Spinning Black Holes 

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?

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 😂

go through the square people pipe Destin! I learned a lot about black holes in making this video...

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

how about Uranus

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... 😉

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TF8THY5spmo.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 :)

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.

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.

Niles Samaniego Black holes are really tiny 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.

Christopher Jones but it would only be the same gravitational pull as a star of the same mass

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.

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).

Interesting question. However: Is it even a valid question? Would there be any conceivable way one could detect the difference without observing from outside the universe somehow? I'm not talking about feasible with our current technology, I'm talking about theoretically possible. If not, then the question is unanswerable and meaningless.

@@silkwesir1444 I don't know enough to know that lol - but its never bad to ask imo :)

If there is an big bang origin in space, which there is not to our current knowledge. Only an origin in time.

Simple answer: no. Long answer: A common misconception is that the big bang was a single point that originated the entire universe. This is not exactly what happened. In reality, it was a violently fast expansion of the universe. Imagine you have a deflated balloon and that you draw a grid on it. Then, out of nowhere, you inflate it really really fast. Ignoring that it could pop, you notice that the grid is still there; the squares are just much larger. There are no new squares. That's what the big bang was like. We live in a single square (the observable universe) that once was very small. If you also draw dots inside the squares, you may notice that they don't grow in size - just space itself does. Things didn't start expanding out of a single point, everything started to get further away from everything else. The name "big bang" causes a lot of confusion and people think that it was an explosion. A more appropriate name would be something like "big stretch". Why do things spin in the universe? Imagine you have a sphere. Now, roll it on the floor. Ignoring things like friction and slope, the sphere will just keep rolling in a straight line, forever. Now, imagine that you attach it to a rope, and that you hold the end of the rope really close to the floor. Now, if you try to roll the ball, it won't go in a straight line, it will start spinning around the end of the rope, like a bow compass. The rope is like some kind of force that is pulling the sphere and not letting it go. Gravity is a bit like this rope. Things in space would just move randomly in a straight line, if it weren't for gravity - a force that attracts things, making them spin around each other. This force gets stronger the more massive things are. Taking all of this into consideration, it becomes clear why the whole universe isn't spinning around the origin of the big bang: first, because it doesn't exist. EVERYWHERE is the origin of the big bang. And if there was a single point where everything originated from, there would be no reason for anything to spin around it.

Assuming for a moment our universe is infinite, which it seems like it is (due to its impressive flatness), the big bang didn't occur at a particular point in space. This is part of science communication that really bugs me: the conflation of our universe with our observable universe. When we say that the universe was squished into an infinitesimally small point, what we're referring to there is the observable universe. Prior to the big bang, if the universe is infinite, the universe was still infinite. It's just that the very big, finite volume of it we can observe today and into the future that was squished into a point. The big bang, rather than happening at a particular point, occurred everywhere, or at least everywhere that our observable universe used to be. There's no single point today or then around which the universe might rotate. I do recall, however, reading about a GR solution that gave you time travel in a rotating universe, so I really hope I'm wrong, I've got some personal fashion trends I want to correct.
