What a 'hot' video! Thanks TSA! By the way, I love the newer 'outtake' black and white parts...a little candid behind the scenes peak is fun. As always, it's great to start the day with some awesome science learning.
I've thought about black holes a lot, but for some reason I never thought about their temperature. This was very fascinating, basically black holes do temperature in an inversed way.
I've been waiting for the thermodynamics of black hole video ever since the hawking radiation one. Too bad it didn't include the second law, but I guess a full video for it will be worth it!
I’m almost 23, I do not plan on studying physics at university and I don’t need to for my career but am I going to beep watching your educational physics videos and other because it’s interesting af? hell yeah I am, love physics!!
The video is pretty cool and well explained. But I have to make a remark about what you said regarding thermodynamics. Even today, thermodynamics is mostly focused on macroscopic phenomena and leaves microscopic/atomic stuff to statistical mechanics (a complicated bastard nobody loves). I know, I know, the line is blurry and there's nothing more subjective than defining the limits of a domain in science... so whatever! Anyway, great video, loved it!
That statement is true, but only inside the event horizon. It's just that people tend to get the _impression_ it also applies to outside the event horizon, which is _not_ true.
@@ScienceAsylum Definitely. One of the coolest areas around a black hole, i think, is the photosphere. I like to imagine what it would look like to sit in the photosphere. What would we see?
Question: Are blackholes cold because time is standing almost still inside them? In other words: since temperature is motion, the motion in an blackhole just slows down because time goes slower?
Time is way way weider than that inside a black hole. Inside a black hole time and space change places so you have three dimensions of time and only one of space.
It has nothing to do with time. "Nothing escapes a black hole" -> really 0 temperature, because it emits nothing. The hawking radiation is a weird idea, you should check Nicks other video. The short story is: the effect is really, really low (still unproven btw.) and therefore the black hole doesnt "emit" much.
No. Temperature is how they transmit energy to their environment. Motion is just one easy way to do it by kinetic collisions. But it can also be done through radiation, and other ways. But black holes don’t transmit ANYTHING to their environment. By definition, they are perfectly cold, they cannot heat up anything. They are absolute zero. Except Hawking radiation… Also, as stated in the video, they can be hot in the inside, they just don’t release it until the end of their life.
@@XEinstein That's a bit misleading. Yes, space becomes "timelike" and time becomes "spacelike". However, time still marches forward for the local observer, and objects still have volume (3 dimensions). In fact, nothing interesting happens upon crossing the event horizon except the view.

Black Balls in Space! XD I liked that line when I first heard it in the Black Hole VIdeo a long time ago. Also, the IR thermometer is one of the best scientific instruments I have ever used. Beautiful Video btw.
You make it seem too easy a topic :) The only stutter I had was because of the graph plotting wavelength, and thus hotter things were to the left and colder ones to the right. But the graph redeemed itself: the extreme squeeze to jump from visible to black hole frequencies really put things in perspective
Good video Mr. Nick. Loved the timeline part. It would nicer if you mentioned the fact that S-U graph for a BH are concave up unlike "normal" matter with concave down shape. The shape of the graph nicely explains that as energy is added to the BH it's tendency to absorb energy increases, which corresponds to cooling down.
I remember reading a student joke about the "temperature of hell", reasoning that a thermodynamic system like hell should either expand faster than the incoming amount of souls, therfore cooling or heat up if the expansion is too slow to counter rpessure building up due to the added souls. But if we take a black hole model for hell, which may be a bit more insteresting on a theological level, these findings are exactly reversed... ...and it would proof that Satan is in fact the coolest in the universe B|
@@Bomba_drastic What I mean is that a black hole is really a star with tremendeous gravity. it has the same characteristics as a star in other regards.
Well there's just a big difference between the way a star and a black hole behave. The objects that are close in mass density to a black hole are neutron stars. And even though a neutron star has incredible mass. It behaves a lot more different than a black hole and some even argue that neutron stars aren't stars either since it doesn't undergo fusion anymore. And in this video you also learn the temperature is very cold where all the stars are hot. And we all know light doesn't escape the black sphere trapping it inside hence the name black hole.
Isn't this actually the temperature of the event horizon? If Hawking Radiation occurs at the event horizon then the singularity causing that warped space-time could potentially be a different temp... Which we of course could never know as that information cannot escape the extreme curvature of space-time. Perhaps a nit-pick?
Time should not flow beyond the event horizon, so there should not be a temperature. And you also cant enter an event horizon. You can only get squished around it, and become a part of it/expand it that way.
@@sanmar6292 As far as we can apply the same rules to the inside of the black hole time still flows inside. It just sort of switches places with the space direction towards the singularity. The singularity becomes a point in the future. And you can absolutely enter the event horizon. For the infalling observer the event horzion isn't necessarily anything special. There is no physical boundary there, so you can just cross without anything bad happening. You just can't go back. And nobody _outside_ will ever see you cross. They will see you get redshifted until you merge with it.
I have a question that in thermodynamics we come to a conclusion that perfect absorbers are perfect emitter. Is it true for black holes too? Because to me blackhole seems a perfect absorbers but not perfect emitter.
the black balls and pumping out radiation ..eating all surroundings ,yet follows all law of thermodynamics ..And shivering ultra coooool..yeahaa...chilled out !thanks .
Nick, a request: Whenever you proclaim _"The conservation of energy shall not be violated,"_ I request you to put a starred footnote stating that sometimes, it _is_ violated. In your earlier videos, you yourself have pointed out situations where energy is _not_ conserved: - Expansion of space - Heisenberg's Uncertainty Principle
@@markvalkrin3128 🤣 Dude, every law holds if you limit its scope appropriately-Newton's Law of Gravity, Maxwell's Electromagnetism ... even Aristotle's Law of Motion, which says that every moving body eventually comes to rest! Hence my request for a starred footnote. Also, what do you mean by 'local scale'? It doesn't hold at quantum scales. The constant creation and annihilation of virtual particles violates conservation of energy, but is allowed by Heisenberg's Uncertainty Principle. In fact, all three fundamental forces in the Standard Model _require_ it. (But I could be wrong-I don't know what QFT says.)

"Black Balls in Space" sounds like it would be an adult parody to Mel Brookes' :Space Balls"... No disrespect to the great information presented by Nick!!!
When i read about hawking radiation first time from hawking's book, it said that the radiation has something to do with one of the counterparts of a particle antiparticle pair which manages not to fall in whereas its partner eventually ends up inside the BH, can someone tell me what Nick is referring to...when he says extreme radiowave frequencies are emitted by black holes?
It's because the particle explanation is false, Electromagnetic emissions supposedly from the hole are actually at wavelengths that correspond to the diameter if the hole. So small holes have high frequencies and large holes emit at longer wavelengths, ie lower energy emissions, thus very cold and slow emissions , whereas very small holes emit xrays and evaporate very quick.....allegedly
@@ScienceAsylum (09:01) Would it be fair to say that the Universe cannot be a black hole, amongst other reasons, but also because any 3D object would become dissociated, due to the inability of the information to climb back from the particles that are further "down" towards the particles that are slightly behind, effectively breaking chemical bonds, atomic bonds...?
There's thinking now that Blackholes might not completely evaporate. They may hit a wall once they get so small, but there's no way of telling until a theory of quantum gravity is reached.
That's certainly been _suggested_ ...but we don't know how black holes behave when they're that small. It goes beyond the scope of the Hawking radiation prediction.
What? What? Whaat? Black holes get colder when they absorb energy and hotter when the emit it? Mind blown again. I like how you were careful not to cross the horizon. Good job. None shall pass!
As an ex-pat from the UK I thought I felt cold until I moved to Canada. Their winters are cold! When the moisture in your nasal cavity freezes going outside, then it's pretty cold. Although due to Climate Change? Parts of Canada are experiencing unusual temperature swings compared to other locations in the World. I went back to the UK one January and it was "worse" there than the Winter in Canada.
So what your saying is someone falling into a BH will freeze instantly as soon as it touches the event horizon. So instead of getting spaghettified, it can become fine dust of falling particles.
