I hope you enjoy this video! As a bonus here is a VR 360° version of the fall : th-cam.com/video/17tEg_uTF_A/w-d-xo.html For more details about the simulation : - The apparent shape of the disc is calculated using raytracing and general relativity (I calculate the motion of light rays from the source to the observer, and the apparent angle of this lightray in the observer's frame of reference) - The disc however is not simulated, I created a volumetric shader to replicate GRMHD simulations of Sagittarius A* (a GRMHD simulation would require very powerful computers and a lot of computing time). You can find an example of such a simulation here : th-cam.com/video/J8sLSQ54bHE/w-d-xo.html - The colour of the disc is calculated by converting an infinite temperature blackbody spectrum to CIE XYZ and RGB colour spaces - The parameters you see at the bottom left corner of the video are calculated analytically for a Schwarzschild infalling observer - I also did simulations for a Kerr black hole to make sure the results weren't too different (for example : th-cam.com/video/sFcnfg8KU1g/w-d-xo.html) - For Sagittarius A* we don't know exactly the value of its angular momentum yet, therefore some details about its accretion disc and the shape of its horizon might change
Can you please kindly explain in a little more detail why you wouldn’t see the entire future of the universe as you looked behind (or in front due to aberration as you mentioned) at the horizon? Phenomenal video and my absolute favourite channel on TH-cam. Thank you
Your videos are hands down the best at explaining these concepts. I hope the youtube algorithm finally recognises this so you can continue producing them.
@Cây Chanh Vàng Ok would it be more accurate if they stated this happens when you travel along the path to black hole (at slower speed, defying the gravity with some force) instead of freefalling?
@@sashabayliss5111 The gravitational time dilation effect is nagated by the doppler effect due to you falling into the black hole at a great velocity. If you were "standing" right above the event horizon then, yes, the outside universe would appear to move very quickly. However, "standing" on the surface riquires constantly accelerating against the gravitional field of the black hole. Interestingly, the abberation of light effect also perfectly balances out the distortion of light rays due to the gravitational field of the black hole in the limit yielding the 2-D ring appearance when nearing the center. Another interesting fun fact is that black holes aren't always incredibly dense. For example, the first black hole that was imaged, the one in the center of M87, is actually less dense than air!
There's something very haunting about passing the event horizon, knowing you'll never return, but seeing the spaceship you came from getting larger as if you were being given a second chance to reconsider.
person whouldnt die from spegetification itself if the black hole is a supermassive one . only smaller blackholes would kill a person by spegetification not the bigger ones
@@KobayashiBrynhild I don't think there will be a worst of best era, there will just be eras. The concept of good or bad isn't super relevant in the universe anyway. So embrace the lack of knowledge we have relative to the universe and having such a flexible ability to ponder.
In all honesty, I'm suprised they never sent chimps or an empty ship into a black hole with cameras and other things to capture data and see what happens....🤔
I've seen many videos on what happens if you fall into a black hole. I was expecting yet another focus on spaghettification, but I was learning from the first minute! This is a NEW, DIFFERENT perspective from other videos. In fact, if you watch just one video on how light and time are affected by a drop into a black hole, start with this one. The visuals were fantastic and educational.
Here is a fun fact for you: He doesn't focus on spaghettification because that only happens outside stellar mass-sized black holes. In the beginning of the video, he says it's a supermassive black hole. You wouldn't spaghettify before entering it due to its size. Unfortunately, he gets a lot wrong too. For starters, black holes only have accretion discs if the black hole is actively feeding. Secondly, supermassive black holes are at the center of galaxies and the event horizon is as wide as our entire solar system. You wouldn't see the black hole as you approached and got close to the event horizon because it's just too large. This is one of the things Interstellar got wrong, though I suspect it was on purpose as it wouldn't be very cinematic to show a giant black void with nothing else going on in the background.

14:03 Although your clock continues to run normally for you, once you cross the event horizon, an infinite amount of time will have passed for an outside observer. Which is the same thing as saying it would take an infinite amount of time for an outside observer to see you cross the event horizon. Even if you can "see" the residual image of the outside universe due to perceptional effects like doppler and aberration, in reality there's no "outside universe" left to go back _to_ once you cross the horizon. Which is the same as saying that the interior of the black hole _is_ your new universe, and any direction you might travel within that new universe will not get you any closer to the universe you just came from; you will _always_ be moving, spatially and temporally, toward the singularity.
I just want to comment that I’ve shared this video multiple times, describing it as “the best explanation of what would happen if you fell into a black hole I’ve ever seen.” Absolutely tremendous work and thank you!
Just send me in a black hole with rope and a gopro hero 10, i'll be fine Edit: Imagine if I survive and forgot to press record... I'll return inside with no rope this time
Black holes have and will still always continue to terrify me, as well as amaze me. Just the idea of going towards a black hole, knowing I will inevitably be ripped to shreds and turned into nothing more than super dense particles in the centre is frightening as all hell. Now combine that terror with knowing you can never go back once you get close enough. Imagine being in a space ship getting sucked in, and because of the limits of human technology, you cannot escape and you have to accept your fate. Which, might I add, takes a cruel amount of time before you actually are consumed. You would have over an hour of thinking.
What’s also terrifying yet fascinating is how they appear as well; they look like the blackest of black that you can get because it literally absorbs all light. Not to mention just knowing what awaits for you makes its large appearance when approaching it even more unnerving and uncomfortable. I was pretty uncomfortable looking at my screen when approaching the black hole since big things in a POV sense is kinda…odd? Makes you feel insignificantly small
I'd find a way to off myself before I got there. I know some would want to take the extremely rare opportunity to look back out and see the universe pass but the existential terror would be too great for me.
@@Trenchcoat3 Honestly yeah. The thing I'd fear more than just dying would probably be the sudden intense gravitational pull or G force you'd feel before dying. Like a 1000x strength rollercoaster drop from the stretching before everything just disappearing. But then again I probably wouldn't be able to do it, and something tells me I would just ride it out to see what happens.
Dude you wouldn't be thinking ANYTHING LMAO 🤣 you wouldn't even be able to comprehend what is happening to you. If a black hole can distort space and time, what do you think it's gonna do to a carbon based, meaty human? Be realistic. This is a nightmare none of us will ever experience..
well, this video finally helped me understand why the event horizon on a black hole looks warped on half of the hole, I appreciate the level of detail put into this!
I think it's funny how everyone says "after the horizon, there's no turning back" true...but that's the horizon for light. With matter, the horizon of no return is much much further out
The assumption for that statement lies in another inherent assumption - on our traveling at or near the speed of light. Einstein believes this is not possible or rather, improbable, but if we did (considering that our spaceship got us there to a point which is light years away), we would be at that speed. Maybe I'm horribly wrong!

@@351clevelandmodifiedmotor4 hence the disclaimer right at the start that reads it's based on calculations and simulation, aka the closest valid hypothetical we currently have
Black holes have always fascinated me. The universe itself pushed to its limits. It shocked me when Carl Sagan suggested, in Cosmos, that based on the density of the known universe, it's quite possible we're living inside a black hole right now.
Not necessarily the case. It's just not only black holes have event horizons. If you move at the speed of light, you create an event horizon behind you as the light can't catch up to you, since both of you move at the C speed. As universe expands, we have an event horizon around the Earth many many parsecs away, the veil beyond which we are not able to reach with conventional methods and physics.
This is by far THE BEST explanation of what you can expect from a black hole but also gives you a very fair explanation of what it is and how it works, I think is art! I just would like to see another video using this example and the theory of heating black holes and virtual particles.
No one knows how black holes work thats why there called theories we just know the effect a blackhole makes from the outside but no one realy knows how they work
Oh is it the best explanation? What makes you believe you're even remotely close to being intelligent enough to make that claim? Based off of what do you think you're qualified to make this statement? Something tells me you have the intelligence level of a silverback guerilla. So of course you'd say this.
Kudos to everyone who made this animation. It is so easy to understand when you see the clear picture. You really did a great job and I’m so greatful for this.

To answer your burning question about sand though…You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. You won't find that happening on your local beach: sand melts at the incredibly high temperature of 1700°C (3090°F).

I just found this channel the other day, and I gotta say that I’ve never seen a channel explain the physics as comprehensively as this one. I’ve never felt like I understand the way the universe works in such a practical way. Thanks for helping me understand the concepts you talk about. Your team is very talented, and I don’t take that for granted.
i would add a bit of theory to show you how fun it is . in fact, spaghetification would appear only if we fall in a stellar black hole wich is way more dense than a supermassive black hole ( dont dream ;) ! you would alsow die because ! i mean common men its a black hole ;), you would simply be crushed but not sphagetified if im correct) so here we are experiencing a fantastic reproduction of us falling in a STELLAR black hole ! hope you learned something new today !

I remember as a kid. My ma got a space encyclopedia for my 9th birthday. Got me hooked on astronomy. Ive lost my way in life a little but watching this made me smile 🥲 feel a little joyous just like back then
Wow I thought I was the only one. Thought I was a master by age 10 , reading about clusters and super clusters. This video makes me wanna go back in time and finish reading the remaining half
That's what I keep wondering. What if we all believe it would kill us when in reality it would send you to another dimension or teleport you through space to another planet
EDIT: Please stop with the spammy replies to this. Definitely something that fills me with dread when it comes to black holes. It's like a morbid fascination ... like I can't not ask questions, even though I know what I learn may freak me out. They are incredibly fascinating. I don't understand the space-time things, but it's still fascinating to hear about.
Well the issue is, your body would be dead. I think it does lead somewhere, but you can’t survive the actual travel through it. Like the video explained.
Your theory still works with something much less distant to us, like death. What if we are just reborn after death, into a different programmed universe galaxies away, or even over that; where life capacity is endless in space and time.
Loved your video. Others are throwing around with technical terms without thouroughly explaining it for us ordinary people. But here I felt like I finally understood how black holes approximately work.
Yes, I have always heard that once you fall into a black hole, the extremely dense gravitational force (or whatever that is called) would pull you into many pieces.
If it's big and dormant enough that won't happen until you're damn near the center. You're pulled in because every direction beyond the event horizon goes inward. You could possibly stop and look around, take readings etc, but the moment you move in any direction you go to the center. If you don't move, time doesn't move.
Makes you wonder what could withstand getting thru it and what's on the other side ? It's so hard to wrap my head around our universe knowing right know there is no end to it.....that there alone is massively mind blowing!!!!
You'd pass out before even getting close to a black hole because of the extreme acceleration. 3:21 Just look at the acceleration. It is 17125 m/s2 which is close to 1745 g's. Crashing into a solid wall while driving at 120km/s in a car can result in around 300g's which lasts around 10-15ms. There is no way any human can survive 1745g's more than a couple miliseconds.
i tried 3 "other guys" videos about black hole physics, and what one would experience through human perspective. This one explained it perfectly. No mathematics necessary, nor graphs, just beautifully-designed imagery. Thanks for the trip!
Hands down the best video I have seen on the subject. Extremely interesting, my deepest congratulations. Kudos for your amazing effort to be as scientifically accurate as possible and keep it simple and faschinating at the same time!
It's always so fascinating learning something new about this scenario. The notion of the black hole's "surface" engulfing our view as we get closer to the event horizon is everywhere and is even what happens in Space Engine, and I appreciate very much the explanation of _why_ that model is incorrect.
Actually this no longer happens in Space Engine, as the camera no longer has any real 'velocity'; The black hole will never swallow more than half of your view now. Although if I'm honest the old view is cooler.
when i was a kid, i remember reading about spaghettification as if it was just some abstract stretching of matter, hardly even considering that you're actually being ripped apart on an atomic level. that is horrifying and i couldn't even imagine how painful that would be - at least it only takes less than a second.
You probably wouldn't feel anything as it would happen so fast with so much gravitational intensity that the electrical impulses from your body would never reach your brain to tell you that you're in pain.
actually did you the speed at wich you are going when you enter the horizon ? 300 000 km/s, ligt speed friend, believe me with that speed, it would happen in a few mili seconds, you would feel nothing, just enjoy the view ;)

3:58 because we perceive color regarding the frequency of light when looking to the plasma on the left side, you would see a diferent color (one equivalent to a lower frequency)
This is honestly one of the best videos I've ever seen on TH-cam, and I've watched many about blackholes. The effort that went into this to achieve this quality is amazing, visualizing the strange nature of blackholes is difficult, but this video makes it easy.

@@KnubbelKekz You would be there to witness to the end of anything and everything. You would literally be the last surviving life, knowing that the universe dies with you.

'Spaghettification' Love it. The most complex scientific phenomenon known to mankind and our last terrifying moments when interacting with it are reduced to a pasta dish-type reference 😂
This may sound crazy but, when I was younger I had a dream I fell into a black hole. It was so incredibly vivid. I remember it like it was last night. I’ve had the dream a few times over my life and it’s always the same. When I fell deeper into the black hole I did not get ripped to pieces. There was heat but it was tolerable. Almost comforting. And it was slow. Live driving 5 mph through a empty parking lot. When I passed completely through there were stars and planets and nebulas on the other side. It was like laying in my backyard and staring up at a clear clean night sky. Except there was a huge space station in the shape of a triangle. I was pulled inside it and there were beings inside. Humans of all colors and beautiful. I remember I felt very plain next to them. And they were all tall and fit looking. Some were naked but, totally fine and comfortable with their nakedness. Some wore outfits that looked like old Grecian togas in a bright gold fabric or material. There were non-humans there as well. With multiple appendages and unlike anything you would see in STAR WARS or STAR TREK. I have spent countless hours trying to sketch them once I wake up. When I’ve showed these drawings to friends and family they even said they were unlike anything they’ve ever seen in any movie or TV show. Then one human, a male judging by his voice and physical appearance, walks up to me and tells me I’m not supposed to be here. That this is a new “arm” of the universe reserved for the worthy. I tried to ask what he meant by that but, my mouth wouldn’t work. I couldn’t even move. Then I would wake up and my arms and legs would feel heavy. Like I was covered in molasses or something. Getting out of bed felt like it took hours. I know this sounds crazy but, this is my dream.
This video is absolutely incredible and your ability to conceptualise this in a way most people can understand is worthy of applause. You’ve earned a follow from me.
I'm currently eleven years old and I'm leading to success by studying physics and science at college grade level. Now I'm starting to learn Physics with mathematics. I'm trying to figure out renewable energy.
This was honestly the best explanation that I've come across thus far, and I like that there aren't 'concrete' answers like in every other science video. Appreciate the no bluffing about what a singularity is or even consists of. Also the fact of the color of light surrounding the black hole. That makes sense, as well. Thank you!

The tidal forces would rip you apart before you got past the event horizon. Actually, since time is affected by the intense gravity, it's theoretically impossible to ever enter the center of one since time slows down the closer you get to the center. It would be like going halfway across a room. Then go halfway again. Then again and again and again. You move less and less each time and theoretically never reach the other side. It's fascinating!
@@jaynon3318 From your perspective it would be instantaneous even if it took eons for the rest of the universe. I imagine you would just get ripped apart and then that would be all you knew.

Interesting how you see the clock in the spaceship ticking slower, when time is actually flowing faster in the spaceship than where you are, as the spaceship is further from the black hole than you, and time slows down the closer you are to the black hole's gravity.
He made it so well that it feels like I'm watching a movie. This is really the best scientific video I have watched in a long time. Good job. Who else thinks this?
This has quickly become one of my favorite videos on TH-cam, one that I continue to watch a couple of weeks since discovering it. It was posted a year ago almost to the day, so that's really cool. Your narration is a pleasure to listen to, and the graphics are so brilliant that it almost makes me want to die by black hole at the end of my life. Pondering the nature of the Singularity (if there is one) brought me to an interesting thought: It's a little like life - when we are born, we cross the Event Horizon. We can never go back. People often say, "Life is short." The process of going through is a microcosm of life itself, which goes fast. The singularity represents the common truth of our existence - we have to die. This video indirectly led me to find James Beacham's videos, someone I also enjoy. This video is just brilliant!! And your descriptions of all the phenomena associated with black holes are entirely conducive to understanding them better.
@Quantum Diaming The fact that the closest black holes are about 1,500 light years away is reassuring to some degree, but the sheer power of these things and the fact that they exist even in our galaxy still terrify me. They way they can spaghettify things and eat light are what I find most horrifying. I think part of why I am so strongly afraid of them has to do with how I grew up watching documentaries and TV shows about the universe and thought of them as monsters lurking around the corner waiting to gobble everything up in their path. Who cares about the Big Bad Wolf eating three little pigs while light-eating black holes exist in our own galaxy? I think I was scarred for life lol
@@mikuhatsune184 I too, am very paranoid about black holes. Every time I hear a plane pass by, I think it’s a black hole. But then I have to remember black holes aren’t just giant vacuums, if it’s anything, black holes benefit us. Their stellar explosions that create new black holes also release carbon, nitrogen, and oxygen into space.. as well as the collisions of the black holes. The collisions spew gold and platinum. These elements make up our planet and selves. Might I even go as far as to say without black holes, we wouldn’t exist? Think about how amazing they are.. our galaxy is home to the center black hole of Sagittarius A. Without Sagittarius A, we’d be a random Solar System wandering the cosmos with no fixed orbit. Our galaxy wouldn’t even exist without a black hole.. they’re both scary and beautiful, yes.
This is the most amazingly awesome yet terrifying account of what it would be like falling into a black hole in ALL OF TH-cam. Thank you for this amazing experience.
7:19 I believe there is an error. You said the light had more difficulties reaching to us, but the light speed even if we move with c will reach us with c so it will get to us at the shed of light. The clock on the spaceship will be running faster from our point of view
This is all speculation lol. This isn’t real. 😂 (it’s cool to speculate and imagine yes) but there is no real science behind most of this. He said “while inside the black hole, we can still see the stars” yeeeea buddy ooook....
@@jackmortem4557 😂 nah bro studying and learning is what I love. I encourage it. I personally like studying TRUE knowledge though. Continue with your studies fellow
wonderful explanation, very clear and easily understandable for those who are not phisycists. to me black holes must have a function which is more useful and more creative than just attracting anything that orbits around their horizon to let them disappear like water down to a sink drain. I guess the next thing to prove is the existence of wormholes that connect two blackholes at their extremities.
The Doppler effect affects only the frequency, not the brightness, of the light emitted from the disk. The brightening is due to a separate phenomenon known as relativistic beaming, Doppler beaming, Doppler boosting, or relativistic aberration (which you mentioned later).
I believe all these effects are accounted for in the relativistic Doppler effect. Quoting Wikipedia : "How all of these effects modify the brightness, or apparent luminosity, of a moving object is determined by the equation describing the relativistic Doppler effect" Actually for a blackbody spectrum, you can calculate that the (relativistic) Doppler effects just changes the effective temperature of the spectrum. So it accounts for the change in frequency but also the change in brightness. Also, when you do the calculations in GR, all these effects are moxed together, they are not really distinct effects. Aberration for example appears only because of Lorentz transformations, i.e. saying that the light is emitted in the frame of the source. The Doppler effect appears also because of a Lorentz transformation, between the frames of the source and the receiver.
@@ScienceClicEN In that case I see no issue with the terminology, but I still think the subsequent comparison to the Doppler effect in sound waves is misleading. Most people will think of the frequency shift in that analogy, whereas the brightness change is a geometric effect.
@@SamuelLiJ I see your point, I wanted to give an analogy in everyday life, but I agree that the comparison is not exact. In fact the main difference is that sound is made of transverse (edit: longitudinal) waves inside a medium, there is nothing moving, whereas light is basically photons moving, and therefore the higher the frequency, the more photons you receive per second, and hence the more power the light has.
@@ScienceClicEN but frequency and intensity are different concepts which aren't mutually exclusive. We could have a single gamma ray photon and a concentrated beam of infrarred photons without any contradiction. The former is an example of a very energetic low intensity photon while the latter is an example of low energetic high intensity photons.
@@RubALamp Yes you are right, but the Doppler effect changes both the frequency of the photons and the frequency at which they are emitted (the temporal spacing between two photons). There still remains the cross section of the beam however, which is affected by relativistic aberration (beaming).
I think it's worth mentioning that for supermassive black holes, the point at which you would become spaghettified is well inside of the event horizon (increasingly so the larger the black hole). This is due to the following: Tidal forces (the gravity gradient which causes spaghettification) have a magnitude which is inversely proportional (4*r^3) to the distance from the center of mass (in this case, distance to the singularity, r). Meanwhile, the Schwartzchild radius (event horizon radius) is inversely proportional to the speed of light squared (c^2), which is a constant. Both increase directly proportional to mass of the black hole. This means that as a black hole's mass increases to a large value, the event horizon distance will exist at a radius with dramatically lower tidal forces than it would for a solar mass black hole.
Do not forget that the coordinate radius r becomes timelike inside the horizon of the black hole, so it does not correspond to a spatial distance from " the center". That means that the growth of the tidal forces ( and the curvature) inside, is time dependent. Whatever falls in has only a limited amount of proper time before its complete destruction happens. So, actually, the singularity is not at the center of the hole, it is something that happens in the future of the infalling object after a finite amount of proper time( at most πm in certain units) This is evident not only from the math, but also from the usual spacetime diagrams ( like the Penrose diagram), where the singularity is depicted as a spacelike surface that cuts off the future of anything that falls in.
You know I feel like you could somehow come in and with additional forces or the same removing mass technique, if the singularity isnt a single point but the same mass of a star (just more mass means more gravity) you could theoretically sling shot around it just the same. obv at MUCH more insane speeds. It's just that light coming in does not get any extra pushes, nor do an other matter than fall into it. But if you had enough lateral acceleration it would do the same as a normal Hohmann transfer.
"Our Journey ends here. For the moment, modern physics cannot describe what happens this close to the centre of a black hole..." ... ... ... ... ... ... ... ... "Hey, you, you're finally awake."
Someone once said that whilst you fall in the black hole, everything outside it moves faster, so fast that theoretically you'd see the universe die with you, I don't know if this is true but it truly sounds terrifying.
They refuted that at the end of the video. You'd only see that if you'd tried to hover just above the event horizon, but you'd quickly run out of energy trying to maintain that position.
@@evanw5572 That's not what they refuted. What they refuted was seeing the entire history of the universe. The past. What T.O.W.A said would be seeing the future. And considering that the video says everything away from the black hole seems to move faster, it checks out that you'd see the universe die with you. But you'd still need to slow down your fall while being inside the black hole. Otherwise, you'd die before reaching the end of the next episode of "Life in the Universe"
@@MorganSaph "we would observe the whole history of the universe unfold before our eyes"... "history unfold" ... while showing a clock progressing forward. They were talking about the future in the video. I can't even find any reference to that misconception even existing (seeing the past). "And considering that the video says everything away from the black hole seems to move faster, it checks out that you'd see the universe die with you." Relative to the faller, time appears to move slower for things far away from the black hole because of special relativity (moving fast towards the black hole). When did they say things seem to move faster?
I just want to echo the general consensus of how much of a masterpiece this is. I work in the field of rendering and can very well appreciate the gigantic effort that must have gone into the physically accurate yet _beautifully_ postprocessed imagery. Awesome in the literal sense!

I hope you enjoy this video! As a bonus here is a VR 360° version of the fall : th-cam.com/video/17tEg_uTF_A/w-d-xo.html
For more details about the simulation :
- The apparent shape of the disc is calculated using raytracing and general relativity (I calculate the motion of light rays from the source to the observer, and the apparent angle of this lightray in the observer's frame of reference)
- The disc however is not simulated, I created a volumetric shader to replicate GRMHD simulations of Sagittarius A* (a GRMHD simulation would require very powerful computers and a lot of computing time). You can find an example of such a simulation here : th-cam.com/video/J8sLSQ54bHE/w-d-xo.html
- The colour of the disc is calculated by converting an infinite temperature blackbody spectrum to CIE XYZ and RGB colour spaces
- The parameters you see at the bottom left corner of the video are calculated analytically for a Schwarzschild infalling observer
- I also did simulations for a Kerr black hole to make sure the results weren't too different (for example : th-cam.com/video/sFcnfg8KU1g/w-d-xo.html)
- For Sagittarius A* we don't know exactly the value of its angular momentum yet, therefore some details about its accretion disc and the shape of its horizon might change
Can you please kindly explain in a little more detail why you wouldn’t see the entire future of the universe as you looked behind (or in front due to aberration as you mentioned) at the horizon? Phenomenal video and my absolute favourite channel on TH-cam. Thank you

Fantastic mate👏🏼👏🏻👏🏾👏🏼👏🏽
Your explanations and graphics are the best I have ever seen
@@sashabayliss5111 The gravitational time dilation effect is nagated by the doppler effect due to you falling into the black hole at a great velocity. If you were "standing" right above the event horizon then, yes, the outside universe would appear to move very quickly. However, "standing" on the surface riquires constantly accelerating against the gravitional field of the black hole. Interestingly, the abberation of light effect also perfectly balances out the distortion of light rays due to the gravitational field of the black hole in the limit yielding the 2-D ring appearance when nearing the center. Another interesting fun fact is that black holes aren't always incredibly dense. For example, the first black hole that was imaged, the one in the center of M87, is actually less dense than air!
There's something very haunting about passing the event horizon, knowing you'll never return, but seeing the spaceship you came from getting larger as if you were being given a second chance to reconsider.
person whouldnt die from spegetification itself if the black hole is a supermassive one . only smaller blackholes would kill a person by spegetification not the bigger ones

Yeah that’s true. I’d be like” nah I’m good, don’t need to see the inside of a black hole that bad”.
I've seen many videos on what happens if you fall into a black hole. I was expecting yet another focus on spaghettification, but I was learning from the first minute! This is a NEW, DIFFERENT perspective from other videos. In fact, if you watch just one video on how light and time are affected by a drop into a black hole, start with this one. The visuals were fantastic and educational.
Here is a fun fact for you: He doesn't focus on spaghettification because that only happens outside stellar mass-sized black holes. In the beginning of the video, he says it's a supermassive black hole. You wouldn't spaghettify before entering it due to its size. Unfortunately, he gets a lot wrong too. For starters, black holes only have accretion discs if the black hole is actively feeding. Secondly, supermassive black holes are at the center of galaxies and the event horizon is as wide as our entire solar system. You wouldn't see the black hole as you approached and got close to the event horizon because it's just too large. This is one of the things Interstellar got wrong, though I suspect it was on purpose as it wouldn't be very cinematic to show a giant black void with nothing else going on in the background.

14:03 Although your clock continues to run normally for you, once you cross the event horizon, an infinite amount of time will have passed for an outside observer. Which is the same thing as saying it would take an infinite amount of time for an outside observer to see you cross the event horizon. Even if you can "see" the residual image of the outside universe due to perceptional effects like doppler and aberration, in reality there's no "outside universe" left to go back _to_ once you cross the horizon. Which is the same as saying that the interior of the black hole _is_ your new universe, and any direction you might travel within that new universe will not get you any closer to the universe you just came from; you will _always_ be moving, spatially and temporally, toward the singularity.

Dude, I gotta be honest, this is such a well done explanation that I'm actually thoroughly learning more about black holes
Black holes have and will still always continue to terrify me, as well as amaze me. Just the idea of going towards a black hole, knowing I will inevitably be ripped to shreds and turned into nothing more than super dense particles in the centre is frightening as all hell. Now combine that terror with knowing you can never go back once you get close enough. Imagine being in a space ship getting sucked in, and because of the limits of human technology, you cannot escape and you have to accept your fate. Which, might I add, takes a cruel amount of time before you actually are consumed. You would have over an hour of thinking.
What’s also terrifying yet fascinating is how they appear as well; they look like the blackest of black that you can get because it literally absorbs all light. Not to mention just knowing what awaits for you makes its large appearance when approaching it even more unnerving and uncomfortable. I was pretty uncomfortable looking at my screen when approaching the black hole since big things in a POV sense is kinda…odd? Makes you feel insignificantly small
Edgy
I'd find a way to off myself before I got there. I know some would want to take the extremely rare opportunity to look back out and see the universe pass but the existential terror would be too great for me.
@@Trenchcoat3 Honestly yeah. The thing I'd fear more than just dying would probably be the sudden intense gravitational pull or G force you'd feel before dying. Like a 1000x strength rollercoaster drop from the stretching before everything just disappearing. But then again I probably wouldn't be able to do it, and something tells me I would just ride it out to see what happens.
Dude you wouldn't be thinking ANYTHING LMAO 🤣 you wouldn't even be able to comprehend what is happening to you. If a black hole can distort space and time, what do you think it's gonna do to a carbon based, meaty human? Be realistic. This is a nightmare none of us will ever experience..
well, this video finally helped me understand why the event horizon on a black hole looks warped on half of the hole, I appreciate the level of detail put into this!
I think it's funny how everyone says "after the horizon, there's no turning back" true...but that's the horizon for light. With matter, the horizon of no return is much much further out
So light disappates quick than solid matter,which means solid matter would last longer but we wouldnt be able to see anything?
@@lefthandcigg4253 everything would be distorted
The assumption for that statement lies in another inherent assumption - on our traveling at or near the speed of light. Einstein believes this is not possible or rather, improbable, but if we did (considering that our spaceship got us there to a point which is light years away), we would be at that speed.

@@themightybobI’ve frequently wondered the same thing
Not necessarily the case. It's just not only black holes have event horizons. If you move at the speed of light, you create an event horizon behind you as the light can't catch up to you, since both of you move at the C speed.
As universe expands, we have an event horizon around the Earth many many parsecs away, the veil beyond which we are not able to reach with conventional methods and physics.
This is by far THE BEST explanation of what you can expect from a black hole but also gives you a very fair explanation of what it is and how it works, I think is art! I just would like to see another video using this example and the theory of heating black holes and virtual particles.
No one knows how black holes work thats why there called theories we just know the effect a blackhole makes from the outside but no one realy knows how they work
Oh is it the best explanation? What makes you believe you're even remotely close to being intelligent enough to make that claim?

Yes, I have always heard that once you fall into a black hole, the extremely dense gravitational force (or whatever that is called) would pull you into many pieces.
If it's big and dormant enough that won't happen until you're damn near the center. You're pulled in because every direction beyond the event horizon goes inward. You could possibly stop and look around, take readings etc, but the moment you move in any direction you go to the center. If you don't move, time doesn't move.
Nah, even before, the g forces will knock you braindead.
Makes you wonder what could withstand getting thru it and what's on the other side ? It's so hard to wrap my head around our universe knowing right know there is no end to it.....that there alone is massively mind blowing!!!!
You'd pass out before even getting close to a black hole because of the extreme acceleration. 3:21 Just look at the acceleration. It is 17125 m/s2 which is close to 1745 g's. Crashing into a solid wall while driving at 120km/s in a car can result in around 300g's which lasts around 10-15ms. There is no way any human can survive 1745g's more than a couple miliseconds.

You probably wouldn't feel anything as it would happen so fast with so much gravitational intensity that the electrical impulses from your body would never reach your brain to tell you that you're in pain.

Good one!
This may sound crazy but, when I was younger I had a dream I fell into a black hole. It was so incredibly vivid. I remember it like it was last night. I’ve had the dream a few times over my life and it’s always the same. When I fell deeper into the black hole I did not get ripped to pieces. There was heat but it was tolerable. Almost comforting. And it was slow. Live driving 5 mph through a empty parking lot. When I passed completely through there were stars and planets and nebulas on the other side. It was like laying in my backyard and staring up at a clear clean night sky. Except there was a huge space station in the shape of a triangle. I was pulled inside it and there were beings inside. Humans of all colors and beautiful. I remember I felt very plain next to them. And they were all tall and fit looking. Some were naked but, totally fine and comfortable with their nakedness. Some wore outfits that looked like old Grecian togas in a bright gold fabric or material. There were non-humans there as well. With multiple appendages and unlike anything you would see in STAR WARS or STAR TREK. I have spent countless hours trying to sketch them once I wake up. When I’ve showed these drawings to friends and family they even said they were unlike anything they’ve ever seen in any movie or TV show. Then one human, a male judging by his voice and physical appearance, walks up to me and tells me I’m not supposed to be here. That this is a new “arm” of the universe reserved for the worthy. I tried to ask what he meant by that but, my mouth wouldn’t work. I couldn’t even move. Then I would wake up and my arms and legs would feel heavy. Like I was covered in molasses or something. Getting out of bed felt like it took hours. I know this sounds crazy but, this is my dream.
👍
sick
I envy you for having such a great dream!
All my dreams are about me fighting someone, running away from something or strangers pooping my toilet.
At least it’s not as bad as the nightmare I had a few months ago about the sun randomly turning into a black hole and everyone dying

I'm currently eleven years old and I'm leading to success by studying physics and science at college grade level. Now I'm starting to learn Physics with mathematics. I'm trying to figure out renewable energy.
This was honestly the best explanation that I've come across thus far, and I like that there aren't 'concrete' answers like in every other science video. Appreciate the no bluffing about what a singularity is or even consists of. Also the fact of the color of light surrounding the black hole. That makes sense, as well. Thank you!
This would have been an incredibly frightening experience.

it would probably have to be netherite. an elytra and fireworks may be able to get you out, but it should be survivable with that

"the rest is filled with stars" 😢 the thought of looking across the vastness of space admiring the stars one last time as you know what horrific death awaits you is genuinely heartwrenching
Every video on this channel is outstanding, both visually and in clarity of thought. It's especially great the way basic principles are presented in very original displays. So glad to have found this channel early on, as it has the best explanations compared to all the others.
This channel deserves more subscribers! It's simply one of the best science channels here on TH-cam.
The visuals are stunning. Best representation I've seen so far.
i would add that spaghetification would appear only if we fall in a stellar black hole wich is way more dense than a supermassive black hole ( dont dream peaople ;) ! you would alsow die because ! i mean common men its a black hole ;), you would simply be crushed but not sphagetified if im correct) so here we are experiencing a fantastic reproduction of us falling in a STELLAR black hole ! hope you all learned something new today !
The tidal forces would rip you apart before you got past the event horizon.
Actually, since time is affected by the intense gravity, it's theoretically impossible to ever enter the center of one since time slows down the closer you get to the center.
It would be like going halfway across a room. Then go halfway again. Then again and again and again. You move less and less each time and theoretically never reach the other side.
It's fascinating!
Wow
So never ending pain?
@@jaynon3318 From your perspective it would be instantaneous even if it took eons for the rest of the universe. I imagine you would just get ripped apart and then that would be all you knew.
Wouldn't that depend on the size of the black hole?
Make the black hole large enough and you can cross the event horizon before being pulled apart.
@@MrCmon113 There's something called tidal forces that means unequel force on one part than another.
If I'm getting spaghettified, I'd want to see the history of the universe unfold before my eyes.
After you die, you'll see your whole life like a book in front of you

Interesting how you see the clock in the spaceship ticking slower, when time is actually flowing faster in the spaceship than where you are, as the spaceship is further from the black hole than you, and time slows down the closer you are to the black hole's gravity.
He made it so well that it feels like I'm watching a movie. This is really the best scientific video I have watched in a long time. Good job. Who else thinks this?
This has quickly become one of my favorite videos on TH-cam, one that I continue to watch a couple of weeks since discovering it. It was posted a year ago almost to the day, so that's really cool. Your narration is a pleasure to listen to, and the graphics are so brilliant that it almost makes me want to die by black hole at the end of my life. Pondering the nature of the Singularity (if there is one) brought me to an interesting thought: It's a little like life - when we are born, we cross the Event Horizon. We can never go back. People often say, "Life is short." The process of going through is a microcosm of life itself, which goes fast. The singularity represents the common truth of our existence - we have to die. This video indirectly led me to find James Beacham's videos, someone I also enjoy. This video is just brilliant!! And your descriptions of all the phenomena associated with black holes are entirely conducive to understanding them better.
Watch his other videos too
@@AverageAlien You can bet on that!!
I'm going to live forever - so far - so good !
You should watch Interstellar
5:28 - Just look at it. How both captivating and terrifying a sight is this
So your telling me I don’t fall into a pearl of singularity and communicate with my daughter through a bookshelf 🧐
The fact that it’s called spaghettification shows their frustration when studying it and deciding names for discoveries 😂
Trust me, theres much worse
This is horrifying, but fascinating. Thank you for sharing my nightmare fuel lol
Why are you afraid, when the nearest dangerous black holes are hundreds of light years away?
@Quantum Diaming
The fact that the closest black holes are about 1,500 light years away is reassuring to some degree, but the sheer power of these things and the fact that they exist even in our galaxy still terrify me. They way they can spaghettify things and eat light are what I find most horrifying. I think part of why I am so strongly afraid of them has to do with how I grew up watching documentaries and TV shows about the universe and thought of them as monsters lurking around the corner waiting to gobble everything up in their path. Who cares about the Big Bad Wolf eating three little pigs while light-eating black holes exist in our own galaxy? I think I was scarred for life lol
@@mikuhatsune184 Au contraire, I think it is mysterious. May be there is other world insinde this black hole
@@mikuhatsune184 I too, am very paranoid about black holes. Every time I hear a plane pass by, I think it’s a black hole. But then I have to remember black holes aren’t just giant vacuums, if it’s anything, black holes benefit us. Their stellar explosions that create new black holes also release carbon, nitrogen, and oxygen into space.. as well as the collisions of the black holes. The collisions spew gold and platinum. These elements make up our planet and selves. Might I even go as far as to say without black holes, we wouldn’t exist? Think about how amazing they are.. our galaxy is home to the center black hole of Sagittarius A. Without Sagittarius A, we’d be a random Solar System wandering the cosmos with no fixed orbit. Our galaxy wouldn’t even exist without a black hole.. they’re both scary and beautiful, yes.
@@mikuhatsune184 Don't worry, the creator of the universe protects you!
This was the best video that I saw about black holes, and I’ve been studying the theme for a while. My sincere congratulations.
What if the curvature of space time becomes so great that the black hole evaporates before we reach the centre
This is the best channel on TH-cam for physics. Truly inspiring.
Actually I think Sabine Hossenfelder's is, but I'm not going to split hairs about that.
This is the most amazingly awesome yet terrifying account of what it would be like falling into a black hole in ALL OF TH-cam. Thank you for this amazing experience.
Meh
"the fall will take an hour and will be fatal." that's a bit of an understatement 😂

7:19 I believe there is an error. You said the light had more difficulties reaching to us, but the light speed even if we move with c will reach us with c so it will get to us at the shed of light. The clock on the spaceship will be running faster from our point of view
This was one of the best well-put together presentations on what would happen if we fell in a black hole. Great form.

“Auuuu were goin into the black hole!”
“Jerry stop.”
“Im just kid-“
“JERRY WHAT WAS THAT NOISE?”
“Were becoming noodles, bob.”
wonderful explanation, very clear and easily understandable for those who are not phisycists. to me black holes must have a function which is more useful and more creative than just attracting anything that orbits around their horizon to let them disappear like water down to a sink drain. I guess the next thing to prove is the existence of wormholes that connect two blackholes at their extremities.
By far the best explanation I’ve seen regarding the „journey“ into a black hole. Thanks for this!
The Doppler effect affects only the frequency, not the brightness, of the light emitted from the disk. The brightening is due to a separate phenomenon known as relativistic beaming, Doppler beaming, Doppler boosting, or relativistic aberration (which you mentioned later).
I believe all these effects are accounted for in the relativistic Doppler effect. Quoting Wikipedia : "How all of these effects modify the brightness, or apparent luminosity, of a moving object is determined by the equation describing the relativistic Doppler effect"
Actually for a blackbody spectrum, you can calculate that the (relativistic) Doppler effects just changes the effective temperature of the spectrum. So it accounts for the change in frequency but also the change in brightness.
Also, when you do the calculations in GR, all these effects are moxed together, they are not really distinct effects. Aberration for example appears only because of Lorentz transformations, i.e. saying that the light is emitted in the frame of the source. The Doppler effect appears also because of a Lorentz transformation, between the frames of the source and the receiver.
@@ScienceClicEN In that case I see no issue with the terminology, but I still think the subsequent comparison to the Doppler effect in sound waves is misleading. Most people will think of the frequency shift in that analogy, whereas the brightness change is a geometric effect.
@@SamuelLiJ I see your point, I wanted to give an analogy in everyday life, but I agree that the comparison is not exact. In fact the main difference is that sound is made of transverse (edit: longitudinal) waves inside a medium, there is nothing moving, whereas light is basically photons moving, and therefore the higher the frequency, the more photons you receive per second, and hence the more power the light has.
@@ScienceClicEN but frequency and intensity are different concepts which aren't mutually exclusive. We could have a single gamma ray photon and a concentrated beam of infrarred photons without any contradiction. The former is an example of a very energetic low intensity photon while the latter is an example of low energetic high intensity photons.
@@RubALamp Yes you are right, but the Doppler effect changes both the frequency of the photons and the frequency at which they are emitted (the temporal spacing between two photons).
There still remains the cross section of the beam however, which is affected by relativistic aberration (beaming).
I think it's worth mentioning that for supermassive black holes, the point at which you would become spaghettified is well inside of the event horizon (increasingly so the larger the black hole).
This is due to the following:
Tidal forces (the gravity gradient which causes spaghettification) have a magnitude which is inversely proportional (4*r^3) to the distance from the center of mass (in this case, distance to the singularity, r). Meanwhile, the Schwartzchild radius (event horizon radius) is inversely proportional to the speed of light squared (c^2), which is a constant. Both increase directly proportional to mass of the black hole. This means that as a black hole's mass increases to a large value, the event horizon distance will exist at a radius with dramatically lower tidal forces than it would for a solar mass black hole.
Do not forget that the coordinate radius r becomes timelike inside the horizon of the black hole, so it does not correspond to a spatial distance from " the center".
That means that the growth of the tidal forces ( and the curvature) inside, is time dependent. Whatever falls in has only a limited amount of proper time before its complete destruction happens.
So, actually, the singularity is not at the center of the hole, it is something that happens in the future of the infalling object after a finite amount of proper time( at most πm in certain units)
This is evident not only from the math, but also from the usual spacetime diagrams ( like the Penrose diagram), where the singularity is depicted as a spacelike surface that cuts off the future of anything that falls in.
You know I feel like you could somehow come in and with additional forces or the same removing mass technique, if the singularity isnt a single point but the same mass of a star (just more mass means more gravity) you could theoretically sling shot around it just the same. obv at MUCH more insane speeds. It's just that light coming in does not get any extra pushes, nor do an other matter than fall into it. But if you had enough lateral acceleration it would do the same as a normal Hohmann transfer.
I understood none of that but cool
that's no different than what was said in the video
Hell yeah bruthur! Praise Dale!

"Hey, you, you're finally awake."
Someone once said that whilst you fall in the black hole, everything outside it moves faster, so fast that theoretically you'd see the universe die with you, I don't know if this is true but it truly sounds terrifying.
They refuted that at the end of the video. You'd only see that if you'd tried to hover just above the event horizon, but you'd quickly run out of energy trying to maintain that position.
If combined the two Black Hole is true
@@evanw5572 That's not what they refuted. What they refuted was seeing the entire history of the universe. The past. What T.O.W.A said would be seeing the future. And considering that the video says everything away from the black hole seems to move faster, it checks out that you'd see the universe die with you.
But you'd still need to slow down your fall while being inside the black hole. Otherwise, you'd die before reaching the end of the next episode of "Life in the Universe"
@@MorganSaph "we would observe the whole history of the universe unfold before our eyes"... "history unfold" ... while showing a clock progressing forward.
They were talking about the future in the video. I can't even find any reference to that misconception even existing (seeing the past).
"And considering that the video says everything away from the black hole seems to move faster, it checks out that you'd see the universe die with you."
Relative to the faller, time appears to move slower for things far away from the black hole because of special relativity (moving fast towards the black hole). When did they say things seem to move faster?
I just want to echo the general consensus of how much of a masterpiece this is.
I work in the field of rendering and can very well appreciate the gigantic effort that must have gone into the physically accurate yet _beautifully_ postprocessed imagery. Awesome in the literal sense!
Field of rendering you say? Like making a TH-cam video and rendering it into a video file?
Looking further at black holes is absolutely terrifying, also the fact that we don’t know too much about it… very scary
Portals to Hell. That is my only theory.
