The Tides

[purpledude2]

I just watched a bunch of these and now I feel smart.

[Disneywomen101]

the moon kinda looks like a bowling ball

[MrCaindude]

so this would mean that im lighter when the moon is over head(night) cool

[cbprice25]

BAD TIDINGS.

[ideedkindsir]

The guy is smart enough to figure life out, but not to use a whiteboard instead of paper and save trees...

[William0diver]

The year you gave is after it is thought that the earth will be engulfed by the sun when it goes red giant. by 100's of billions of years.

[thebackyardmovies]

1:23 one problem the moon is moving away

[didgeboy287]

That was a pretty simple explanation, possibly the first that simple on these videos. I'm glad God made smart people. :)

[xXKlasforXx]

@Maximumdistance and your mom who has a bigger hole does too

[musicismylife816]

Why is the moon a bowling ball??

[PBP113]

y are u spraying water at a sheep ? :s

[theskadudeguy]

about black holes: you cant tell that you would be ripped apart. because its lightyears of space folded into one place. if you put your hand into a black hole your hand would instantly exist in the middle and the end of the black hole before your elbow reached the black hole. So you would be stretched across the entire thing and the rest of your body would probably follow

[Dannyowen555]

@theskadudeguy Actually, you'd be ripped literally apart before you even reached the event horizon of the black hole. You'd definitely know about it.

[HamsterAtDawn]

I see what you did at the end there.

[daredog9]

very punny...

[TheRepublicOfUngeria]

But, Bill O'Reilly said you can't explain this!!!

[Sharlock93]

Spaghettification: the death by a black hole

[thgirwjt]

this just blew my mind.

[fearguyQ]

Lol...the penny

[adamdabadboy]

I love how dangerously close this was to two minute physics

[adgsTV]

@adamdabadboy Five minute physics. /watch?v=XwaGW-x7hS0

[Fettsack63]

you, sir, earned a subscription.

[Player99999ERROR]

the moon is actually getting further away every year (vsauce) 3.7cm a year

so the moon will NEVER get ripped apart coz of the earth (in your theory / may be possibale one day... other reason though)

[rasheedlewis1]

@Player99999ERROR vsauce army UNITE!

[surf4less]

@Player99999ERROR unless the moon takes a direct hit from a comet (ala 2012) which shoves its orbit closer to earth

[lion95805]

i actually just knew that the crust also bulge ._.

[thejakel11225]

But isn't the moon slowly drifting away from us? how will the moon disintegrate from tidal forces when it will eventually drift away from the earth?

[lion95805]

@thejakel11225 he said IF the moon is a little closer to us.. :)

[roarbear998]

he always uses a sheep as example..

[gorillazhead]

I honestly believe within the next 2000 or so years, humankind will become extinct.

[Pjetar]

0:14 Using money to draw circles is cheating. :D

[Boredpersons55]

Sloshing and bulging...getting pretty hot in here.

[TheScottygriff]

wait who sprays water on a sheep?

[Broskisproductions95]

@TheScottygriff The Irish. =P

[Imabadspeller]

hee hee, thats pretty punny

[LEGOmations0091]

So that's why my house creaks at night...

[thedingdingboys101]

i didnt know u where a lefty

[narutokage777]

Tide goes in, tide goes out, you can't expl.. wait, what?!

[Symplyst]

Why was I not subscribed to this earlier?

[decdec1234]

this is dangerously close to 2 minute physics...

[GherebenR]

You CAN explain that. XD

[TheHardcore4u]

@GherebenR u don't have to understand to vote up, just like the rest of them did lol

[GherebenR]

@TheHardcore4u ummm ... I was making a reference to the Bill O'Reilly You Can't Explain That Meme (“Tide goes in, tide goes out. Never a miscommunication. You can’t explain that,” - Bill O'Reilly)... I do understand what he's talking about ... nvm ... :|

[manamesjohn]

great job on scaring me shitless.

[iugey]

I don't believe you minute physics, I could fly a spaceship through a black hole safely if I felt like it.

[iugey]

0:13 Quarter!

[JrDarkPhantom]

i don't get how the water from the other side of the earth (not the side facing the moon), gets pulled away from the surface of the earth if the pull is towards the moon which is in the exact opposite direction! someone who understands pls help.

[biwinning2013]

@JrDarkPhantom So basically the side closer to the moon is getting pulled by the moon, and the other side is being "let go" a little bit. Does that make sense? Gravity can't pull as hard on that side because it's so far away, and so that side is "let go."

That's oversimplified a lot, but do you get it? It's a hard concept.

[hectorbector11]

@JrDarkPhantom The far side of the earth is falling away from the moon due to centrifugal force, and the close side is being pulled due to the moon's gravity.

[Nilguiri]

@JrDarkPhantom

The important thing to realize is that the earth and moon revolve around the centre of mass of the whole system (barycentre) which is not right in the centre of the earth, but slightly towards the moon, like a spinning hammer thrower.

The water on the side nearest the moon gets pulled towards it because it is closer and gravity wins whereas the water on the far side is further away so gravity loses and it flies off into space a bit, like sweat off the hammer thrower's back would.

[Satlam]

I find gravity attractive.

[colebarclay]

Best. Channel. Ever.

[aX3iDenT]

I did this in physics today!

[ThouShaltNotComment]

Right..

[MrKoontar]

the moon is actually moving 33mm away from earth a year

[KingofNewAnglia]

I have for a fact the Moon is actually getting further away from Earth at a rate of roughly 3cm a year...

[ShiftConttrol]

What does the sheep have to do with anything, it could've been anything but it had to be a sheep.

[jjlohsna]

0:04 so the earth isn't round, but rounded?

[PYates77]

@jjlohsna Nope, the earth isn't perfectly round.... :O

[Pencilskickass]

The guy keeps changing from right handed to left handed throughout the playlist. hmm.

[Manganization]

I laughed so hard when you said the moon would shatter. I know it's serious but it was so unexpected. With this I hereby subscribe to you.

[CovertJazz]

Ooooh. a little spaghettification at the end there!

[globalarte]

"Tide goes in tide goes out never miscommunication...you can't explain that".

Bill O'Reilly.

watch video: Bill O'Reilly v. Dave Silverman - You KNOW they're all SCAMS!

watch?v=2BCipg71LbI

[Lucassandro25]

@globalarte haha right, when i saw the title of the video in the suggestions i immediatly thought of Bill o Reilly's stupid phrase about tides....

[flowiepanda]

I like how you draw an awkward earth circle in the beginning and then decide to use a quarter the next time you draw the earth xD

[mynamemattersnot4]

Wow the moon will make for some very short years if the Earth is gone by then. :P

[Hinduspy]

tides go in, tides go out.

CHECKMATE ATHEISTS

[HotXingVG]

@Hinduspy Story book written, people worship it. Seeeemmmsss legit?

[Shmulye]

@Hinduspy LOOOOOL

[LoLSeba432]

@Hinduspy Wtf!? Explain please.

[baguetteman69]

@LoLSeba432 type Bill O'Reilly vs Richard Dawkins on youtube

[johtohoennfan45]

@Hinduspy That proves nothing. He just described how that happens. It's like saying "People cook food, they eat food. CHECKMATE ATHEISTS." It makes no sense. The tides could turn into flesh-eating monsters, but they don't.(some) People spend good amounts of time making food to eat, but do they somehow acquire money to launch it into space and do so? NO.

[Aldridge517]

@Hinduspy LMAO

[supermecis]

Luckily the moon is moving away from earth and won't come back any closer !

[AwsomeLorenzo]

Now if we can only make an equation in which my teacher gets subtracted and you get added.

[DudeOfBordomXD]

Haha... well, hopefully that won't happen because of dark energy? And everything moves away from each oth... yeah, we're fucked.

[Bulasz]

So why exactly is there a high tide when the moon is exactly below your feet? Because it's the furthest and therefore the gravity the lowest?

[Shmior]

@Bulasz yes, the moon pulls more on the center of the earth below your feet than it does on the water around your feet

[WNxFish]

Slight correction- the tides are slightly off from when the Moon is directly overhead and directly behind you. It lags a bit because the Earth's spin pulls it away. This is also the real reason why the Earth slows down- the friction of the tides being pulled out of perfect alignment with the moon. The Moon's rotational period is no linger being slowed down by the Earth because, as it's now in alignment, there is not nearly as much friction.

[darkmaster489]

mmmmm bulging and sloshing

[dragonflame172]

Lol, say you are spraying water at sheep? Who does that?

[Nintony58]

UGH! ......that pun... it... that was horrible

[PrimeTimePotato]

so chinese new year will finally be on the same day every year in 27000000000 years time?



[Zadius895]

@PrimeTimePotato No, in a few billion years, the Earth will freeze, as it cools a few degrees every year. So we won't get there.

[MrVaddiReddy]

@Zadius895 No.. the earth will burn in a few billion years as the sun expands or either turn into Venus before that if we keep up our burning on fossil fuels. Anyway im pretty sure the human race will be either dead or have left the planet before a billion years...

[PrimeTimePotato]

@MrVaddiReddy no, i'm pretty sure in 246,889 years time the earth will get invaded by badger molesting aliens. Which in turns causes an uprising of intelligent mutant badgers, that will start a global nuclear war. This war shall consume the world and mutant badgers will be the next dominant species, until the rise of the apes.

[MrVaddiReddy]

@PrimeTimePotato True dat.

[daviddaaannggg]

First thing I thought of when watching this was Bill O'Reilly needs to see it. presented in the most simple form possible and he'd still be arrogant enough to dismiss it

[anthonimorrow834]

Why sheep?....

[CrazyMegaOmega]

except by the the year 270,000,000,000 the earth will already have been disintegrated in the inferno of our sun when it expands to its massive state in about 5,000,000,000 years

[morethananobody]

Does that mean if the Earth and Moon rotate at the same speed one side of the Earth will always be night and one side will always be day?

[Miemietheron]

@morethananobody No. If they rotate at the same speed you will always see the moon at the same place, and the same side.

BUT day and night is governed by the sun. So it will only be one side day-one side night if the earth doesn't rotate at all.

(Also, even if the earth and moon rotate at the same speed, you will still see different phases of the moon as the entire earth-moon system still rotates around the sun)

[BloodBronze108]

sheep!

[seandunn24]

When do gravitational tides forces cause the moon rocks to fly off of the moon's surface?

[MisterRedstone]

"Tide goes in, tide goes out, you cant explain that" -Bill O-Reilly

Suck it Bill. Suck it.

[UmmIhsanAhmed]

@MisterRedstone hahahahahah Nearly peed my pants "Never a miscommunication" Shyah, always a non-sequitur, Bill O'Reilly.........

[rorag111]

hey could you do a video on black holes? that would be really cool thanks

[thanatos454]

Never a miscommunication...

[RedSkyNord]

i wish i had illustrations like these as my thoughts.

[AngryJackC]

Beware the Tides of March!

[BamfIamone]

BAD TIDINGS AHAH nicccce

[GDJTMZMJK]

i like this channel

[HerpDerpBeehive]

Take that! Bill O'reilly!

[Varoonmg]

@HerpDerpBeehive Yep...:))

[chivasillars]

You can't explain that.

[CoolCat123450]

Well, if the moon does goes inside the Roche Limit and disintegrates due to tidal forces from the Earth exceeding the moon's gravitational equilibrium, won't it form rings due to varying orbital forces?

[kevin1996lee]

Studing for my science test... Done

[Mobeh1]

Dude, king of the web. NAO

[bloodypirates247]

Bad TIDE-ings! Ahahah, I see what you did thar!

LET ME SEX YOUR BRAIN <3

[mrdejavu96]

THUMBS UP IF YOU CAN ACTUALLY UNDERSTAND THIS VIDEO.

[budperson]

@mrdejavu96 I FEEL SMART CAPS LOCK IS CRUISE CONTROL FOR COOL

[XionixZTV]

@mrdejavu96 I'm 14 and I understand this... so basically all you are asking is to thumb up your comment -_-

[GodlessHippie]

a two minute 'minutephysics' video?

you can't explain that!

[islandgirl5311]

@GodlessHippie aculey its 1:59 not 2:00

[AlfaFRONDZ]

Well... FUCK

[MrSpaceman8774]

bill o reily didnt know this

[AKShamu28]

0:35 turn on CC... flamingo...

[TheKlink]

Isn't the moon's orbit getting thurther away from us?

[fantasgasmic]

OOOH, a bicentenial anniversary quarter. NICE.

[holyhelo5speak]

wrong on the last part... if you go into a black hole, its only "predicted" that you would be spaghettified. its a word scientists came up with to explain how your feet, that are closer to the center of the black hole, get sucked in much faster than your head, which is further. the gravity would be strong enough to turn your body into string, but it must be an extremely fast process.

[MacksP0w3r]

Tides: You can't explain them.

[Awesomeness1910]

@MacksP0w3r aliens

[SuperHappyNoodle]

i <3 quarters

[mediawolf1]

OK, I want to make sure I understand this. So...

I weigh the same during a solar eclipse as I do during a lunar eclipse.

And I weigh the same if said eclipse happens at noon, or at midnight.

But, I weigh more if it happens at 6am or 6pm.

Is that correct?

Thanks.

p.s. How big is the difference? How much more/less would I weigh?

[dazzleey]

think m gettin sumwhere... naah nothin.. :P

[azizborashed]

poor little sheep

[kdum8]

I still don't understand why there are two tidal bulges, one facing the moon and one facing away. What causes the second bulge, can anyone explain clearly?

[mediawolf1]

@kdum8, when the moon is overhead, it's pulling the water away from the Earth.

When the moon is directly below, it's pulling the Earth away from the water.

In the latter case, the Earth's center-of-gravity is closer to the moon than the ocean.

So if you stop the video at 20 seconds...

The ocean on the left is pulled toward the left the most (big arrow)

The Earth is pulled toward the left somewhat less (middle arrow)

The oceans on the right are pulled left-ward the least (small arrow)

[lambdaofbacon]

@kdum8

There are several factors, but the one that makes the most sense to me, which is not the way that is explained in the video.

1)Water wants to fly off the Earth's surface because of the Earth's spin.

2)The moon pulls water from the close side as well as the sides to create the near high tide.

3)The far high tide is due to moon's gravity not being strong enough to affect it. It is due entirely to the water being slung off the Earth, which is why it isn't as tall.

You can physics this.

[JeguePerneta]

@lambdaofbacon Great anwser, i wasn't getting what was going on with the two tides until your post =p

[lambdaofbacon]

@JeguePerneta

Well thank you. Like I said, there are several factors but this is a simple and fairly accurate model. You can actually derive this happening using point sources for gravity and checking what happens at each individual point of water. When I saw the derivation, that's when it clicked for me.

[KANMANDE]

@peterhejlejensen LOL

[zink220]

so ur saying we should blow up the moon?

[vitaminsandstds]

How'd the moon get there? How'd it get there?

[notexactlyIO]

Are you claiming that the moon PULLS THE EARTH AWAY FROM ITS WATER? That is very hard to believe! That would imply that the Earth is being pulled around by the Moon! This makes more sense: the Earth-Moon system rotates around its center of mass, which is somewhere between their individual centers of mass (closer to Earth). In other words, the Earth and Moon both orbit this collective center of mass. Therefore, it is centrifugal force that causes the high tide on the side opposite the moon.

[MadeOfCATS]

@notexactlyIO ... I'm not sure if this is trolling or really clever trolling

[00ipodboqi00]

[theory816]

does anyone know how he makes these videos???

[stunning480]

i watch becuz of his awesome drawings even though i dont understand anything

[sowbelIy]

@stunning480 that's sad

[StojanSR]

Damn, I love this guy!

[makro80]

WAAAIT, I have a question; The moon isn't rotating at all?

[ADG2988]

@makro80 It is rotating but at specific rate that allows one face to always point towards the Earth. This may be hard to visualize in your mind so a handy trick is to use two common objects. A dinner plate can be the earth and a coffee mug can be the moon. Imagine the handle side is the side we can see. The mug has to revolve around the plate AND rotate as it revolves in order to always show the plate the handle side. *notice what happens if you stop rotation and don't twist your wrist.

[ferrous719]

@makro80 it makes one rotation per month. it is 'tidally locked' to us, the same way mercury is tidally locked to the sun- mercury has a 'year' that is one long day.

That's not a moon, that's a floating bowling ball

[flh618]

why a sheep?

@flh618 haha that exactly what i was thinking XD

i came to see if u r lefty :D

[scottste006]

U mean to sheep

[MikalMirkas]

So what you're saying is Majora's Mask is a lie D:

[DeathnoteBB]

@MikalMirkas if you've beaten the game you'd know science doesn't count on that part

[MikalMirkas]

@DeathnoteBB I don't care ;-;

[TheQuietcount]

Does the gravity have the same effect on the atmosphere?. Does the moon have an effect on the earths magnetic field?.

[slicer432]

I saw the coin at 0:14 :P

[Steven23490]

@slicer432 who cares?

[RawrMeansIDontLoveU]

I love how this was so dangerously close to being twominutephysics. XD

[mattolsten]

please please explain how wind is created/formed ive alwased wondered that and i think you could explain it cery well:)

[BringerZan]

@mattolsten Okay the wind is created by the uneven heating by the Sun on the Earth :)

[DJayye]

@lightmobile Read that article again, it doesn't refute the claim that gravitational but states it is the greatest force. Your statement is incorrect as if angular momentum was the cause of far side low tides, it would also act onthe close side, negating the other tide. It's also incorrect as gravity is not constant, therefore the force acting on the farside is far weaker, therefore allowing the water there to heap.

[TheDarkluster69]

Please do one about kinetic energy I the basic but i get awful confused.
