How the Sun works: Fusion and Quantum Tunneling

[iJamieG97]

but i live in england and the sun never shines so this doesnt apply to me

[MovieTrim]

he wrote quantum physics yet he said thanks to quantum mechanics

[lieinthenameofagospl]

@CONDUIT99PERCENT fuck off. he was right the first time and stop offering youre two cents. its poeple like you who stop use from knowing about how stuff work. were here with no help from higher being. get that right you piece of shit.

[James01100011]

We have fusion powered subs?

[Khriela2Shredd]

your ink is almost empty..:P lol

[CheesyBastard21]

BS!!! GOD keeps the sun fueled by blowing it up every now and again and rubs his ass on it to keep it hot.

[tabaks]

@CheesyBastard21 Ok, now run along, your mom is calling you.

[harkendoich2]

Wish I could download your brain to mine!

[zukodude487987]

I thought the sun works by having alot of mass clumped together. When its big enough its gravity starts to pull itself inward and crushing the core and starts pushing hydrogen atoms together to make helium and releases photons in the process. If your description is correct then even jupiter would have to have some light emission.

[tabaks]

@zukodude487987 It does.

[zukodude487987]

@tabaks This makes me wonder why this video has a completely diffirent explanation. I understand that its a version of quantum mechanics, but still i dislike the fact that there is no mention of einstein in the video, since he was the first person to explain how the sun works.

[silentthrenody]

Loving the psi at 0:50 XD

[mrnarason]

what's the probability of the sun rising tomorrow?

[aluisious]

@fahdmasud It made as much sense as your comment.

[aluisious]

The sun is not like a nuclear submarine in the sky. Subs are all fission powered and the sun is fusion powered.

Really enjoying how misleading these videos are. What are you, a bored grad student?

[RequiemFear]

@aluisious It's a basic analogy, get the fuck over it. The vast majority of people don't know the difference between fission and fusion.

[aluisious]

@RequiemFear It's a shitty analogy that a lot of people noted, which makes this a shitty video from a physics standpoint. This isn't a fucking football video making a physics analogy.

[theflyingass]

@RequiemFear Which makes it even more important that the definitions of Fusion and Fission are clearly defined.

[tabaks]

@aluisious Boy, you REALLY feel smart. Too bad your fusion of character isn't equalling your fission of crap.

[aluisious]

@tabaks Bite me asshole.

[austijams4ever]

they must run out of markers alot

[larllarfleton]

just asking and hoping for a response, but can quantum looping and string theory both be right?

[DanieleGiorgino]

The first thirty seconds are wrong. Subs are powered by fission reactors.

[fahdmasud]

send thanks to the One who designed quantum mechanics. u would understand what i mean if you are a promgrammer

[0909umcia]

@fahdmasud Bohr, Heisenberg, Planck, Shroedinger, Rutherford, Einstein, Dirac, they all had a big merit on quantum mechanics.

[aluisious]

@fahdmasud Go ask the One for a sandwich and leave science alone.

[aido179]

he needed a new marker...

[coconutcreampie123]

please make a video with vi hart

[TheRoyalGanj]

@xIDUALFREEZEIx it does 'convert' through fusion. basically, the hydrogen atoms get so insanely hot that they fuse together to form helium atoms, this process releases huge amounts of energy but some mass is lost as the quarks that make up the protons and neutron have to change about meaning that protons turn into neutrons. If you didn't already know protons and neutrons have different masses (protons>neutrons. so in conclusion some mass is lost and it just so happens this process release energy

[fyocouchnickel]

His "Infinity = -1" thing is false.

[thesourceofx]

@fyocouchnickel prove it. If you mean that the statement "infinity = -1" is false then you are correct. But he wasn't actually trying to prove that. Read the top comment for that video, it sums up his point well I think. Here's a link /watch?v=kIq5CZlg8Rg

[zze4z]

@fyocouchnickel your false

[0Gotland4Ever0]

Hello Minutephysics, how do you know all this? btw love your vids!!!!!

[monkeyman7009]

It feels so good to actually already know how it works :)

[Archy506]

i dont really enjoy the format of these videos, i get it - minutephysics; the video is a minute, but some of these concepts are just so far beyond that format, atleast that's how i feel.

not really satisfying.

[flowiepanda]

@Archy506 as a foreigner to physics, im not too familiar with some of the topics he discusses, especially quantum tunneling. in the end, im just sort of left hanging there. hungry for information, but still hanging

[Archy506]

@flowiepanda exactly. i want to learn about it, but he's essentially read out a bunch of titles of chapters from a book, and not elaborated on any of it.

[grandhacker64]

There are literally several different altercations in these comments. Pullin' out caps lock on youtubeeeeeee

[TheWorldEndsWithUs]

So quantum tunneling is a big "fuck you" to the rules of nuclear fusion @_@

[danosdrake]

The sun is actually plasma (ionized gas a.k.a. Electricity) bundled up into a ball. How do you think we get power and energy from the sun? The sun shoots out its electrical waves in a gamma ray to earth or all around, and that's our solar power.

[Thebrowntown1234]

you didnt explain the not super hot hydrogen binding thing which i wouldnt understand either >=(

[mitkenski]

only thing i would say is that submarine`s reactors do not use nuclear fussion rather fission of atoms the nuclear fussion has not been tamed yet (there is no safe controlable way to produce electric energy through it)

[Ramstaandy]

quantum mechanics is the new god =)

[The0n0n]

Not To God

To Quantum Mechanics

[gregar00]

MY MIND HURTS

[fishyeka]

no give thanks to God

[emikochan13]

@fishyeka Are you really that dense.

[Thorakites]

@fishyeka

*singsong pre-school nah-nah voice*

Some-one's a dumb-ass!

[nmkloster]

There's a reason he starts out stating this is physicists math. One day about 7 years ago during a physics lecture the professor paused his calculations, looked at us and said: "Don't let any math students catch you doing integration this way. You'll probably get shot."

[piecharthosen]

@nmkloster oh man I'd love to see that just to troll up some math kids. what was he doing?

[nmkloster]

@piecharthosen Don't remember exactly but it had something to do with rearranging some dx, dy and dz's around while making a few shortcuts.

[Narftaxaku200]

Fusion happens inside the sun because the sun is big fat and hot, too much pressure and temperature. Quantum tricks happen most of the time at sub atomic scale.

[JamesCizuz]

This is not technically correct. The fusion tempeture of an atom changes depending on pressure. While on earth it takes 100 million C to fuse a H atom to He; that is with earths atmospheric pressure. In the middle of the sun the pressure is so great the fusion tempeture drops to 10 million degrees. Fusion only happens roughly around the core/outer core. While quantum tunneling may have started fusion; it's not the primary cause of it in our sun.

[PykohYT]

Khan Academy in the tags. Awww Yeah.

[MrJKMills]

dude, get a new pen

[ea5ymoney]

blues clues anyone?

[Rosyheart1]

"Small Chances" happenin all the Time, why wouldn't that "add up" be a Great Big "Chance"? 4 billion Years' ain't small Change, is it? {Helios, Reality Checks don't bounce, hehehe*}

[ulkord]

@Rosyheart1 because the chance is not going to change no matter how often it happens

[RoySchl]

so subs use fusion now... must be a really secret submarine

[ulkord]

@RoySchl yes they have lasers which are adjusted to make like 1 single laser which then heats up an isotope to about 100 million degrees celsius

[joemomma824]

lmfao enron

[ghostmaster24]

I always thought that the extreme density forced the atoms to fuse even though they're not that hot

[TheDivineWinds]

Cold fusion!

[jessiifosburg]

I love the arguing like everyone thinks they are a damn scientist trying to prove each other wrong.

[alecazam3567]

@jessiifosburg lmao only an atheist is able to argue about religion on a physics video xD

[ChikoWhat]

@jessiifosburg To tell you the truth, that's how discussion works in the science world. the NO U arguement and whatnot.

One makes a theory (means it's no far proven or is the best current explanation)

People try to prove eachother wrong to get THE RIGHT ANSWER.

[rugsyofspurs]

@jessiifosburg some of us are....

[livedandletdie]

@jessiifosburg You're wrong. LOL

[Customgamer9]

@jessiifosburg tis the internet mate, everyone has to know more than these people they don't even know.......

[AXiSxToXiC]

What did you do on Freddiew's video? :D

[nmkloster]

Really? I thought it was just heat + pressure and there you go... I am a little sceptic after the whole infinity = -1 though :)

[MSJjoshua]

@nmkloster There's not enough heat to classically induce fusion in the sun.

Also it's "skeptic".

[nmkloster]

@MSJjoshua Ok, skeptic. And you play football with your hands... Pffff!!

[MSJjoshua]

@nmkloster ???? I don't play football...I hate football. Both association football and American football. I respect the players, but I don't like the sports.

[nmkloster]

@MSJjoshua Don't care.

[MSJjoshua]

@nmkloster Then don't comment.

[nmkloster]

@MSJjoshua

---------(point)------>

Joshua

[TeapotFTW]

@nmkloster so what does infinity equal?

[euducationator]

@nmkloster he did not say 'infinity equals -1' he said (1+2+4+8+16+32...) is not infinity

[nmkloster]

@euducationator "So it's pretty obvious that the sum is infinite"... and also it IS infinite. There's a reason he starts out stating this is physicists math. One day about 7 years ago during a physics lecture the professor paused his calculations, looked at us and said: "Don't let any math students catch you doing integration this way. You'll probably get shot."

[euducationator]

@nmkloster that would be heat times pressure

[lukeskymac]

@nmkloster as far as I know, it IS just heat and pressure... and a lot of people where claiming on that video that the answer was ∞-1

[fuzzy987321]

@nmkloster He didn't say infinity = -1 dude. Go watch that video again.

[nmkloster]

@fuzzy987321 Holy image of Jesus on a crap-filled cracker! How can I be getting this much heat for a smiley comment!! From a mathematical point of view that IS what he is saying. 1+2+4+8+... is a divergent series with the sum of ∞. If you are not satisfied this is the case Knut Sydsæter has written some decent textbooks on the subject. I am not oblivious to the point MinutePhysics is trying to make: Even though you are adding up the numbers and well on your way towards infinity...

[nmkloster]

@fuzzy987321 (CONTINUED)... once in a while you'll encounter a negative number ahead of time and for a second you will have a negative value overall even though the sum was steadily growing. This point is quite well illustrated in the quantum mechanics video from MinutePhysics.

[nmkloster]

@fuzzy987321 Also see the above statement directed at euducat...

[DocPixelator]

@nmkloster Exactly. Gravity=pressure=heat (ideal gas laws). the sun has a lot of mass ergo a lot of gravity ergo a lot of heat. I have already only seen 2 of minute physics' videos (infinity = -1 and this) and he has, in my eyes, already lost all credibility. The probabilities he is speaking of are so unlikely that if *that* were the driving force behind fusion in the sun, it would be slightly warmer than a desk lamp. Totally agree with you.

[Anthonyk312]

@DocPixelator

1. He's right though, quantum tunneling is a significant factor in the sun's fusion.

2. If the sun were powered by only the heat generated from gravity, it would only last a few million years.

[flowiepanda]

@Anthonyk312 heat is generated from gravity? D:

does obama know this?!?

[Anthonyk312]

@flowiepanda heard of the core? Ever wondered why it was so hot? Because of the extreme pressure caused by gravity, the temperature rises.

[flowiepanda]

@nmkloster it was to emphasize a concept, woman! don't hold it against the man!

[TheBalleKiller]

i got 12/a+ in my project about the Atomicbomb :D

[fizzlemanizzleable]

great video but what happens with the hydrogen when there is a solar flare?

and how does a solar flare occur?

[DarkGraff1]

no God made the sun 6000 yrs ago.



[YOUNGTALENT2010]

@DarkGraff1 lol that made me laugh

[Smartboy7]

@DarkGraff1 Why are you even here? I bet even religion can't answer that.

[DarkGraff1]

@Smartboy7 the BIBLE has all the answers son...;) read it

[Smartboy7]

@DarkGraff1 It has answers, indeed. But not all. If it did, it would be of infinite proportions.

[Thorakites]

@Smartboy7

Cmon', that guy is fucking with you, lol, don't feed the trolls. :)

[oneNaiveAlien]

quite the opposite: give a thanks to the sun shinning tomorrow for the existence of quantum mechanics ;)

[TastyLaserCakes]

Or God... you know... but whatever =)

[Thorakites]

(cont.)

Just thought I'd ask the rest of you, as this guy is really getting agitated, and maybe if I actually know what his issue is I can make some progress.

Danke schön

[Thorakites]

(cont.)

I argued the points that were given to me, one by one (it's hard to do otherwise with this shitty comment system.) Basically, I'm asking ANYONE who can to please, if you might think you know what the hell that guy was trying to say, to attempt to explain it in a simple manner. All I got was a jumbled mess of things about how "reason" affects probability, or something of the sort, and honestly I still have no idea what problem he even had with my original comment. (cont. again)

[domomomo1]

WHY HAS THE SUN BEEN HERE SO LONG? ISNT IT OBVIOUS? CHUCK NORRIS ISNT DONE WITH THE UNIVERSE... YET

[Thorakites]

Just a general comment to everypony:

My original comment that some people had a problem with essentially stated that because two separate beliefs (the belief in god and the belief in elves, for example) have the same lack of evidence, they have the same possibility of being true, regardless of other aspects of the myths.

I'm still at a loss to exactly what the argument was against this idea, it was never stated in a manner that made sense in a logical context. (cont. in next comment)

[ponynomial]

@Thorakites Physics, ponies and logical argument? I approve of this. And no, there is no argument, don't worry. 

[Thorakites]

@ponynomial

:D

[domomomo1]

THANK U QUANTUM MECHANICS!!!!!!!!!!

[TheAnit500]

there is only one problem i have found in this video and that is that nuclear subs do not use fusion they use fission. the splitting of atoms. they both operate by the same principle of destroying mass in the reaction, turning it into heat via E=mc2 but fusion is still extremely hard for us to produce on earth and we have never made a fusion reaction where it produces enough power to supply itself with the heat required. if we did we would have no need for fossil fuels anymore we could useH20

[ShiroKage009]

That's similar to the principle of activation energies and how there's a small chance that, even in unfavorable conditions, a particle or two will proceed through the reaction if the result is thermodynamically favorable.

[uratoko]

>>>------(HEAD)------>

[DonnaPinciot]

maybe you could try to explain how human brains work, how we think and reason and solve problems and such, or why life exists? and how it exists

[Livingonthecheap]

Doesn't the pressure of the extreme gravity play a role also?

[andreagir1]

I wish you taught my physics class. You make things very easy to understand!

[Stormeris]

MY HEAD HURTS

[Daud431]

@aflashlight OH i see if my English really offended you...i really don't give a fuck...... i hope your ass less stink then your mouth...

[aflashlight]

@Daud431 I'm sorry. I meant it jokingly.

[IBelrose]

How is Quantum Physics trademarked?

[maxullins]

Trying to find Thorakites comment.. Running low on su-

Holy fuck it's everywhere. O.O

[Thorakites]

@maxullins

I assume you mean the number of comments I've posted, in which case I can only echo the surprise, as honestly it doesn't feel like I've commented that much. :P

[maxullins]

@Thorakites Well, not how many comments you've posted, but how many times your name is mentioned on the page. 218 times as of now.

[kvnyay]

Holy Crap!!! If you search for Thorakites' comment its freakin everywhere!!!

[LtMarksLixer]

four and a half billion years.... even though its only like 30,000 years old.....

[NatureTrailPromo]

sounds like a shitty explanation for something you can't explain

[StaticLucky]

@rerere284 then, it wouldn't be called energy. energy can not be destroyed or created. it's conserved. thus conservation of energy.

[Jimm607]

@StaticLucky In that sense, i believe that the energy is simulated also, and isnt actually real energy, arguably if we were in a simulated reality the laws we observe may not be those of the non-simulated reality.

But im fairly convinced we arn't in the matrix.

[gregslife7]

so basically quantum tunneling states that there is a very small chance that matter will just blatantly defy the laws of physics and do whatever it wants?

[domomomo1]

@gregslife7 to a certain degree yes you are right

[SuperSaucyFellow]

@Thorakites

How so?

[TheiNNA88]

That's it . I'm switching majors. loll

[zigge6zzz]

I was surprised of the fact that the sun would burn up in a short time if it was made of oil or otherwise combusted (slightly). But why does it burn i a controlled manner and not in a chain reaction like a H-bomb all at once?

[Apapilootoe]

@ShadowAbsol1000 HELL YEAH!!! AN ATHEIST!!!

How the Big Bang or the Universe created? If there's a creator, how the creator created? If there's another creator, how that creator created? If this goes on and on, well, that would be impossible. THINK ABOUT IT.

[rerere284]

@Apapilootoe

It could be that all this is simulated, and in the realm where that computer was made, it makes sense for energy (or whatever you would call it there) to be created and destroyed.

[Apapilootoe]

@rerere284 What te heck are you talking about? This is about God.

[elpelu123]

is it me or the so called quantuum mechanic is like a way of saying... OH!!! This doesnt work... No worries i pull the solution out of my hole...

[andrei6698]

i wish you're my science teacher

[Thorakites]

@SuperSaucyFellow

Hmm, I dunno, maybe because the Bible has been disproven, and it's not accurate at all.

[Apapilootoe]

@Thorakites Are you an Atheist? Because if you are, I'm gonna ask you.

[ZGBradley]

@minutephysics you do more complicated quantum stuff about reality and stuff

[AlBarathur]

Sure is must be quantum probability, it could not be the stellar level of pressure created by gravitational forces which would also explain the core being hotter than the surface, and the atomic processes being more intense where there is more pressure...and that H bombs work the same way and need pressure to reach a critical mass that will allow the chain reaction despite the fact that the material is the same therefore the probability of quantum fluctuations being the same without pressure.

[AntonioVassZanBomber]

Nice Crayola commercial!

[Cantketchup]

kinda of like even if water hasnt reached it's boiling point, some of the molecules still evaporate. right?

We all live in a yellow submarine...

[Girugameshification]

yes this is what i have been looking for my entire life

[nieveg1]

lol he spelled Pangaea wrong

[camo0067]

Could you do a video over the Chaos Theory. I'm not sure if that has to do with physics or not but it would be cool to see your drawings of it.

[DaceTheBase]

@Tapitlightly1 I looked up that exact verse, but I didn't see it in the entire chapter. And what kind of username for a Bible scholar is that?

[zaqareemalcolm]

@quosmo1 Basically, its just particles surmounting a barrier it usually cannot pass. And, if there is a God, it would be obvious that hes outside the system that is our universe, but thats my view anyway

[HurrLogicAttackDurr]

if we measured the sun would we collapse its wave function and burn it out?

[zaqareemalcolm]

@Thorakite Quote "Science is capable of ascertaining causes from observed effects only if those causes are internal to the system being tested. The naturalist believes that only causes within the universe will generate effects that are observed by us. Observed effects will never have causes external to the system in which they occur."

[Thorakites]

@zaqareemalcolm

Aaaand what does this have to do with anything?

[thebigrussian]

Give thanks to quantum mechanics? Lol, thats like saying man is the reason the sun shines.

[allskin24]

@thebigrussian errrr... yeah it is if you think more about it youll see

[quosmo1]

i dislike these kind of explanations.

its basically saying we dont know why the hydrogen atoms fuse at lower temperatures, but that since our maths cant disprove it, it must be remotely possible in some random event, the sun is big, with lots and lots of hydrogen so these random things must happen a lot.

i hate it, its not a real answer!

its like saying we cant disprove a god, yet however remote a possibility if the universe was big enough he MUST exist : bullshit! bullshit! bullshit!

[samandsimon227]

@ShadowAbsol1000 SHUT Up!!!

[cubenori]

"Did you know that if the sun were fueled by combustion of, say gasoline or wood, it would burn out in just a few millenia? So how is it still here after 4 and a half billion years?"

.....Aliens

Crayola should sponsor this guy.
