I'm doing my PhD on black holes & I just finished doing an analysis of the black hole spin in GRS 1915+105 (it was actually the first BH in the table of spins you showed). I was super impressed by how accurate everything in your video was! I study all of this for a living right now lol. I also loved the animations - I always have trouble finding a good accretion disk animation which shows how the ISCO shrinks as the black hole spin increases. A fantastic & informative video.
Badass
Just a thought - anything that travels faster than light will disappear from all of the scientific instruments - or it will be detected as dark/black - since it is beyond the light spectrum... Think about the particles that appear & disappear in quantum fields... These stars & Sun are not mere objects in the sky, they are alive and in fact more alive than a human can comprehend... Many scientists in the past were rarely distracted by their instruments or theories and therefore they were able to bring out revolutionary concepts from the depths of their minds... The more you measure, the more you miss out on the detail... The way forward for the science is to go beyond the limitations of the light... This is possible from within and not without...
Is it approximately correct to think of the energy released (as grav waves) when 2 black holes collide, as the difference in potential + kinetic energies before & after the collision?
Do concepts like PE & KE apply in GR?
Is any of that energy released as EM radiation?

@SmarterEveryDay Derek's talk about spin made me think about the toilet swirl - please make a video on black holes!

I have a question for both of you...
I have heard it said that, due to Relativity, if a person were to fall into a black hole, it would appear to an outside observer that the falling person would slow down and freeze in place at the point they reached the event horizon. If that is true, it would also suggest that time would appear to speed up for the falling person, looking back at the observers. This has made me wonder what the limitations of that time warp would be. Would relative observer time continue to get faster and faster as the person falling continued to get closer to the singularity? Would it be theoretically possible to witness the end of the universe as one fell into the black hole?
Sorry, Destin. I saw this before you... 😉

From the perspective of general relativity, they are quite simple actually 😁 one of the simplest solutions to einsteins field equations.
Conversely, real black holes with all their quantum weirdness that we don't really know much about, are probably the most complex things out there 😂

Wait, Bill Gates moved into a Black Hole now?
Since regular pulses are common in the Universe and occur naturally, aliens, who are trying to contact another intelligent life, would have sent some flashes in a distinct pattern - like for example 1 flash at every prime number seconds.
Perhaps I'm misunderstanding but isn't ISCO the wrong thing to focus on here regarding on the limit of the rotation, the ISCO is for matter orbiting the black hole. Photons departing radially outwards can escape for any point exterior to the event horizon regardless of the rotation. For a black hole with a rotational parameter of more than 0.28 photons can orbit prograde in the plane of rotation right down to the event horizon.
Isn't the problem with rotation parameter > 1 the fact that the kerr metric would create a ring shaped singularity that had a radius larger than the Event horizon, and therefor expose a 'naked singularity'
Scott cawthon
That's what I'm thinking 🤔
Maybe
Hey Scott, fancy seeing you here.
I was wondering the same exact thing. the ISCO is for solid matter, we should be looking at the photon sohere, or the IBCO.

Our universe is a black hole
@@zodiacfml White hole not a black hole as we are moving away from the singularity not towards it.
If you pass through the event horizon of a black hole, the reason you cant escape is that the space-time curvature is so extreme that all paths leads to the singularity, which ever way you looked you would see the singularity, it would look like it was smeared into a shell around you.
The big bang is a singularity, as we look farther away we look further back in time, look far enough and we can see back to the big bang (we are stopped from being able to see it due to the surface of last scattering), you would see the big bang in any direction you looked, it would be smeared into a shell around you. The only difference is that we are moving away from the singularity, like a black hole going backwards in time, which is called a white hole.
The real question is
Does the universe spin
No, it is stuck facing one direction, the outside.
@@davidroyer8516
Angular momentum can only be assessed relative to something else around it that you consider stationary. Ultimately you run into the need to either 1) have an outside as a reference, which doesn’t exist for the universe, or 2) to define the universe itself as stationary, in which case the total angular momentum must add to zero (unless you can find a way to violate the conservation of angular momentum law).
Either way, the universe does not spin.
@Liam Boyle
Yes there is galactic spin, but the central black hole is not exactly at the center of the Milky Way (just close). The galaxy as a whole has some kind of slow spin about its true center. The gas, stars and the central black hole all orbit around this true center at a faster speed than the galaxy as a whole spins, but with different speeds for each object, slower as you move away from the center. This means objects pass into and out of the galaxy’s spiral arms over time. Other galaxies all spin at different rates and in different orientations to our galaxy. Same for planetary systems within our galaxy. Some stars even orbit within smaller circles inside their big circle around our galaxy. It’s evidence of an unpredictable universe designer.
It's all relative.
@Liam Boyle You're absolutely right! :) The European Southern Observatory in Chile watched stars orbiting the the black hole at the center of the Milky Way this past year, viewable here: krplus.net/bidio/hKpwhniLZ6rUnqA ... The folks here though are wondering about whether the universe in general is rotating, which maybe remains an open question. I suppose it depends on whether the Milky Way and other galaxies rotate about some universal center. As I understand the Big Bang Theory, there is no implied center to the universe. Expansion doesn't so much radiate out from a single point, rather it is as if we are on the surface of an expanding balloon. I would also suppose that we have much to learn still about the nature of the expansion of the universe, the distribution of dark matter, why the higgs is lighter than expected, the specifics of quantum gravity, and a host of other questions before we can make any declarations. It's fun to think about though :)

@@penguinexpress12 their effects aren't
@@christopherjones7191 They aren't. Not if you are travelling through space, anyway. Black holes are extremely uncommon compared to other stellar objects. This means it's already very unlikely to find one, especially since space is so incredibly empty in the first place. After you find a black hole, you need to get extremely close to it to experience its tidal forces. Even if you approached a sun-mass black hole at 1au, you would experience nothing more than the gravitational pull our Earth experiences. For stellar-mass black holes, you would need to get very close - probably within the radius of the sun - to start experiencing tidal effects that can be seriously harmful.
@@huaen8880 I agree with you.
My intention for that sentence was that while the black hole itself was infitesimally small, its gravitational effects were still much greater than their small size would suggest.

Quick questions from a know-nothing: I'm confused about the dwarf star orbiting the black hole, the one that you described as always there but not visible until the star was sucked in to the black hole. I assume that its orbit is in a place of equilibrium where the gravitational force pulling the dwarf star in matches the centripetal force of the spin pushing it out. But then a star gets sucked into the black hole. Wouldn't that massively change the gravity of the black hole? According to your explanation, such an event would also increase the spin, but are we saying that increase in mass and increase in spin are equivalent somehow? Or did the dwarf star change its orbital pattern after this event? I guess we can't compare before & after, but is it in any way possible that it DIDN'T change its orbital pattern after such a dramatic event? How would a star getting sucked into a black hole change the trajectory of an object already in orbit around that black hole? Wouldn't it disturb the orbital pattern greatly in the short run, then, settling down, cast the dwarf star into a new long-term orbital pattern? The bigger implication of what I'm asking is whether the dwarf star was actually there and orbiting in that manner before the event, or if the event introduced the dwarf star into orbit or somehow dramatically changed its orbit. Thanks for the time, and thanks especially for the great videos.
I see black holes I get this eerie feeling... They are just so mysterious. Thanks for clearing some of the mystery, Derek.
At some point, I lost focus of the terminology and was sucked into his voice. Then I hit the isco and pulled myself back together. I feel brighter now.
So can we assume the black hole "gargantua" in interstellar fed on a star at some point too?
Cool. Great video by the way ^^
Yes!
Yup, and Gargantua was also a spinning black hole! Movie logic dictated that it spun at near the theoretical maximum (as that's the only way time would have worked like it did on Miller's planet... that, and Miller's planet being much closer than was depicted), but the final on-screen render showed the black hole rotating at 60% of the maximum instead, as 99% would have caused Gargantua to look a bit lopsided and distorted, which may have confused viewers (as opposed to looking only slightly lopsided).
Gargantua fed on love. It is believed the spin of Gargantua was exponentially fuelled by Christopher Nolan's ego.
@@NukeMyHouse I see someone have read "The Science of Interstellar".
It was a great read for sure.
I imagine risco like the whirl in a toilett or bathtube in 3D, as faster it spins (as faster the water floates down the pip/fermions and bosons go down the hole) as steeper and more sharpened the whirl walls are. 😅 You did a very good job in explanation!

@@thehoovah It's part of its charm. Of course, we can't really say ANYTHING 100% for sure (this could all be just the matrix and we wouldn't know) but we still try to understand the universe around us with the current information we have. If, however, this is proven to be incorrect, then that just meant that there's a better explanation that we have yet to find and the journey to learning about this phenomenon begins anew. This time, we are equipped with a better understanding than last time (since we DID disprove the previous theory and what made that possible didn't come from nowhere).
Thank you for the explanations. Great work thank you
Excellent presentation as always, thanks for the education.
Just FYI, redshift can only be used to calculate distance at very large extra-galactic distances where the expansion of the universe accounts for most of the object's observed motion. At distances where we can resolve individual stars from stellar clusters (as opposed to resolving individual stellar discs), which we can only do within our galaxy and some members of the local galactic group, cosmological redshift can't be used because the Doppler shift primarily traces the stars' peculiar motions within their galaxies or of their host galaxies through their group or cluster. We can use stellar spectra to gauge a star's distance, but to do so we have to compare the spectra to stellar evolutionary models to distinguish dwarfs and giants of the same temperatures and estimate the star's intrinsic luminosity at that stage in its life. For isolated stars (not part of a multiple system or cluster but free-moving in the galactic potential), stellar evolutionary models are often the best distance-estimating tools available, and that's not saying a whole lot.
I kind of understood the first half of your comment, then I got lost :(.... men I wish I could have studied astrophysics *sigh*
"Free-moving in the galactic potential..." what a beautiful idea. What a lovely turn of phrase. Did you make that up?
@@tampauser6879 it's a succinct definition of the term we'd use, "field star", although I evidently sacrificed too much clarity for brevity. "Galactic potential" was short for the potential well of the Milky Way. We use the term "potential well" a lot in the field to describe the gravitational sphere of influence of a mass or (more often) group of n masses where n may be a large number. "Potential" comes from "gravitational potential energy", and the "well" part comes from the way we often try to describe intuitively how massive objects deform space according to relativity. The usual metaphor is a bowling ball on a tautly stetched sheet: the ball creates a depression or "well" that makes smaller objects dropped on the same sheet fall toward it.
Are there galaxies from the local group from which we can identify individual stars? I thought that's only possible for within the Milky Way...
@@PaskalS some particularly massive stars can be picked out in the Magellanic Clouds and the sparse outskirts of the Andromeda and Triangulum galaxies. It's hard af, though.

I do have a question though and I apologize for potential ridiculousness of it as astro-physics or or really any physics is very far from being my daily subjects of involvement but are much of personal curiosity. So if the massive star that got eaten by the black hole actually got consumed while passing by the black hole then wouldn't it's trajectory have to intersect with the actual event horizon of the black hole in order to be effected or is the animation just not correct? Also wouldn't the mass of the star that got eaten have to be smaller than that or the dwarf star that is apparently circling the black hole emitting those x-rays in order to experience effect of the gravity since the dwarf star manages to circle around without the experience of the same effect? and lastly how come there is any light or debris left circling the black hole? by my logic if the large massive start got engulfed while passing by then there really shouldn't be anything left from it and only hawking radiation would get emitted according to some earlier videos from this channel. Greatly appreciate any potential relative responses :)
Wow. This was a really good video. I like it! Keep being awesome!
Very nicely presented. Thank you for this video.
This man deserves a Nobel Prize. His videos are the ones which have motivated me to understand science , not memorize it.
I understood... some of it
Hel yeah me too. 😂
Whatever he told about was simple Physics that you usually study in school, he wasn't talking of higher level concepts, so if you are a kid you will soon read the formulas and terms he used.
:) it's not that hard.
@@cloveramv Not really. Many concepts were higher level. I was never taught about black holes or anything about black body radiation or the acretion disk in school. I learned it all myself.
More than I did...and yet I optimistically watch.
This is what Vsauce should've always been like: free for everyone.
Because if someone is good at something, they should always do it for free...?
@@Roxfox yeah not paying a conceited douchebag a monthly fee to watch youtube videos
@@matguimond92 I don't know why you think I care, but that's fine. It's your decision, and a sensible one as far as I'm concerned, if you were looking for validation.
@@matguimond92 what is with the entitlement ? Its his content, he can charge for it if he wants to.
Roxfox you make it sound as if he wasn’t getting paid at all. Monetization on KRplus works like network television. VSause had a lot of subscribers and views so the advertising revenue should have been pretty substantial. This doesn’t even mention the ability to sell merchandise, obtain episode sponsors and Patreon. You’re ultimately right though, it’s Michael’s choice, but he wasn’t doing it for “free”...not anymore than NBC, CBS, Fox etc.
School should teach this way.
Awesome video as always.
I sure am glad they don’t express it as diameters, or it would be a disco!
Copy cat
next video: can dark matter be made with strong enough coffee?
Brown matter could be made with strong enough coffee, *but that’s for a different video* 👀
Black matter *is* strong enough coffee
Only if nibbler eats it.

@Sir Woof trump
They would be extinct by now as this happened millions of years ago.
@Sir Woof This is the stupidest thing I've ever heard
@@zapcrossworld4036 dafuk 🤣
@Sir Woof what makes you think they're not?
5:17 "This is called a naked singularity, and it makes a lot of scientists uncomfortable" 🤣 🤣 🤣 an underrated pun. Kudos and congrats 👍🏾
Very nicely presented. Lucid and understandable.
Umm this happened 250milion years ago
Step up ur game guys.
Patience.
That's actually got me trippin lol
Or does it only occur when we view it? It's all relative
@@penguin44ca that's not how light works
@@eattoast6378 BUT THATS HOW MAFIA WORKS
Just curious....If the galaxy is 290 million light years away and we are detecting this event now, does that mean the event actually happened 290 million years ago ? since the information would have taken that much time to reach us.
Yep ! :)
Yees
Mhm that’s how the mafia works
Yes.
this is why star wars can never work
Thanks a lot for this video. That spinning phenomenon looks to be due to the coriolis force.
I would like to know about the black holes magnetic fields too.
I swear this is the most interesting black holes video on YT
9:47 what's the fissure artifact that just popped up at top right of screen?
Looks like an eye lash lol

space worms lol. Looks like a green screen error.
"This is called a naked singularity, and it makes a lot of scientists uncomfortable"
Not the only naked thing that makes them uncomfortable
Yeah, your mom has that effect on people.
Wow.. nice explanation !!!
Hey Derek, what exactly is spinning i.e. what is there to spin if it is really a singularity?
Also, if you have 2 black holes of indentical size, in close proximity, with acretion disks on precisely the same plan, but one is inverted wrt the other (so that they are spinning opposite to each other), if matter in both acretion disks is moving at >.5c, what happens when matter from one disk collides with matter from the other as the blackholes spiral in to each other?
My guess is that some matter will be exchanged between the two black holes and some will escape their stable spinning orbit.
@@Victor_Marius The question was about matter impacting matter where their closing speed is > c
It seems that spinning black holes are thought to form tight rings rather than points - a "ringularity."
10 April 2019 first ever image of black hole seen by public.
@Claudia Juarez dude it was a multinational project that started at least in 2017, it had multiple petabytes of data to construct, it took the largest radio array ever made to image it. Shut up if you don't know what you're talking about.
@Claudia Juarez i conclude you are a very smart flat earther, tell me if i'm wrong
Ok, I think you'll stop saying your opinion on the internet, and think about that people can always disagree with ya, but tho bruh I think it's real smh
@Claudia Juarez The distance and obstruction: WHY DO YOU THINK THEY HAD TO USE AN ENORMOUS ARRAY OF TELESCOPES ACROSS THE GLOBE? FOR FUN?
Conclusion: you are one of those conspiracy theorists on the history channel at 3:46AM
I love your content :)) keep making videos
thank you!
9:00 A neutron star core or neutron star core remnant could also apply.
If the perceived emission has both rise and fall, instead of being near
instantaneous (which is arguable upon framerate of perception)
It's probably an orbiting emission.
I'd also check for other spectral outputs, to see if these would too
exhibit the same rise and fall in similar period.
In fact, when considering any other type of star, the part facing
the black hole would have attracted more, which would allow
falling into the black hole, as teh surface gravity of such a remnant
can't keep up with the lower orbit speed that's neccesary to keep it
in orbit.
The outside would have to have a greater gravity or cohesion in combination
with the centrifugal force to stay intact, or be pulled apart.
When the orbit speed + cohesion through surface gravity is exceeded
the orbiting mass spaghetties into the black hole.
just a few months later, and you'd have been able to show an *actual picture of a black hole*. incredible.

Will you ever do another collab video with someone where both videos are meant to be played together simultaneously? Like the toilet flushing video.
