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.

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?

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?

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.

Thank you so much and I hope you continue to make such wonderful videos.

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'

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.

@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: kzread.info/dash/bejne/hnpstqqSZdbWndI.html ... 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 :)

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.

@@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.

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).

@Sir Woof what makes you think they're not?

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.

Thank You for a great video, big fan of this channel. 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 :)
