Scale of Earth and Sun

[ECHDoc231]

awesome videos man!

[morethanlyf1]

Great info. This would be very helpful.Thanks!

[nonchalantgamer]

Here's something interesting to the think about:

Even the most brilliant scientists (Carl Sagan, Michio Kaku, etc) can't fully comprehend the scale of celestial bodies and solar systems.

[QadirPopal]

Thanks a lot...

[mucker3000]

This video is for noobs.

It takes a jet aircraft 1100 years to travel around the biggest star known to man. VY Canis Majoris.

[pielover8888]

@mucker3000 Umm, since im a super nerd, you are the ULTIMATE nerd. Congrats! :D

[Redline748]

right so the depressing conclusion is we will never travel to another star system

[uknown786]

your handwriting is top

[P4TTL2]

@brooksy2777 yh as the other guy said its no longer classed as a planet, scientists got together to give a minimum size to consider something called a planet..and well pluto didnt make it im afraid :(

[ArsenalDave04]

@fox2011uk there probably are kid watching you retard

[skettysi]

I love biology I do

[Shmiefman]

he said "more huger" 

[andylufc92]

This is all incorrect.. Earth is bigger than the sun. The government want us to believe the sun is bigger so we all feel inferior and allow them to rule over us. Fight back, the world is bigger than the sun!

[oOboobviolatorOo]

@andylufc92 you are just stupid... stop trying to troll, your shit at it

[adphlash]

This video was clearly made for total retards

[MrHarrydix]

40 hours

[Eisbreaker1]

@brooksy2777

Pluto is no longer considered a planet.

You can thank Science(tm) for that. :D

[PoKerFaceN1]

wow awesome love it

[brooksy2777]

why is the 9th planet (Pluto) missing on that third diagram?

[rabd1967]

@brooksy2777 not positive but pretty sure they decided that pluto was just a big lumpof nothing lolol

[Red240104]

Its like listening to Fred Elliott, i read once the earth can fit in the sun 300-400,000 times over. nd the explosions are the equivalent to 1 billion tonnes of TNT exploding each second. We can see it nice nd big on a clear day, but it doesnt see us nd never will. Awesome

[bucketrobbert]

whats that in miles from england

[tgrdtgrd]

The comments used "repeat" 68 times. This makes it a nice, even 69 (heh), now where the fuck is my medal?

[iainreekiecouk]

According to their blog,10% of women on OkCupid, and 5% of men think the Earth is bigger than the Sun. *weeps*

[kionaramirez]

17 years, 17 years, 17, 17 years!

[sagaciospianoman]

reverb....reverb....thats reverb...

[jackosjack]

[TheSmiler62]

There is a distinct annoying echo in the commentary lol

[TheMatthewLomax]

[NoirGames]

THIS IS UNDERSTANDABLE.... FUS RO DAH!!!!! (Skyrim)

[jakethomas55]

Very annoying how he repeats himself all the time

[GenericCoder]

People who keep saying its annoying etc should stop watching, so the rest of us who want to learn something will not be annoyed by your comments.

[gavin93100]

i would say with the bullet traveling round the earth, and it takeing 40 hours that there is a variable, as the earth its self is moving so could take longer of shorted depending on the direction you are traveling

[thedisneypriestesss]

@gavin93100 LOL

[lfclad97]

THEN DON'T WATCH IT - AT LEAST HE'S GOOD AT EXPLAINING IT!!!

[SuperCQC]

lol he repeats it so much so it sticks into ur head, it may be annoying at times but that is how most things are taught. by repeating it so much that u start to repeat it and actually learn

[billysandy]

you need to stop repeating yourself, repeeeaaatttinggg yourself repeating yourself

[KialraOfDeath]

Rajesh Koothrappali, is that you?

[PygeonKilla97]

i think he's broken

[GenericCoder]

Wonderful video hes repeating for emphasizes in order for your mind to get the knowledge better :) .

He's taking time from himself in order to provide us knowledge,so you guys should stop acting like bunch of kids.

[ray123ification]

"The Sun is far 'hugher'..." What sort of word is 'hugher'...?

[saxcoburg]

boring and uninspired - like eating cornflakes.

[teesfella]

wonder if he repeats like that when phoning for a pizza...

[huckrj7]

if you did fire a bullet at the sun , there is no air resistance in space so it would keep its volocity

ooooooo i feel clever yaaaay !!

[eric10glitcher10]

@huckrj7 ...If you were in space when you shot it. You couldn't do it from Earth. :3

[huckrj7]

@eric10glitcher10  well obviously clever cloggs :)

[WAAAAAAAZAAAAAAA]

Jesus, you're so annoying, Jesus, just repeat everything like four times, you're so annoying, you just repeat everything like four times, Jesus!

[Ericano6]

[BrokenWaggon]

i like how he repeats things it helps me remember it better

[ransco1000]

[MrSimmondsTeaParty]

[JSDW1]

I get the point, I get the point, I get the point



[readrats]

I need to change to the metric system, so easier, also I'd like to thank my 8th grade math teacher for showing me this website/videos teaching

[TurkeyTruffle]

what are those specks on the map of the solar system? below the planets one between mars and jupiter and one after neptune?????

[LiteralGaming]

Yeah but you wouldn't be on a jet liner. You would be on a spaceship, also you're are not factoring in that you wouldn't be flying over the surface of the sun, you would be above it which adds more time. Still a good video.

[LiteralGaming]

40,000 kilometres, 40,000 kilometres, 40,000 kilometres, 40,000 kilometres, 40,000 kilometres, 40,000 kilometres, 40,000 kilometres, 40,000 kilometres, 40,000 kilometres, ...........

[aaroncassidy7]

if hes using his mouse to draw them letter and write those words, i would be pretty impressed :|

[Kalbaloo]

@aaroncassidy7

He uses a pen and sensor pad.

[fiestathebest]

[iwc62]

[MichealJackson29]

40 hours 40 hours 40 hours muthafucka i said 40 hours!!!! :D

[Andytheblue]

I feel like ripping out his voice box

[MirHassanProductions]

Before I watch every video, I read the comments and see what people think about the video, when I saw the comments about this guy repeating himself, I clicked away and then came back to make this comment, just in case anyone asks.

[WWEFREAK372]

[WWEFREAK372]

[CocoaLuv22]

so everybody knows the earth is blah blah blah the size of the sun.. but tell me how a star the similar size of the sun can give us a solar system to provide us with natural resources to steal from another planet.. anyone can do a conversion.. GUYS IF YOU TRAVEL AT LIGHT SPEED, IT TAKES 10 YEARS TO GET TO SOMETHING 10 LIGHT YEARS AWAY.. @khanacademy if you're not talking about wormholes, blackholes, light speed or resources on other planets/moons in our galaxy then forget about astronomy

[WWEFREAK372]

intelligent

[eLuzioNHD]

Its Over 9000 !!!!!!

[PunisherLobo]

man this video is an pain in the ass for some atheists!!!

[LordReapr]

he's repeating himself because he interprets his audience to be comparable to 5 year old kids. Repetition is like smacking you with knowledge until it gets into your thick skull.

[Orangebeastage]

@LordReapr you would know. :)

[levit8dude]

annoying bastard. are u a parrot?

[Zonitricoxide]

this guys annoying as hell

[Thorleyart]

repeating your words over and over is exceptionally irritating.

[FinalChapterFilms]

[llangol]

How do you think we can't take this on, dickhead

[llangol]

[Nasir1uddin]

the last planet is sooooooooooo cold because it's away from the sun.(At least santa likes the last planet and getting away from the sun)

[beavorpigs]

I saw that the video was 9 minutes and thought I wouldn't watch it all. 9 minutes later i'm commenting on the video. Very interesting.

[MrMichaelpaul45]

Nice video fella,i like it,interesting as well,but did you no,my be you do no my be not, but you can fit the earth into the sun over 1,000,000 million times.WOW WEE :-).

[ColinC33CFC]

how many times do you need to repeat your words? We get the point...

[DarnDatDiddy]

Great lesson.

[JoeDoesGaming]

That's Amazing, Subbed

[YouDontForgetThis]

woooow, this is so interesting! I love stuff like this so much, and you really break it down and make it understandable (even if it is crazy!) I wish I had the grades to study astrophysics or something like that, something spacey!

[woody91z]

funny



[ootakifumiko11]

i like it!!!

[TheAlistair111]

you have really nice handwriting

[wayztan]

[Solidfox154]

How insignificant we are! and some will say we made by coincidence, I am asking you ...do all these large objects made by no one and nothing??? and will answer... we dont know yet,, lol ... then you never know who made these things.

[StrykeEvil]

i hate how he repeats everything!!!!

[lfclad97]

@StrykeEvil then dont watch it

[Orangebeastage]

he explains things really well, his voice isn't annoying. But the way he repeats everything 3-4 times. is abit annoying. is abit annoying. is abit annoying. is abit annoying. is abit annoying. is abit annoying. is abit annoying. is abit annoying. is abit annoying. is abit annoying. 

[MrDougiemo]

@Orangebeastage i like your comment apart from the fact that "abit" isn't a word

[theinformationplanet]

@Orangebeastage He is just repeating for emphasis, almost every teacher does that...

[lfclad97]

@Orangebeastage OK that was quite funny - but if it annoys you don't watch it 

[Orangebeastage]

@lfclad97 But it's interesting so i'm stuck D:

[RMCKIE]

Interesting but could be put into one sentence.

[PizzaBlade17]

Sometimes i watch your videos for fun. Becuz you explain these things in a way that show how cool these subjects (Math, Chem, Bio, etc..) really are. Thanks!

[MagicReborn324]

if you keep on pressing 6 u get penis penis penis lol :) no wait i mean 7

[MagicReborn324]

if you keep on pressing 6 u get penis penis penis lol :)

[samleegarbett]

can you repeat that? i didnt quite get it//

[JoshW272727]

If you randomly pick a number between 1 and 9 during the video and press that key repeatedly until it gets annoying, miraculously the video doesnt really sound any different..

[davehowellman]

I'm at 1.46 and really bored!

[tsuchan1]

It's so patronising.

[MrEuroFly]

khanacademy, you trying to tell me an AIRLINER travels at the speed of a BULLET? You sir are a moron. Get your facts right. Get your facts right. Get your facts right. Get your facts right.

[Kalbaloo]

@MrEuroFly

He is right...

[MrEuroFly]

@Kalbaloo Categorically incorrect.

[ItzBassi]

@MrEuroFly He said JET not AIRLINER???

[scottbw12]

@MrEuroFly open your mind, and your fucking ears before you leave a comment

[MrEuroFly]

@scottbw12 i did, i researched all the facts after watching this video. He is incorrect when it comes to the speed of a jet/airliner been the same speed as a bullet, look it up yourself.

[alister113]

My penis is much bigger, much bigger, much bigger than yours, yours, yours.

[namybot]

Thank you for making it clear how big our universe is.

How does he write this fast by using the mouse?!
