@HansBeimler If your information is correct. Then thank you for the update. Altough you should take notest that this series is made in 70:s or 80:s so it naturally does not have every information on cience correct.
so a black hole is really just a star--but its so incredibly dense its gravity bends light/ therefore we can't see it? So theoretically, there is a surface.
The piece of neutron star would create an immense pull on everything around it, shifting gravity as it went. I also think it's unlikely that it would pass through the earth that many times, seeing as it would have to fight gravity, each time it passed through the planet, and not just friction.
@dujl Obviously you don't know what he's saying. I think he means like if something was as heavy as a neutron star but didn't affect Earth with its own gravity, I'm pretty sure he knew what he was talking about, I mean he did get paid for it and all that.
@dujl And you do? Oh wait, you don't Obviously literally that peice of neutron star would affect Earth, but you aren't a professional at all, you're just a person watching a video I never claimed to know anything about this, but I'm not so stupid to know that he didn't mean what would literally happen with a peice of neutron star within Earth's atmosphere.
@dujl Objects don't 'fight' gravity. Gravitation is not a force to begin with. When we're talking about g-forces, we're talking about a constant of acceleration, not gravitation. When you undergo one G of gravity, you 'accelerate' at a rate of roughly 9.8 meters per second per second towards the ground. If an object would fight gravity every time it fell towards the earth, then I would think that satellites in a planet's orbit behave much differently.
pshh if you had a a piece of a neutron star(if you where able to hold it) earth would be pulled to it not the other way around :P and it wouldn't got trough the planet it would collide with it. Fallacies of perspective... gotta love them. (its common sense not rocket science) :P Youtube troll 1, astrophysicist 0!!
@JRMCNEA Same thing mate. People usually just chose to say the greater mass is pulling the lesser mass...though it's relatively just an attraction between the two. This is just Newtonian physics.
@JRMCNEA Same thing mate. People usually just chose to say the greater mass is pulling the lesser mass...though it's relatively just an attraction between the two. This is just Newtonian physics.
@JRMCNEA not true, most neutron stars are extremely dense, but if you had a hand sized piece, it would not weigh nearly as much as the earth, it would weigh as much as "a mountain". and last time i check, mountains dont full the earth towards them. get off your high horse, just cause you think you have a better understanding than someone doesn't make you right.
@ItsNotEvenSunny I am supposed to challenge misinformation. The man was saying it as if the hand full was in fact dense enough that it would in fact be heavier then the planet. And he also implied that this would make it shout through our planet like a bullet through a cake. Which would not happen. And that is what I was pointing out. The two would either collide together or the one would be drawn to our sun. either way it would not "fall" through our planet to the other side. understand?
@JRMCNEA maybe you need to watch the video again, he wasn't saying if the ball he was holding was a neutron star, he was saying if the ball he was holding was made of neutron star material. it would weigh as much as mountains, which would fall towards the earth. understand?
@JRMCNEA I think you need to go back and read my very first statement... I stated that it would NOT "fall through the planet. But collide with it. It would only fall to the surface. It wouldn't "go to China", or break through the planet like a bullet through a melon.... it would land on the planet not shot through it like he implied.
@tacticaloperator12 Argentina is directly opposite to China. If he was in Argentina when he dropped the Neutron Star it would have come out of China like he said.
@Pizzachu1 Haha ok. I'd bet money Carl Sagan wasn't in Argentina or anywhere in SA filming this. My point was if you're going to make an educational video, don't cut corners with common sense statements. Let it go.
if nothing (including light) can escape the gravity of a black hole, why can we detect their presence through x-rays? how can they radiate out of the black hole and reach us?
@xeroxunlimited The gas is swirling around the black hole's event horizon thus it will be able to escape. If you didn't already know, an event horizon is like the point of no return, the beginning of what we consider nothingness in a black hole.
@xeroxunlimited black holes emit radiation in crazy amounts like jets on each side, also all the matter swirling around the event horizon emits radiation.
He mentions dropping a teaspoon of a neutron star on Earth. I wonder...would that teaspoon maintain the same volume when no longer surrounded by the rest of the neutron star?
@iridescentsquids nah it's just so you can make yourself an idea. If a teaspoon gets anywhere close to a neutron star the teaspoon loses pretty much all volume and gets crushed into the star. that thing has an incredibly huge gravity
@ankevson I meant will that small volume of neutron start stay small without the rest of the star's mass surrounding it to keep it compressed? If it's the amount of mass vs outward forces keeping it in it's neutron-star state, wouldn't segregating a teaspoon amount change the mass/outward force balance? I would think it would inflate out of it's neutron-star state of compression and interact somehow with the matter of the earth.
@Shockszzbyyous Lol actually I was trying to figure out if the lump itself would no longer be the same size (let's say 1" in diameter) because it would no longer be surrounded by the rest of the star's mass. In other words, in order to be so dense do you need to have the entire neutron star mass all together? If you take a 1" diameter bit away and move it off by itself, would it still stay just as dense or would the gravitation force be so much less it would expand?
LOL what a fool. blacks aren't important enough to "make up something" to confuse them. who would waste there time in that endeavour? besides, magical concepts like fire and speech cause them enough confusion already. name one black civilization ever? oh thats right they never had one.
perhaps the singularity our universe began as was an output of a black hole in some other universe... if this were true there could me as many universes out there as there are stars... fun theory to think about :D
1. If you're in Washington, D.C, your opposite would be between the southern tips of Africa and Australia. Don't forget to reverse the N/S coordinate as well as the E/W coordinate.
2. An object dropped through the precise center of the earth invokes a divide by zero error when calculating force and acceleration.
3. Carl Sagan is everybody's hero, I know, but it always sounds to me like instead of saying "this is about the way the universe works", he seems to say, "whoah, this shit is trippy."
This video is a bit outdated. But as for the speed of light, as of lately, been prooved as not being a constant and can be slowed and stoped in "mid-flight" right here on earth. And I dont mean stoped by a wall. You guys can thank Caltech for that.
What can happen is that pairs of particles can become separated in proximity to a black hole's horizon, one of which may then fall in, this would annihilates it's opposite charge beyond the horizon thus causing the black hole to 'evaporate.'
xrays are part of the electromagnetic spectrum (light) and cannot escape from a black hole.
Hawking radiation is of every frequency and not only in the x ray range.
Also, does anyone think that maybe the universe is one giant fractal organization of gravity wells? Organized in a way where the large scale structures of the universe are each in gravity wells, followed by smaller structures in wells coming off of the larger wells? This organization would fractal down to the smallest amount of matter until the nuclear forces overcame gravity's influence.
Not really, because when you fell into a black hole you would just come out in a different part of the universe. Still, maybe black holes are so deep that they do connect to other universes (but can we really call them universes if there are more than one?). For the most part though, according to what I've read about quantum theory, parallel universes are supposed to co-exist in the same physical space as ours, just at a different quantum level.
Ok, so gravity is supposed to be the weakest of the 4 forces in the universe... So how does a black hole's gravity overcome the strong nuclear force? Isn't gravity in that instance stronger than the strong nuclear force and thus the strongest force in the universe? I feel like gravity shouldn't even be lumped in with those other forces. It's nature is too different.
Eventually...what exactly happens to a black hole? I think its more likley to be like a scrap car compactor. Stuff is more dense and thats it really! Eventually everything about it weakens and stuff simply gets flung back out into space and we all have to duck! I reckon space stuff simply ebbs and flows like a big breathing thing! The black hole theory along with the big bang scenario does support a political agenda though doesnt it? Space is too hostile and much too big for us at the moment.
and at the blackhole, its supposed to have such high gravity that gravity at your feet is way more than on your head, your body stretches until it tears, and you become a 'spaghetti', or called 'spaghettification'.
Well, Cookie...money and power for a start! After all, what else are most politicians about? And yes you are quite right about 'Spaghettification'. I've seen this a lot in Italy. It leads to super-nova-rotundification and at a higher enough density 'potbellyification' occurs; even Einstien knew about this distortion and enlargement of local mass. I believe it was Carl Sagan that first referred to this phenomenon as the 'mamma-mia effect'!
Its unkown what happens within a black hole, you cannot measure something that does not allow even light to escape. Some theories are that the Mass is so dense that is tears a hole in the fabric of space time.
Were I to fall into a black hole and you sat outside as an observer, you would see me fall toward the event horizon (point of no return) but I would never pass it, time would be so slowed by the dilation of time. As for political agenda not too sure.
Quantum theory suggests that even though we once said it couldnt happen, that matter does indeed escape a black hole over time (can be seen at poles of the hole where jets of matter can get free) and that they dissipate. What would happen when if finally goes? Who knows? Boom?
black holes 'evaporate' due to a process called Hawking radiation. the jets you describe are features of the electro magnetic field and accretion disk surrounding the singularity, although not fully understood, they are not material being ejected from beyond the gravitational field behind the event horizon.
Please do some reading on Hawking radiation.
Because here you seem to be talking absolute nonsense.
Well link me a reference so I can do some reading, i I do only have a laypersons understanding.
As for the matter being ejected at the poles I wasnt ascribing evaporation to this process, just that some matter can indeed escape from a black hole although as you said not from beyond the event horizon. Nothing gets away from that point.
As for the condescendng attitude, save it please. If you have an expertise share it, not the hot air.
Sorry if I seemed rude, I am just trying to push the point that nothing can escape from a black hole.
Have a look for an article on Space dot c om called
'Black hole jets explained'
"mass distorts space and time around it [BH], twisting magnetic field lines into a coil that propels material outward."
"researchers have observed a jet during a period of extreme outburst and found evidence that streams of particles wind a corkscrew path away from the black hole, as the leading hypothesis predicts"
they evaporate if the rate at wich they expell matter is bigger than the rate they suck in matter
supermassive black holes would evaporate when they run out of matter to suck ..an that would take ages
a micro black hole ..something the LHC could make ..should evaporate in 10* -43 seconds :D thats too fast to be detected ...so we probably wouldnt know if we ever made a micro black hole ..
What you fail to realise with your 3 dollar education is that this was made in the 70's give the old bastard a little credit. Carl Sagan you are the shit.
Also, i think its important to supplement the analogy of space/time as a sheet of grid paper. space is the 3rd dimension so it would be a 3d form of this sheet. just replicate the 2d grid on every possible 2 dimensional plane and you a more accurate representation of the distorion of space/time that is gravity
But how is it we would exit this worm hole? If it is caused by a black hole, which is charaterized by gravity so strong it bends light, would we not just renter the hole and stay at a point inbetween the two entrances?
Black holes don't sit there just gobbling up matter. Unless you are shoved directly at a black hole, it's far more likely that you will be slingshot around it. If you don't directly hit it, then you are slung away taking time to burn off all that momentum you built up approaching it. But, it you hit the "event horizon", that is where space is curved so much that straight path spirals you down into it.
tesla proved that einstien was wrong! tesla sent industrial energy almost infinitly faster than light this disproving the einstien gravity stuff. teslas technology would lead us to instant communication anywhere in the universe, i already proved teslas wireless communication , the device that creates faster than light effects on my youtube account!
ok some of teslas wave propagations are 10 times faster than light! the cosecant wave propagation has a infinitly curving function, this is how the waves functions from the tesla device! i know ur brainwashed by einstien but tesla proved einstien was wrong with real experiments in reality!
Nothing can reach the speed of light, and if anything reaches speeds faster than the speed of light then the speed doesnt change, but the time becomes distorted instead.
You REALLY should read up on the theory of relativity.
About Nikolai proving Albert wrong.. no, you have no understanding how the scientific community works, Tesla only spread rumours to higher offices to promote himself.
Otherwise his projects would get adopted by other scientists in tests.
thats bullshit! you can keep subdiving the second without going backwards or "time warping", thats the fucking retarded shit! you can go faster than light tesla did it, the sun does it, it charges some cosmic rays to billions of volts of acceleration and flings them off in the vaccuum of space, which causes them to go many times faster than light! you have no clue! lol! no one ever tried it except tesla and now me! its real! ur just brainwashed!
I am sorry to say this but you sound like a super retard. You seem to have read a few books but unfortunately you do not show an understanding of the fundamentals of Science... Which is "never make stupid statements".
How do you know "Nothing can reach the speed of light"? (or maybe exceed it).
In cosmic timescale, a brainfucked fucktard like you making claims like these is really retarded. Read up some more and get you brain to become a little more open.
@ahmedhusseinny If you had made might it be the simplest calculations involving relativity, you would know that for anything that has mass, it takes an infinite amount of energy to reach the speed of light, it is impossible simply because the more you are close to it, the more energy you have to put to get closer again.
@2CSST2 Sorry but you seem to have missed the point I was trying to make with my comment. All I was saying is:
1. Based on our knowledge today, the highest speed we know is "c".
2. That may very well change in the future.
3. Science allows us to keep an open mind, and keep looking for answers. Theory of relativity explains quite a few things, not a whole lot though. The quest must continue.
@ahmedhusseinny General relativity is not fully understood in its whole, but the fact that the constant speed of light in unattainable is very well understood and uncontestable. You're totally right science allows to be skeptics on its theories but at some point you have to stay reasonable on that. I've had classes on general realitvity, and I can tell you it's definitive no object with a mass can attain the speed of light just like a temperature cannot be under the absolute zero.
I sound illogical, but this is what thousands of science experiments tell us.
Light speed is constant no matter in which direction you look and how fast you go. And light-speed in vacuum is the maximum speed possible. Matter can never reach light speed but can come close to it.
They did it too in the 60's, placing 2 synchronized atomic clocks, 1 at groundlevel and the other at the top of a watertower - even at these small height-differences the atomic clocks were precise enough to detect a time-difference. Not JUST a difference though, but the EXACT difference einstein's theory predicted.
@naturalyshocked well actually the speed of light does actually change, the numeral value is the speed of light within a vaccum, yet when light passes through substance say water, then it changes speed, and that is when you get refraction
@ahmedhusseinny In fact the whole relativity theory relates on that, all of its predictions are consequences of preludes of which this one is part of. So without this granted, none of what the theory says is true, including the dilatation of time, which is observed daily in particle accelerators
@ahmedhusseinny Temperature was a very good analogy as it has also been demonstrated that it is impossible for an object to reach a point of absolutely no energy, there is at least always 1 quanta level of energy present. Thus the point of absolute 0 is impossible to reach or excede, the fact it is a reverse extrapolation to 0 doesn't take away any credibility to the comparison, either by increasing amount of energy or decreasing, the same principle is there: a physic constant unreachable.
@KarinMikazuki uh wrong what you say, the more you approach light speed, the more mass you get, E=mc^2 see c is constant so only E and M can change and you need to have energy to move... so m changes your mass changes till it gets as big as the universe, that's why. you'll need infinite energy to do that.
that's why you can't travel at the speed of light,
well how about foton's?
they are massless so take mass out of the equation and it's possible.
"Disproving the einstein gravity stuff" I've seen your video and read your comments. You are a stunning, breathing example of why humans may not ever venture to the stars. You are a retard. Yes, a drooling, blathering retard.
well, location is a reasonable theory, but time, not so much. To go to a different time, that would suggest that by passing through a black hole it would either reset every molecule in the universe to a previous state, which is absurd, or suspend every molecule in the universe while not effecting what is passing though the hole.
This comment has received too many negative votesshow
Carl Sagan is too 80's for me and he seriously sounds like Swedish Chef. Its not that i dont find this video interesting, im just too annoyed to watch it...
Judging from the style and music of the video - I''m going to assume that it was at least made in the 1980s. So it's possible that that's (despite having discovered them by that time, as he said) as much as they knew or thought they knew about black holes at the time.
The show Cosmos was aired in the mid-late 70's to the early 80's.
To RagingSeraphim, careful, your age is showing. You might want to go look up Carl Sagan and find out just who you're commenting on. Also, remember, this episode predated the acceptance of Stephen Hawkins' theories on black holes etc. Further, not everything falls past the event horizon. Much matter is ripped apart and shot out of the jet streams black holes have thus far shown to possess.
@PainBehindMyEye well said...Black holes do not swallow everything...They are not space eating monsters..When Light from elsewhere hits the event horizon it goes into orbit around the EH
idk how much pot this guy was smoking but black holes are not wormholes. they are quantum cingularities. a single point in space of infinite density. the only way to escape the gravity well is to go faster than the speed of light. once ur crushed in the center...that's it.

how do xrays escape a black hole?
TheRealTaco87 2 years ago
Nothing escapes a black hole TheRealTaco87.
What can happen is that pairs of particles can become separated in proximity to a black hole's horizon, one of which may then fall in, this would annihilates it's opposite charge beyond the horizon thus causing the black hole to 'evaporate.'
xrays are part of the electromagnetic spectrum (light) and cannot escape from a black hole.
Hawking radiation is of every frequency and not only in the x ray range.

Maybe black holes create such large gravity wells that they merge with similar wells on other fractal arms of the universe, creating wormholes.
Does this make sense to anyone? I don't know... it's just a crazy idea I just had.
fightforyourrights9 2 years ago
Also, does anyone think that maybe the universe is one giant fractal organization of gravity wells? Organized in a way where the large scale structures of the universe are each in gravity wells, followed by smaller structures in wells coming off of the larger wells? This organization would fractal down to the smallest amount of matter until the nuclear forces overcame gravity's influence.

I think this idea is similar to the Parallel Universes' one, isn't it?
FlaviaSantosbr 2 years ago
Not really, because when you fell into a black hole you would just come out in a different part of the universe. Still, maybe black holes are so deep that they do connect to other universes (but can we really call them universes if there are more than one?). For the most part though, according to what I've read about quantum theory, parallel universes are supposed to co-exist in the same physical space as ours, just at a different quantum level.
fightforyourrights9 2 years ago
Ok, so gravity is supposed to be the weakest of the 4 forces in the universe... So how does a black hole's gravity overcome the strong nuclear force? Isn't gravity in that instance stronger than the strong nuclear force and thus the strongest force in the universe? I feel like gravity shouldn't even be lumped in with those other forces. It's nature is too different.

Eventually...what exactly happens to a black hole? I think its more likley to be like a scrap car compactor. Stuff is more dense and thats it really! Eventually everything about it weakens and stuff simply gets flung back out into space and we all have to duck! I reckon space stuff simply ebbs and flows like a big breathing thing! The black hole theory along with the big bang scenario does support a political agenda though doesnt it? Space is too hostile and much too big for us at the moment.

and at the blackhole, its supposed to have such high gravity that gravity at your feet is way more than on your head, your body stretches until it tears, and you become a 'spaghetti', or called 'spaghettification'.
cookiejun 2 years ago
Well, Cookie...money and power for a start! After all, what else are most politicians about? And yes you are quite right about 'Spaghettification'. I've seen this a lot in Italy. It leads to super-nova-rotundification and at a higher enough density 'potbellyification' occurs; even Einstien knew about this distortion and enlargement of local mass. I believe it was Carl Sagan that first referred to this phenomenon as the 'mamma-mia effect'!
stopjunkscience 2 years ago
Its unkown what happens within a black hole, you cannot measure something that does not allow even light to escape. Some theories are that the Mass is so dense that is tears a hole in the fabric of space time.
Were I to fall into a black hole and you sat outside as an observer, you would see me fall toward the event horizon (point of no return) but I would never pass it, time would be so slowed by the dilation of time. As for political agenda not too sure.
Urbanninja3 2 years ago
@Maltesevideos
Quantum theory suggests that even though we once said it couldnt happen, that matter does indeed escape a black hole over time (can be seen at poles of the hole where jets of matter can get free) and that they dissipate. What would happen when if finally goes? Who knows? Boom?
shkotay 2 years ago
shkotay, that is not correct.
black holes 'evaporate' due to a process called Hawking radiation. the jets you describe are features of the electro magnetic field and accretion disk surrounding the singularity, although not fully understood, they are not material being ejected from beyond the gravitational field behind the event horizon.
Please do some reading on Hawking radiation.
Because here you seem to be talking absolute nonsense.
marsCubed 2 years ago 5
Well link me a reference so I can do some reading, i I do only have a laypersons understanding.
As for the matter being ejected at the poles I wasnt ascribing evaporation to this process, just that some matter can indeed escape from a black hole although as you said not from beyond the event horizon. Nothing gets away from that point.
As for the condescendng attitude, save it please. If you have an expertise share it, not the hot air.
shkotay 2 years ago
Sorry if I seemed rude, I am just trying to push the point that nothing can escape from a black hole.
Have a look for an article on Space dot c om called
'Black hole jets explained'
"mass distorts space and time around it [BH], twisting magnetic field lines into a coil that propels material outward."
"researchers have observed a jet during a period of extreme outburst and found evidence that streams of particles wind a corkscrew path away from the black hole, as the leading hypothesis predicts"
marsCubed 2 years ago
The jets are composed of particles travelling at less than the speed of light.
gravity is throwing particles out before they come close enough to fall in.
Think of it as a close orbit which sling-shots things out maybe.
The 'shock wave' around the horizon has something to do with this I believe,
I am no expert on black holes, however nothing can escape the BH itself, due to space time being curved in on themselves.
Jets are not fully understood yet, from the reading I have done.

they evaporate if the rate at wich they expell matter is bigger than the rate they suck in matter
supermassive black holes would evaporate when they run out of matter to suck ..an that would take ages

stinny777 2 years ago
Black holes don't sit there just gobbling up matter. Unless you are shoved directly at a black hole, it's far more likely that you will be slingshot around it. If you don't directly hit it, then you are slung away taking time to burn off all that momentum you built up approaching it. But, it you hit the "event horizon", that is where space is curved so much that straight path spirals you down into it.

@ahmedhusseinny If you had made might it be the simplest calculations involving relativity, you would know that for anything that has mass, it takes an infinite amount of energy to reach the speed of light, it is impossible simply because the more you are close to it, the more energy you have to put to get closer again.

@2CSST2 Sorry but you seem to have missed the point I was trying to make with my comment. All I was saying is:
1. Based on our knowledge today, the highest speed we know is "c".
2. That may very well change in the future.
3. Science allows us to keep an open mind, and keep looking for answers. Theory of relativity explains quite a few things, not a whole lot though. The quest must continue.
ahmedhusseinny 1 year ago
@ahmedhusseinny General relativity is not fully understood in its whole, but the fact that the constant speed of light in unattainable is very well understood and uncontestable. You're totally right science allows to be skeptics on its theories but at some point you have to stay reasonable on that. I've had classes on general realitvity, and I can tell you it's definitive no object with a mass can attain the speed of light just like a temperature cannot be under the absolute zero.
2CSST2 1 year ago
i don't think the speed of light is constant, just like the speed of sound isn't constant.
if gravity can bend light, it should have effect on it's speed.
also the speed lowers as it travels true differenrt mediums.
dark matter is asumed, but not yet 100% proven.
yet something tells us there must be a unknown factor/force we can't see and it should account for aprox 94-96% of all matter.
there are things we still can't interprete.

@ahmedhusseinny In fact the whole relativity theory relates on that, all of its predictions are consequences of preludes of which this one is part of. So without this granted, none of what the theory says is true, including the dilatation of time, which is observed daily in particle accelerators

You would imagine that with a Ph.D in Physics, I should know all this.
But you are still missing my point. Let me break it down for you.
1. Our knowledge of Physics (specially Theoretical Physics) is no nascent,
that, there are conjectures we cannot even begin to wrap our heads around.
Our "toolbox" does not have enough tools. That said, can you convince me
that in the year 4010 we cannot transmit information/energy faster than light?

@2CSST2 3. Coming back to my very first comment to KarinMikazuki where he said
""Nothing can reach the speed of light"?" I objected to that deterministic statement, meaning, based on what we know (only because it has not been
disproven or even completely understood), it appears that exceeding the speed
of light is very highly unlikely.

That is what is called scientist speak. Thats pretty much all there is to it.

PS: Temperature was not a good example/analogy. :-) It is obtained by reverse extrapolation down to 0.
ahmedhusseinny 1 year ago
@ahmedhusseinny Temperature was a very good analogy as it has also been demonstrated that it is impossible for an object to reach a point of absolutely no energy, there is at least always 1 quanta level of energy present. Thus the point of absolute 0 is impossible to reach or excede, the fact it is a reverse extrapolation to 0 doesn't take away any credibility to the comparison, either by increasing amount of energy or decreasing, the same principle is there: a physic constant unreachable.

that's why you can't travel at the speed of light,
