Throughout everything I've watched with Neil, every time Neil hits Chuck in the arm or anyone else, it means he's about to blow your mind with a scientific fact. It's like a 'shut up, immabout to educate you' hit. Not mad at it at all.
Two things...first, I love how Neil can be so intelligent and in a blink can come down and enjoy humor that most of us share. Second, I had always thought that the sky was blue because sunlight was being reflected off our oceans into the atmosphere. Makes me start rethinking what else I have so drastically misunderstood.
I hated school growing up most of all I hated science but the way you teach is amazing I'm completely interested in all things space and stars. Keep it up.
The way he explains this doesn’t make sense for the earth 🌎 to be blue from outer space. Water is clear, and most swimming pools are blue inside. The paint 🎨 color inside a pool, makes the water seem like it’s that color.
me too - however, i only hated science at that point, because it could not answer the things i wanted in sufficient depth to fully grasp and understand the universe we live in - now however, i envy those going to school, as the amount of knowledge gathered since i was in school, is mind blogging. and in case i am 38, so was a long time ago. hence, science can now answer to the degree of understanding i want/need. Biggest issue i had in school, was the way it was taught, never taught to understand, just taught things to repeat, so i would sit there and say how is that, how does that happen, why does that happen, and as you can guess couldn't get an answer, so lost interest in it. And at risk of repeating, now they can fill in those blanks and explain things fully, like evolution, and my passion for learning is re-ignited.
Thanks for this! I'm a science teacher and had the privilege of naming our first-born daughter, Rayleigh. She's heard me say several times that I'm reminded of her whenever I look up at our beautiful blue skies and our equally majestic sunrises and sunsets. She now has a much better understanding and appreciation for why that is.
I love how people often ask "why is the sky blue" in response to a question they don't know the answer to - as if it's some unanswerable question. Now when someone says that we can be like "Bam! Science!"
Science has never been this fun. Wow! I wish I had such fun and great teachers during my school years. I flunked Physics/Science and literally had anxiety when I had class. I'm relearning everything anew. Thank you so much for this channel 🙏
It really does come down to having fun. As a kids (9 years old and younger), school was fun. As I got older, it seemed like a job I wanted to quit from.
It is actually fun because we can relate easily to it. The problem is that we have teachers who spend quality time discussing unions issues and never teach learners properly.
I could sit and listen to Neil for hours on end. I love science, particularly his field of science and, I wanted to study physics in college but I couldn’t do the math.

It's the opposite. It's clear and it's reflected by the sky.

i remember asking my teacher in elementary about that and all she said was its a reflection of the ocean. and i went with that through adulthood. public school system failed me.
@@jdnoflegend9719 That’s actually not why the ocean looks blue either... Water is just blue! It doesn’t reflect that much blue light, so that’s why you can’t tell when it’s in a cup, or in your bath tub. But you can tell when it’s deep in an ocean, or a lake 😁 It’s kind of like how he just assumed you couldn’t see the stars because the sun is bright. We would think that’s the answer, but it’s not!
Although I'm a scientifically literate person and happen to have already understood the answer to why the sky is blue, I still click on these videos with Neil because of his excellent use of words and clarity in explaining
Tell me if you say that the sky is not a fixed boundary but gradually transition into space,does that mean while there's no physical boundary, there are practical limits?
I love listening to this man explain things. It's always from a point joy and amazement that he teaches. It's very refreshing to see someone who makes you wanna learn and genuine enjoys it.
I had a question...we know that during day sky is blue due to scattering of blue light of visible spectrum. During sunsets the sky looks reddish as most of blue light is scattered as the rays have to cover longer distance...so isn't there a contradiction that during day it looks blue and during evening it looks red both of which are due to scattering of blue light ?? I mean how could it be that we have to different outcomes due to the same phenomenon?
I got a question : During the evening the light from the sun has to travel more thus more scattering and no blue light left so it appears red. But why is the sky red near the sun, but just above me it's still deep blue. I noticed this yesterday. The blue sky above me is farther than the red sky at the horizon where the sun is setting.
This is my favorite channel now, I'm not sure why TH-cam didn't recommend this to me sooner but I'm loving this channel. He explains everything so well and easy to understand. They definitely should be teaching all this in school.
I went to like this video once finished, but I already liked it probably 2 years ago! Great content! Also great to refresh simple but incredibly ignored concepts ! Thank you to both of you
P. A. Well said. I really think Black American’s think they have it bad. It’s literally built into India’s social system. I’m sure you know more than I do, but I totally agree.
Likely the air conditioning is turned down to about 62°F, and if you're skinny, you feel the cold more intensely. That's my hypothesis, anyway. Since NDT is wearing a long sleeved shirt of some type under a short sleeved shirt, so he has at least 2 layers on, himself. Maybe a 3rd, if he has an undershirt on, too.
I kind of get the concept of why people say I’m feeling blue The bigger the stronger and the more pressurized a blue atmosphere The more blue it is but the lighter the atmosphere is the lesser blue it is so I think the ssying I feel blue is to let people know you feel pressurized
So if a candle is lit at the bottom of a football stadium in broad daylight and you can't see it, but it is visible at night, that is due to light from the sun scattering it rather than your rods being too saturated with light to differentiate it? If light from the sun scattering through the atmosphere obscures stars during the day, can't this also be explained in terms of your rods being too saturated with light? If no detector would be able to differentiate such a low light source in areas of high saturation, how can we be sure whether the explanation is relative intensity vs scattering?
In the fifth grade, I remember our teacher giving us a question that read, "What color is the sky?" I was a super nerd and loved reading. So, by the time I was in 4th grade, I was reading encyclopedias for fun, learning tidbits that I wouldn't really come across until HS. To shorten this story, I explained in detail similar to how Dr. Tyson described it about how the light from the Sun scatters in our atmosphere and the color that is reflected is what we see (much like how grass absorbs all the other colors that make up light and reflects green). Well, my teacher straight up gave me an F for the assignment!! 😡 I was so crushed because I knew I was right and when I went to talk to her about it, she just brushed it off. This was over 20 years ago, but it's great seeing videos like this on TH-cam! Bill Nye, The Magic School Bus, Reading Rainbow, etc were among my favorite shows as a kid!! 😃
Chuck Nice never misses an opportunity to remind everyone he loves in America. But Neil is the unbelievably informative and entertaining. The difference between someone like Neil who thinks large and looks up and everyone else.
I was always told the opposite, the the ocean is blue because it's reflecting the blue sky. Which is why water, whether in a cup from your sink or a cup of ocean salt water, is not blue.
No, it isn't scattering from particles about the same wavelength as the blue light. It is mostly from air molecules, not particulates, and air molecules are a LOT smaller than the wavelength. Rayleigh scattering is from particles much smaller than the wavelength, including molecules. The Rayleigh scattering goes as the inverse fourth power of the wavelength, which is why blue light is scattered much more than red.
Neil, you said that particulates scatter the blue color, but only some, not all, leaving some blue coming through, so the shy looks light blue, and gets more orange and red at sunset as there is more scattering of the blue. How is it that the others colors dont get scattered at any time?
Tysons answer was almost true but not completely. The particle size does not match the blue light. The scattering happens more when the wavelenght of light is smaller. And to the power of 4. Indeed violet light is scattered more than blue. But there is so little violet in sun light the sky is seen blue.
How will you get teachers like him when there is a war on teaching facts or anything Science. I can’t think of a time in our history where Science has been considered not essential, political and a conspiracy. Scientific Theorems, Laws and known truths that have been around for decades are now fake news according to someone on Facebook, Twitter, TickTock, etc. Everyone is an expert now in field of Science and supposedly we have alternative facts. Yes you heard that right. Alternative facts said a former presidential spokesperson with a straight face. Books banned, Classes need approval personally by a governor with zero formal training in education. Neil D Tyson and people like him are rarely valued.
Actually he has done that many times. And thats the beauty of a proper educated person: strong enough to answer vast numbers of questions smoothly, but humble enough to know his limitation of his knowledge and acknowledge that.
I didn’t understand why there’s less atmosphere to go through during the daylight than in let’s say the twilight. Can someone please explain? He says it at 4:55 ish
It's the angle at which the sun's light is reaching you. From directly above, the light passes through a lesser distance to travel through the atmosphere than it does when the sun is low in the sky. 🙂
Isn’t it Mie Scattering when the particle is at the same size as the wavelenght of light, and Rayleigh Scattering when the particle is much smaller than the light? Please explain someone.
What a great, holistic explanation! Seriously. But I was wondering, if our atmosphere and particles or air molecules in them are really so much responsible for the blue or red light that we see everyday, then global warming and all the collective pollution that we are creating here on earth, which is definitely affecting our atmosphere in an adverse way, will that ultimately lead to changing of the sky colours in the future at some point? Because definitely the density of the air molecules will change due to pollution and it's disastrous effects. Won't that affect the colours in the sky too?
Neil actually cures my depression

I got a question :
During the evening the light from the sun has to travel more thus more scattering and no blue light left so it appears red.
But why is the sky red near the sun, but just above me it's still deep blue. I noticed this yesterday.
The blue sky above me is farther than the red sky at the horizon where the sun is setting.
The way Neil is so vibrant and happy when he talks about atmospheric science is so awesome and wholesome

I literally asked my dad why the sky’s blue and he picked up my phone and put this on.
your dad is awesome lol
Best dad
Clever dad ...
Best dad in the world!
Foolish dad ever.
I can attend his classes all day long 😀 he is my hero since my childhood
This is my favorite channel now, I'm not sure why TH-cam didn't recommend this to me sooner but I'm loving this channel. He explains everything so well and easy to understand. They definitely should be teaching all this in school.
I love to listen Neil. He explains everything so well. He is a great teacher. 🙂

It was hard to make up that lie.
@@dantejuantrelgeorge4126 hard to hide that fading hairline
Neil is a great liar 🤥. The sky is blue because it’s water. Next question.
@@Truthisstrangerthanfiction8you know that water is not blue right?? It seems blue for the exact same reason why the air seems blue.
Would love to see Neil debate a flat earther 😂
Wouldn't be fair. A flat earther ALWAYS brings a knife to a gunfight.
me too! he would get destroyed
@@NinjaGaiden-z7t The flat earther or Neil?
@@riasasselman4528 the flat earther with evidence, neil for stooping to have that conversation.
@piet simons how can you explain that even the bible says that the heaven expands? Like our universe :)
I can't wait for a kid to ask me why the sky is blue! I'mma be like: YES!!! I know the answer!
Me2
KXNG DAVID yup. Ima be waiting for the day someone asks or says why the sky is blue
Let’s here the answers why is the sky blue? And go!
Lol, u ain’t explaining all this
and he'll be sorry for asking
I went to like this video once finished, but I already liked it probably 2 years ago! Great content! Also great to refresh simple but incredibly ignored concepts ! Thank you to both of you
Why is everything racist to you..."cause I live in America" 😂😂😂
Musaasizi Joshua yo i died i wasn’t expecting that
@Sumo Banger To paraphrase Red Skull: "Racism may not be a uniquely American trait, but I must say you do it better than anyone."
P. A. Well said. I really think Black American’s think they have it bad. It’s literally built into India’s social system. I’m sure you know more than I do, but I totally agree.
I was just about to comment that hahahaha 🤣🤣
Being an American astronomer has got to be really hard with all the white suns, black holes, red giants and yellow dwarfs.
That man is wearing:
1. A dress shirt
2. A sweater
3. A suit jacket
The question of this episode should have been "Why arent you dying?"
Are you a woman? Scientifically and curiously asking...as I am a man and unti l read your comment I had no idea what either of them wearing.
It's a...
Shirt and tie
A possible hoodie?!
And a Jacket!
Looking at him..... there may even be a vest :P
But the question is no less valid!
Sooo???
Dress shirt, hoodie (are you kidding me?!?), and suit jacket? What is wrong with this guy?!?
Likely the air conditioning is turned down to about 62°F, and if you're skinny, you feel the cold more intensely. That's my hypothesis, anyway. Since NDT is wearing a long sleeved shirt of some type under a short sleeved shirt, so he has at least 2 layers on, himself. Maybe a 3rd, if he has an undershirt on, too.
I wish this is what science class was in school.
Sooooooooo true
I kind of get the concept of why people say I’m feeling blue The bigger the stronger and the more pressurized a blue atmosphere The more blue it is but the lighter the atmosphere is the lesser blue it is so I think the ssying I feel blue is to let people know you feel pressurized
That’s impressive Neil, but can you explain why my dad hasn’t come back with his milk yet?
Oh Shoot!😂 Maybe he s in the atmosphere.
💀
Because he is finding you a new, hotter and younger mummy..
He never left... But the particles are preventing you from seeing him
"Daddy wasn't there, to take me to the fair."
I still love the Dad joke with this one. :"Daddy why is the sky blue? Because if it was green you wouldn't know where to stop mowing. "
I will remember this and use it on my future kid
Lol.
Mowing to the horizon? :P
Was the yard was uphill
Neil: "White light comes down from the sun."
*intense hand gestures casting a spell on the globe*
The sky’s blue is the light bouncing off & through the earth. A beautiful glow.
One of the finest explainatons of a "technical subject" in "non-technical language".
Three eighths of an inch. What I want to know is when is the USA going to start using metric?!
It is used in some areas. Neil doesn't like the metric system though.
@@jefflane8272 he does like it and he prefers the metric system.... im pretty sure 99.9999% of scientist do
The answer is: NEVER
randall davis ,and Thats Sad.When Its Used Everywhere Else
used millimeters in the end anyways
Was anyone else told the “sky is blue because it’s reflecting off of the ocean”
its the other way!
I was.... hahaha
My teacher told me that
Riiiiggt
thats when you ask "then why is the ocean blue?"
"If we didn't need atmosphere, I would want to get rid of it" These guys are the best!! Thanks.
I really love how easily he can put things, that would otherwise be complicated, into a perspective that we can all understand.
Sign of true comprehension
7:30 I laughed so hard when Neil smacks Chuck twice then he stops talking after the second smack😂
Even i was thinking that. He keeps hitting the guy. I was feeling them.
1:38 GOOOOOLD GOOOLD GOLD 🔥⚡
1:57
11:55
12:22 and OF COURSE 🔥🔥🔥
So if a candle is lit at the bottom of a football stadium in broad daylight and you can't see it, but it is visible at night, that is due to light from the sun scattering it rather than your rods being too saturated with light to differentiate it?
If light from the sun scattering through the atmosphere obscures stars during the day, can't this also be explained in terms of your rods being too saturated with light? If no detector would be able to differentiate such a low light source in areas of high saturation, how can we be sure whether the explanation is relative intensity vs scattering?
"because if it were green, we wouldn't know where to stop mowing!" - Judge Harry, Night Court
I’ve definitely learned more from Neils books shows and podcasts than my actual science teachers .
I hope you know there are many different types of scientists right I doubt your teacher they planetary scientist
"Why is everything racist with you?"
"because I live in America"
😂😂😂
maybe because all he sees is race.
Best Moment lol
@@ChickenPermissionOG Indy 500, F1 you name it. He sees all the races!
Neil rocks! I always enjoy and learn something new listening to him.
In the fifth grade, I remember our teacher giving us a question that read, "What color is the sky?"
I was a super nerd and loved reading. So, by the time I was in 4th grade, I was reading encyclopedias for fun, learning tidbits that I wouldn't really come across until HS.
To shorten this story, I explained in detail similar to how Dr. Tyson described it about how the light from the Sun scatters in our atmosphere and the color that is reflected is what we see (much like how grass absorbs all the other colors that make up light and reflects green).
Well, my teacher straight up gave me an F for the assignment!! 😡 I was so crushed because I knew I was right and when I went to talk to her about it, she just brushed it off. This was over 20 years ago, but it's great seeing videos like this on TH-cam! Bill Nye, The Magic School Bus, Reading Rainbow, etc were among my favorite shows as a kid!! 😃
Not surprising considering haw poor the curriculum is for teachers is ,AND then there is the schoolboards incompetence.
It sucks to have a teacher like that bro
I read encyclopedias, too, but science wasn't interesting to me then. It definitely is now.
I'm glad you didn't let her deter your love of learning.
So what was her (faulty?) explanation? Do you remember?
Neil De Grasse: Says science things
Chuck: N I C E
11:59 think Neil is trying to tell Chuck that it’s time to take their conversation to the court! 🏀
lol, drop the last "the" and that sentence get a much darker meaning :))
I love Neil so much. Troughout why whole childhood I've never had teacher with such a patience, passion and flow in explaining.
How can you not love how wholesome these two are with each other XD
Chuck Nice never misses an opportunity to remind everyone he loves in America. But Neil is the unbelievably informative and entertaining. The difference between someone like Neil who thinks large and looks up and everyone else.
This quarantine has me deep into youtube deeper then ever
honestly this aint that deep
M00N deep

Gábor Králik no fella 😂
already went to the bottom and now working my way back up
My child talks about science with the same amount of passion and wonder. ❤️
Can’t believe school taught me it was the reflection from the ocean.
Yes that was my original taught
In school they taught us the opposite actually... That is why the ocean is blue
All teachers should be scientifically fluent, for that reason.
I was always told the opposite, the the ocean is blue because it's reflecting the blue sky. Which is why water, whether in a cup from your sink or a cup of ocean salt water, is not blue.
The Albedo effect? Isn't that a little different from this.
"Why the sky is blue?"
"We're all gonna die"
😂
JONN LLOYDE lol😂😂😂
that was a great conclusion xD
No, it isn't scattering from particles about the same wavelength as the blue light. It is mostly from air molecules, not particulates, and air molecules are a LOT smaller than the wavelength. Rayleigh scattering is from particles much smaller than the wavelength, including molecules. The Rayleigh scattering goes as the inverse fourth power of the wavelength, which is why blue light is scattered much more than red.
I like this challenge! 💯👍✅🔥🔥
Neil, you said that particulates scatter the blue color, but only some, not all, leaving some blue coming through, so the shy looks light blue, and gets more orange and red at sunset as there is more scattering of the blue. How is it that the others colors dont get scattered at any time?
I love when educators / professors / teachers / instructors make the content fun and engaging!
I knew the answer to this before I clicked on the video...I'm not sure why...I love this child-like question answered so scientifically simplistic
Tysons answer was almost true but not completely. The particle size does not match the blue light. The scattering happens more when the wavelenght of light is smaller. And to the power of 4. Indeed violet light is scattered more than blue. But there is so little violet in sun light the sky is seen blue.
same here, I just wanted to see some jokes from Chuck actually
I had an answer, but that answer was given to me in school and it never convinced me. Now I know why. It is because it wasn't the right answer.
I LOVE your show!!!I hope I can meet you some day. I've loved science from a very young age. Thanks for doing amazing things!
I want to meet him, because I've got some questions.
Here is the cosmos fan club
I find it beautifully poetic that the guy who discovered how sunlight scatters is named RAY-leigh
Neil just casually throwing the Earth from hand to hand is just what I wanted to see, thank you
If we had teachers like these, science would have been very interesting
How will you get teachers like him when there is a war on teaching facts or anything Science. I can’t think of a time in our history where Science has been considered not essential, political and a conspiracy. Scientific Theorems, Laws and known truths that have been around for decades are now fake news according to someone on Facebook, Twitter, TickTock, etc. Everyone is an expert now in field of Science and supposedly we have alternative facts. Yes you heard that right. Alternative facts said a former presidential spokesperson with a straight face. Books banned, Classes need approval personally by a governor with zero formal training in education. Neil D Tyson and people like him are rarely valued.
I am so glad they didn't cut out the comedy. It's priceless.
3 words Neil has never uttered: "I don't know".
I would debate that - the reason he knows so much is that he’s curious about what he doesn’t know and researches.
Actually he has done that many times. And thats the beauty of a proper educated person: strong enough to answer vast numbers of questions smoothly, but humble enough to know his limitation of his knowledge and acknowledge that.
Actually he has when asked what is gravity
@@patsmith2505 JRE 🤣🤣
@@markgeorges7645 Dont get ahead of urself I know he knows what hes talking about......Hes just an actor to me and many others 😉
What an awesome human being he is ❤️
I just love how expressive he is when explaining things. 😂
I didn’t understand why there’s less atmosphere to go through during the daylight than in let’s say the twilight.
Can someone please explain? He says it at 4:55 ish
It's the angle at which the sun's light is reaching you. From directly above, the light passes through a lesser distance to travel through the atmosphere than it does when the sun is low in the sky. 🙂
Isn’t it Mie Scattering when the particle is at the same size as the wavelenght of light, and Rayleigh Scattering when the particle is much smaller than the light? Please explain someone.
These explanations made my mood better. The method of explaining filled me with curiosity and deep happiness. Thank you so much💙
This is interesting. I learned a lot here. I also thought it was the sun outshining stars as to why you cant see them in daylight.
The atmosphere apple skin length part at the end blew my mind
The whole video is explained in less than a minute timestamp: 12:23
I asked once, they were like, "Mind your business"
100% can relate
No one said ever
Sure
When there's passion into something you get people like them that make these stuff super interesting to talk about.
Absolutely. Learning is life
What a great, holistic explanation! Seriously.
But I was wondering, if our atmosphere and particles or air molecules in them are really so much responsible for the blue or red light that we see everyday, then global warming and all the collective pollution that we are creating here on earth, which is definitely affecting our atmosphere in an adverse way, will that ultimately lead to changing of the sky colours in the future at some point?
Because definitely the density of the air molecules will change due to pollution and it's disastrous effects. Won't that affect the colours in the sky too?
The best “insult” ever: you’re such an astrophysicist 😂❤️
