Hello veritasium
What you're seeing in your thumbnail is a cross-section of a torrid on one side of the singularity of the toroid time Flows In Reverse and on the other side it flows regular this is the shape of the universe and we observe a flat universe because we are not the fundamental dimension of space and we have proof of Singularity inside of a convex or concave mirror and also inside of magnetism which is also a toroid with opposite spinning toroidal flows
this comment is strangely old
make a video about strange ocean stuff like the bloop. (The bloop is debunked but there's possibly even stranger unsolved mysteries)
If black hole is there , there must be somewhere like an exit so is that exit Past or some parallel universe?

As someone with a bachelors of science and physics who has studied general relativity, this is an absolutely phenomenal video; it is arguably one of the most amazing videos on this channel. Derek, you have absolutely outdone yourself! This video finds a way to communicate some of the most complex topics in all of Physics in a way that anyone can understand, many hats off to you!
Physics scares me 😨 this is why I take chemistry
@@TamWam_ You'll learn much more about your reality with chemistry, than you ever will from these Jesuit spawned mathematical models masquerading as science.
I've watched many such videos and there many amazing ones. I think the one by Alex of Astrum is even better than this one (then again Alex is a real physicist, not just a communicator).
All his videos are great. Love this guy
We are like house cats discussing calculus. We can't even imagine. We throw words around that we can understand, but we don't have brains that can comprehend.
Insane that you’ve kept 6.3 million people watching so far (after 5 days) and gotten to #1 on trending with a math heavy video with the word math in the title. It’s an educational TH-camr master class
Yeah math and topics like this are dope, shouldn’t be a surprise
Also a visualization master class. Visualizing this in this way made it understandable for people with no math affinity.
Many things help: Eistein still have a stardom fame in popular imagination, and then the title also lures with Strange - and something... something what? A weird/exotic/strange mistery around einsteins greatest work. Then that vagueness of the title +mistery +strange can also allude to way more things- like what if its alluding to something wrong or something shattering...
Sadly the kind of public interest (even more so for education) we ideally need would be one where this kind of view count would be in a video called 'the fascinating math of eistein' wich just doesnt happen
I have a severe math disability, and I'm still invested despite not knowing a single thing going on 😭🙏
@@BigDamCentral It's a surprise because of the algorithm, not because of the content

I rarely leave comments, but I have to say, the incredible effort you've poured into this video is absolutely astonishing. Your ability to explain Einstein's complex equations with such clarity and engagement is a testament to your years of dedication and the deep insights you gained during your PhD research on effective science education. The stunning graphics and your compelling presentation style kept me captivated throughout the entire video. This work brilliantly showcases your passion and the extensive journey you've undertaken to make challenging topics accessible and enthralling for everyone. Amazing job, Derek!!! 👍🏽
Excellent review for this video. So well stated, that I couldn't help but think that you would be great at writing reviews for companies. You could sell just about any company, with your eloquent way of speaking on a subject. Outstanding!!
@@GG-vv1zq Thank you for your kind words. I am unsure who would pay for my reviews lol but I am glad my approach resonated with you :)
The way he purposely misleads the answer to his own question to purposely force your brain into countering it just to properly answer it the exact way you were originally thinking about it to then add new PROPER information onto the way you were already thinking about it to begin with, so you spiral into correlating past random thoughts that directly relate to the EXACT new points that he brings up is just perfect.
Its like im being forced to use past knowledge and experiences to genuinely take in and learn the new information in a way ive never felt before.
You might be a genius.
The transition to Penrose diagram was one of the smoothest I’ve ever seen. Never understood it until now
Clearly 👍

I'm just a regular guy who wasn't exceptionally bright at maths or physics in school, my field of work is nowhere near astrophysics or something like that. I just like Veritasium, PBS Spacetime and Isaac Arthur's channels, and this was the first time I actually got to kinda make sense of all this stuff.
314 likes but I destroyed it.
It's an amazing coincidence that the event horizon acts as a kind of "black shield", shielding the events inside from the outside world, and "black shield" is literally what "Schwarzschild" means in german.
Ayo...
Extremely big language coincidence. Like how could this happen. He didn't choose his last name or anything.
E
Dude is that actually true? That's WILD
@@austinhixson625 Yeah like this a thing I would tell my future grandchildren.
It's amazing how you can see the passion and bliss in the faces of these mathematicians when they're talking about something they truly love.
As a science enthusiast , I have come across these terms white holes , black holes , wormholes , Einstein Rosen bridge etc many times and wondered about their origin.
I sincerely thank "Veritasium" for compiling this beautiful video that actually sheds light on the origin of these concepts briefly but, deeply.
Thanks a lot !
I fully expect a “37” Easter egg in every video from now on
I NOTICED THAT
And notice the episode is 37 minutes long too
yeah, me too!

@@nightelfmohawk9821 👀
As a german, I'm still stunned how a person with the name "Schwarzschild" could predict the radius of a black hole. It's such an unbelievable semantic coincident, as it basically is translated to "Blackshield"... Feels very weird hearing this, as I couldn't imagine a better word describing this phenomenon.
Simulation confirmed - lore designers got lazy with the naming conventions
superior beings were like "this humans are dumb, lets create somebody who can actually solve it, I've got a perfect name"
😳😱🤯
Yeah, and the poynting vector is the vector, pointing to the energy flux. Rayleigh scatter scribes the scatter of a light ray. It's a pitty Amalie Noether didn't proved that there is no ether in spacetime. Nomen est omen!
i thought the same thing! very certain Schwarzschild already visited it and came back and changed his name, or, he actually came from another universe. ooooooooooooh
I’ve always wanted to have a grassroots understanding of how people came up with the parallel universe theory and today you made that dream come true. No complex mathematics, just intuitive explanations. I really appreciate this
I love seeing you film the interviewee at about the 15 minutes mark. It shows transparency and integrity, and allows me to peak behind the film-making curtain.
The graphics in your latest videos top most any scientific graphics that exist on the internet. It is very hard to make graphics that are both accurate and understandable. Very well done
Well I think you should see scienceclic english.
What do you think about this graphics? 😂 And most important about an idea that black/white holes are just viewer position perspective?

White hole by definition is a "surface" where anything can only fly out of it and nothing can fall in/reach it. So when someone outside of black hole he just see like everything fall in and disappears. But when he fall in he see material can only fly out of that same "surface" he just pass through. And nothing can reach it back. Then that is a "white hole" now.
How do find this idea? :)
@@Isusia not completely true & not completely false cause you just might be right & wrong at the very same time...friend
@@hector4913Well you can't really label his hypothesis true/false either seeing as *_all_* theories on black/white hole physics are simply unproven hypothesis based on hypothetical possibilities and thus are *equally* possible of being "true" _regardless_ of how "supported/unsupported" they are due to the amount of *_direct_*_ observation/ _*_objective_*_ data_ which we base these hypothesis on being *none* precisely lmao 💯👍
It's awesome to see another of my *favorite channels* for demonstrations of science concepts here‼️
The viewers *_want & need_* an ActionLab/Veritasium collaboration 💯
"This is the simplest solution to the Einstein field equations and it already contains a black hole, a white hole and two universes" Great line.
Glory to me, the 100th like.
No bc when I was thinking of what would happen if you went inside a black hole that's spinning, before he showed us the answer, I was like "crosses into another universe through a white hole right?" But I realised it wasn't possible.
Til that reveal at the end, to be fair I think anyone would've guessed that but still 😭
And spinning at that!
Glory hole
I have a Bachelor's and Master's degree in Fluid Dynamics and specialized in trying to solve (analytically to an extent, and numerically) Navier-Stokes equations, which are one of the most difficult equations to work on. So I've had some mathematical and physical upbringing.
Having said that, I've almost understood nothing of this entire video. But at the same time, it's been extremely educational. Thank you, I think.
good luck getting that million
@@jamesnesran2348 😢
The difference between the math of a static black hole and the rotating one !!! Jeezzz.
I found this video very enlightening. Due to the visualization in your graphs it was the first time in my life I could understands more of black holes then the simple concept “if you fall in you never get out, including light”. The use of shifting grids in the visualization is brilliant.
I will save this video, so if ever needed I can share it.
I was closely following the explanation, then the spin was like "Think ya smart? Watch this!"
I’m so astonished and impressed at how smart some people are. The fact that guy mathematically said there are black holes before we knew about them is insane.
Right? I just cant fathom this
And even before Einstein, some people theorized about black holes.
@@hyefedayi5446 What a very strange comment. It is possible for him to be an utter genius when it came to physics and mathematics, while simultaneously holding horrible racist and misogynistic views. Many "great" people in history held views we would today find totally despicable. Apparently, Isaac Newton was a deeply unpleasant person. It doesn't mean we should discount his work. It also doesn't mean that his unpleasantness was somehow a virtuous thing because of his ground-breaking work, likewise Einstein's racism is not somehow vindicated by his scientific endeavours.
@@hyefedayi5446you do know there are claims that many of his pattents and works are plagerized?
There are claims he was pushed to that position for political reason, rather then his achievments in physics.
God knows best, but that does seem to be possible truth.
@@hyefedayi5446 Everyone has strengths and weaknesses. I'm sure that you know a lot about one topic but are ignorant about others. The same applies to Einstein. That's why we should always have an open mind and be willing to learn from each other.
2015: The earth is actually flat.
2025: Okay, the earth is round, but the southern hemisphere doesn't exist.
The earth is partially flat now, and Australia and Brazil disappear. Everyone's happy.
2035: so we have all the hemisphere's, but Antarctica is a ring around the planet
Flat Earthers believe Australia doesn't exist. Maybe they were right all along 😱😱
The Earth is flat, but the spacetime is curved around it to make it round :D
I mean in the west people do act like the global south doesn’t exist lol
Note @0:47, the correlative correspondence between the increased rate of flow of the fluid and the apparent compression of space and the slowing of time in the "point radial" direction. from the perspective of someone outside of/further away from that region of flow. That self-relative motion is more commonly and traditionally referred to as "acceleration" (or "acceleration-flow" in the geometry of a horn toroidal fluid vortex). The employment of vibrational waves [in the otherwise scale-uniform 'hyper-fluid medium (SUM) also known and referred to as "spacetime", to refer to and reference as "time" and "place" as a baseline frame of reference, and you have the makings of a story. This is the nature of "mass".
So we could expand upon David Bohm's "matter is frozen light." with "mass is a region of slowed time from a perspective outside that region.
7:43 I was deeply invested at this point of the video during a track meet with captions on and my device muted And when the captions say (gunshots firing) a starting gunshot fired outside and I had to double take that
I see a lot of smart physicists and astrophysicists in the comments being blown away by explaining and visualizing the diagrams, but I am just a regular guy who works in marketing and is simply fascinated by this stuff.

31:09 The thing is, singularity is a point and points cant spin so it is now kind of a ring-ularity which infinitely thin but must have some sort of radius and the radius must be different to different blackholes. This creates a whole new way of finding out about blackholes and we can also theorize that the radius of singularity must be proportional to something(maybe size of original star , size of blackhole , its mass , its age , its angular speed or maybe something else) , but i have no way of knowing or theorizing this as i am only a high-school student.
Points can spin though. Their angular velocity vectors are not dependent on its physical size.
This is amazing! Very good animated and the way Veritasium could be hyper technician and explain for dummies like me, it's awesome. We need more like this one.
This is probably the hardest thing about math. When you get this deep into math in college, it all becomes just numbers, variables, expressions, and equations. Things start to remove themselves from a tangible way of understanding.
Breaking it down like this so all of it can be consumed and comprehended in such a simple fashion while still being awe-inspiring is the most astounding things that people can do in STEM fields. People explaining an entire field like this in such a tangible fashion is so important and hard to come by.

But if you want real deep astrophysics explanations with calculus equations and theoretical physics, go see Matt @ PBS Spacetime! I could barely keep up!
@@AriefAsakura it was pretty simple
After watching this video, I have 3 questions:
1. Has anyone ever observed a white hole, if so, how? If not, where should we be looking to observe the white hole?
2. Are we living in a white hole, or the aftermath of one, or is space time itself a white hole as it is always expelling tine.
3. What if when you travel into a black hole, and get expelled through the white hole, the universe you end up in is always the same universe? Making the white hole you come out of dump you out off it some predetermined or controllable stellar coordinates. (Worm Hole). And the parralel universe is just some insnanely far off distance in the same universe.
Amazing video, and what a way to really get the mind thinking!
This is an incredible video. I’ve never understood these concepts as well as I do now. I’ve heard these things but never understood the “math”. You are very gifted in explaining insanely mind bending topics in a digestible way for mere mortals like myself. And this video is free! Incredible.

Did you know that you can use the same character for opening and closing quotes “”??
@@cslack813 Hell, I didn't even know that character EXISTED. :-) Can I assume it is just a double comma? It makes me wonder if that is the way quotes work in some language other than English. Also, just because one question mark is good doesn't mean two are better (just kidding).
You are just on the event horizon of not/understanding it 😀
I love the waterfall analogy because supercritical (fast) and subcritical (slow) flow in rivers are separated by a critical singularity in a waterfall. Surface waves (such as the ones a pebble would make) can never go up if they are downstream of the critical point, but propagate up and down in slow flow.
Im recalling, When I was a very young kid I remember when I would go to bed at night in a dark room, I would close my eyes and all of a sudden be experiencing and seeing nothing but redshift infinite expansion. As if I'm rapidly shrinking at an accelerated rate as opposed to the darkness. It would paralyze me in my bed for a moment, very disorienting and scary as hell.
i would get that too 😵💫
Fun fact as fellow artilleryman, when calculating ballistic trajectories you start by pretending there is nothing in a flat 2-d universe except the howitzer, the round, and a constant 'down'-word acceleration. From that start point of the "standard" world, you then add corrections for every error, wind speed/direction/density, humidity, your distance from the equator, the rotation of the earth, wether [sic] you're firing with or against that rotation, the weight of the round, air temperature, and most anything else that could effect any part of the round traveling. It makes logical sense to me that Schwartzchild would take a similarly empty starting approach to solve Einstein's equations.
how many did you hit.
@@trrrmac I've never missed? Missing is pretty uncommon in the US. The math is surprisingly detailed, facilitated by hundreds of reference pages of raw reference data and simple/repeatable step-by-step reference sheets you use everytime all to make sure the round goes where you were asked to put it. 🤣 Not the most fun thing thing to do manually, but it works! Plus, we have a few computer systems we use as the primary means to do the math once we're out of training which helps dramatically!
@@trrrmac A conventional unguided M549A1 155 mm artillery projectile has a circular error probable (CEP) of 267 m (876 ft) at its maximum range, meaning that half of the rounds can be expected to land within 267 m (876 ft) of their intended target. The lethal radius of a typical 155mm round is about 50m, but fragments can extend well beyond that for "soft" targets (i.e. humans, light vehicles like unarmored trucks, etc.).
So a "hit" depends on a lot of factors, not the least of which is what you're trying to hit. Troops in the open? 50m away is likely lethal to them. A tank? Unless you hit it directly, you're probably not even damaging it. A bunker? Not only must you hit it, but you must penetrate it.
This is the common approach to basically any problem that applies mathematical theory to the physical world.
Not just a run-of-the-mill grunt... They're grunts who are good at ballistics and calculus 😂🎉 thanks for your service!
I love how the PhD’s say “the mathematic equation is quite simple really.” I needed every second of this video to just grasp the idea behind it.

@@matteobenvestito9537 then is veritasium genius?
As soon as I saw the pembrose diagram, I gathered the resolve would be hexagonal.
As he said, the relativity equations can be reversed. I postulate while watching that it is an infinite grid of hexagons, where adjacent hexagons have a negative value that in their relative field are equivalent positive, "flipping" at the intersection and that is the infinite resolve.
I think the white holes are stars. So I postulate, entering a black hole would have you find yourself in the center of a sun. So to escape, yous have to be travelling at a speed where the temperature didn't burn you until you ejected. Perhaps possible with the Leidenfrost effect.
Even if that were to become possible, we'd then have to establish navigational bearings and a sustainable strategy beyond.
I would further postulate that the singularity is the true navigational point that would determine according to trajectory, which of the infinite universes you would arrive at.
my professor once introduced me a concept of what if we calculate time as space itself. you see here on Earth we always calculate space and time as a different variable, how much time do it takes to go from here to there, that's always happend right? so he came up with this concept of calculating time and space as a single variable, so basically time is space itself. with this concept in mind, I remember he was trying to simplified Einstein's theory of relativity, but I don't think I've seen the finished equations of that tho'. but honestly, with this concept, those 2D diagrams (x and time variable), that always become our sort of "boundary", can be simplified and we can add more "dimensions" to the diagram.
this is the kind of veritasium videos i live for. complex enough to make me feel a lost, but with a clear thread of intuition running through it that makes me feel like I understand what's going on. def watching this a 100 more times

White holes are better than black holes!
You’d love Floathead Physics.
Lol, it's very complex indeed. Complexity that requires a lot of studying. Then again there's a point where even the experts can't have a consensus anymore.
I got mind blown when Prof. Geraint F. Lewis said at 26:58 "This is the simplest solution to the Einstein field equations and it already contains a black hole, white hole and two universes".
This may open the possibility of things which are beyond our comprehension.
@@vedantchourey7362
Or maybe... and this _maybe a _*_big_* if... *_just_* inside it!
I'm hoping it is, tbh.
This progression of complexity is pretty common in physics. We use differential equations to describe how the Universe works. Thos differential equations can go from trivially easy to solve to a five minute exercise to a real headache to literally impossible to solve by just adding one term for each step. Einstein's equations are a set of 11 differential equations all coupled together, its a miracle we have any solutions at all

I once took a “trip” and looked to my left. I saw an infinite number of myself to the left of me in a straight line separated about a foot apart that reflected my past movements about a quarter second apart. I turned to my right and saw the opposite. An infinite amount of my bodies in a line each slightly in the future. It really made me believe that I have already lived that exact moment an infinite amount of times and will continue to experience that exact moment for eternity. Like a permanent imprint on space time itself. I’m convinced we can learn and study about our universe from certain psycho active substances because it completely removes your time perception.

This is the best, complete yet most simple explanation that I've seen on black holes and white holes. Unbelievable work. Thank you for that.
With a globe to map the need to create different projections to meet different goals is due to there being too many spatial dimensions than you have in your projection: one of them has to be flattened or essentially set to 0. It's obvious in that sense that you'll end up with things where the math doesn't make sense because the projection doesn't fully represent reality.
Seeing how even trying to run a 4d projection into 3d space runs into issues here it makes sense that having additional spatial or time dimensions might be the real reality we're trying to project. Intuitively that makes sense that some theories of quantum gravity like string theory might need more dimensions than we're comfortable with. The question then becomes is the math of the projections wrong? Or is the model / our understanding of reality wrong?
Opened this thinking "ok black holes are well-trodden youtube material and PBS Spacetime has been crushing it on the science explainers," and what could this possibly add?

@@headspace8410 Einstein came up with General and Special Relativity while he was young.
What's really fascinating here is that we can predict the universe with math. Like did we invent math or discover it?
12:55 The problem is not even about stars collapsing behind Schwarzschild radius, but about Schwarzschild equation showing that for a non-zero mass or energy density, there exists a maximum radius beyond which the black hole will form.
Even if stars didn’t compress and were made of goose dawn or were simply regions of empty space, there’s a maximum size, after which black hole will form.
Which is why it's believed that in the very early universes, gaseous regions could just immediately become primordial blackholes of gargantuan sizes, which in turn probably seeded the early galaxies
Amazing! An excellently crafted narrative arc. Thank you. Now . . . in theory there could be non-rotating black holes, but in practice there must always be some angular momentum to such an object, even if it's very small right? So then a question could be: What is the minimum angular momentum that would result in a sufficiently large space-time radius of a singularity to be, (a) observable, and (b) traversable?
Heckin' fast!
It's kinda crazy that math can predict the existence of such things without us first actually seeing them.
Yeah my mom used to count to 3.... and I knew after 3 there was an ass-whoopin'.
I was very fascinated when i first heard how, the stats of frequency and wavelength etc of any tune can give us the length of the string it came from and type of instrument it came from. So suppose you've never actually seen a guitar, you can use math to construct the whole thing on a computer. That's how scientists do a lot of deep space mapping.
@@Scorch428😂😂 👍
Yup, and the cool thing is everything is based around pure logic. Math build on it self and it all comes from simple addition, subtraction, division and multiplication. Then u need to do experiments to see if u where right with your prediction ofcourse but yea its very cool that we can predict these things, and if im not mistaken i think all of Einsteins predictions that we have been able to verify by experiments have turned out to be true…. That man was truly a genious.

This "37" minute video on black holes might be one of the best educational video to ever exist.
Are you sure it "exists?
36, the ad
37 | 73
12 | 21 (prime ranks)
144 | 441 (prime ranks squared)
37 | 27 | 73
12 | - | 21
37+27+73 = 137
12+21 = 33 (prime rank of 137)
Behold the mathematical Trinity ;)
37 -> Your inner world (Red, Thor, Animus, Conscious, Horus)
73 -> Your outer world (Blue, Hel, Anima, Unconscious, Set)
27 -> the observer (Green, Loki, No One, Subconscious, Anubis)
137 -> everything and nothing (White/Black, Odin/Freyja, Self/No Self, No Self/Self, Isis/Osiris)
(Check them out geometrically as well, centered hexagonal numbers, star numbers, triangular numbers (makes the "triforce" together), etc)
Note, 37 and 73 are hyperbolically mirrored, such that one appears larger from the vantage point of the other, one appears to wrap around the other, until you cross the "event horizon" between them, just like crossing a black hole event horizon, the horizon would wrap around you completely, appearing at first convex, then a perfectly flat infinite plane, and finally concave until the last bit of light directly behind you was gone, and at that point you have "crossed". You would never see yourself pass through, but the inside would become the outside, and the outside would become the inside, going from Spacetime to Timespace.
Thank you for your work and the video. And also for Alessandro Roussel's work !
After watching this video and many others about space, time, and physics this is my understanding (which means nothing next to those who study this stuff for work)
Gravity effects time, and the stronger the gravity the slower the time. That would mean time would crawl to almost a stop to an outside observer but never truly stop. I've been told Block Holes take the lifetime of the universe(more or less) to die. My Hypothesis is that block holes are the universes way of stopping a singularity from happening by giving the star infinite time to collapse within the black hole. This would never result in the matter being able to escape the black hole, but that's where Hawking radiation comes in. As HR falls into the back hole the removes the matter within the back hole this stops a singularity before it could form since from within the black hole the lifetime of it's existence would happen comparatively all at once. The moment things start to compress near infinity Hacking Radiation comes in and destroys it.
I know I'm wrong here and I'd love someone to explain why.

Solution:
1. There are no parallel universes. Look at the map [31:27] that is again, making the round map flat and making "new universes". It is like zooming out of google maps and keep scrolling to the right, you see more of the same countries but it is the same globe. This flat squared map is actually round and the "Parallel universe" is just the same universe but to the right (or left).
2. The "black hole" and the "white hole" is the same thing (top to bottom or vice versa). The black hole "ejects" light from the event horizon and that is your "white hole".
3. "Worm holes" don't exist - or if it does, it is just a line on the event horizon. So scraping the black hole without getting drawn in "and getting ejected" just leaves you in the same universe, just on the other side of the black hole.
Absolutely outstanding work. Unbelievable to think that something of this quality can be basically free.
I love all the anecdotes from history of famous scientists basically saying "Yeah theoretically maybe but there's no way that actually exists, no sane man would believe it, it's absurd.
And the video is about worm holes and parallel universes.

You could "take a few courses" via MIT's Open Courseware. They don't count for credits or anything (hence the quotes) but they include all the course materials including tests so you can see if it's actually something you'd want to study. It's a free test drive you can take infinitely.
becarefull is not that visually easy on math or physics universities course, to taggle that down you need skill and they need time and effort to be develop
An observer near an event horizon will get blue shift. If it’s observing another body near an event horizon and you the relativity of space/time maths become a two-body problem, but we lack observational data and new maths theory.
The shortest proof I’m aware of a counter-proof. 1/2 page of a brute-force counter example.
The 3x+1 / 2 ends as a 4/2/1 loop, but even the latest proof Fermet’s least theorem is 190+ pages of dense maths that did not exist in Fermet’s time.

The man you are interviewing has a billing way of describing complex concepts. As do you. Thank you
It's nice video.
My intuition for what it's worth is that those type of speculations apply to everything.
If you think about it, any point of the universe is a singularity, so everything that exists has one, and the horizon is the shape of that thing.
So put an apple in space and direct some light towards it, at some point it will reach the apple, the horizon, and you will cease to see that light. You don't see it going through, it just disappears and for that light, the only future is the singularity, so nothing. But this increases the energy of the apple, which might expel some light back, so now you have the white hole. It's not the same photon, the frequency will be different, but it's still the same energy in theory. So the wormhole is just the energy of the photon getting absorbed and becoming the object, which then gets pushed back in a new universe from the photon's point of view, but the same from ours.
I really think they are just trying to solve something we already know and the large scale they are using is a bit of a mirage with words that are emotionally charged for no reason. I mean, any object is called a black body for that same reason and it stands to reason it's the same.
My immediate thought upon seeing this is "But all quantum physics is strange".

The introduction is so reminiscent of the introduction to Hawking's documentary, the one scored by Philip Glass, 'A Brief History of Time.' Only in a much clearer and intelligible way, the behavior of a clock as it falls into the event horizon up to the moment it crosses the singularity. For anyone in the comments who haven't seen this documentary, it speaks a lot on Hawking's early life and his theories, though somewhat aged by now, it is still worth a watch and has a great atmosphere and score, which really makes it great fun paired with the right kind of mushrooms.

Perhaps it's simpler to say that as the spaceship approaches the even horizon, the gravity of the black hole becomes harder and harder to overcome. The result is that at the event horizon photons orbit the black hole indefinitely, forming a still image. After the spaceship crosses the event horizon, its light can't make it out anymore so it's lost forever to people outside of the event horizon. And just above the event horizon, the escape velocity is less that the speed of light though the light we see from it is very red shifted (like the light from a source that was moving away from us at a large speed, though it's not moving away, only its space time is very curved).
