Level 7 , gravity explains itself to the astrophysicist
you just described the plot of interstellar
I need to point out that I was the 666th like
im not sure you know how deep this is.
actually gravity is laughing at what humans know about gravity!!
That'd be a perfect 5/7 explanation score.
Little kid: gravity is easy
Full PhD professor: we know nothing
😂
@strafe the less you know, the less you don't know what you don't know. which is fine if you're willing to acknowledge that other ppl may know the things you don't know... and then there's the dunning-kruger effect.
Perfect example of Dunning Kruger
@testing nah gravity is just donut earth moving upwards dont trust your uncle hes wrong
This kid is smarter then many flat earther
"That's such a good question!" is my favorite response to anything I've ever heard. She sounded so genuine, like she just wants to pass along the knowledge and not be superior about it. That's my ideal teacher, wish there were more like her.
I relate to you 100% !!!!!!! Completely
I wish teachers actually used this sentence
Her ability to step down and competently explain the topic to a child all the way up to an expert is incredible. It's had as an expert to go back to basics and simplify. She does this incredibly.
She was incompetent tho what goes up will go down just not on earth.
@@dennisrideout5459 What?
@@amayasonubi2325 it’s a (nerdy) dad-joke
I will agree to some degree, see explanation in my posting.
She wasn't all that competent... as a tutor myself I found some of her explanations were non sequiturs or the other way around.
Level 1: What is gravity?
Level 5: Why is gravity?

Assuming aliens are smarter than us.
You and your third dimension. It's cute.
We have five.... thousand dimensions!
Level 7 - Morgan freeman explaining how he created gravity and how it works.
She’s that teacher we all want to listen to because of her passion which makes the subject more interesting

underrated comment
HAHAH
so true
Oh I see you've met my professors.
you're cute
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.
I concur. Poor choice of 7 year olds, she was anything but average.
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.
@@hayleygun it's a theory, not proven yet.
@@owenwaldo ........ it seems like you either completely ignored what I said or you're fundamentally misunderstanding something. Maybe it's best you do your own research on scientific theory and the forces of nature
They should've had 6 levels for this video, which goes Flat Earther, Child, Teen, College Student, Graduate, and Expert.

Astrophysicist: You're a little taller in the morning than in the evening.
8-year-old: Whoa
Me: Whoa
Cuz its the water content in the intervertebral discs of ur spine that makes u taller in the morning. Throughout the day u loose water in those discs so u are 1.5cm (on an average) shorter than the morning.
Me, a medical student: Whoa

@UC2crQiIKa8Ku44TfYmqNdNg Hhhhh I know, but you know something, especially in the field of medicine, sometimes you don't need to face the information for the first time to be caught by the beauty of it, sometimes it is exciting every single time you come across it.
I always wonder of how beautifully our bodies are working, especially on the molecular levels, you realize that we are a very complicated biochemical formula that is functioning purposefully, which is just thought-provoking, even if you already know that.
@@Mohtellawi well said👏👏
As an astrophysics student in college right now, this was both enlightening and honestly kind of inspiring and exciting to realize that I get to study all of these amazingly mind-boggling ideas everyday
I love that kid, she has supportive parents who did the experiment with her 💕 Clearly she's being raised in a curious question-asking environment!
The last interview looked like they were flirting in physics
I was thinking the same hahaha
haha same
I have totally had those conversations with physics fangirls.
They look like they are totally vibing off each other LOL!
@@jamesearley8212 the best kind of flirting
Beginner level: So this is what gravity is...
Expert level: There is no such thing as gravity
within a quantum value in a model .
Nothing is created, nothing is destroyed...there was the big bang!
@@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
Gravity is relative. Just like velocity.
That's why.
@@JavenarchX big bang is just a theory, noone can say for a certain if it happend or not.
I always liked the simple explanation of an orbit as "falling sideways fast enough that you miss the ground"
"this isn't flying... this is falling... with style..."
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.
I had that exact same thought!
When you learn something during the child’s gravity lesson
Great, you just learned a lot of nonsense.

This is the best comment on this video lol
That high school student had the exact initial explanation of gravity that the 5 year old had.
Yes, right? Wonder what that means about how high-school is teaching kids these days?
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.
@@jumpingsloth3963 found the phd physicist
The 5 year old gave a pretty good explanation also
actually, the high school student was the most accurate of them all. Prettier too
This video had me realize that I'm not nearly as hopeless with physics as I was told by my physics teacher back in school. He was simply terrible at breaking down information. If I had that woman as a teacher 16 years ago I might've ended up studying at an university instead of flunking out of my physics class because my teacher was more interested in getting evidence photos of students sneaking off to smoke rather than actually teaching.
He was just sitting on the event horizon and spewing information in several directions and not enough flew your way.
This is a perfect example of "the more you learn about something the more you understand that you don't understand 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 expert was really good; he should put out scientific vlogs! But I have always loved science, even retired now at age 73.
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.

This is really fantastic. We would love to see more of Janna Levin sharing with us more of Astrophysics. Really wonderful. Thanks for Sharing!
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!
When they got to the expert, those two looked like two science nerds who were so excited to see each other
because they were :P
Nerdgasm

Gravity was not the only thing pulling down that night
@olivia jennings I love your profile pic! Bucky is bae💕
Expert talking to 8yr: Yes honey gravity pulls you down.
Expert talking to Expert: Yeah, no there is no gravity, we just call it that.
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.
"at this height (40 km)? You dont see the curvature of the earth"

bilu the moon won’t be gone before the sun overtakes our orbit. We are talking billions, not millions.
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.
This woman is amazing! I could listen to her explaining things for hours! She has also been a guest on Startalk! I'm glad she's spreading her knowledge in an easy to understand way accessible for everyone 😊☀️
there is no [easy to understand way accessible for everyone] 😮💨😩

I like how the girl at the beginning is so composed and mature in the official interview and then we see a side clip of her screaming at being measured an inch taller LOL
You can see the joy of learning in REAL TIME, it's wonderful!

@@tiffany.pixelberry I love you for that refrence
The weird part is, I lost it somewhat with the relative speeds and seemingly being motionless at the college level and regained it at the phd and expert level. I'm a layman btw who was absolutely abysmal at physics in high school, but has watched tons of documentaries on this. I suppose that I have a weak spot haha. Must be a misplaced elektron.
I love how the last two levels felt like equals talking about all the stuff they still don't know.
"Do you know how tall you are?"
"I'm in the fours."
I believe that may be the cutest and most endearing thing she could have possibly said in response.
Taller than 3'11 but shorter than 5'
Maybe I've become an old man but I love when they feature kids that are clearly smart and curious on shows like this. It makes me feel like maybe we're not all doomed after all.

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

@@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.
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 🔥
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
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 :^)

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.
janna is an awesome teacher and when talking to "level 5" holds her own. The No 5 guy has respect for her too and it shows. He is in love with physics at the highest level and doesnt flinch much. I'd love to see an outtake where shes says " fancy a drink" and without blinking says yes !
that little 8-year-old girl was so engaged and in tune with the information given to her, her parents should be proud
She really understood everything. It was great to watch 😊
Indoctrination much.
it's scripted
I love that she conducted the experiment to see if she was taller in the morning!
She seems like a dream student.
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.

AND this is the reason why I'm choosing med school lmaoo
Why?
@@kiwibean6 Your name and pfp makes you seem like a kid so I doubt you understand it any better. Also, your asking "why?", that's such a weird question to this comment. Lol
@@kiwibean6 why not?
Level 5 : Here is a tutorial of how to flirt in physics.
Same that I thought. There was a lot of chemistry in that conversation... And they seem a bit nervous. It looked like flirting definitely.
Pretty sure it wasn't chemistry
Twas physics
It scares me how hes looking in her eyes for the entire time
@@alejandrogonzaleznevado1672 She touched up her lipstick too. I saw the brighter color and had to scroll down to the comments to see if anyone said anything about it.
This is what I call great teaching skills. Thanks for sharing this Dr Janna Levin
I just had a thought while listening to this video. We know when a mass object falls into a black hole it gets stretched. Because the mass is falling towards the singularity, it can be said that the object would continuously stretch to an infinite length. No doubt when the object gets stretch to a certain length it will break. What happens to a particle when it gets stretched so much that it's strong forces can no longer hold it together?
I swear the last 2 were just flirting in physics talk
It was a dream to watch
I'm surprised I had to scroll so far to see this-I instantly picked up that vibe when I saw how he was sitting, haha. That intellectual chemistry is a life goal.
Just look at the last guy staring at her...
YES! THANK YOU! It was immediately obvious! Lmao!
i think she might've been uncomfortable with his glaring tho....
That girl at the beginning is such a delight. She is very smart and composed. Lot to be proud of there!
She literally knew more than a teen who is studying physics.
Doubt it
@@Max-xt1fo You "literally" don't know what either of those people know.
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.
future scientist right there
When mentioning the square inverse law it sounds more like atmospheric pressure. For the effects vary due to matters relation to a solistrial body. The force/pressure isnt a pull in relation to the source but is being acted upon in all directions (to include internally). ie. An inflated sphere.
I had the pleasure to see Janna Levin present as a guest speaker at Winton Capital in London. She was part of those gravity wave detection experiments she talks about in this video. It was a fantastic experience and to see how humble yet engaging she can be both in person and in this video!
The expert has no light behind his eyes, only math. I love it
Its good he is a physicist because he has the stare of a serial killer.
Why do y'all say he like.. isn't the expert a 'she' here?
Oh lmfao I'm so sorry, I didn't watch it till the end and thought the astrophysicist was considered an expert
@@acedcoffee6934 You are also right. The woman who was the moderator is a PHD in astrophysics .
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.
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.
Thank you for this insightful video. I appreciate how well each person communicates their understanding and perspective. Also, I'm all about those nerd jokes near the end.
the constant nodding and vocal agreement of the college student made me uncomfortable🤣🤣🤣 was she really understanding? lol
Could you get a chemist/ physicist to explain entropy on 5 levels?
I second this!
How bout you just... I dunno, read?
@@user-cq8tt5ek3x
So you don't like these videos?
Yess!!!!
I 3rd this
That lil girl is learning well in her science classes.
@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.
I took up following astrophysics youtube channels and watching lectures a couple of years ago; what a gift!!!!!
I've always thought about gravity because for me gravity is very painful and never ending. I've had a birth defect in my spine that's caused constant pain since 1979. The best relief I've found was in the 90s when I got one of those inversion tables where you hang upside down by your ankles. I don't have to get completely upside down. Anything past parallel to the floor takes away the gravity pushing down on the base of my spine. It's also about the only way I can sleep, but I have to set an alarm for just a few minutes or all the blood runs to my head.
Astrophysicist: What did you learn today?
Me: I learned that I am as intelligent as a child... 🤔
EZ fix...read a book. All the info up until the expert is learned knowledge. During the expert portion they discussed theory.
Same
7:24 asked my University physics teacher the same question, she couldn't answer the question. We need more teachers like this astrophysicist*, make it interesting and fun to learn and explore the environment we live in :)
Intelligence as a measure actually doesnt vary that much between childhood and adulthood ;)
Mike Hoang I feel that😂
I like she used words like “epiphany” while talking to the little girl. Using words like that in context teaches its meaning really effectively. IMHO.
my mum always used 'big words' when talking to me, even when I was really little. It helps a lot.
I feel like the term went over the kid's head
@@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.
Kije Kuyo
Exactly! And thank you for putting it so well!
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.
Great descriptions. My favorite part was that I was able to follow it all.
This is gold. I love what this channel does. THANK YOU
god bless. have a great day my nikka❤luv man
Lil girl: "Just like the tides?"
Astrophysicist: STAY IN YOUR LANE!
Instant vibe check
Genius kid spotted
@@kevinree6461 script spotted
Kevin Ree I knew that too when I was her age, you don’t have to be a genius for someone to tell you about that at that age
CookieCakeEater yeeup, you can find CZcams videos everywhere on it.
