child explanation is not infantilism. Both the astrophysicist and the child have a respectful and mutual participation. There's no unnecessary giggling or filler questions like "Aww what's your favourite planet?" Kids are smarter than you think.
LMAO tell that to schools.
Yeah, I felt those vibes as a kid, like "why dont you just explain it to me, I'll get it" to my siblings in highschool 😂
I hated that, as a kid I always was smarter then the rest of my peers and got hyper-fixated on something so talking to adult was always difficult because I wanted to talk to them like an adult but they’d always talk to me as a child. My dad was the only person who really talked to me like an adult.
@@yeontan6745 wow, thd same thing happened to me, always these weird inputs which interrupt the whole discussion. i never had someone to take me as an adult when i was i child.
