She used it correctly. A hypothesis is made before any data has been gathered. What Dr. Moo referenced is a theory because it’s based on existing evidence about what we know about how yawning affects the body. Laypeople don’t know that a theory and a hypothesis are two different things. Arrogant laypeople (like the guys lecturing a NASA scientist about terminology) don’t know that it’s even more complicated than “they are two different things.”
@@Antenox "A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment. In circumstances not amenable to experimental testing, theories are evaluated through principles of abductive reasoning. Established scientific theories have withstood rigorous scrutiny and embody scientific knowledge"
@@KubaR0506 Note the terminology: "ESTABLISHED scientific theories have withstood rigorous scrutiny." That means there are theories that are NOT established. And the theory Dr. Moo cited is exactly that type of theory. Here is the distinction between a theory and a hypothesis: - Theory: "Yawnings might happen because the body wants to increase heart rate and oxygen in the blood" - Hypothesis: "IF this theory is correct, THEN heart rate and oxygen will increase when you yawn. True or false? Let's test." What Dr. Moo cited IS indeed a theory. The only thing that is required for a theory to be a theory is that it is an explanation that is consistent with data that has already been gathered in past studies/experiments/etc. Theories that are "just theories" are theories that aren't yet strongly supported with evidence, but which still provide an explanation of the mechanisms. But that still makes them distinct from hypotheses, which are predictions of outcomes based on the mechanism supplied by the theory.
Having someone actually talking the lines instead of making us just read it with BLARING MUSIC going on is a huge improvement. Thank you. I look forward to more like this.
My theory: Its your body trying to move, stretch and be more active when you aren't being active enough to justify being awake. That's why you yawn at meetings, school or when you're watching a boring movie. Also when you are getting ready to go to bed but you have other things to do first. You typically stretch when you yawn. You stretch a lot of muscles not just in your face, but the rest of your body as well (arms, back and even legs and feet). It's your body trying to move and stretch and perhaps even breathe more when you are being stagnant but resisting the urge to sleep.
A fetus also yawns while still in the womb so that seems to undercut the idea that it has to to with oxygen levels or brain temperature. If it had to do with temperature one would also expect yawning to be more prevalent in warmer regions.
@@MorgothBauglir13579 There is no air inside the womb, (oxygen is supplied by the mother through the umbilical cord) therefore air-cooling the brain through yawning is not possible.
What a load of crap, I have empathy towards everyone I met and seen them yawn many of times but It don't always make you yawn. This video shouldn't exist except for the first two parts. We still don't know why we yawn but you can’t blatantly call everyone a likely psychopath or unempathetic just ’cause we don't yawn when seeing/hearing it. That is so wrong.
Shouldn't say "just a theory". Call it a hypothesis, instead. Saying it's just a theory confuses people into thinking other theories are just guesses instead of the immensely studied and peer reviewed subject matter that they are.

I was looking up this specific reason and happened to find you covering over the facts n stuff,immediately clicked because you make learning fun and entertaining
You don't get a large amount of gas exchange to replace O2. When you yawn you stretch the muscles in the throat which causes the one side of your sinuses to drain. Several times a day the brain turns this function on , were one side of your sinuses drains and the other fills up with mucus. This is done to regulate the temperature of the brain,by changing the insulating nature of the sinuses. To test this gently massage your sinuses if you hear a clicking sound you should feel mucus draining , at that point you should yawn .( clicking sound is made by air bubbles in your sinuses collapsing. The muscles stretched open the nasopharynx aperture to facilitate drainage. The reason you yawn when bored is that lactic acid is a stress and fatigue poison ,high levels of lactic acid cause the brain to over heat ,so the brain will try to cool things off using the above technique. If you don't believe me ask a sinus sufferer.
"The reason why a yawn is contagious is because of empathy" makes no sense to me, because then shouldn't we mimick every other move someone does because of empathy? We do that only for yawns so there must be a reason that holds its own
Alexandre Géhin> We do that only for yawns so there must be a reason that holds its own Not really, we tend to laugh when we see someone laughing, we feel sad when we see someone cry, we tense up when we see someone looking scared, we get alert when we see someone angry.
I thought the leading hypothesis on the reason for yawning was temperature control, and based on that then the reason yawning is contagious is "if I'm near them and their brain is too hot then my brain must be too hot."
i've always heard it was our circadian rhythms, this way as a populace of nomadic peoples we would all be on the same timeline of sleep and wake. but then again, I'm a boomer so what do i know
It was poorly stated. Many animals are social, but humans are INCREDIBLY social. One of the reasons is biomechanical perception; when we see a person do something, the neurons we would use to do the same thing fire very faintly. They fire nowhere near enough to cause us to do the same thing, but we have a very direct and intuitive perception of other humans' states. This mirroring of neuronal states, as well as the vast number of neurons dedicated to facial expression and our preoccupation with sight, enable us to be intensely social. So much so that we respond very well to symmetry and not well to asymmetry. If you duplicate someone's stance, pose and mode of expression they will tend to enjoy your company more, and the opposite for the opposite. It could be that whatever autonomic system that yawning is wired to is on a hair trigger and just the smallest tickle of seeing someone else yawn (or imagining it) is enough to set it off.

What the hell has happened to this channel lately? Even Thor acts like he doesn't give a fuck anymore.
Lol.... mate. He doesn't. He left like three weeks ago. Search "Kyle Hill" on TH-cam, you'll find his new channel. Maybe if they paid him, he'd still be here.
I see you finally got a voice that's nice. Just a little note the background music is a little bit overpowering drowning out at times the person's voice.
This is why stupid people think the earth is flat and evolution isn't real. F***, I didn't think losing Kyle would COMPLETELY tank the channel like this. Wonder why type of "doctor" she's pretending to be.
@@iami3rian394 Her doctorate is in mechanical engineering. There's no excuse for attacking her just because you were told something in grade school science class that she's not following.
@@MorgothBauglir13579 Except it's not. Scientific "laws", "theories" and "hypothesis" are not beholden to the made up hierarchy you were told in school any more than the person you were told "discovered America" or those belt-buckle hatted pilgrims you were presented pictures of eating turkey.
@@Merennulli see except theories and hypotheses are defined by other words, which make you look like a jackass. Do you believe somehow passing from seventh grade to a doctorate changes the definition of a scientific theory, like it changes your perspective from not knowing what happened when Columbus got here? Are you dense enough to imagine a universe where numbers are subjected to the mathematicians education level? Wtf are you even trying to say, hippie?
My theory is that when we sleep we take in more oxygen and when we wake up in the morning we yawn for a kick start to the day and we yawn at night or whenever we normally go to sleep because it's our body saying ok this is our normal time to fall asleep and the empathy thing might not even be a choice for people it is most likely for us to yawn when someone else yawns because it is a instinct of some sort or a involuntary response but that's just a theory a science theory but hey what do I know I am just a kid in high school trying to graduate
I love how they only go over stuff most don't believe is why They completely skip how a lot of scientists think it could be a let over part of our body an instinct of sort like how you'll typically jump back from a snake because most believe you yawn from when humans needed a way to indicate it's time to best down for the night a wide spreading yawn as the sun gets low saying okay time to get ready to sleep
I think the way to find out why we yawn is in magic mushrooms. when I'm tripping on shrooms, every time I think it's wearing out, I yawn, and the high returns even more intense than before
I know scientists don't believe in God majorly, but could I ask you to analyse the speed of the character samson from the Bible? He managed to catch 300 foxes which can move at 50km/h in 1 hour, how fast would you have to be to manage that feat?

I don't think they prepared for kyles departure
You don't get a large amount of gas exchange to replace O2. When you yawn you stretch the muscles in the throat which causes the one side of your sinuses to drain. Several times a day the brain turns this function on , were one side of your sinuses drains and the other fills up with mucus. This is done to regulate the temperature of the brain,by changing the insulating nature of the sinuses. To test this gently massage your sinuses if you hear a clicking sound you should feel mucus draining , at that point you should yawn .( clicking sound is made by air bubbles in your sinuses collapsing. The muscles stretched open the nasopharynx aperture to facilitate drainage. The reason you yawn when bored is that lactic acid is a stress and fatigue poison ,high levels of lactic acid cause the brain to over heat ,so the brain will try to cool things off using the above technique. If you don't believe me ask a sinus sufferer.
"The reason why a yawn is contagious is because of empathy" makes no sense to me, because then shouldn't we mimick every other move someone does because of empathy? We do that only for yawns so there must be a reason that holds its own
Alexandre Géhin> We do that only for yawns so there must be a reason that holds its own
Not really, we tend to laugh when we see someone laughing, we feel sad when we see someone cry, we tense up when we see someone looking scared, we get alert when we see someone angry.
@@user-vn7ce5ig1z you both have valid points because just reading this comment made me yawn... lol
I thought the leading hypothesis on the reason for yawning was temperature control, and based on that then the reason yawning is contagious is "if I'm near them and their brain is too hot then my brain must be too hot."
i've always heard it was our circadian rhythms, this way as a populace of nomadic peoples we would all be on the same timeline of sleep and wake. but then again, I'm a boomer so what do i know
It was poorly stated. Many animals are social, but humans are INCREDIBLY social. One of the reasons is biomechanical perception; when we see a person do something, the neurons we would use to do the same thing fire very faintly. They fire nowhere near enough to cause us to do the same thing, but we have a very direct and intuitive perception of other humans' states. This mirroring of neuronal states, as well as the vast number of neurons dedicated to facial expression and our preoccupation with sight, enable us to be intensely social. So much so that we respond very well to symmetry and not well to asymmetry. If you duplicate someone's stance, pose and mode of expression they will tend to enjoy your company more, and the opposite for the opposite. It could be that whatever autonomic system that yawning is wired to is on a hair trigger and just the smallest tickle of seeing someone else yawn (or imagining it) is enough to set it off.
I yawned 3 big times during this vid
We yawn because its a stretch for jaw and throat muscles. Singers also do it and it helps with headaches and regulate ear pressure.
Where's Kyle.
He quit because they stopped paying him. Has his own channel know. Kyle hill. Find it, it's awesome.
@@iami3rian394 why would they do that ? He was basically the brand behind this change
@@chiRal123 if I could stop companies from being stupid, DC would also be owned by Disney, we'd be watching blockbuster original shows, and Burger King would be on every street corner.
"They done screwed the pooch" is about the best answer you'll get from me, unless you're floating my $300k salary. = )
In which case, after an extensive 3 year investigation, I'm stepping down as the lead on this project because I'm rich, bitch! And also, they screwed the pooch.
For current references, GameStop is presently ruining themselves rather than adapting. They could make a 2-1 conversion deal with MS and Sony for console bucks....
Then they could kiss ass, HARD and close some stores. After they took over ebgames, electronic boutique, and... uh the other one... they never shut a store down. Saturation was their plan.
Turns out, when you have $12M overhead, you need to make $12M bucks before you're profitable.
They will fail again because ceos are notoriously stupid.
The smart people get bought out by the richer smart people.
What the hell has happened to this channel lately? Even Thor acts like he doesn't give a fuck anymore.
Lol.... mate. He doesn't.
He left like three weeks ago. Search "Kyle Hill" on TH-cam, you'll find his new channel.
Maybe if they paid him, he'd still be here.
I can listen to her all day.
I see you finally got a voice that's nice. Just a little note the background music is a little bit overpowering drowning out at times the person's voice.
"However it's still just that... a theory." A hypothesis. Let's not play with "it's just a theory" nonsense terminology.
This is why stupid people think the earth is flat and evolution isn't real.
F***, I didn't think losing Kyle would COMPLETELY tank the channel like this.
Wonder why type of "doctor" she's pretending to be.
@@iami3rian394 Her doctorate is in mechanical engineering. There's no excuse for attacking her just because you were told something in grade school science class that she's not following.
@@Merennulli
Except the thing we were told in grade school is the literal, correct terminology...
@@MorgothBauglir13579 Except it's not. Scientific "laws", "theories" and "hypothesis" are not beholden to the made up hierarchy you were told in school any more than the person you were told "discovered America" or those belt-buckle hatted pilgrims you were presented pictures of eating turkey.
@@Merennulli see except theories and hypotheses are defined by other words, which make you look like a jackass.
Do you believe somehow passing from seventh grade to a doctorate changes the definition of a scientific theory, like it changes your perspective from not knowing what happened when Columbus got here?
Are you dense enough to imagine a universe where numbers are subjected to the mathematicians education level? Wtf are you even trying to say, hippie?
It's just a theory , A SCIENTIFIC THEORY !! Thanks for watching
Congratulations! You broke my favorite channel...
OK. We got a narrator. Good. Now for better material.
Get rid of the looping background music. Also if you could get her to narrate why not just shoot an episode with her? She already has in the past.
She's too busy being a "doctor."
I think it's just easier to send her script so she can read it, then bring her to studio for proper episode
I kept yawning trough the whole video, does it mean it's boring?
I yawned as soon as I read the title for this video. Why is yawning "contagious?"
It’s not the same
Am I the only one trolling Because Science for kyle
Seriously though this channel is BS without kyle😉... Get it BS=Because Science
I heard a theory that you yawn when you see other ppl yawn, you're brain sees that and thinks it might be a good time to yawn if they are
This video made me yawn 6 or 7 times. I begin to yawn if someone just talks about it.
I was half expecting her to say, "But that just a theory, a scientific theory!"
If you didn’t yawn while watching this video, I refuse to believe you exist
I guess I am a figment of your imagination then
@@minecraftmaster2215 Maybe you are an alien
@Axel Huett Maybe
@@minecraftmaster2215 I’ll take that as a yes
@Axel Huett the world may never know
I can tell that this channel is gonna start sounding like a top 10 list countdown channel. It’s really not the same without Thor. It will never be...
I yawn even while cycling, bouldering and other high intense sport activities
Can i get a quick recap for why Kyle left?
I cant feel the vibe anymore :(
The music was way too loud in the mix down. I couldn't hear Dr. Moo. 😕
My theory is that when we sleep we take in more oxygen and when we wake up in the morning we yawn for a kick start to the day and we yawn at night or whenever we normally go to sleep because it's our body saying ok this is our normal time to fall asleep and the empathy thing might not even be a choice for people it is most likely for us to yawn when someone else yawns because it is a instinct of some sort or a involuntary response but that's just a theory a science theory but hey what do I know I am just a kid in high school trying to graduate
Why does reading about yawning make you yawn? Especially when you read that reading about yawning makes you yawn?
I love how they only go over stuff most don't believe is why
They completely skip how a lot of scientists think it could be a let over part of our body an instinct of sort like how you'll typically jump back from a snake because most believe you yawn from when humans needed a way to indicate it's time to best down for the night a wide spreading yawn as the sun gets low saying okay time to get ready to sleep
I yawned 4 times just watching this 😂
Sorry folks, I subscribed to this channel because of Kyle. Can't really get into it without his energy
And then I yawned, confirming my need to unsubscribe. Deuces. Headed to The Facility. Anyone coming?
Me watching this video already seeing Vsauce's
I never yawn. Others yawning doesn’t trigger a yawn for me… I only seem to yawn when I’m anxious. Anyone else?
You have no idea how many times I yawned watching this video.
I think the way to find out why we yawn is in magic mushrooms. when I'm tripping on shrooms, every time I think it's wearing out, I yawn, and the high returns even more intense than before
I know scientists don't believe in God majorly, but could I ask you to analyse the speed of the character samson from the Bible? He managed to catch 300 foxes which can move at 50km/h in 1 hour, how fast would you have to be to manage that feat?
Even talking about yawning is enough to trigger yawning!
I miss the intros filled with tips on how to make my hair look luxurious. I'm balding, but hey you never know.
when running around doesn't work and your yawning gets worse this might sound crazy but bare with me here. maybe, just maybe. it's time to go to bed.
