Black Holes: Tall, Grande, Venti

[meetsouder]

sad thing is, light isnt the fastest thing on the universe anymore. scientists discovered a single atom from this one source (i could not remember) that reached a sensor before light when fired. look it up

@codezeeky in other words, you're a retard. kgotcha

[jimj122345]

Thanks to Major Tom and ground control. Job well done.

When I was sitting in the Movie viewing 20001, I never figured

I would see this happen for real. Brave people made this

happen.Your Harvard Web is doing a better job than NASA

bringing the understanding to the non-experts Jimj122345.

[peakindicator]

Except for black holes are real and terrorists are fake. If we knew more on the subject, we could maybe catch up with the past civilizations, in that, they obviously knew more about the stars than us.

[codezeeky]

stop for 1 min. ask yourself this, do we really need to know all this stuff? 1:37 we can never see a black hole itself and yet we know so much more than we know about terrorist. use your brain people, wouldn't it be better to use the telescope to spot the terrorist and take them out instead of studying something light yrs away for no apparent reason? If it dose happen we would be alive to see it, probly another 2000 yrs generation will be able to study it but not us.

[BillyBoomstick]

A black can only stop feeding if it runs out of gas to do so or it gets flung out of the system by another black hole.

[carlosgonzalez282]

starbuck sizes

[ananiasacts]

If nothing can bounce off a black hole, does that mean it has a negative or at least perfectly zero temperature?

[ilovemydog987]

our black hole in the center of our galexy, the milky way could never harm us. it has stopped feeding, (it is inacctive). However, there has beeen some research done indicating proof that our black hole is starting up again. but still it would be harmless because it is small incomparison to other galexys

[lilmissgigs]

your right about the Milky wave starting up but it will kill us because we adrominon or w.e comes together with the Milky Wave the Gravitational pull will either pull us out of or system or throw us into the centre of the black hole. So either way aren't we screwed?

[ilovemydog987]

i guess yeah haha

not us personally tho.

[jfriday1991]

This is the first time of me hearing this, what are you talking about? I am a physics major working with astrophysics researchers, and this is the first time I have ever heard that a black hole can even 'stop feeding', or even stop and start up again. Can you explain? (I am not being argumentative or demeaning, this just comes as a shock, and would like to know more).

[c1i2a3r4a]

yes you could die

[wengakk95]

spaghettification? weird word.. are we going to be spaghetti's? x]

[horsechick43]

Is there worm holes? Thanks for this video, I enjoyed watching it.

[R10freestyle]

what happnes if u go into a black hole?

[thetacoboy69]

Why dont you go try it, then come back and tell me about it.

[R10freestyle]

hey y dont u shut up

?

[NewLeaderProductions]

he actually has a point... no one knows because no one has tried to enter one as of yet. it is believed through theory that because it is a star collapsing on itself forming an extreme gravitaional power that it would kill us... via to much pressure on our bodies

[bornarydah]

it will kill you befor u even get sucked in couse its so powerfull that your body would rip apart way b4 u even make it in it all the way

[R10freestyle]

oh wow thats amazing thanks :) its good to have information like this

[ilovemydog987]

molocule from molocule...

[jaimebolanosD]

if you go in a black you either go back 200 years in the past or to a nother universe that's what some scientist believe.

[R10freestyle]

thank you for the infomration

[ilovemydog987]

thats complete bull

[ilovemydog987]

mhmm..

[laziestslacker]

i'm pretty sure my astronomy professor told us you'd die from the extreme heat or spaghettification caused by the extreme gravity of black holes.

[TheReasonWhyGuy]

"spaghettification"

What an awesome word, its used to describe the effects that the difference in pull have on mater. The inner side of the object is being pulled harder than the outer side.

Right?

[kenny8331]

@laziestslacker sorry to tell you but your professor doesnt know shit about black holes

[bomexskyline]

no the universe will never be sucked into one big black hole.

[lilpwnige]

the uneverse will be sucked into 1 black hole becuse if light cant excape it neather can planets or stars. its the big bang theory. 2 dust particles joined they became the matter with the most mass and drew everything else in untill it got so dense bam thermal nucular reaction and the matter was spred out. so theretcly the uneverse is geting sucked into he obgect with the most mass. the largest black hole becuse black holes have the highest mass in the uneverse

[inthefade]

except that they have discovered "dark energy", which is actually causing the universe to expand at an accelerating rate.  Wikipedia it.

[cernacerna]

you're wrong, if you mean the "dark material" which we can't see. This materials could explaine how galaxies can stay together in massive groups, because their gravity is not enough to do that.And therefore, the fate of the universe depend of this: if the "dark energy" is enough, the gravity force stop the expansion of the universe and it will collaps on itself, but if not, the expansion will never stop, until the universe will be a dark place, with nothing, only what they call "ghost particles"

[cernacerna]

you can find it in "origin and end of the universe", a book of the astrophysic Margherita Hack. Or maybe you mean something else..I guess is good to exchange information anyway, bye

[j11j11j11j11]

if a black hole is object with such a strong gravitational pull that it sucks everthing into itself, are they constantly growing in mass and diameter? if not, why not? if so, what's to stop the whole milky way from eventually becoming one big black hole? thanks.

[lilpwnige]

The milky way is geting sucked into a black hole and at the same time the black hole sucking in the milky way is geting sucked into a denser black hole. and that prosses repeats itself untill there is no matter left for the black holes to suck up

[j11j11j11j11]

holy cow. really? so there's another black hole somewhere sucking our whole galaxy into it? and then all the matter gets compressed into that black hole and it gets bigger and bigger? so the universe does have a centre then right?--it would be the main black whole.how long will this take? so the whole universe will end up as just a black hole one day?

[lilpwnige]

to answer your question yes. the only problem with that is that a black holes dont grow the matter is spued out the other end. but the time it will take just for that black hole to suck us in will take a very long time. the sun will probably go super nova long befor the galaxy is sucked in.

[j11j11j11j11]

wow. so eventually our whole universe will be sucked in and spewed out the other side, eh? and then the universe will be over and so will all existence? do we know what's on the other side? some other dimension or something?

[lilpwnige]

an other dimension is 1 f the theorys

[j11j11j11j11]

there's an 'other side' somewhere? it's hard to grasp an idea of what another dimension physically is. the matter collected from the black hole's orbit goes to this place?--physically? like if you measured the mass of stuff sucked in it would exceed the mass of the black whole? so it really physically disappears? does it necessarily go somewhere? amazing. do you know a good book about it?

[lilpwnige]

the ammount of matter geting sucked in by a black could not exeed the mass of a black hole becues then the mass of the matter would cause another hole in space time. also when the matter is shot out the other end of the black hole its technicly flying at the speed of light untill a equal or oposite force is acted oppon it. so to answer your question no the mass of a black hole is basicly infin and the matter would be to spread out to = the mass of a black hole

[lilpwnige]

but what do i know im only 12 years old :)

[crazydang42]

Eh, but you know enough to have an opinion, unlike most people I know, at least.

[sasukecursedchidori]

me 2

[lilpwnige]

i think that at a point the gravaty gets so emence that it puts a hole in space-time. and that when this puncture in space-time happens it creats a opposite to the black hole called a white hole that expells all matter geting sucked in by black holes the black and white holes are created by a kid of tube in space-time called a worm hole were the matter spued out by the black hole travles through a a very fast speed untill it is expelled by the white hole

[ChimairaX10]

You are possibly the mosy intelligent pre-teen that has EVER posted a comment on youtube. EVER

[crazydang42]

I think that the heart of a black hole is a hyperdense neutron star, possibly a couple dozen feet in diameter, as I don't think that the fabric of space-time can be pierced, but can get a rediculously dense object to create a larger and deeper dent in it than most objects. If the "singularity" was a hole, would all black holes be the same? How does a single point with no dimensions rotate?

[thehobet]

who here thinka black holes are justs visual consepts.say me.not me!they are real

[smakabitch]

universe is beautiful and scary

[ooStonedAllDayoo]

So much tension here.How about this theory?

Black hole's great, but Asian holes're better, cuz "Me love you long time!"

[kriptonis]

LOL

Brilliant

[MrInitialMan]

The reason light cannot escape a black hole is simple. "Escape velocity" is the speed required to escape an object's gravity. The higher up you go, the lower the speed required.

A black hole is, simply, any body that has an escape velocity greater than the speed of light.

[MrInitialMan]

(Continued)

Black Holes were first postulated in 1783 by geology professor John Michell, who suggested that there were celestial bodies whose escape velocities were so high that any light emmitted would be pulled back. He was ignored because he was a geologist.

[MrInitialMan]

(Continued)

In 1796, Astronomer Pierre-Simon LaPlace suggested that such a celestial body would have to have a diameter 250 times that of the sun. His theory brought black holes into mainstream astronomy for the first time; however his theories were disregarded because it was believed nothing that large could exist.

[zaepali]

yeah ! :) lol

[huwjun]

look @ 3.35 @ the top it looks like a picture ov a woman scary......

[unico]

they spin fast enough to over take light?

where does the speed come from?

oh yeah. do black holes die?

[LordRyokashi]

It has nothing to do with spinning. It's the gravitational pull coming from the enormous density and mass of the black hole.

There is not yet any proof that Black Holes can cease to exist, if it has every happened, it is unlikely it happened during the times humans have existed.

[threadweaver69]

First of all, there is no proof that a white hole has or could ever occur. Every galaxy is formed by the presence of a black hole. Black holes swallow light because their mass is so large in contrast to their volume that the escape velocity exceeds that of light; therefore nothing can a escape the event horizon.

It would be possible to enter the event horizon without being annihilated by UV rays, the black hole would have to have a very large schwartz radius.

[macaireamerica]

Say all u want

[maisboyfriend]

You would get fried by the rays before you got trough to the end. Second, if there was a worm hole existing, it probly wouldnt be stable. Therefor by passing trough the worm hole, all you would do is collaps the black hole. Third, if it was stable, the gravitational pull would still possibly be enormous, stretching you trough the hole and spitting you back out not looking normal. (stretched bones, organs, ect.)

[maisboyfriend]

But if a worm hole did exist, then you would get sucked up by the black hole, pass by the singularity that wouldnt probly exist, and get poped out of the white hole. (Maybe in another demission, or in a different universe). Now even if a worm hole exist it would be very uncomfortable to pass trough. First of all the energy and ultraviolent rays from pass stars would compulse, heating up to ultrablue x-rays or something like that.

[maisboyfriend]

You can't go trough a black hole. When you hit the horizon you get stretched, then you get crushed from the gravitational pull. Thats called hitting the singularity. Now the only way you could go into a black hole and pop out on the other side is when a black hole and a white hole are formed together to make a worm hole. There is basicly NO evidence that a worm hole exist

[maisboyfriend]

lol Light can go around the world 7 times in 1 second...

[TDOJxmen]

great video

[Piscivorus]

I've read that the reason why the cosmic background is pitch black is because the cosmological constant (the rate of expansion of the universe) beyond the cosmic background is equal to or greater than c so we never any light comming from beyond that distance and, since we can never move fast enough to escape the visible universe, the blackness seems infinite. So... (continue below)

[Piscivorus]

(continue from above)

...if the escape velocity of a black hole is equal to or greater than c, it's event horizon should be pitch black just like the cosmic background but it should collaps inward at the speed of light, rather than expand outward like the cosmic background, until it has no measurable volume. It should literally pinch itself off from the rest of the universe, I would think.

[Piscivorus]

If nothing can escape the event horizon of a black hole- not even light, how does all the mass inside the event horizon generate a gravitational field outside of the event horizon?

[gohar06]

at 1.40 the expert says we can detect the light emmited from the event horizon.thats how they can detect it.i mean how.the guy said not even light can escape it!

[gtizzle101]

no he said we can observe it form the light just outside the event horizon plus the accumulation of gas's etc that for an accretion disc and the x-ray jets etc. you can observe it by seeing bodies that orbit it as well

[gtizzle101]

Its very simple your thinking to hard. The only thing the event horizon signifies is the point at which you cannot escape because escape velocity is greater than the speed of light. If you were on the edge of the horizon you would have to travel at the speed of light to escape it but you wouldn't go anywhere.(continue next post)

[gtizzle101]

If you are beyond the event horizon you can escape the gravitational pull which is still there (granted you need to be going near speed of light to escape or even less depending on your distance) Don't think that beyond the event horizon there isn't a graviational feild because remember things orbit black holes and we know that because we can observe it and the reason we can observe it is because it is outside the event horizon. Is this clearing anything for you?

[crazydang42]

No, since light itself can't go fast enough to escape the event horizon.

[gtizzle101]

yes and so what are you getting at with this?

[crazydang42]

You can't leave the event horizon, since the black hole's escape velocity is higher than the speed of light. If you launched a photon to orbit at the event horizon, half in the event horizon, half out, it would orbit the black hole forever, unless it hit something. since the black hole's escape velocity is higher than the speed of light, you can't reach that speed by the laws of physics, so you can't leave.

[gtizzle101]

i understand that but no one is sayin you can escape from within the event horizon

[crazydang42]

Ah, it seems I misplaced my reply. deahhh...

[engelmohr2006]

True because your eyes work on reflections from sectreams of lights that are cast on objecs and projected into the eye that the brain makes since after such so balcks suck up even light they become litratliy invisible because they canot reflect light.

[engelmohr2006]

How could have black holes captured peoples imaginations if they did not know about it that makes no since.

[SchwertSword]

catnip12344 are you black hole? Are you like bitch?Can you take everything in your pussy?

[catnip12344]

black holes are cool SO NO1 GO INTO SPACE U GOT THAT!!!!! the hole is mine mine!!!! AND NO IM AM NOT NUTS

[nethernovas85]

Black holes, like the wave nature of light, were figured out on paper using ridiculously complex equations before evidence of their existence even showed up. Einstein figured out their possibility on paper, but thought such horrific freaks of physics couldn't exist.

[pan5464]

lmao

horrific freaks of physics...oh man priceless!

I think every physicist alive would agree with that term.

[FlareKyuubi]

Everything you're made up of would be transmitted and scattered to any random place in the universe, which means it's faster than the speed of light and can warp you anywhere, that would explain the speed of which can faster than the speed of light, which is inside the black hole, I'm not to sure, but it's just a guess, and you will surely die before you ever enter a black hole. =/

[engelmohr2006]

no it gravity in so powerful that not even light cannot escape them but their is not way it could go beyond the speed of light because light is the ultimate speed limit in the universe this is so because as you aprroch the spped of light and try to acclirate faster your mass would increase infinatly thus you would need a infinate amount of energy to increase faster and since thier is not a infinate amount of energy in the universe going faster then life is completly impossible.

[coolbito]

How do they know light is the fastest thing in the universe? Exactly... they dont...

[WarKrimes]

Actually they do. Its impossible to travel faster than light with out "warping" the fabric of space.

[ColibriMuse]

it moves 180,000 miles per seconds.

you tell me something that's faster than that.

[stonebald22]

Is there another side to black holes? I mean, I guess we don't know, but I was wondering.

Hypotheically...if you could go into one (and get back out again), what would be in there? Is there a bottom to it? I can't make this sound intelligent, so I won't even try, I'm just a bit curious.

[ColibriMuse]

no, actually, its a very intelligent suggestion.

scientists have thought of it before, but not much studying has been done on it.

however, some believe that beyond black holes there a alter universes.....meaning another universe identical to this one with identical people, but some small veriations.

[stonebald22]

Oh, ok. Parallel Universes. Interesting. I don't think I should venture into researching them, hehe. Black holes are enough of an enigma, for me, at the moment :)

[GargantuanAU]

If you go into a black hole you would be stripped back into a sub-atomic state (pieces smaller than atoms) and heated to x-ray temperature. Either you are shot out at the poles of the Black Hole or your matter is slammed into the surface of the black hole to add to it's density. If you could get out again I'd say you'd look pretty fucked up.

If they said tomorrow that they can send a person into the heart of a black hole, would you volunteer?

[stonebald22]

Hehe, I'm thinking no =]

Thanks for letting me know though. I know now =]

[rewireDESTRUCT]

so if nothing can escape the event horizon of a black hole, then why is there a jet stream of gases escaping from both sides of the event plane?

[Hockeygod98]

those jets are not coming from within the event horizon. The mass being pulled into the blackhole rotates around it nearly at the speed of light. The material is trying to rush in so fast that some of the material is "blocked entry" to the event horizon by other matter. Having nowhere else to go, but also having to discharge the energy it has accumulated, it is expelled from the surface. That's what you're seeing

[zxzdimensionzxz1]

why does it have to be a black hole y cant it be a why hole huh huh huh tell me that

[ZIOS76]

any super massive black pussy lol

[TheIbanezHero]

I just find these black holes so interesting lol
