  • Our politicians need to get the head out of their asses and start funding scientific research again. Its a travesty that NASA's funding has been cut as much as it has.

  • My question is, how did the black hole got to the center of the galaxy in the first place?

  • @cyborg578 actually the galaxy formed around the black hole

  • @spikeguy33 Thank you, I have been wondering about that for a while.

  • @cyborg578

    What spikey said

  • Comment removed

  • Dont let this guy host ever again, or fire your writer because some of this isnt even right

  • Good Video!!...

  • 'For centuries'...??

    No.

  • @gorgolyt they were first considered in the 18th centry, thats at least 200 years ago, so yes that was centuries ago

  • @messi996 By who? Give one example.

  • @gorgolyt John Michell and Pierre-Simon Laplace they never went to prove it , just wrote about it, and wondered if it was possible, they never set out to prove they exist. But as the video said, they imaged it, they never truely set to prove they were there

  • @messi996 Although the modern conception of black holes is very different from the reasons why they were speculating them, you have proven me wrong... thank you.

  • is 770 million years after the big bang enough time for stars to form, then die and turn into black holes? that just seems too early to me to be seeing black holes.

  • @Morophin3 Really massive stars have a short lifespan numbering in the millions of years.

  • @Morophin3 remember the bigger the star the fast it will die, that soon after the big bang, all the gas etc would have been close together(compared to now) So stars would form fast, and would be huge in size, this would mean they would ide very fast, so it really wouldnt take a huge amount of time to form black holes.

  • Cool!!

  • Nice!! Very Infomative. Good!!

  • Good!!..

  • This is truly brilliant

  • GREAT!!!! AMAZING!!!! Thumbs up from Germany!!!

  • @greenkonnector ill take one too :)

  • They are beautiful. Little destructive, but beautiful

  • amazing

  • The woman says that we have conclusive evidence of black holes. Then in the this is very likely ... a black hole". Does anyone have any more evidence than these sketchy photographs of light emitted many light years away? I am a skeptic of this evidence. We live in a time of speculation and conjecture. -especially in astronomy. I love Star Trek too, but I would like to see more evidence before anyone says its "conclusive".

  • @FromAcrossTheDesert You have Einstein's theory and if you would search on the internet in the best site's and get member of some site's or you would study fysica (=> a particular piece of the fysica) that studies these things you would get a lot of evidence.

  • @CFRedDemon I assume you are speaking about Einstein's General Theory of Relativity. Karl Schwarzschild and others that follow simply have introduced mathmatical solutions to the equations. Aside from a few blurry photographs, I have not found any evidence.

    The discovery of muons on the Earth's surface was evidence of Einstein's special theory of relativity. I've also seen measurements of stars behind the sun as evidence of the general theory. And black holes... I'll continue to look...

  • @FromAcrossTheDesert In theory a black hole exists, that what i know really sure :P

  • @FromAcrossTheDesert You should watch the special "Black Holes" on the TV series called "How The Universe Works." It provides conclusive evidence that in fact Black Holes are real. Solid evidence has been provided since the 1970s.

  • @FromAcrossTheDesert You think the Moon landing was fake too? Moron.

  • @hardstyle905 No, we have a great deal of photographic evidence as well as eye witness accounts of the moon landing taking place. Other than some mathmatical solutions to the differential equations of the general theory of relativity and a few blurry photographs, I have not seen any evidence. Do you know of any evidence? Please let me know.

  • @hardstyle905 So, there is a great deal of evidence of the moon landing, but I have not seen much evidence of black holes. Some equations and a few blurry photographs is all I know about. Please provide more evidence.

  • @FromAcrossTheDesert Yes, there is evidence: gamma ray bursts.

  • @hardstyle905 THANK YOU! I will try to find more information on the "Gamma ray bursts". Any suggestions to help in my search?

  • @FromAcrossTheDesert The evidence isn't in picture. It's in the math

  • @SuperMrAtheist Math is an abstraction. Math may point to possible anomalies in our universe, but math cannot be used to prove an anomaly. Science presupposes math and logic, and therefore, math cannot be used to prove science. It would be arguing in a circle, and we all know this to be a fallacy.

  • @FromAcrossTheDesert maybe you should look more into that? Math is use to prove science all the time. The string theory was nothing until it was proven possible by math.

  • What if they all merge together billions of years from now and implode and cause another big bang,I didnt see anything saying how long black holes will last

  • @jason64086 Yes, there are tons of books discussing and analyzing the end of black holes. Common prediction is after a trillion trillion years, black holes begin to decay and vaporize. And after 10^42 (million trillion trillion trillion) years, the last black hole will totally vaporize and there you have an absolute emptiness and nothingness. And maybe, another big bang. Universe 2.0

  • @jason64086 Black hole die after awhile.

  • @SuperMrAtheist awhile is a bit of an understatment:P

  • the THE BLACK HOLE is nothing but everything and also everything but nothing!!!

  • The black hole exist , the question is where and why her localisation is a mysterious ! I love the quantic science ! This is the evolution.

  • We should send justin bieber to that black hole and see what happen.

  • black hole ummmmmmm

    easy it recycler

    it continuously swallows matter until it becomes saturated and explodes thereby creating the new galaxy

    thank you

  • black holes created universe. our universe is inside a black hole, in order to create a universe you must have the entire energy of a galaxy, but the question is what was first the galaxy or the black hole?

  • WOW, from 5m50- on ... just wow...

  • Black holes suck.

  • thank you very much, very good video

  • Attractive force cannot be explained. But if gravitation is the result of pressure of ether (EMWs) it explains extra acceleration force between masses, as ether is weakened in them. Taking Pioneer anomaly for example the 8,7x10^-7 anomaly means 0.380-4.646 million m/s^2 force of ether depending on distance. Pressure of ether can be calculated by gravity anomaly and distance between masses, or at black-holes where the gravitational force toward the black-hole equals the pressure of ether.

  • If all the matter in the universe was compressed into a tiny space no larger than the dot on a page where did all the matter in the universe come from? If all the matter in the universe was compressed into a small dot, what caused this to happen? Where did gravity come from that held it together?

  • @iDroid6 Also, in an environment without friction you would have this spinning dot going so fast it would then explode. If this happened, then all of the particles and matter being expelled from this "spinning dot" would all have to spin in the same direction as the dot they exploded from. This is a known law of science, which those who believe in Evolution cannot do away with.

  • @iDroid6 It is known as the Conservation of angular momentum.

    This matter which is said to have created the planets would all need to spin in the same direction as the object it came fromSo therefore, all of the planets should be spinning in the same direction.

    However two of them are not. Venus and Uranus spin backwards.

    Some planets even have moons that not only spin backwards, but travel backward around their planets.

  • The Big Bang theory also ignores the First law of Thermodynamics, which says:

    "matter cannot be created or destroyed" 

  • @iDroid6 actually ... you are wrong ... matter can easily be destroyed (ex: burning fuel)

    Its energy that cant be destroyed, only transferred from one for to an other.

    But also that is assuming that universe we are is a closed system.

    Since we dont know how universe formed, we cant make any assumptions on how the energy could have formed.

    Since if you look at empty space in quantum level, there is matter coming into exists and disappearing. This is theories to be due to quantum fluctuation.

  • Realy amazing Video i love Space and black hole super Thank You

  • nice video ^^

  • Lol I did WakaTakaB!

  • just another piece of crap idea on how the universe was formed pretty stupid Jesus for life!

  • Religious arguments have no place in this video...Harmony people, please.

    On a different note, I'm guessing no one else thought of Muse when they heard him say "Supermassive black hole"?

  • The event horizon is my favorite part!

  • hmm the bigger galaxy bigger the supermassive blackhole . . . maybe because what the blackhole is made out of is what part of galaxy used to be . . . maybe the blackhole can take more of the galaxy because its bigger . . . the hole probably is weak then strong then slowly gets weaker, since it gets weak the bigger the galaxy is the more it takes away from galaxy u think?

  • the time of this video : 9 11

  • @JonThm what are brown dwarfs? And how do you explain quasars?

  • There are no black holes. They are brown giants hidden by gravitational lensing: so obviously non radiant

  • dang !!!

  • Impressive

  • This is so vast and interesting it's beyond any imagination. Also the images and explanation are so well done for easy understanding, that's cool!

  • Very interesting an educational video!

    I've got to show my family.

    Bo Bo  ^ v ^

  • 8 people from the creationist museum disliked this video XD

  • "For centuries, scientists imagined objects so heavy and dense that their gravity might be strong enough to pull anything in" wow i was not aware that the 16th century scientists understood relativity they must have discovered time travel as well.

  • There is no evidence for Black Holes. Sorry. This is simply science propaganda. Establishment doesn't want to admit the plasma physics is the actual driver of the universe.

  • @babajacob Worst comment EVER.

  • @SirGrowalott prove it.

  • @babajacob Well Sir, I am not a scientist, so I can't prove anything, but you should go check out Einstein and Stephen Hawking, I'm sure you'll find your answer with them two genius's.

  • @SirGrowalott There is no actual evidence for black holes, just pretty mathematical formulas. Until someone can tell me why the following statement is wrong, as a scientist, I will stick with the evidence. If 99.99% of the observable universe is plasma then the primary force in shaping of the universe is the electromagnetic force because charged particles (plasma) interact with each through the EM force by a factor of 10 to the 29 power stronger than their interaction due to gravity. Cheers.

  • Well there is nothing unusual about it, that the galaxy is getting bigger, as the hole is going bigger. And also for early Quasars.

  • interesting vid

  • im not an astronomer but i know a place here on earth where black hole was.. anybody who know the answer reply to me to me

  • Ever notice Dr. J's huge Adam's apple??? I'm trying to pay attention to what he says and all i see is that huge thing bobbing up and down lol. great video though

  • Believers in God, search for "religion george carlin". Thanks.

  • @63Hertzi so, like any other atheist, george carlin is one of the gods in your pantheon...... your gods are better than other gods. you're no different than any religious dick you hate so much. it's pathetic.

  • @kmica2008 Haters gonna hate.

  • Maybe I'm just a dummy...but I'm having trouble jumping the gap between the possibility that there are simply..billions of stars near the center of this spinning galaxy M87. lol. No seriously folks..there is plenty of space for ...billions of stars *near the center*.... I'm a physics guy. Can I do the math for these people? Separating 'fiction from facts' is my area of expertise. Perhaps they need a technical adviser? I see so much of these kinds of speculations on the net.

  • @sounddoctorin You would see them if it were stars. Instead what you observe is a very well collimated jet, originating from a BH. These are astronomers, which means physicists, and I don't think they need any advice.

  • @supergiuovane Lol. Well much speculation goes on between the concrete and the assumed. LISTEN ..were you AWARE that these 'wonders' who need 'no advice'... up til what '98 thought that objects that were in the 10,000 LY framework..were actually off by about 40% of that? If they are *THAT* bad at estimating distances so close in...how little can we trust them with even rudimentary questions like 'how far away are the near galaxies'? LOL. I have a BS in Physics save thermal. Kidding above.

  • @sounddoctorin The distance to the virgo cluster is known since the 70s and has not change much, and so that of M87. DO you know anything about the scale of distances in astronomy, BTW?

  • @supergiuovane NOW continuing... I posed a viable point. Now we're going to bring 'jets' into it? We don't know what they mean. Maybe God was just designing beautiful stuff. Maybe they are evidence of something that happened long long ago as a natural process. If so WHAT? We don't remotely know. BH is a guess and I don't see how it has more credibility than 'gas cloud that some massively intense energetic object traversed through'. Show me the math and physics that proves BH.

  • @sounddoctorin I'm not going to show you anything. You should just read why black holes is the most viable and probably only concrete possibility to what it is observed. Evidences go from relativistic doppler shift of Iron lines in the X-rays, to the luminosity variability of quasars, to the motion of stars in their neighbour. There's tons of literature that you can read,including mathematical treatment and physical description

  • Religion has made us who we are. Whether it is good or bad, it has changed all of humanity nonetheless. We shouldn't be talking about how better the world would be if it never existed, because we don't know that we would be living in a world that's any better. But we should be moving away from religion, now that we don't need religion anymore.

  • How did we get in a religion war on a video about black holes?

    :(

  • Artistic impressions based on spectography (speculative measurements based on unsupported beliefs). Black holes are not only a myth, but they are as relevant as the so-called dinosaurs in evolution history. The painting of angels in the Vatican are more realistic because they are based on actual information and communication from the very cause of this universe.

  • Wow awesome video.

  • « I HAVE PROBABLY READ MORE THAN YOU; SICNCE I STUDY BLACK HOLES FOR FEW YEARS »

    [*snigger*]

    Okay, then:

    1. Why are you asking Youtube audience to explain black holes to you and

    2. Why are you still yelling in ALL-CAPS? Couldn't find the CAPS-LOCK key?

  • « WHO ARE YOU TO TELL ME,WHAT IS ENOUGH FOR ME ? »

    Took me half a year to learn enough about relativity theory, physics and astronomy that I could understand the basic facts about gravitational singularities. Nothing stands in your way if you want to learn the same things: I'm just warning you that it'll take a bit of effort.

    And there is REALLY no need for caps. Left side of your keyboard is a key, it's marked 'CAPS LOCK'. Press it.

  • « BUT,NASA SAYS,IT IS A REAL HOLE,MADE IN SPACE TIME »

    There's really no need to use CAPS like that, you know?

    NASA has a better understanding of the principles involved. If you don't want to go so deep into the science of black holes that you get lost, it is enough for you to know that a black hole is a gravitational discontinuity: a point in spacetime so massive that even light cannot escape from its attraction.

  • « WHICH IS IT NOW ? »

    Think of a black hole simply as a gravitational discontinuity: a point in spacetime that is so massive that even light cannot escape from its grasp. That's really all you need to know.

  • Thanks for sharing this. Very interesting. (I love that old movie, the black hole, too).

  • in carl sagans cosmos he talked about how in 10 to the 40th power about everything would be sucked into a black whole. i wonder how scientists think it would be now.

  • « i wonder how »

    Pretty much the same, I think. Couple of hundreds of billions of years from now, all mass will be either free floating elementary particles or locked in black holes. And then those black holes start evaporating. Couple of billions of billions of years from now, even elementary particles will have mostly decayed, and all that's left of everything is a couple of free flying quanta of energy - just enough to heat the universe to a comfortable 0.00000000000000000000000001 K.

  • @mothurman Carl Sagan's statistic is still considered as roughly correct. Well, Carl didn't make the figure but the one he recited.

  • i dont get it.. y ppl dislike such vid????it packs so much info and knowledge n 4 idiots disliked it.. y??? mayb they will dislike abortion vids too or stem cell research vids??farkin religious kunts.

  • Science is a beautiful example of how the human mind can overcome limitations and discover the extraordinary.

  • "Scientific" minds who insult religion are still just ignorant biggots. If you can't respect other people's beliefs, you're still an idiot, no matter how far you've gotten with multivariable calculus. (Most people that can really manage the math that is involved in modern physics realize this is the case.)

  • anyone who can understand these videos does not need to be talked to like a child. ill be leaving now.

  • This is so cool

  • This shit looks sooo good in 1080p

  • When scientists speak about the size of black holes

    is the measuring scale also warped ?

    I always assumed it not to be.

    So objects falling in would shrink

    compared to a not warped measuring scale.

  • Black holes are scary and fun to be with......i know them pretty well

  • Black Holes demonstrate a very basic problem with Big Bang theory..

    Since matter, light, even time, cannot escape the gravity of a collapsed star then following simple logic we are led to conclude that absolutely nothing whatsoever could have ever broken free from the unimaginable gravity of an entire compressed universe..

  • @muzalot Are you claiming there is a limit to the point where something can explode?

    And I think the force of the explosion CREATED the gasses of the universe, I have never heard anyone claim the universe was compressed. As far as I understand, these are completely different concepts.

    But hey, perhaps you are right. You could always send this to an astronomer, perhaps he/she could do something with it. The telescopes are getting stronger fast, perhaps humanity will find out this decade.

  • @GBXS

    Explosions only create gasses when ingredients for said gasses preexist their formation.. Singularity before Big Bang is defined as containing all the ingredients of this universe "compressed" to a point no bigger than the period at the end of this sentence.. Any explosive creation event demands the expansion of space/time however, if TIME cannot escape the holding power of an ordinary Black Hole how could TIME leap from the incomprehensible gravitational pull of a condensed universe?

  • @GBXS

    Consequently our universe could not have come out of an energy/mass of condensed matter that could not have existed without space/time in the first place, that it might create space and time in the second place, so that it can exist in the first place.. To the contrary, begin with a no-thing (THE FIELD) spinning itself into things and instantly we get a revolution in 21st century science, a new paradigm of physics so powerful that it startles us all out of our normal patterns of thinking..

  • @GBXS

    Thanks to Hubble telescope great new discoveries are on the way and everyone knows it..

    Hubble telescope’s observations reveal that the universes expansion is accelerating without the slowing of expansion you might expect 14 billion years after a “Big Bang” explosion.. The universe is expanding by an outward PUSHING, accelerating gravity.. Gravity was never a property of matter, to the contrary gravitational space-time is a flowing field creating and sustaining matter from its spin force.

  • @muzalot

    Do you mean that serious or do you really believe you have found a better scientific theory than Big Bang theory?

    check the following keywords and you might get a better understanding why Big Bang theory does overcome the "basic problem" it to your opinion has with the existence of black holes

    Planck time

    Planck Energy

    Inflation (with regards to the first 10high-36 seconds of the universe)

    unification theory

  • @nelumio

    I'm not as ignorant as you would believe.. I've debated some educated individuals on Planck time theory and not unlike most complicated theories, its viability cannot be verified.. When you begin with a faulty theory such as Big Bang you're inevitable forced to create fantastic scenarios in order to fix contradictions that arise.. At this point, all I can tell you is that Planck time gets decapitated by Occam's Razor..

  • @nelumio

    I absolutely do believe i have found the correct cause and effect solution to how the time, matter, space continuum would have originated.. The key to the "Theory of Everything" begins with understanding gravity as a 2D push force, not the attracting property of matter as we have been led to think of it..

  • @nelumio

    Universal gravity's organic flowing bidimensional field is a sort of two dimensional wire frame preceding our 3D reality.. Primal gravity's "dark energy" field shapes and unifies the other fields and like wind to a windmill, it is gravity's expansion, not contraction that provides the energy for spinning electrons and mass creation..

  • @muzalot TIME CUBE!!!

  • @muzalot

    planck time "decapitated" by Occams Razor, Karl Popper... lol

    It is just logic and normal not to be on the top edge of scientific research anymore today but to make up your own truths and make other people BELIEVE in it is a worrying trend on the uneducated but interested mind

  • MOA!!!!!!!!!!!!!!!! 4:55 moooooooos!!! ULL understand if u aint drunk or high lololol penis

  • MOA!!!!!!!!!!!!!!!!

  • IT SUCK ANYTHING BUT NOT YOU <3

  • black holes are scary yet fun to be with.....i know them pretty well.

  • And while i find this stunning, beautiful and quite insightful to the very nature of our universe I still have friends who will say that its nothing compared to their God.

    Saying of course that I have more faith in science then in God,

    Even though I try to tell them that its not a matter of faith, its a matter of practicality.

    THEN they say its a matter of faith in the very principals of science. =/

    Good lord, there is no talking around these people.

  • @CheshireShade People that say stuff like that simply just do not unsterstand and purposely choose not to.

  • eeveeloution :D

  • I kind of like the music. Can someone provide a link to download it?

  • A black hole the size of the sun WOULD exert much more gravitational pull than the sun does. However, a black hole with the amount of mass that the sun has will excert the same amount of gravitational pull as the sun itself.

  • black holes are soooooooooooooooooo beautiful. i'm thinking wrong O_O

    but i love the universe. THANKS Best0fScience:)

  • Just had a thought pop into my head when the narrator said- "scientist just don't know".

    I always find it interesting that scientists can see things and say " I don't know".

    And religious people can see nothing and say " I do know".

    I hope my quote lives on. -Jimmy

  • r u a food ?

  • Something that has always puzzled me... If gravity is SO strong in black holes why do we see light coming from the middle of a galaxy?

  • @6thMessenger What you are seeing is not the material inside the blackhole, but the accretion disk around the black hole.

  • @6thMessenger The answer is what firevortex500 said and: gravity is strong enough to stop ligh only inside the black hole-s event horizon, which is a sphereshaped boundery around the single point the black hole is. Outside it, you may see optical distortions as the light is curved, but nothing else. What-s more, the galaxy center is so huge that even the black hole is minuscule inside it.

  • @Alpharius93

    Shouldn't the gravity of the blackhole stay the same as the original star it was born from?

    Why would it increase when it turns into a black hole?

  • @6thMessenger I don't know the exact reason but I think it is: when a star, its mass is conserved, but its radius decreases. By the Gravitational Universal Law (power equals constant multiplied by the masses of the main object and a test object's divided by their distance squared), when the radius (included on the distance) is reduced to only some kilometers, the gravity pull becomes huge. And if it becomes a black hole, radius is reduced to 0 so the power goes infinite when on its surface.

  • wooh! science

  • in the beginning it sounded like he said 'welcome to the holocost.'

  • must see live hackbook trick /watch?v=Fd0di5HFboY

  • One question I have is why does a star's core collapse in on it's self when expanding?

  • Great Vid---Keep the good work!

  • how can a stellar black hole have the same gravitational pull as a sun of the same size?? (not mass)?? said at 2:00 minutes. surely if a a black hole the same size as a sun would have a far bigger mass therefore stronger gravity? someone please explain this to me lol

  • @QManKreshy I think they mean mass, actually. Not very properly said, you're right

  • @supergiuovane and density

  • @tullywacker of course, since it goes with "size"

  • @supergiuovane No dbag, of course not, it goes w mass and density size has nothing to do w it

  • @tullywacker Density is the ratio between mass and volume, that is size...

  • Respond to this video...  I think ur being fecicious. I'll give u that haha jokes on me now.

  • nice accent

  • 4:55 has got to be my favorite visualization of the milky way that I have ever seen...

    I want that as a screen saver

  • I don't understand it very well, but I love watching this shit. It's just so cool.

  • I understand black holes. I'm blonde

  • Leave religion out of this. In fact, leave religion out of everything. We don't need it.

  • @LsBaba Well it was needed to forge this society

  • @egadw The world would be a very different place without the influence of religions. A better place.

  • @LsBaba You can't say that unless you've experienced it.

  • @egadw probably best to stay off the religion topic on this video's comments thread. Let's just agree to disagree, and leave it at that :)

  • @LsBaba religions will always exist. in one form or another. even if we put an end to all current world religions, new ones will be born. It is inevitable. Human beings are hardwired to create and follow ideologies, because ideologies organize moral codes, cultural identities, philosophies, spirituality, etc. and we often do so in a "religious" way. It's like saying the world'd be a better place without money, or people....too bad that's impossible to achieve.

  • @F0reseer

    I disagree. It's neither impossible to achieve a civilization without debt, or a civlization without religion. True, humans have religion built into them right now, but one of our greatest assts is our ability to adapt and to change. It is the very nature of biology to evolve, and what is hardwired in us now, may not be later. Hell, it's possible that we're already coming to a point where such things are no longer necessary, and the transition is now at its infancy.
