The Doppler Effect

[CTFxCsoldierNumber27]

this gets mad annoying when played 5-7 times in a row...

[AthosAmo]

1: 46 "Because all galaxies show a redshift in the colour of their light..." LIE! Andromeda is just one of many which blueshifts, propaganda liar.

[xGodzAssassin]

i have a science GCSE on physics an this video explained the expanding universe topic so much thanks, time to ace this exam lol :)

[GrimCronus]

@xGodzAssassin Same here, thanks for showing this to me :)

[thisguyrocks0909]

Sheldon: "I'll give you a hint: 0:54!!"

[PattW6]

Helped me understand big bang theory :)

[GODLOVEEESYOU]

Oh so this is what it is thanks sheldon ahaha his costume

[moorditjman]

good presentation dude, helped me alot with essay

[CpsLock3]

PICTURES!

[Xavierrex3]

thumbs up if you didn't get here from some faggy sitcom.

[SVMaverick98]

I came here because of The Big Bang Theory! Love that show! Thank you Dr. Cooper!;-) LOL

[broken302011]

Sheldon led me here! haha

[IIIIIIIIIIIIID]

thank fuck for this video

[doseiaisha]

OHH NOW i get it! i feel smart! XD

[DNYAP]

NOW I UNDERSTAND!

[JCE8705]

Big Bang Theory FTW!!!!!!!!



[blakeunwin]

thumbs up if you're watching this for homework!

[stoomthoom]

big bang theory rocks hahaha

[muntaha1231]

i don,t understand that how the world is scattering?

[drummer806]

best explanation on youtube

[TheHobNobLover]

thumbs up if youre watching this coz of school :P

[Sk8zdela]

palac gore ak si ovdje jer te borjanovićka poslala!

[nickyboy1309]

thumbs up if u watched this because of ms.coyne(rogak) from newfield long island

[freakychannel123]

tu dududu..du du..

[MrShroubles]

I find it hilarious how every science video ever has a low budget animation.



[NoblesInTurmoil]

@salmonling Heinrichhhhh!!!

[whyhellothereXD]

I found this hilarious for absolutely no reason whatsoever

[salmonling]

THUMBS UP IF YOUR FROM RANDOLPH HIGH SCHOOL and heinrich sent you here

[TheCaoth]

The explanation couldn't be clearer. I've always thought that a police siren had its normal pitch while coming closer, whereas it's really a higher pitch.

[ashkibala1]

0:40 "the first ahead of the source are bunched closer together" why do they get bunched?

[basisrecheneinheit]

loved it!

[dummychaos]

I wish it was Sheldon who brought me here, cos he's the coolest. No, only curiosity brought me here. I'm so boring.

[elen900]

@dummychaos Yes, the same goes for me, though Sheldon is the best.

Why?! Why am I so boring?!

[SnipeSpace]

oh Sheldon, what would we do without you

[deadmandying]

hahaha thank you so much, i missed my physics lesson on this and 2morro's there's a huge test on cosmology and astrophysics XD

thanks again :D

[raizentoushi]

i bet this is sheldons ideea of cartoons. :D

[ultrasonictechnology]

nice demo . Extremely good

[TSPURSBOSS]

BAZINGA!

[geocioncan]

Lol I have the exact same mitsubishi lancer model :D

[Muarkuss]

those ripples would bounce off surrounding solids. fail. muark. and the ripples seem 2d in space. fail.

[Loriiik]

or maybe were getting smaller!

[Filipa1122]

@Loriiik it would all be blue then ^_^

[zeekoegoesboo]

i see...



[TheSeditionary]

1:43

"a red shift" jesus christ a what!?

"red SHIFT" oh okay

[ADNAN92FLY]

not at all



[beaverfeaver12]

this is insane to watch when your high

[BarbiexCutie]

THANK YOU. :)

[rgrggfdgfgr]

hey at least there are many galaxys coming closer to us so we will still have many places to explore asuming its 100s of years b4 we are able 2 anyways.

[laurabob05]

Nice animation, perfect for my physics class

[Samo762]

I like the Cosmos version more

[snaptraks]

-I'll give you a clue; NIIIIIEUUUUU

-Euh, a tchoo tchoo train?

-No,... NIIIIIEUUUU

-Euh, a brain damaged tchoo tchoo train?

[Olivia1496]

I get it yesssssssssss :D

[Tokiohotelgirl97]

oh my god i get it now!!!! THANK YOU!

[UnitedMSN]

thanks

[mkt778]

"Dum um num dum dum..."

[theIGNentertainment2]

this just reminds me of the 5 page question i had to do involving the doppler effect.

[theRYNchannel]

The light doesnt compress!! light moves at the same speed no matter what speen you go.

[thatguywithnoname]

@theRYNchannel It's not the speed that's changing, but the wavelength.

[ianng]

thumbs up if you watched this because of Sheldon

[regeleio]

@ianng omg ... i did it because of sheldon <3

Halloween Episode <333

EPIIIIC !

[jas0123]

@ianng I seriously thought I was the only one here because of the big bang theory :P

[xema234]

@ianng i watched it becouse im intrested in physics not sum retarded tv series

[resinated420]

@ianng i so want his shirt, it would be effen tight!!!

[kakefyll]

@ianng And they say you don't learn anything by watching TV? xD

TBBT has taught me alot

[cmpinkluvr]

@ianng ahahahahahah i love you

[hill1916]

thank you

[Becx001]

Thanks for the information!

[macmediabug]

Well described! You're improving the world one IQ point at a time.

[AbyssalRose]

NEEEEEUUUUUU!!!!

[borednerd74]

Now I get it! Cheers!

[DrWeaselteets98]

Now i know what the hell this is.

[NasirHabib]

simple and affective!

[12gauge99]

ha the only reason i looked at this was because i was watching the big bang effect to see what sheldon actually was at the party :D

[sharoo14]

@12gauge99 big bang theory :) i love tht show tooo

SHELDOOOOOON <3 .

[mnesberg32]

Wow, great! My students will love this!

[bravestory2007]

Thank you for the detailed explanation. I understand the Doppler Effect much better now.

[deerboned]

This was extremely helpful in explaining a difficult to understand topic. I am using this in my class this week for my students.

[Epsilonrolab]

el efecto doppler es mucho mas complejo que estos ejemplos

[goingcruising]

very good demo and graphics for my class. Thanks.

[zealcore]

This is a great clip! Very helpful and it only took two minutes. And it was funny too.

[FIREVSFIREAPPLEBOMB]

Very helpfull thanks!

[brapp3470]

And why does it look red???

[alligatortoiletpaper]

@brapp3470 the wavelength of red is long

[EscuderoFrancisco]

@brapp3470

red has the longest wavelength in the visible spectrum. As galaxies move away the lightwaves are longer... thus red color. If on the other hand you see blue... they are moving closer to us (blue has the shortest wavelength in the visible spectrum).

[kobrajesusreturns]

thanks i feel smarter now

[josenros]

Someone likes Terry Gilliam...

[dillonrockband]

do dodo do duhdo...lol

[MadsNoid]

Thank you so much!!!

[bakinblack1]

Do do duh do do!

[pithikoulis]

I didn't understand much that about colors. What if the color of a star is just because of gas or sth? The the blue or red color is not because of the speed oO

[salesman990]

@pithikoulis wavelength determines colour and since the wavelength is bounched up or elongated there is percieved difference.

[Zamolxx]

It's about wave lengths, the redish or bluesh shifts are percieved "near" the sun, which can be blue, green, yellow etc, depending on its composition.

[Noobless1000]

oh wow when some one told me that, i couldn't comprahend it wasn't me it just was my friend not able to .. i obsorbed this info in a flash :D when told properly :)

[musicartsliterature]

thanks very much, it helped my physics project alot

[Tokse]

Thanks, that was easier to understand than reading about it in my textbook;)

[perverder]

If all galaxies show a red pich if u may, and that means it's traveling away from us.... doesn't that mean we're stationary, or at least the center of the universe?? all of galileo's work for nothing. he would be proud!

[Tonyfusillo]

If everything is moving away from each other, we do not need to be at the centre.

In any position we are in the universe, according to the big bang (which actually wasn't a bang at all, rather than a sudden extreme expansion), things are moving away from each other.

[K2Tanner]

Most galaxies are moving away from each other in general so inhabitants in those galaxies might all feel the same way.

Andromeda is nearing us though, it and our galaxy are pulling towards each other along with an handful of other galaxies that all kind of spin around the same central point.

Correct me if I am wrong about our group of galaxies though.

[RLeungKC]

@K2Tanner you are right about our cluster of galaxies which includes our own milky way and andromeda.to understand this phenomenon, you should search the effect of dark matter on our universe!

[sagoorbest]

its all relative...

[PS3N]

ok so this kind of proves the big bang..? but the little pea (or whatever banged xD) must have come from something. what do you think, or have you read any scientists' articles about it? :P

[andreiduffy]

i mean blue

[andreiduffy]

but how do you know that red shifts exists, if all the universe is red shifted

[Ke2]

Maths, science, history, unravelling the mystery, that all started with the Big Bang!

[SkyGrain]

it's the theme song for the show "The Big Bang Theory" right ? :D

[willbut14]

very clear and simple

[bokkenknuser]

Cool :D

[kelvinios112]

thanks its verry helpfull

[mademcod]

LOVE IT!

[fadyrefaat]

it's a gr8 demo

[ThatsSoRichard]

Nice demonstration of the Doppler effect.

[tychomag]

Love the Monty Python-esque animation!
