innertubez that’s a really interesting question. A black hole isn’t “anything” except spacetime because all of its matter is crushed to infinite density. So when we say it’s spinning we’re really talking about the spacetime of the black hole. Weird, huh?
Thanks for yet another top quality informative video from our friendly neighborhood astronomer! Your pacing is perfect for me, it doesnt make me sleepy, and it isn't too fast. Another great job! 👍
Your channel is just as good, if not better, than the big serious science channels. And you yourself are such a friendly person! Thanks for making such great content, Christian!
Man, you have a great voice. We are all in search of this type of content. You make it so much more pleasant to consume. Thank you for that. Keep it up.
Another great video! I've been waiting all day to sit down and watch this! Thank you for the really clear and fascinating explanation of what's going on, especially with the likeness to the gyroscope, and yet the all the mystery has been maintained as well! This is why I love astronomy -- it's crackers. Rock on, Christian, keep doin' what ya do. :)
This may be a ridiculous question but hey, I'm learning. We have all been told how black holes and neutron stars rotate at incredible rates. If these massive objects ever slowed considerably or stopped rotating all together, what effect would it cause or would it remain mostly unaffected? What about the space around them? Enjoy your channel and I've learned a lot here. Looking forward to more.
Very interesting question! If the originating star had exactly 0 rotational velocity, then its angular momentum is exactly zero. Since angular momentum must always be conserved, then the object must still have an angular momentum of zero even after it collapses into a black hole. In reality however, nothing is sitting still. Everything has an angular momentum which must be conserved so if the radius shrinks, its rotational velocity has to increase to compensate. Cheers!
best astronomy-astrophysics channel I have come across. wow, you do a really great job. you are going to get very busy soon Christian with people finding this channel. keep it up.
I wonder if the K-type partner was much bigger before the supernova? Such an event so close must surely blow away quite a bit of the outer layers of any companion. (although perhaps the lightly bound mid-outer layers don't contain a large percentage of any stat's mass)
What frustrates me about graphical depictions of black holes is the consistent mistake of them looking like drains with the in-falling material speeding up and blueshifting, when in fact material should slow due to gravitational time dilation, and redshirting so that matter approaching the event horizon should appear to be frozen in space and then should just fade from view.
It depends on the black hole and the angular momentum of the star that formed it. But conservatively, a newly-formed black hole would probably spin at least 80% the speed of light.
When two black holes millions of miles in diameter begin to orbit one another faster and faster, given how incredibly huge and massive they are, wouldn't that make them be going incredibly fast? How fast would you say they are going right before two turn into one?
@@LaunchPadAstronomy. First thank you for your response! also so quickly1 also, so surprised, by clicking on the notification to me that you replied, now suddenly I'm seeing the video,. All this happening on chrome on my windows 8.1 laptop. ALL THANKS, Now I will enjoy watching this video as a freak occurrence in case it never shows again. I will try other browsers as troubleshooting if Chrome fails again. Might report results if time allows.
I'm pleased to say I enjoyed the entire video. Secondly, the video refreshed and ran fine. Clicked on the contained videos. and again very delayed initiation. BOTH: ruclips.net/video/_kywlUtQfKw/видео.html AND ruclips.net/video/VcPMLDu7BTs/видео.html .These were both from within links of THIS ABOVE VIDEO. I placed the second link in IE11 and it operated ok and a link within that video initiated ok in that IE11 . The second link of the two above sampled videos, delayed but worked fine in mozilla's firefox, also a contained link in that video initiated fine by clicking in that videos contained box... Maybe the 'ad blocker" I'm using in chrome is somehow interrupting. I'll need to investigate later.
No, not because of the black hole. It is because of the Class 2 Gas Giant being referred to as a "comet" which has been admitted to have "entered" the solar system, which probably means that its effects have become so obvious by now that they don't wznt to try to deny it or act like they have no idea what anyone is talking about anymore.
Why do all the comments say "awesome channel, great content as always" or stuff like that instead of asking or or trying to answer anything? Is the channel and the content really that awesome and great, so that people leave the channel without any doubts and a complete understanding of it's content?
Good point. It's entirely possible the black hole doesn't have a magnetic field. It could be electrically neutral so the magnetic field would originate from charged particles in the disk. However, the frame dragging would run parallel to the black hole's equator so it's fair to assume that the black hole is tilted as well.
I still cannot imagine how a Giant star would survive the supernova of its partner star. Was he Giant before? So he must have been done with his hydrogen fusion? Did the supernova only rip apart some fraction of the outer layer, and if yes how did that effect the balance of the star? How does loosing a lot of mass in such a small time period affect the core temperature? Can a Giant star, that looses too much of his mass, loose the ability for a helium (or higher class) fusion, and instantly become.. i dont know.. a white or brown or something ?
Quite a few thoughtful questions. I'll do my best to offer some quick (though incomplete) answers. Strange as it may seem, companion stars survive supernovae all the time, particularly when the two stars are initially far apart. Sometimes the supernova remnant acts to drag the companion's orbit drawing it closer in. As the companion evolves, it's outer atmosphere finds itself at a tipping point where it's free to fall onto whatever is created in the supernova. Exactly what happens depends on the specific conditions at the beginning and the specific evolution of both stars. If an evolving star looses too much mass too rapidly, it can become an exposed helium core prematurely and there won't be enough mass bearing down on the core to ignite further fusion. We call these exposed stars Wolf-Rayet stars. The W-R star essentially just becomes a white dwarf right then and there.
@@LaunchPadAstronomy These questions and answers deserves more attention than I expect it has got. I saw at least one more viewer asking the same. Thanks for the answers. And thanks for the questions.
The black hole although powerful, cannot wobble its way to a larger hole in space. God holds it back. Good luck black hole, none will be enough for you.
Thanks. Black holes continue to be a veritable cornucopia of fascinating & theory-stretching phenomena, seemingly able to provide endless test beds for *_both_* relativity and quantum mechanics. No wonder scientists focus on them so much! Your explanation was quite capable & interesting. On a side note, I do wish someone would come up with a better visualization of the idea of gravity warping space-time, than that terrible picture of the 2D plane warping into a third dimension! It's positively misleading. After all, I'm pretty sure that showing a plane - which cuts through the center of a massive body - warping *_down & away from_* said body, would actually represent *_anti_*-gravity! With today's computer-aided graphics capabilities, I wonder that no one can (or will bother to!) come up with a 3D grid, wherein the lines all warp *_toward_* the center of gravity, to lesser degrees with increasing distance (of course.) I know the old 'rubber sheet' explanation is easy, but it's so wrong! Anyway, thanks again for a very good video. tavi.
Much appreciated, and point taken on the rubber sheet approach. There are animations out there that describe the curvature in 3D, but it's hard to use those illustrations to depict how orbits happen, in which case it's back to the rubber sheet. I point out to my students that the downward direction is completely meaningless and show the same slide flipped upside down. I then tell them that this visualization is equally valid.

Light can’t escape a black hole, but a wobble can. Therefore, the speed of wobble is faster than the speed of light. Einstein was WRONG!!! The actual equation should have been “e=MW^2”. They must have already figured that out on Star Trek. ALL AHEAD, SCOTTY! WOBBLE FACTOR 9!
Not sure I agree with this explanation. You're basically saying the black hole is dragging the ether around. What if the accretion disk was orbiting at an angle to the rotational plane of the black hole, like possibly a polar orbit?
Theres no such thing as an "ether", its "spacetime", and dont think of a blackhole as an object. A blackhole is a REGION in spacetime whose escape velocity exceeds that of the speed of light. Its black because no light can escape from within the region. IF theres anything wed actually consider as matter exists inside, its a tiny fraction of the volume of the region that contains it. Odds are, inside a blackhole is an entire seperate universe with all the matter turned to energy, then back into some type of matter and it containing a volume far in excess of an outside observer would see. Think tardis, its bigger on the inside than the out... as for space stretching, thats been proven and i think helps explain gravity as a force.
@@christianbuczko1481 So you're saying that black holes don't spin, and things can't orbit black holes? It doesn't matter what's inside, the jets come from accretion disk, not the black hole. I just don't think the frame-dragging argument needs to be invoked to explain the procession of the accretion disk around the black hole.
@@willswift94 they usually have spin, its the whole region around the blackhole only that we can observe it, and the accretion disc which has visible matter is just a small part of the gravity well with the observable limits being the event horizon which is the point of no return. Basically we cant see beyond that point which is what i meant, not that its not spinning.

How did the super nova not blow away the outer layer of the near by star? Or is that why it lost its hydrogen fuel?
