What is a Neutrino?

[mysterysqwash789]

What's the mirror image of gravity?

[Lightbulbz1357]

If it's like a sonic boom for light, than it's going faster than light, wich has been prooven impossible by Stephen Hawking. Just taking that into consideration.

[quagluplasm]

@viakth8 The speed of the photons of light is always 3x10^8 m/s no matter what. Water does not slow the speed of the photons themselves, it changes the speed of the propagation of the wave of light. The speed of light itself never changes, but the speed of the propagation of the wave does. The electrons move faster than the phase velocity of the wave, not the group velocity. As the electron moves, its electric field excites electrons in the water, which fall back down and release blue photons.

[d2kagw1]

You have good diction.... :)



[QwertyCharlieFourate]

how do you spell the radiation emitted by a particle when it travels faster than the speed of light (relative to the material it is in (i suppose)) ? Gerenkoff?

[kooksies]

@QwertyCharlieFourate it is spelled cherenkov :)

[xXjesperoXx]

I see what you did there...

[Azdsts]

the neutrinos...they've mutated !!11! :O

[CaMaRo1RoC89]

when i die i only have one wish. and that is to know it all.

[jmohr13]

I'm sorry, but that is not a dalek. It is clearly one of the laser cannons that defended Hoth, only re-purposed to shoot bullets.

[doomdragon319]

ive noticed that on cience videos the comments are always longer

[BlackLink27]

00:14 Nice Dalek.

[RavensDagger501]

@BlackLink27 Looks more like the Echo base turrets from Star Wars...

[BlackLink27]

@RavensDagger501 Fair enough.

EXTERMINATE!

Mirror image meaning anti matter

[plorff]

0:33 electrons are faster than light?

[LeOceanLia]

What does is the universe's "mirror image"? I don't understand...

[LiftMyEyes121]

0:12 looks like a Dalek <3

[Vayashan]

i almost forgot to fave this vid. You sir, are a scholar and a gentleman.

Daleks dont shoot bullets....

[125sonicboom]

@mtdeezy That's why it's called " MinutePhysics".

[mazureac]

good show, very bad conclusion.

[eltotoX]

Why did you change the S for an X when you wrote Universe upside down?

[mtdeezy]

I hate watching short videos like this that try to explain complicated things in a couple minutes. When I clicked this video I was actually interested to seriously learn about neutrinos, but all I got was a bunch of vague information with zero scientific explanations or intuition.

[itsrandomvideotimexD]

was that suppost to be a dalek? haha

[FondlesInTheDark]

WTF?

[tabaks]

@FondlesInTheDark Just keep on rocking in the corner, don't worry about thinking.

[ImperiustheGreat]

0:06 light is electromagnetic interaction? since when?

[tabaks]

@ImperiustheGreat Since you stopped going to school (1-st grade).

[viakth8]

0:32 Made me very uncomfortable... elections have mass and can convey information... so if you were to have a neutrino knock into one sending it faster then the speed of light, you would be sending usable information faster then the speed of light... I DON'T LIKE THAT!

Someone please rectify my shaken belief in modern-day physics please, Im very confused...

[HapplyFace]

@viakth8 future internet my friend :)

[CommanderOrion732]

@viakth8 The key thing to remember here is that this is in water. Light slows down when it enters a different medium, such as water. This is the reason for refraction. So the electron goes faster than the speed of light in water, not in a vacuum. Neither neutrinos nor electrons can go faster than the speed of light in a vacuum (the experiment that detected neutrinos going faster than the speed of light turned out to be a mistake.)

[700718756]

@viakth8 The electron is being knocked faster than the speed at which light travels in water (which is slowed down), not faster than the speed at which light travels in a vacuum.

[AtomicWillow]

@viakth8 The speed of Light in A vacuum (c) is 3x10^8 m/s, the speed of light in water is 2.25 x 10^8. So an electron moving greater than the speed of light in water (by a fraction) is still moving slower than the speed of light outside of water (c).

[direghostman]

@AtomicWillow the speed of light is constant in all frames of reference. water travels at the same speed in water but it is hitting particles that appear to slow it down. and electron moving faster than that light is moving faster that light in the frame of reference.

[XxmynameboratxX1]

@viakth8 Just a shot in the dark, but maybe because the speed of light underwater is slower than the speed of light in the atmosphere. So the electron isn't moving faster than the speed of light through air but rather the speed of light through water. :p

[GetThisManAFez]

@viakth8 As he says beforehand, the light decreases in speed as it passes through the water, and when he says the electron moves faster than light, he means the light in the water. Special Relativity states that objects cannot move faster than the speed of light within a vacuum

[direghostman]

@GetThisManAFez special relativity only state light moves at the same speed no matter what the frame of reference, not that things slow before they hit light-speed.

[GetThisManAFez]

@direghostman I'm aware that light itself travels at the same speed no matter what, just in terms of the question I thought it was easier to explain in the way I did.

[iamgig9876]

@viakth8 its not moving faster than light light is bouncing of, look at their distances covered over time, not displacement.

[gavincfc]

@viakth8 faster in water....not vaster in vacuum

[Nitrozzy7]

"Cherenkov Radiation" = Flash Light.

[sugarwarlock]

Do they sparkle?

[SsCardenal]

Ok, so I learned that Neutrinos are hard to see.. but seriously, what are they

[thachthewandererable]

@SsCardenal they are subatomic particles. They can't be seen as said in the video because they don't interact with light.

[pettrie]

Didn't the news yesterday say no particles can travel faster than light? Something about an error in measuring time i think.

[thachthewandererable]

@pettrie They actually tested this over and over again, and it is proven that it travels faster than light. Now, people think of neutrino as "in another dimension" roughly. We now think that objects that travel below the speed of light cannot accelerate to the speed of light, however objects that travel fast the speed of light cannot be slower than the speed of light. Which is crazy and hard to explain.

[CommanderOrion732]

@thachthewandererable No, they disproved this experiment. Neutrinos do not travel faster than the speed of light. There was an error with the timing of the experiment. When they measured the distance and start/end times of the neutrinos, they forgot to take relativity into consideration, thus skewing the results and making it appear as the neutrinos had gone faster than the speed of light, when really it was human error.

[thachthewandererable]

@CommanderOrion732 no, they have not disproved this experiment yet. They are just saying that the results of this experiment might not be reliable. This experiment has been tested twice, and even the group tested it(Opera) was saying that there might be a problem with the equipment that they were testing with, they are gonna test it again this May.

[CommanderOrion732]

@thachthewandererable The timing error due to relativity was exactly equal to the results they got. The likelihood of this experiment succeeding is extremely low, even when they accurately calibrate all their machinery. (And by succeeding I mean detecting FTL neutrinos).

[oreroe]

photons are literally nothing - they don't have any mass

[ThePlatoon4]

@oreroe yet they exist, mind blowing stuff huh :)

[TheDigitalStone]

@oreroe Photons are causing all electromagnetic radiation. Therefore they are actually something.

They also have mass. Otherwise a black hole wouldn't carry that name.

Please don't spew out nonsense, because some people will believe you.

[CommanderOrion732]

@TheDigitalStone No, photons do not have mass. If they did, they would not be able to go the speed of light. Black holes are able to stop photons not because of gravitational attraction but because of the bending of space-time. Remember, in physics, gravity doesn't exist quite as Newton put it. It's actually a curving of space-time, not a regular force.

[TheDigitalStone]

@CommanderOrion732 Oh no, you're right... i feel like such an ass right now :S

[27duuude1]

If neutrinos have less mass than photons then wouldn't it be obvious that they would be able to travel faster than the speed of light?

[PremiumZero]

then what is Antineutrinos?

[pumpkinpitchy]

@PremiumZero werewolves of physics.

[PremiumZero]

@pumpkinpitchy hahahahaahah. u made my day.

[didgeboy287]

Neutrinos, the glowing vampires that don't make me ill

[ivlfounder]

What's a Neutrino?

Slower than the speed of light.

[666FLiP666]

What do me and a Neutrino have in common?

We're both constantly penetrating your mom!

[dayton3200]

@666FLiP666 you also cant be seen...

[CogitoErgoCogitoSum]

I would like to know how you make these videos. And whats an anti-neutrino? What do you mean by not having its mirror image?

[xrudra4everx]

Wow.

[CookieMonsterNoVeggi]

heavy stuff, dood. heavy stuff.

[ShygirlBieber112]

Dafuq? All I heard was balloons and vampires.

[ajravinath]

Maan talk a little slower! BTW does mirror image mean the "anti" version ?

[RBuckminsterFuller]

@ajravinath "Mirror image" refers to the spin of the particle. You should ignore that part of the video though, it hasn't been settled yet whether or not it has a right-handed equivalent.

[svnhddbst]

you are my new favorite youtuber

[MrSplodez]

0:14 Dalek o.o?

[terancetsang]

I saw the mysterious cat at 0:24!!!

[kaderoder]

So let me see if i got this.. In order to stop a neutrino vampire one need's a large lead stake?

[RadialSeeker113]

i watch the vids for the 'social network' voice and the super fast drawings

thumbs up if u like the vids bcause they make u feel smart

.....or dumb

[RadialSeeker113]

stupid vampires!!

[snacklish]

I love science this is so interesting.

[craZAX42]

so vampires are left handed?

[Ladiciuston]

other side of neutrinos there is in an alternate universe

[RafaellaszBill]

what

[tankie89]

no wrong! right answer: GOD (i joke of course)

[BingBoingProductions]

Was that a Dalek?

[VisCreed]

Doubleyou.Tee.Eff

[AluminumKnuckles]

Now I have more questions.

[mufc4everch]

This stuff is cool until you have to do the math in class...then its even cooler!

But seriously the math is a bitch...

[MrWhateverthenameis]

i've always liked the cat.. somehow the video isn't complete without the cat.. :p

[whupdup]

What i learned: neutrinos are vampires, but still not as gay as twilight

[icanfinallybreathe]

music sounds like from blue's clues don't you think

[sanketnerlikar]

dude r u jesse eisenberg???

coz u sound like him !!!

[joshstyle123]

I'm left handed too,i don't have a mirror image. OH NO!!!!

but more importantly,I'm a freaking vampire

[rakunku]

@joshstyle123 you'd better die!

[Mrw0fflez]

FUCK YOU ADDS, I WANT TO LEAIRN

[katnissevergreen101]

can you be my physics teacher at school???

[TheOiass]

please explain why the neutrino's mirrored image does not exist in another video or our brains will experience some falat err000 404 not found....

[foriegnbroishi]

0:54 universe, upside down, & inverted is univerxe

[chocobosROK]

What I learned: Neutrinos are vampires.

[TheAllimania]

@chocobosROK not as gay as twilight

[GnarlyNewEngland]

@chocobosROK And because of that you'll never forget that they have no mirror image. This guy is great.

[tabaks]

@chocobosROK You have a diminished capacity for learning. You are a...vampire to food of science.

[jacobhackim]

When he said the universe isn't like its mirror image if you look at the reversed word it says "Univerxe". Clever, sir. Clever.

[ignikiX]

If neutrinos -> vampires...do they sparkle?

[wiljam64]

So left handed people are vampires?

[Arle1314]

Neutrinos and I have something in common... Left handedness.

[TheSwamper]

I understood everything until the last sentence.

[newlyrisen]

@TheFatmerril its like the schroedinger cat..

But if it really is, and we didn't open the box yet, we would technically be both, non-existant and existant.. Or what? Should we open the box?

[TheFatmerrill]

@newlyrisen we should do neither, who says the cat even exists, we should just play basketball

[DopyMcDoperson]

watched this about 10 times. still dont know what a neutrino is.

[livedandletdie]

Ok properties of Neutrinos They weigh more than electrons are bigger than electrons have no charge just like neutrons have 1/2 spin have near 0 mass. But In the video I watched there was no explanation of which neutrino it was. ElectronNeutrino MuonNeutrino Or TauNeutrino?

Sure I know as little about them as someone not in the field of particle physics.

[tomtomsatnav666]

@livedandletdie Neutrinos are smaller than electrons in fact, and have no charge, and a mass of only a few electron volts, which is incredibly small. Neutrinos come in "Flavours", and different types of neutrinos are suspected to have different masses, although the main noticeable difference between different types of neutrino is their interactions with other particles. Electron Neutrinos tend to be the most common, as they are produced from electron interactions, which are more common than

[tomtomsatnav666]

@tomtomsatnav666 Muon or Tau interactions, since Muons and Taus, which are other types of particle, are very unstable and tend to decay into electrons.

Yay for particle physics ;D

[HeavensBurn]

Wait if all neutrino's are left handed, wouldn't there "Mirror Image" be right handed...?

[dadope20202]

@HeavensBurn They don't have a mirror image.

[mathfeel]

@HeavensBurn Yes and right-handed neutrino doesn't exist. If the universe is symmetric under mirror reflection, then there should be both type.

[zelodec]

can u explain this in a easier way, please?

[Theotherone12321]

how thick does the lead have to be to stop a neutrino? two years...

[williamjpiano]

Neutrinos do not get stopped by 2 light years of lead, 1 light year of lead absorbs half of the neutrinos (its like half life). Likewise 2 inches of lead only stop half of nuclear radiation.

[Enizagama]

Is it me or did I get more confused about something I knew nothing about?

But somehow, I still like these videos...

[ikanhazw1n]

so when the electron goes faster than light it makes the light equivalent of a sonic boom which of course is the sonic rainboom. Electrons=Rainbow Dash.

[ricktbdgc]

i heard a different video about neutrinos that said they would travel through 4 light years of lead before stopping, almost double what is stated here

[schnapps77]

Anyone else get the Dr. Who reference with the bullet (from a Dalek) into a butterfly net?!?  Awesome!!

[BrianDopeFresh]

If time stops at the speed of light, does that mean neutrinos are time travelling?

[thejuicyhamburger]

@BrianDopeFresh if u think of it like that then light is time traveling...

[bencobbrocks]

@BrianDopeFresh yes it does. technically anything going faster than light flows backwards in time and can only interact with sublight matter or energy instantaneously.

[MyStuff774]

I understud everything. Educate yourself and you will understand too

[Thebrowntown1234]

@MyStuff774 you can't even spell 'understood', i highly doubt you picked up on everything.

[The4biddenTopic]

me no understand :s

[TheRedstoneFTW]

1:00 I tryed holding a nuklear explosion in my hands... can you guess what happened?... I took an arrow to the knee, now I'm a guard! :D

[warkriss]

What I learned from this video: neutrinos are the vampires of physics

[MultiEclipse123]

/watch?v=Bp8S8eJkMW8 Herpa derp.

[CKDindustry]

Let me guess...neutrinos glitter under the sun

[GamerAzoonux]

@CKDindustry Glitter from the sun would be more accurate. (Neutrinos are formed during the nuclear fusion that is happening on the sun. Though you wouldn't be able to see them, because they don't interact electromagnetically)

[ThePeanutbutterbunny]

@CKDindustry Wrong, vampires don't sparkle.

[pastordisastor]

@CKDindustry nope, they don't react with light :)

[beastdude]

so wait, electrons can go faster than the speed of light?

[elsantodel90]

@beastdude I believe they can go faster than *the speed of light WHEN SLOWED DOWN in water*. Not faster than the speed of light in vacuum ( the c in e = mc^2 )

[beastdude]

@elsantodel90 ah,yeah, somehow i overlooked that part.

[Aresman70]

Great. Now there's going to be a neutrino version of Twilight...

[Zylarlander]

@Aresman70 Vampires that you can't see, can't catch, and sparkle in water? xD

[azndevil665]

@Aresman70 yeah, but at least they don't sparkle

[BetterStaySneaky]

0:12 Is that a dalek??

[wearexiv]

thumbs up if you thought at the "catching a bullet with a butterfly net" part, the thing on the right looked like a dalek.

[nisbahmumtaz909]

But...

Why do they have irreversible factors?

Hmm. Google time, bitches.

[bacamd]

Can you derive e=mc^2? Thanks!

[mrtoastystudio]

@bacamd energy= e

mass= m

speed of light=c so...

energy= mass multiplied by the speed of light e= mc^2

[gentel916]

@mrtoastystudio u forgot the power off 2

[sethboy66]

@mrtoastystudio Lol, you need to add the precise measurements of each of those expressions in order for any of that to make sense.

M=mass in kgs

E=energy measured in joules

C= speed of light which is universally constant as explained in this equation itself.

I have fixed you mistakes, you are welcome.

[MaDaFaKaSsS]

what do i have in common with a neutrino?

we are both penetrating your mum

[hungrymormon]

i like the cat :3



[TrampVamp]

Light goes slower through water?! I thought it was a calibrated speed

[NERD9054]

I wish I enjoyed Physics in school more than I do, because on YouTube, it's much more interesting and fun!

[MrBaldenegro]

Actually, it's better to say that the neutrino is its own anti-particle.

[olesto]

what

[OLH064]

0:31 :)

[dragooner4]

Einstein may have been wrong we don't know, but it doesn't necessarily disprove E=mc^2 because photons still interact with every force, while neutrinos don't, so unlike photons, which are bound by all the forces, a photon must travel in a wave, while neutrinos just travel in a line, and the shortest distance between 2 points is a line, making a neutrino faster than light.

[MrBaldenegro]

@dragooner4 Every particle behaves as a wave, Dragooner.

[bartho7]

Univerxe?



[tomroylance]

@bartho7 (Not the same as it's mirror image)

[43darkNero]

dude if they harvest the energy then we can get to the 2nd earth :D

[TheQuantumNova]

MIND... BLOWN....

[TheFatmerrill]

physics is gonna go to far one day and find out that we dont actually exist,then we'll disappear or something

[Theotherone12321]

@TheFatmerrill according to my studies we don't actually egraeoierah'A{uTRDAWR2

[TheFatmerrill]

@Theotherone12321 i would like to know more about your studies
