So what happens when two Super Massive Black Holes collide? We may be about to find out, because astronomers have spotted a pair of them in a close binary orbit for the very first time.
This episode of Space Time Journal Club discusses:
"A candidate sub-parsec binary black hole in the Seyfert galaxy NGC 7674", Kharb, Lal & Merritt 2017

In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow. This paper was just published in Nature Astronomy by Preeti Kharb and Dharam Vir Lal from India’s National Center for Radio Astrophysics, and David Merritt from the Rochester Institute of Technology.

the best part is always seeing how you figure out to end on "spacetime".
I totally agree! And I love it!
I, too, love
Spacetime.
Class: "Say the line, Matt!"
Matt: "...of spacetime"
Class: "YAY!"
Imagine the precision of radio interferometry with stations placed on the moon combined with the stations placed here on earth
MidnightAmratha bnbn
you
I honestly don't think we'll ever serious go into space in the next 100 years. when the moon landings occured we had a chance to basically turn it into the old west and just explore but we decided to invest in nukes and at this point that kinda involvement from the public and the money won't be there .
think buck Rogers and commando Cody and flash Gordon we shoulda just been making the tech nonstop but alas we prefer greed and fantasy to investment and reality.
look at airplanes the first one was godawful now we got a stealth bomber that can swoop the whole planet in about 4 hours.
we shoulda put that kinda effort into it.
@@findantu sadly any country with enough wealth to put into that level of scientific advancement is too busy protecting that wealth by investing most of it into their military
@@findantu We're actually at that point now because countries like the U.S. are in the process of privatizing spacefaring operations, and the result will be far more commercial.
I visited NYC there a while back, and honestly the best part of that trip was at the Science Centre when in my wandering I walked into a blackroom and then randomly heard Matt's detatched voice speaking to me about black holes.
Matt is definitely getting revved up, and episodes get emotionally moving. That's really good, you're the best, Matt!
So I'm subscriber #1000000. This just became a super-massive channel.
hey thats me don cheat u little fuck
There were probably several
"only 1 light year apart"
well, when you're multiple light years across, one more isn't much. it's like saying "only a foot apart" on human scales.
Much closer than the distance between the sun and any other star; on astronomical scale it's very close
I'm just glad we don't have a SMBH 1 lightyear away from us :D
In terms of cosmic distances, that's like the distance to your next-door nieghbors' house. :P
Its a long way away but those fuckers are hUGE
Sometimes I wish quasars could just talk it out like adults.
They are just trying to get together. Why are you against two quasars in love?
I Identify as a Quasar
Whirling about violently and expelling a mass of hot gas? That's how adults around here talk things out.
wrg, talk it out is not adults or not. do anyx nmw, can fight etc.
Don't get involved. You'll wind up being labeled as the bad guy and neither of them will talk to you.
Congrats on 1 million subs. Love the channel!
It's 2 million now, i'm from the future
This channel deserves more subs than pewdiepie!
I feel like "When Quasars Collide" would be a really good romance title for some reason.
Hex Hexom Two smbh's penetrate each other in super hot binary frenzy.
John Lacy Exactly, rated R romance
lol its funny coz in futurama they had a romantic episode where there was a quasar
Neutron star collision?
"when matter and anti-matter collide"
a tragedy romance story.
A galaxy sized LIGO sounds reasonable. 👌
Let's build it! 👍
I'm in.
Simple enough, it uses neutron stars throughout our galaxy as the detector. All we need is to keep track of them, it should be online within a decade or so.
Wait a minute, Asimov
To build it we need a lot of LEGO...
It's all actually covered by Trumps tax reform.
God I love this series. Thank you so much for everyone who can support this channel. I get all giddy when I see a new space time vid
I just got home from a public lecture (in Maastricht) about Erik Verlindes theory of gravity.
I hope that PBS Space Time will do a future episode about entropic gravity.
erik2000 gravity is the distortion of electrons forming electric dipoles.
u wot m8?
Entropic gravity is interesting but one problem with it is that it needs a preferred frame of reference for all that protein-like entropic work to happen in. This makes it hard to reconcile with general relativity.
Nah. We already heard about modified Newtonian dynamics. Dark matter is just too good an explanation for the phenomena we observe in the larger universe. Also, entropic gravity looks like it might be inconsistent with some observations ( arxiv.org/abs/1706.00785 ).
Dark matter is invented because they wont factor in something as simple as electrical energy. YOU CANNOT CREATE MAGNETIC FIELDS WITHOUT ELECTRICAL CURRENTS.....take off your blinders, electrical energy holds galaxies together and explains their motions.
I have never been so hype for a merger! Thanks for the amazing content!
Curiously there's an app; Appygeek it's called, and they are good at providing you with updated science and technology articles. There was an article about this on there, and they'll probably continue to update. 👍
Git: Merge conflinct
This is honestly the best show on UA-cam.
i love quasars - they are my fav object - if i think about them for more than 5 or 10 mins i get utterly awed by the numbers and my head explodes...
I made cooked pudding today and didn't burn it.

1:44 The meme "I came with the power of a thousand suns" has forever lost its grandeur.
Being myself a physicist, I can agree with the advise given to younger ones who are interested. And be prepared: it would take a lot of math. So much math that it's too much for many people. And remember: the school math and physics is a joke compared to the university program. If you excel in math at school, you may still be overwhelmed at the university. Therefore use every opportunity to improve your knowledge before it gets too late (like, 2 days before the exam).
I love the bit of pwnage at the end.
love the narration as much as the subject matter.
I always hated physics, and most of that hate was based on the fact that I couldn't ever focus enough on what the teachers were saying.They used only the "write here, talk a bit about it there" approach and because of that I couldn't EVER care to get interested enough to focus on what was being taught.
That said, PBS Space Time videos made me want to learn more physics.You guys talk about it, show how it is or how it should work, give image and/or what's necessary to make people understand what you're trying to teach.
If schools taught like you people do, I'm sure a lot of kids would be more open to learn physics and other subjects like chemistry or mathematics.
Every part of this video is mind-blowing.
Again a very clear and fascinating explanation. Thank you.
Dear PBS Space Time,
Is it possible to do a future episode about the Kardashev scale?
Yours faithfully,
Erik de Wilde
erik2000 they've touched on it in earlier episodes, but they've never covered it explicitly. Would be cool, but idk if it warrants an entire episode.
for a moment i thought you meant the kardashian scale.
glad i got that wrong.
If you're interested in the topic (and not in the take on it by PBS specifically) you could try Isaac Arthurs and Fraser Cains channels. I think both had it covered
This^
John Michael Godier touches on it quite a bit as well
Holy shit. They written it a Mile away from my home in India. I had no knowledge of this kinda research going on. Damn it
Thanks
Very good quality,as always.
Thank you Family that is beautiful, peace and love, Doug:)
The 'μ' in question was not a super- or subscript, it was just a factor. Someone left out the '_' or '^', whichever was needed.
THIS.
That's right.
This was really interesting to watch considering now that we've detected dozens of these. With this whole new way to observe our cosmos we can detect things we've never been able to before. The first merger between a black hole and a neutron star has already been observed. What an amazing time we live in!
Amen to that, brother! And now humanity is reaching out our collective distant, yet steady hand once again to explore the known and the unknown in our universe like never before, of course I mean with the currently-on-its-way-to-L2 James Webb Space Telescope after all of those years of the indescribably difficult and creative work the world's best scientists and engineers put in for the advancement of all humanity.
Exciting times indeed, if not also bizarre and uncertain lol.
*You*-yes*You* yourself have " detected these things have?
No, I rather though not, all you are doing is repeating " teacher says" are you not?
When you use the word " we" for all practical purposes you are saying " I" whether you like it or not, and when you say you*-yes you* sunshine have not detected anything, so that is not exactly strictly true , is it? There is a word for those that say things that are not true, and I suppose religious will embrace that adequately, but no matter, " teacher says" these things, and like good credulous little child you accept everything and anything that " teacher says". You yourself- yes*you* titch, have never " detected" anything of the sort have you?
It'all right, you can say, I know that perfectly well. " we", my arse!
You guys provide a lot of great inspiration for writing sci-fi.
Hahahaha, that ending was great :-) keep these awesome episodes coming!
Matt, I didn't say anything about superscript or subscript. On the video there is W\mu instead of W_\mu (or W^\mu, for that matter). It is just a small typo, nothing like what you said. But that's a nuisance :)
Yes you're right: the symbol \mu was written directly on the line, not as a subscript. An underscore is missing in its LaTeX code :)
Oops! I see what you mean now. Apologies for the misinterpretation, and for the LaTeX fail.
PBS Space Time no worries, just trying to help an amazing channel :D keep it up!
I wish UA-cam comment threads were easier to follow. This thread now spans three videos, but it's nontrivial to search for a comment in a single video, much less connect them across videos. Maybe Google Wave was shut down too soon after all.
If it was a typo, then it can be easily fixed.
Do a video explaining the Navier Stokes equations and why they're so hard to solve. Also one on what entropy is. I find entropy to be a very hard concept to understand, especially its mathematical form.
Congrats on 1 mil subs. Definitely deserved!
My teacher's motto is "I don't want to believe,I want to know" and I agree.
As a little kid I learned about black holes as things catching everything nearby and not letting it escape, so naturally my first question was "What happens, if two black holes meet each other? They cannot not escape each other, only one can escape the other, right?" Looking back now, this question seems too funny to me :)
(Though my teachers never attempted to answer this question...)
I have to wonder if scientists lovingly refer to SMBSs as sumbitches. That's what I think every time I hear it.
Do you mean SMBHs?

Okay then I believe you
I see what you mean
Hanging out in the Null Point between these monsters of gravity would be a hoot!

4:35 gosh they found a giant xbox controller in space. AWESOME
You've seen reality. We are all part of your Xbox simulated reality.
I wonder if the rubberized grips stay in place, though.
#PBSspacetime please make a video about how the electron degeneracy pressure holds up the metalic core of a dead-non neutron-star , and why some neutron-star cores can't heat enough neutron degeneracy to win from gravity

Dropped "Pulsar Timing Array" on us then ""More on that at another time". Better be next episode. ☺
great work
3:29 So, since we are looking back over 400 million years, then it's possible that this merger has already occurred some time ago?! Cool!
magnummax78 everything you see occurred in the past.
and we are waiting for the electromagnetic and gravity wave pulse to arrive, yes.
Mike kirock No we arent. Its going to take millions of years on the minimum. We're going to be long extinct by then.
@@rykehuss3435 wow are you from the future? Dang! Tell me more
TheDarkToes Do you know what evolution is? Humans (Homo sapiens sapiens) are going to be extinct by then. Either we destroy the planet's habitat, nuke ourselves, an asteroid hits, or we just evolve into a new sub-species. In either way, humans as we know it wont be around.

"About to merge." Won't move noticeably closer to each other before everyone watching this video is dead.
In an astronomical sense, it is very close and closer than anything we have seen so far.
*before every human on the planet has been long dead, is more likely.
Well, that galaxy is millions of light years away. For all we know, they may have already merged...
Nice to see someone was paying attention.
well they said they were 1 light year apart. it could be feasible for us to see it happen.

I speak English, but i don't understand. ...yet i keep on watching these. ..
Do black holes merge when their event horizons cross or when their singularities merge? Also, are event horizons perfect spheres? because the animation of two black holes merging showed their event horizons stretching towards each other. This confused me because if the mass of a black hole is all concentrated in a singularity, doesn't that mean the event horizon would be in equal distance in all directions, making it a sphere? And how can singularities merge in the first place? wouldn't they just keep spinning faster and faster, never being able to reach each other because they are defined as points, which cannot occupy the same place because that would imply they have volume... SO MANY QUESTIONS!!!
1 and 2) There is a notion of an event horizon as a "trapped surface", where anything inside is doomed to fall into the singularity because even at the speed of light it cannot escape. When two black holes are about to merge, a trapped surface reaches out from each black hole and connects them. The moment they touch is called the moment of the merger.
3) The singularities do meet up, quite rapidly. Newtons Laws would suggest that they would just orbit each other, but in General Relativity, there are no orbits close to or inside a black hole. In fact, the singularities are impossible to avoid once inside. They are stronger gravitational attractors than anything in Newtonian gravity. :)
Question: what about time dilation inside the event horizon? Is it possible that the singularities never merge? I remember reading about imagined ring shaped singularities in rotating black holes. If neutron stars can rotate with thousands of RPM (surface speed of 25% light speed), orbiting singularities should be even more extreme, so even if all possible futures inside the black hole ends at the singularity, it could possibly take an infinite amount of time for the singularities to merge?
No; this is due to relativity. Inside the 'photon sphere', about 50% larger than the event horizon itself, an object would need to orbit faster than light. As such NO stable orbits exist closer in; anything there must spiral in to the center at some rate. As such even a singularity orbiting another at light speed will merger with it in a certain period of time, a very short one too.
+watsisname The way you worded all that didn't match how it really is. Speed of light is not the actual speed, that is just saying that light can't escape, it doesn't need to have any speed, no matter how fast it is going it is still getting sucked up into the multiverse's strongest Kirby. xD
Also everyone in this section has no clue how things works around here, one of you guys sounds like you are saying that the singularity is bigger than the event horizon.... The event horizon is never the same, there are different ones out there.
what will be the result of these SMBHs merger? what gravitational waves they will produce during merger in comparison with the events already registered by ligo?
The waves will be very powerful, but also low frequency, they'd be more like tides than the quick wriggles that LIGO can handle.
At 4:38 the image that shows radio image of the quasar binary, credit says TIFR-NCRA, It is an Indian institute (Tata Institute of Fundamental Research - National Centre for Radio Astrophysics). I wish that the narrator should have mentioned about their contribution also.
Thanks! @4:36 - looks like a game controller! :O tavi.
Love these videos. They are fantastic. Do you think LIGO will detect a disturbance in Space Time if your SMBE (Super Massive Brown Eyebrows) ever merge? Keep up the great work!
LOL! :-)
Those eyebrows are creating incredible tidal forces on one another, at some point as he ages, the curvature of space time may effect his vision as gravitational lensing occurs.
Kevin Harris
Your comment nearly made me pee my pants! LOL! :-)
Galactic Black Holes would be a better name.
One hypothesis about Seyfert galaxies is that they are just as powerful as quasars (around 10^38 - 10^40 W), but the difference is that the jet of the quasars is pointing towards us, while the jet of Seyfert galaxies isn't, which makes them look much dimmer
HAPPY 1 MILLION
Whenever I want to feel stupid, I just come watch these videos.
do more quantum mechanics and quantum theory
pls more quaNTUM physics or pbs qauntum pls make it
You should watch the Looking Glass Universe channel. She doesn't have the same budget and is too busy with her PhD program to post regularly, but the content that's there on quantum os fantastic. Better than this channel. Matt's expertise is really astrophysics. He can do quantum, but it isn't his main thing.

#PBSspacetime Question, so the magnetic field generated by the accretion disk of a supermassive black hole permeates the space around it. What happens to magnetic field lines that cross the event horizon? Magnetic monopole?
The magnetic field that we see in Quasars is produced by charged particles accelerating around the black hole Outside the event horizon. Once the particles fall within the event horizon their creation (w.r.t us) of magnetic field lines ceases to exist. At this point it doesn't matter if the charged particle is still producing a magnetic field, no photon created by its energy can escape, so effectively the magnetic field inside the EH is meaningless to us.
Great question
I think that the field lines would be twisted and snapped close to and at the EH, but intuitively, I think the information of the field's properties are preserved, allowing it to be contiguous.
Charlie22911 Good question!
Neutron stars produce strong magnetic fields by rotating. How about the magnetic field of a rotating BH which has a tiny bit more mass than that of neutron star (which is below the critical mass for a BH)?
Just about to break 1 million! Keep up the fantastic content!
Congratulations with 1 million subscribers!
13:15 - 13:38 = Best comment rebuttal in the history of Space Time :D
Would like to learn more about Pulsar Timing Arrays. Sounds cool
Hope they cover it. You basically use the galaxy's neutron stars as a set of very precise clocks. By tracking them you can tell if their distance from Earth has changed slightly due to gravitational waves.
Its genius!

I think what Rubbergnome meant was that it should have been a subindex ( W_{\mu} ) instead of just concatenated ( W \mu )
It just dawned on me that we are detecting black hole gravity waves within the core of the audible frequency range 10Hz to 10kHz. How does that work out? Is there potential for a black hole to be audible if it were emerced in a dense gas cloud or induce resonance in certain circumstances?
Gas have to be pretty dense to carry sound, remember the doorbell in the vacuum jar from elementary physics that goes silent when nowhere near a good vacuum is drawn? So you'd have to be unhealthy close to the black holes to hear anything and the gas and you will possibly be plasma at that point. Also the gas can't fall into the black hole at a speed greater than the speed of sound if you want to hear it.
Gravitational waves could not be directly measured in electromagnetic frequencies. Extremely sensitive laser interferometers measure subtle changes in the dimensions of space. The space between gas particles would compress and expand, but in such a minuscule way that the amount of energy transferred would be overpowered by random background noise. That's my interpretation anyway, I may be wrong.
You can't hear electromagnetic waves with those frequncies, right? The only reason you can hear sound is because our ears are air pressure wave detectors. Those waves are waves in the very fabric of reality.
If you could record them, and then translate them to sound though... Maybe.
Marik Zilberman
Obviously particulate matter is not moving in relation to a static location in the traditional sense, but it is moving in relation to itself and the space between matter. If this movement is capable of creating collisions with a material dense enough to transmit kinetic energy it should produce a wave of energy. It really comes down to the physics. Does the space time wave have enough energy to transmit into kinetic motion?
Two large, dense, groups of particles are moving through normal space and are on a collision path when a 1000Hz gravity wave passes through their location in space time at the moment collision begins. Is the collision of the particles linear or does the space time wave produce a resonance as the collision is slowed down and sped up?
If it does, I presume we could call these particles air. Air as we know and love is very energetic. Therefore if we were submerged in said air, and for the sake of argument/scientific understanding, within any hypothetical distance from the source of the gravitational wave, where it would have more energy to transmit, would this produce a sound wave?
Gravitational waves can transfer energy to matter via the 'sticky bead mechanism'. The transfer, even to solid matter like the Earth is low (Gravity is weak) They're also quadripolar waves rather than pressure waves like sound. This means that the energy transfer tends to go into heating a material rather than propagating bulk movement on any scale.
However if you were close enough the difference in energy imparted to solid vs less dense forms of matter should create sound waves. However at that distance your body,nerves and brain would also have energy pumped into them and their structure stressed, which might make the experience... uncomfortable.

For a black hole, either it's not massive enough to be stable or it's massive enough to destroy Earth
It doesn't have to be stable though. I do agree that some descriptions are on drugs though.
If it's not stable it literally blows up, not good for protecting your trainer either way.
We have the most adorable scale model of the solar system along the cliff paths of our town and when you said that the SMBH would cover most of our solar system I thought of it in terms of that and finally got an actual idea of how big these things are...and.. I have no words. That's incredible.
Like earth is about the size of a bead where as this thing is about the size of the school grounds near me.
And if it's really most of the solar system its basically the size of my town 😂 now that I think of it

Thank you for the response. You're of course correct, it's just that due to the size of outer space large distances clearly become matter of fact but are still huge in the scheme of human size :)
Ty6260 "Overpowering lightspeed with gravity" did you get that sentence from a gibberish generator?
Rykehuss Yep.
Think of it that way: That's closer then the next closest star to US.

In case you clicked this video wondering how to make an apple pie, here is the recipe:
Ingredients: 1 recipe pastry for a 9-inch double crust pie, 1/2 cup unsalted butter, 3 tablespoons all-purpose flour, 1/4 cup water, 1/2 cup white sugar, 1/2 cup packed brown sugar, 8 Granny Smith apples - peeled, cored and sliced
Directions: Preheat oven to 425 degrees F (220 degrees C). Melt the butter in a saucepan. Stir in flour to form a paste. Add water, white sugar and brown sugar, and bring to a boil. Reduce temperature and let simmer. Place the bottom crust in your pan. Fill with apples, mounded slightly. Cover with a lattice work crust. Gently pour the sugar and butter liquid over the crust. Pour slowly so that it does not run off. Bake 15 minutes in the preheated oven. Reduce the temperature to 350 degrees F (175 degrees C). Continue baking for 35 to 45 minutes, until apples are soft.
How does a blackhole absorb "gases from a surrounding galaxy" if space is a vacuum?
Listen, if you're going to bring up a Pulsar Timing Array (PTA) and not talk about it; then I guess I'll go back to watching Nicki Minaj videos.
