  • mt engraçado!!! carak! a ciencia pode ser engraçada!

  • Mooiedromen klinkt meer als en nachtmerrie!

  • Dr.De Grasse is so smart... Mooiedromen what degree do you have ? If any. Don't hate.

  • this guy is always so full of s.. is he getting paid for this or his stupid time machine.

  • AHA according to physics if there were nothing else in the universe other than earth and you shot something hard enough to leave earth it would always come back as long as it does not have a constant force. so if it had only an initial force that got it away from the earth it would eventually come back no matter what.

  • @FenixLites I thought that was his point.

  • @FenixLites Too bad that hypothetical premise can never be met.

  • "If you die this way, you won't get to tell anyone how you died." Really? Well shit...

  • YES.i talked about that subject with a friend a while back and it turns out we were right.

  • It's not true that nothing escapes a black hole.Hawking radiation does.

  • @Thorrr333 Hawking radiation doesn't exist in a black hole. It exists just outside the event horizon so it isn't escaping the black hole.

  • "If you die like this you wont be able to tell anyone how you died"

    I cant do that on earth....

  • @keshaz12 Well, the person who died couldn't, but forensics probably could.

  • I have always wondered if a Black Hole could be detected visually by the same method that we discover planets beyond our solar system... A black hole in a binary system passing in front of a star should change is spectrum and be detectable, shouldn't it? Or would such a system be too rare to detect with current technology.

  • @vickster339 Scientists have discovered a black hole in the middle of our galaxy; by visually seeing huge bodies of mass (stars, and stars that are hundreds of times larger than the sun) orbiting an invisible force at unimaginable speeds - A black hole. But you misunderstand the concept of a black hole; they aren't vacuums that travel and suck up everything in it's path - They are spaces of extreme gravity, where gravity has won it's battle with a star.

  • @unwantedmonkey Any star with a mass greater than the Chandrasekhar limit has no way to stop the iron core collapse from becoming a black hole. Apparently my idea for detection of solar mass black holes was already used in a survey back in 2002. Gravitational microlensing alters a stars brightness/spectrum and was used to discover a few solar mass blackholes. Thanks for putting me in my place.

  • @vickster339

    I'm guessing it would be detected by the visual wobble we see coming from the other star as it's gravity is effected by the BH. That's how we detect exoplanets, so I'm guessing the same would apply for other anomalies.

  • I want to have sex with this man.

  • "Once you go black you can't come back"

  • i thought he meant the one in calcutta....

  • actually, I guess most if not ALL western languages have different words for when you kill, or you are killed, or death by electrocution, etc. Specially if the words have roots in latin or greek, like homicide, for example.

  • Other cool words on how to die: defenestration, decapitation

  • @eclepticearth also words that exist in most other western languages, because they have roots in latin or greek. In portuguese for example: defenestração and decapitação. Defenestration (latin) de- (down or away from) fenestra (window or opening) Decapitation (latin) de- (down or away from) caput, capitis (head) Homicide (latin homicidium) homo (human being) caedere (to cut, kill) by coincidence, the prefix HOMO exists in both Latin and Greek, with DIFFERENT MEANINGS (greek = same)
  • but what neil does not explain and most of the science communty cannot explain, is...what happens to the atoms and particles when they are "digested" by the black hole? Well, the answer is as simple as shooting a bullet. The black hole is a massive quantum accelerator, the atoms and particles are shot into space at unbelivable speeds and they become 3 types: radiation, atomic gas and molecular gas. And this is how galactic relocation works. The universe is a lot older than 13 billion years...

  • @tartupets Cool! Could you message me some links or book titles on where I could learn more about that?

  • @tartupets nonsense. Only a few particles are shot back into the universe, through Hawking radiation. And the proportion decreases as the black hole mass enlargens. Massive black holes shoot much less hawking radiation than they absorb mass, so even after they stoped absorbing mass (because there is none anymore), they will still take trillions of years to dissipate.

  • @rogerpenna

    I would like to know, if this theory is as rock solid as knowing what the black hole is and even my wonky theory. But as unproven as is the mechanism of a black hole, can you over throw my vision on the subject? even, IF black holes absorb mass...it also accelerates particles. Thus, I find black holes to be transitional mechanisms between the macro space and quantum space. Is there a limit, what a black hole can absorb?

  • @tartupets yes, the Hawking Radiation theory is quite solid mathematically and quite accepted by the physics community. The fact black holes accelerate particles means nothing, since the particles are NOT accelerated above the speed of light, and as we know, light cannot escape a black hole.

  • @rogerpenna How do we know that the speed of light IS the highest speed? We cannot see the conditions inside the black hole. Its a whole different dimension. It might have speeds beyond our comprehension. This is actually where the laws of the miniscule come to help us. Quantum physics can explain actually, what happens in a black hole. The speeds in the atomic scale can be greater than the speed of light.

  • @tartupets

    "How do we know that the speed of light IS the highest speed?"

    this is scientific fact. If you dont know physics, then DO NOT question it.

  • @rogerpenna Death is a scientifict fact. A car tire wearing out is a scientifict fact. That does not mean physics should have bounderies. Its what you are saying right here...I should take facts as stone proof and nothing is more that facts we can prove. Limiting the number of ideas we can have, limits the understanding of the world around us...and you are telling me to not question the world around me?

  • @rogerpenna

    theoretically....crossing dimensions is a faster means of transit...if humans had that capability of course

  • @tartupets also, I dont think there is a limit to how much a black hole can absorb. Central Galactic Black Holes may have the mass of billions of stars...

  • I can't remember the last time I saw a black person on youtube that I thought was intelligent and I could actually understand..

  • @G3arJammer

    Neil deGrasse Tyson is the perfect role model to black kids, too bad most of them preffer to take rap singer as role models. Shit, even white kids are taking rap singers as role models nowadays.

    And lets not even mention that all those white hillbillies in the bible belt that believe the universe is 6000 years old

  • brings new meaning to "once you go black..."

  • Black holes ain't gonna let you go back in time.. it will make you go to hell.. because time travel is just impossible.. because what we become today, won't made us live in this very moment if we change our past

  • My cousin was killed by a black hole and this audience offends me.

  • @guyonthebenchful Not to be racist, but it's always the black holes huh? Never hear of white holes killing people.

  • @tanberetO

    Yeah, I know; Black Holes really SUCK.

  • If jigsaw made a black hole trap it would sooooo awsome. don't ask me how he it would be done, but it would be cool.

  • I want to watch him fall into a black hole.

  • @califotec faggot

  • @its9001 lol What? What does my sexuality have to do with anything?

  • @califotec

    I want to watch you fall into a black hole!

    

  • @GuitarMannnnnn Trolls don't fall into black holes, they throw people in. :P *throws you into a black hole and watches you spaghettify as you reach the event horizon* You jelly? *trollface*

  • @califotec

    Ok, fine, fine you win. But if you're close enough to throw me in, you probably can't escape the gravitational pull either, thus your own spaghettification is inevitable.

  • i'm just gonna go cry in the corner now.

  • He's brilliant

  • .......soooooo once you go black you aint turning back? :P

  • Comment removed

  • watch out we, we got a bad ass over here...\

  • my science teacher met him he is one of the greatest scientist of this time

  • @tahthedon soul escape?? good question

  • wow i totally understood this. this guy would make a great teacher or professor. wow he is incredible

  • But what happens to the pasta sauce and parmesan cheese? Do they survive to sell to another blackhole?

  • thanks a lot... now i'm afraid of black holes AGAIN <.<

    they are still awesome^^ (but scary)

  • So, if the sun is sucked into a black hole, and it's spagetthified, will it then be cut in 2, then 4 then 8 and so on, and eventually there will be 100 billions of tiny fireballs? :L

  • @HelpfulNut Since the sun is mostly plasma and not solid matter it would be pulled in as a stream rather than snapping, more like "I drink your milkshake." This phenomenon is actually how most black holes are observed, go check it out, it's terrifyingly beautiful.

  • Spaghettification seems like a fun way to die, probably so fast you wouldn't feel it....

  • @Trashcansam123 Wrong, it's one of the most painful deaths you can imagine. It's fast, but not fast enough. It'll last a minute before you eventually die.

  • @NickWaterfall Good thing I'm a masochist.....

  • he said: "if u die this way u wont get to tell anyone how u died"

    so if i die any other way, i will be able to tell people how i died....after im dead???? LOL

  • @s3125694 No but you're body can but not in the case of getting sucked into a black hole

  • @s3125694 LOL

    I think he means that your remains will become so tiny there will be no trace of you.

  • Watch out, we got a badass over here!

  • The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers). But, if you measure the earth through the poles the diameter is a bit shorter - 7,901 miles (12,715.43 km).

    

  • I'm going to name a song Spaghettification

  • My astronomy teacher showed this to us in class.

  • falling into an event horizon would be the best way to go!

  • Wait what is the difference between the force of the stretching and squishing caused by the curvature of space time, because if they are equivalent you will be geometrically similar in ratio to your original size until you become to small and your subatomic structure collapses into energy radiation.

    But if they are not whichever is stronger will do the most damage.

  • @SH10JogaBonito You are stretched length-wise and squeezed width-wise.

  • Neil deGrasse Tyson must be the person I look up to the most. He is a truly inspirational human being. Whenever he talks, you listen, no matter how long he keeps talking, I never lose my attention.

  • *a doctor

  • He needs to come to my school. Teach us about this.

  • he is funny.. and yet a doctor of physics !

  • this guy is brilliant 

  • He said "bifurcate" in a sentence, in contect , he's smarter than me already

  • @Arsolon618 Haha, he's an doctor of Astrophysics who also happens to NOT be boring. I love whenever he's on the History Channel because he's just so damn entertaining! If you have Netflix, look up some of the Nova Science Now documentaries he's done. He makes learning fun.

  • Degrassi been playin too much Mortal kombat lately.

  • Why being snapped at the waist? First thing that would snap would be knees and the rest afterwards!

  • @Shemassault Why the knees first? Ankles come before knees, and toes before ankles.

  • It's black, you fall in, you're not comin' out. Hmm... deGrasse has a dirty mind... XD

  • What about neutrinos?

  • @aimela18 they didn't know about it back then.

  • @aimela18 Neutrinos would be caught as well, I guess. However, the neutrinos would be able to get a bit closer to the black hole and still be able to escape.

  • Cosmic yoga dude!

  • But what if you dive into the black hole head first then your feet should catch up(if your feet will feel a greater gravity) and BAAM you can now live inside a black hole... SUCCESS =D

  • @arkaros0

    Nope (unless you were just trying to be humorous- it's hard to tell tone with only words)... If you watched the video, the reason why your feet would have greater gravity pulling on it is because it is closer to the core (not because our feet are randomly like that). So pretty much you would still get "spaghettified."

  • This proofs the existens of our noodliness the flying spaghetti monster

  • I wanna jump into a black hole now.

  • Maybe on a future 1000 ways to die episode.

  • "It's black, you fall in, you're not coming out, it's a one way trip." Well said.

  • Flying spaghetti monster and spaghettification. Hmm...

    I see a conspiracy! Alert the elders!!

  • @dummychaos May you be touched by His Noodly Appendage.

  • lol speghettification

  • Relationship between Flood of Noah(P.B.U.H.) and Passing by Black Hole

    cuz Black Hole fits perfectly well with the Conditions of Flood of Noah(P.B.U.H.)

    There were Mega Gigantic Tsunamis like Mountains --- Tidal effect of Black Hole

    Water started coming out of Earth in great quantities --- Gravitational Pull of a Black Hole

    i dont know for sure --- thats just my thinking --- any positive feed back --- ??

  • @watup2154

    Nah, man. Gravity can cause floods, sure, but the similarities end there.

  • @watup2154

    This is so stupid and wrong I hope for your own sake you're trolling.

    I'm not even a physicist and can think of 5 reasons why this is so illogical I question whether or not you have autism from even conceiving such a thought.

  • One way trip :o

  • one more time sience proofes that the flying spaghetti monster is the one true god

  • His speech on George Bush is brilliant.

  • "That's a bad situation to be in", LOL. Love the man's humor.

    

  • He gots so much swag it''s crazy

  • When I die, I'm not getting buried- I'm getting spaghettified.

  • he's awesome!

  • this guy made me love science

  • I love Neil

  • Spaghetticide: The act of purposely jumping into a black hole.

  • @rofljelly135 Actually, that would mean killing spaghetti.

  • @rofljelly135 Spaghetticuted. Person sticking a fork into a black hole.

  • @rofljelly135 spaghetticide is the substance used to kill spaghetti (think spermacide). the thing in front of "-cide" usually indicates what will die anyways. Spermicide. Fratricide. Patricide. Infanticide. Homicide.

  • @Davealapoo itwasajoke.avi

  • @rofljelly135 I understand the humour but I thought this would interest you. The suffix '-cide' is used in english to mean murder. Thus, spaghetticide would actually mean: The act of purposefully sending someone into a black hole.

  • @rofljelly135 I know you posted that months ago, but technically spaghetticide would be murdering someone else by spaghettification. Auto-spaghetticide would be suicide by spaghettification.

  • @rofljelly135 I think a bullet will suffice

  • If only my science teachers were like this

  • @mr94hitman People who say that just weren't born to be scientists. It's not your fault, not theirs either.

  • This is what I love about this guy. He explains it in English.

  • If you don't worship the Flying Spaghetti Monster you get spaghettified! That's more "gangsta" than sending you to hell.

  • The way he simplifies extremely complex concepts is a credit to science. Its thanks to people like him that kids become interested in science.

  • Not to mention that according to special relativity time slows down as you are falling through faster than the speed of light... It will seem like ages to you!

  • @orangegold1 Not ages to you, but to any observer. Although the time dilation would be vastly different between varying body parts/positions.

  • @orangegold1 influenztial points it right; it means the poor family members have to watch the victim turn into a stream of subatomic particles... for the rest of their lives. (Or rather, the x-ray emissions that are emitted from the victim's stream as it rotates so fast while being sucked toward the event horizon.)

  • He's like Ricky Gervais of science.

  • 20 people do not understand astrophysics AT ALL !!!

  • So basically being a Midget makes dying in a Black Hole less painful?

  • "the black hole's escape velocity is greater than that of light nigga you get that shit? once you go in you don't come out. it's one way trip dog." - ND Tyson

  • Neil can make _anything_ fascinating. I love listening to him.

  • @myiuer I'd be interested in seeing your sources on that statement.

  • The universe is jacking you off LMAO, in the literal sense.

    

  • Good death metal song.

  • Sounds pleasant o.O

  • Thanks for the nightmare fuel.

  • so is there pain?

  • @mastergradeone Nah, you're dead long before that. Good night, sweet dreams :)

    For a start, your ship gets shredded around you, and you'll suffocate (~10 seconds of awareness, then you pass out and die). Unless you're inside a suit, in which case, man, it's gonna hurt.

  • FUCK You-tube!!! they have an amazing man speaking and have a fucking commercial for that evil "cult: mormons??? WTF You-tube???

  • it exponentially slows down, but it also depends on where you are. If you're the one being spaghettified, then you feel no change, but for someone watching you, they see you slowing down to what seems like an infinite halt.

  • Wait so if the black whole extrudes space-time, and time is being compacted as well, does that mean your extrusion exponentially speeds up or slows down in time?

  • @myiuer Its just a theory... -.- because the black hole lose entropy in theory... LOL xD actually no one knows O_o...

  • @myiuer "Hole" is a bit of a misnomer - a black hole is composed of matter that has been incredibly compressed, known as a singularity. It is called a black hole because, as light (and everything else) cannot escape it, it is invisible and so appears to be a sort of hole in space-time. And matter doesn't fall out of any other side, it becomes compressed into the singularity.

  • where does someone ho when he falls into a black hole?

  • @TranceElevation nowhere, they are simply condensed and compressed into a singularity.

  • rofl he are funny

    Xdddddd

  • you must enter black hole in speed close to speed of light to compensate G force.

  • if u bend space molecules and structures are intact. Problem in this case is G force which must be compensated in this case...

  • I belive everything this man tells.He explains so well!

  • Take the prisoner away and spaghettifi him!

    You'd be scared, does not sound a good way to go!

  • Get the hell off TV and stop dumbing down NOVA

  • "The greatest of 'Black Holes' are NOT found in the outer reaches of a vast and glorious universe. No,no,no! They are found, most interestingly enough and rather pleasantly I might add, in the bus station's men's rooms of our wonderful inner cities."

  • 19 people died in a black hole.

  • Cosmic Yoga :)

  • Once you go black, you never go back. Pun intended.

  • 1:12: "IT'S black" lol

  • I love this guy! So fun to listen to.

  • Can you explain how atoms are formed, how they bind with each other to form molecules, and how the worlds are equilibrated and impeded from colliding with each other???

  • @jqs1943 Atoms go in, molecules come out. You can't explain that!

  • @DarthCannabis Atoms are made by the weave of frequencies. By my theory they can be synthetised. When atoms form some of the frequencies form a electromagnetic field (EMERs) that serve to weave other forming atoms and therefore combine as molecules.

    A gravitational force field has a secondary component that repels other worlds and help to establish their orbital corridors and therefore keeps them from colliding with each other. All worlds have their own orbital corridors. SUNOTICS.

  • neil deGrasse is a deceiver and a liar!

  • In the brilliant "Death by Black Hole", the somewhat priggish author, Neil Tyson, blandly comments (p. 343) about life after the Big Bang: "...one second of time has passed [and] the universe has grown to a few light-years across...". Proving that all the sarcasm and sneering of the book masks the blindness of cosmology: if the universe -- and all its dark energy, hadrons and quarks -- can expand by light-years in one second, obviously the speed of light ("C") is not constant...

  • @liveoilfree I never thought about that. Great, now I'm not going to be able to get to sleep tonight.

  • @liveoilfree

    Are you serious? I encourage you and everyone to actually read that passage. You inserted the "[and]" where it does not belong. The two sentences you have incorrectly joined are actually separated as paragraphs in his book. He is NOT saying that the universe has grown a few light-years in one second. Unbelievable....

  • @liveoilfree In General Relativity there are no global coordinate systems in which the laws of physics as we know them work (inertial systems). Coordinate systems can only be made inertial locally, and it is only in inertial coordinates that light appears to travel at a constant speed C. The proper distance between two non-local points in space can increase faster than the speed of light without violating relativity.

  • @liveoilfree The ultimate speed WITHIN our universe is the speed of light "C".

    But obviously, our universe is not expanding inside itself or another universe with a speed limit.

    And the latest research says that expansion seems to be accelerating! You'd better hit eject and punch out,

    'cos you're going down in flames..

  • Undeniable proof of the Flying Spaghetti Monster.

  • i already know what he's saying but the way he explains it is funny !

  • Haha! I love Dr. Tyson, but he fluked on this one. Something travelling at escape velocity (7mp/s) would *not* actually reach the edge of the universe, as the escape velocities for the solar system and the Milky Way are successively higher. It's something like 250 mp/s for the Milky Way, if I remember correctly.

  • @Killersepp Maybe he didn't mean "edge of the universe" literally, just as a metaphor for reaching very very very far into the furthest reaches of our universe :)

  • i think the word for that is 'Fucked"

  • Comment removed

  • ha.
