- Black holes are gravitational behemoths that dramatically twist space and time. Recently, they’ve also pointed researchers to a remarkable proposal-that everything we see may be akin to a hologram. Alan Alda joins Kip Thorne, Robbert Dijkgraaf and other renowned researchers on an odyssey through one of nature’s most spectacular creations, and learn how they are leading scientists to rewrite the rules of reality.

Oh, Portuguese, please. The Brazilian people will love this channel.
World Science Festival key
This may be a stupid question, but if the information is on the horizon how do we know anything went in? Couldn't it just all be frozen at the horizon? Anybody, anybody?
I really appreciate that you've made the decision to not use interruption ads in these videos. When one is holding in for dear life trying to understand these complicated ideas, interruptions don't help.
I thoughts youtube just put them there and the creator has no say in it?
@@dejamike88 the creator can decide where to put them though
@@bruni2044 oh… I didn’t know that… learned something new today 😀
Just get youtube premium 🤷🏽♂️
@@amarjyotisarmah999 Adblock is good too, and free. But I like premium for background play and downloading.
why did i suddenly get interested in astro physics at 2am... bruh send help. i got work in 3 hours
I hope you continued to learn over the years!
same 😫😂😂😂😅😅
Two years later and I have the same problem. But I have work in two hours. Oh man
Every time 😂
Three years later........Do you still work there after a "No Show" 👀
I love Alan Alda as a moderator, he is so curious and reallly wants to understand
Kip Thorne's uuuuuh tic is my new ringtone for 2020
Kinda mean but I dig seeing ppl w tics n stims in public environments for sure 💛
@@laurenlilliewilson3646 Trust me it was said with the utmost respect and love for that man. =)
😂 brilliant
I thought there was something wrong with my computer
Something tells me you weren’t joking
I have Kip Thornes book ''Black Holes and Time Warps''. It's a fantastic read! I bought it in high school 20 years ago, and it's still one of my favorite books.
Alan Alda is such an extremely likeable personality, he has made this WSF segment one of the best ever. Excellent group of thinkers worked well together to present the subject.
i really like him as the moderator. He's clearly interested in the subject and knowledgeable enough to ask good questions
I love how Kip Thorne name-drops Hawking at every opportunity. "So, my buddy Stephen and I..."
Another technique used by someone who is lying to lend credibility to their bullshit.
Rest in peace Stephen Hawking. Your contributions to our understanding of the world will live on in our minds forever.
Forever? Until civilization as we know it ends at least. Hard as it may be to believe, there will come a day when all memory of Shakespeare, Walmart and every Disney film ever made will be gone too.
Ofcourse. One of the best minds we've ever got.
Rest in peace, guy who was just on TV and probably has less intelligence than your person.
go ask Süskind why Hawking was wrong
@@dj4lter3go so true
Damn ADD 20 minutes of watching this video while thinking about black holes, and after 20 minutes I realized my focus was entirely on my thoughts and I missed everything they said lol
+Daniel Skiba I know exactly what you mean :D
+Daniel Skiba Kudos to you for the self - awareness to realise it and the honesty to admit it. Unfortunately neither virtue is much in evidence in many of the comments here.
I've been watching this 88 minute video for hours! I keep having to rewind a bit and re-watch portions where my mind kinda sorta did the same thing. But it's worth it.
i know exactly what you mean dude :D
I do the same thing. Space has that affect I guess!
Rest in peace, Professor Hawking!
The more time I spend learning about black holes the more questions I need answers to , and therefor I have to spend even more time learning about them. So fascinating and i love the inside out ball analogy.
@SRV1 I know lol, got a lovely Martin acoustic, which is wasted on me 😂
Alan Alda is my best representative in wondering about the too difficult to imagine information that I am trying to somehow grasp in these series or other lectures. Thank you! Great panel, great moderator. Quite exceptional!
i love how long they clapped for S.H
Why ?
@@eclipsesolar8345 Why not?
I cried.
and hedidn't even stand up to acknowledge them. Diva syndrome.
@@JENKEM1000 😂😂😂
This has to be one of the most entertaining educational events of the century. Absolutely love this specific presentation and to have the great Stephen Hawkins in the audience is a great honour for all involved. Thank you so much for this treasure. Maybe that inner sphere which is blaring with the external light of the outside universe... is the place where information is stored.
I like Alan Alda as moderator. His questions may sound simple but to the point.
For sure.
Alan alda makes the conversation dumb af
Or, Andrew couldn't answer the damn question.
This video is practically Christmas come early for me! One of my 3 favorite M.A.S.H actors and science together. It doesn't get better than that.
Very nice seminar/panel. Its a tough topic to explain/understand and this was done fairly well. The drawings helped ;)
I’ve learnt more about black holes with Alan Alder’s exceptionally good questions than from any other sources. Thank you Alan!
There needs to be more content using this format.
I know that Some questions are really basic but for the people who doesn't know a bit of this topic , this video is way good from getting basic to some intermediate knowledge and for that only World Science Festival is.😊
People complaining about Alda's questions forgetting that this festival is for the ordinary average joe, not for you internet nerds who think they know, or pretend to know, the topic already.
i know that:)
here you go 🏆
Also is not easy to moderate a show with worlds brightest minds on a frontier topic
For the average Joe yeah, that doesn't mean that the moderator has to be the most ignorant on the subject. That was flat out embarrassing. I thought they they had a 6 year old asking questions. Disrespectful to the panel of experts physicists and to Stephen Hawking.
You got that right. This host keeps the tone and direction of discussion on the right path.
Man, I adore Alan Alda. I want to be like him when i get older. Sitting around, trying to understand the conversation Im having with physicists.
30.45 one of the beautiful definitions of what quantum is and personally, a very important factor in our search for answers. Came across this channel 2 days ago and am really enjoying the content. A great accompaniment to ones research and general reading about who/what/why etc we are! Thank you.
Very very good material. This host is very good in keeping the jargon digestible.
Very interesting talk, excellent and brillant experts in this domain. Many thanks.
What cool collection of people. Wish I could have been there.
This was very fascinating to watch, wish I could’ve been there live, everyone of the group is very wise and well read, and funny, if I was able to ask questions to any of these men I’d probably never shut up
What a treat to have Alan here
I showed up for the title, I stayed for Alan Alda.
Now I'm getting all nostalgic about M.A.S.H.
KIP THORNE IS THE MAN!!!
Alan alda is a global treasure.
I was born with many difficulties in my life. Although I am not fully educated, I have a strong love for science and the universe. Thank you for bringing it to me. Love you
We're so grateful for the fantastic and fascinating video, I believe in the endless super informational systems, which means endless opportunities to feel and act better for our endless limits, best wishes from Hungary :)
I am no scientist, but I can explain why that 3D interactive segment was too long for most. Its because most of you are gamers and have seen stuff like that before. He, the guy on stage, however was like a kid playing a AAA video game he liked for the first time...

That and his daughters name is “wild” 🙄. He is a little different for sure.
@@daliborkvicala1731 what is all that ?
Dr Andrew Hamilton he did look like he was loving the black hole sim he was playing on.. he also looked like giving up or going crazy a couple of times trying to explain to the host what he was on about .... I want to know what happened to the elephants that went in the black hole ..apart from not coming back
This is not going to help me sleep at 4am. Love it too much. Back another night.
Best episode in a long time great job
I'd sell away all my belongings just to have the priviledge to spend one day amidst those guys and listen to them talking and (if possible) - ask them questions! Big, BIIIIG thanks for uploading this! :) :)
Good video overall, but that portion with the computer rendering went on way too long.... I'd rather hear the physicists discuss the concepts surrounding black holes, rather than messing around with cubes and stuff. It really didn't add very much to the conversation, and seemed more like an excuse to show off some computer generated images.
Totally agree!! Everything was good except that part was a huge waste of time just to show off computer imaging.
well said
blueinTN It wasn't necessarily a waste of time. It was a visual to help those less familiar with black holes to understand the gravitational pull (that black holes don't just suck everything in) and how it visually reacts once you get something actually drawn in. There was a bit much of toying around, but I personally found that amusing, they weren't entirely familiar with the actual software themselves.
Tony Tran People who first came up with theories, were able to do so because they could visualize things...this guy's work is not waste of time...even with interstellar movie, we got a paper..
Rajesh Uniyal lol, that's not true and you're conflating different things...
Not all theories are readily "visual" and theorists don't always "visualize" things before they come up with more concrete ideas. They are driven by the maths and the foundation that other ideas. For example, general relativity has some strong visual interpretations, but it's only an analogy for the real world. You can't really show the warping of 3D space, which is why scientists always show the analogy of earth rotating around the sun on a stretched rubber sheet, which is more like a 2D model.
What this guy is doing is not the same as Einstein envision space-time as a fabric. And the point about Interstellar leading to a new paper is not the same either. Kip Thorne had equations in place already and they pumped into powerful computers to create a visual model. Even the black hole in the movie isn't a completely accurate representation. Kip and Nolan very purposefully kept a stationary view point for the shots of the black hole because a more accurate model is not easily graspable. Either way, the math and science were precedent to the visuals.
It's not a complete waste of time if the models help convey the core ideas, but this wasn't very helpful or accurate. It would have been more effective if they had pre-rendered graphics to go along with the talk, like they usually do, instead of having a guy fumbling around with an interactive program.
Also... @38:04 "parenthetically" damn, I have to remember that word! It is beautiful!
I really like this topic because, like most bottom-lines, the theory seems to point past a complicated slew of theories towards a very simple all-inclusive solution/theory/outlook
Everything wants to live where time passes the slowest. Wow, that is a really cool way to think about physics. Awesome video.
Good talk. Kip Thorne = The Physics legend behind interstellar !!
Ben Kingsley in disguise?
Much credit to Alan Alda here. He came prepared. Even brought his notebook... damn! He helped to put things in perspective for the layperson. Good guy.
Amazing Video! I love this stuff. Who else wishes they worked in this industry?
that clap felt way to long
"too"
Go fuck yourself
It's so great to hear the welcome for Hawking :-)
It’s totally amazing to see a 2 minute standing ovation for such an amazing scientific superstar. Also so glad to see that last interview with him and my mans NdT!!
Hawking didn't even clap or move he seems stuck up or better than everyone.
@@cutiepie45 If he had been physical capable of clapping, and clapped along with his own ovation, you'd be here saying, "He's so stuck up. Look, he clapped for himself. He thinks he's better than everyone."
Ya basic.
@@thangs lol it's a joke
RIP Stephen, you will be sorely missed.
Great video I really enjoyed this one
@3:40 - 3:52 poor guy... An auditorium full of people and literally no one even so much as breathed at that joke :D
I like these kind of discussions, but I'm still none the wiser, having watched them.
+Melvyn Gingell I'm pretty sure no one is and until we can perform direct experiments on a black hole on one will be much better off.
Gotta do a science
I think even the professors weren't. These "holes" are just too weird.
@SRV1 how would you know?
@SRV1 wow bro, you're the one who said "none of them get it"
Excellent questions raised by the host 👍👍
I've been reading about Kip Thorne for 31 years at least... How come the old "AAAAEEHHHH" thing has never been mentioned ever?! Do we not talk about it? :)
Same thing as a lisp or a rhotacism, you know the guy, you know it's a tic so why keep talking about it?
Hello my fellow 2D humanoids
super duper awesome content ! my man kip says "aite" a bit too much....never noticed that b4.....a new tic ?
Yeah noticed it right away
He's been doing that for a long time
Sounded more like an “euh” to me, but if i am indeed thinking of the same thing you are referencing, than yes I too picked up on that, and had never recalled hearing it prior! Just hope his health is ok
Love this. Sharing :)
Alan Alda: "it's a simple question doctor, would you eat the moon if it were made of ribs?"
Heck, I know I would. I'd go back for seconds and wash it down with a nice, cool Budweiser
i dont ever say this but great interviewer
k no because he is supposed to be there to guide the viewer along but the whole time he was just trying to understand everything and he doesn't know anything about the subject and it's annoying
All I want to know is can Hawking pass a Turing test?
Mind = Blown
Not funny.
Oners82
No, that actually was pretty funny.
Calvin Smith Fucking lol'd.
Thank you
Awkwardly awesome :)
Wow! Steven hawkin in the fucking house!
Fantastic job!
I'm wondering if you manage to get a warpdrive working, and you go inside a black whole, is there a possibility to come back out because the drive warps space? And therefore goes faster than light..?
yes i went in and oot of a black hole twice
I was surprised at what a good job Alan Alda did. He had obviously done his homework and pulled on the experts reigns when they strayed too far off the normal persons understanding.
The problem with the computer simulation was not the software, but letting the physicist loose on the system without expert guidance. There should have been an operator to control the simulation and let our panelist just describe what is going on.
You can see that he is getting more and more frustrated as his demonstration goes on and is pushing back when AA tries to reign him in.
His daughter's images were an annoying distraction from the talk.
Leslie Munday ιιι
No. He slowed it down. Most moderators are bad but this takes the cake.
Leslie, I agree. Andrew was horrible.
This was great! I quite enjoyed Alan Alda, he made it fun!
This stuff is amazing & nice 👌👌👌
Very Informational!!!
They have an interactive 3D simulation of a black hole but they waste half of the time showing cubes with some textures on them. Really?
zerospin yeaaaaa, I agree. I was really looking forward to this but I wish the guy had just made a video simulating. I feel like him spending the time on the program is rather superfluous
I actually thought Alan Alda asked some pretty good questions :/
Very apparent that the panel was not ready to respond to his questions.
45:15 finally we get some recognition 😎👏👏Yourwelcome 😌👌👌
The theoretical space/time shapes and curves that result from gravitational warping would seem to represent wave forms which would comport with the concept of gravitational waves.
RIP Steven Hawking
I was listening to random YT videos play while cooking. Had to stop and watch when they introduced Hawking; that’s the extent of that man’s influence. RIP
This in one of the funniest YT comments ever, and I don't even think it was meant to be.
My television hasn't been on for 16 days. Thanks WSF!!
my god! Kip´s head is so red and shiny it looks like a ripe apple!- I love it when they turn down the light and his head is still glowing XD
@SRV1 Probably Tourette's.
it is interesting to imagine life, reality like this, like a hologram, like a matrix. Just like information is stored to create computer, vídeo games, that create the sense of depthness, of mechanics, of light, the universe itself may be like this too. An infinite amount ou information stored somewhere forming what we perceive as time and space, creating the illusion of depth, time, etc. This is a very interesting concept, it even supports the time travel theory, because, once the information of the universe is stored somewhere, it can be recreated, if they come back to be interpreted, in the state they were before. If this is true, then future can also be created, developing the way information is stored and is affected, the upcoming information must also be somewhere stored, only "waiting" to be interpreted! the way we perceive things and the reality may be a illusion, just as the concept of space and time. All this information can be stored somewhere, in an extradimensional field. What am i saying? I don't know, just playing with my thoughts!
r/iamverysmart
think your supporting string theory, there :)
Kip has this weird tic, where he goes Uhhhaah..
he tries to circumnavigate it in the beginning, but as he gets distracted by thinking, he cant suppress it. damn @ 38:00
Joseph Chavez you noticed it too? Try sitting in a gravitational waves seminar and not wanting to make it a drinking game. There will be gravitational waves in the room after that :P
I fucking love it. IDK why. I love it.
Jack Roe if it was an edited show, they might have edited it out. I've seen shows with him, and didn't see the ticks. in this live recording, it was impossible to cover.
+Joseph Chavez Why even point this out? It's obvious. You've just demonstrated your intelligence (or lack thereof) by saying something so fucking stupid and pointless, when so many huge, thought-provoking, things were mentioned in the video. Congratulations on being a dipshit.
This is way more complicated yet more elegant, than the "mass bubble" version
Inside a black hole the roles reverse: time becomes space and space becomes time... That's fascinating!
I like this moderator much better than that wheelchair dude
+soakedbearrd i totally agree. the wheelchair dude seems to think everybody is there to watch him, he loves the sound of his own voice
soakedbearrd ...thst wheelchair dude? His name is Stephen hawking. THE expert on blackholes...PERIOD. he knows more than they do. what have u done?
He meant John Hockenberry not Stephen Hawking.
Oh, man. I laughed so hard.
@@skyjuiceification 🤣🤣🤣
Dijkgraaf should've been laughed off the stage the moment he said the Earth's gravity would go up if you concentrated its mass...
+magicstix0r I think he meant that the radius would be smaller, thus the gravity at the surface would be greater.
+magicstix0r gravity is proportional to 1/distance squared. So he is right, if you compress some mass, it's gravity on it's surface will increase as the distance from it's center to the surface decreases. Google the formula up.
magicstix0r it's a fascinating thought if you were floating in a spacesuit in space, and had the compressed earth in your hand , would it tear you apart, just stick to you, or what? Like having a billard ball sized rock of neutron star in your hand...
Well according to this study, and understanding that by your sentence you mean having a ball which mass is equal to that of the earth, it wouldn't last a milisecond due to hawkings radiation (if it was a black hole), but if it theoretically turned out to be a stable neutron star then you would get torn apart as you suspected. The gravity of such dense object would be huge.
MrNick615
He's right. If the earth was compressed to the size of a marble, it would be a black hole. But if where compressed just above the size of collapse, let's say the size of a baseball, it would still have the same gravity that earth does. If it where in your hand, it would indeed stick to you. Or more accurately, you would stick to it. However, you definitely would not wanna get any distance from it. If it where moved a hundred or so feet from you, you would be trusted towards it at great speed. If you where a mile away, it would be even worst because without an atmosphere, there is no terminal velocity.
2 questions:
1) When an object falls into the event horizon and it seems to be stuck in there completely from outside, does it get "stuck" in its "holographic information" form or its original 3d form?
2) If 3d information is related to surface area, how can you say that the most information you can have can be shown 2d? You can have 4d holographic information that is correlated to the volume of a sphere then, no? So without the need for a 4th dimension, you can conceptualize it and add the information regarding the 4th dimension. This is true if the fact that 3d world is sufficiently demonstrated in the 2d surface is because you can code information about the third dimension to the surface also.
Kip is right at 52:40. I'm inferring he is saying aim back... is to mean "to change the delta V and slow down the object so that the orbit degrades." Or to "adjust the Orbit's periapsis closer to the gravitational source by pulling the orbital ellipsis to degrade the orbit." both would be correct, although I think 1st statement. Good work on the Computer images. Helps those who don't full understand what is going on, see it in pictures rather than Mathematical.
lol am I the only one that noticed the weird hiccup sound that Kip kept making?
+Daniel Duke OMG! No you aren't :D i double watched it to be sure, but i'm still not sure what was going on :))
He has a medical speech impediment, thats all
Ravi Patel oh thanks for clearing that up
39:57 STOP IT!
If the v partials come from empty space it's self then how does the black hole lose mass/energy ? If the particles are not from it ? Is it to do with the energy the black hole expends to separate the v particles ?
The host made this very enjoyable to watch
Why does Kip Throne makes them noises?
+Rene Cu he also needs to use better sun screen
The uheeeh thing? I noticed that shit too. It's actually really distracting lol. But whatever, I have a stutter so if that's the way he talks who am I to judge. It almost sounds as if he has one too, but different.
This is the second time I'm watching this- it gets better. I noticed it alot this time, but less this time.
He does have one too, but different
Rene Cu a verbal tick?
The first speaker sounds like a super villain. Makes it way more interesting to listen too.
He is a genius.
Cheers!
Can fusion take place in orbit of SMBH? I have always wondered this because of how bright quasars are.
God damnit, when he explains what it looks like inside the black hole he does so in a way too complicated way. Just say this:
When you're inside the black hole, you don't see the horizon above you (so it's not black above you), because the black hole is beneath you. Thus, you can obviously see the light coming from the universe into the black hole, but you still can't see the light that's beneath you (deeper inside the black hole) trying to come out.
Done.
Nice summary. I agree, I'm a layman and found that particular (3d modeling) segment excessively drawn out and clunky.
But you can only dumb things down so much before it explains nothing. If one wants to understand these difficult subjects, you have to think very hard and study the subjects.
Almost sounds like earth. When we looked down we can’t see anything. When we look up at looks like a bunch of stars but that could just be light coming through the shell of the horizon.
It depends. If you were unable to accelerate to the speed of light falling in this yeah you'd see the universe outside. If you could then you would see darkness as well because light couldn't reach you.
My guess it looks mostly like a frozen image.
can’t believe I’ve never seen this one. miss you Stephen Hawking
The most profound idea was given in the last minute....
Alan is great
They said that a black hole left in total isolation would eventually dissolve due to anti-particles created just along the event horizon being sucked in and deleting some of the black hole's mass.
Question: why does only the "anti-particle" half of the virtual particle ever get sucked into the black hole, shouldn't the opposite also happen half of the time? As in the anti-mass part escapes and the massive part falls in....
+BlazeOrangeDeer lol you just repeated what caused me to ask the question. Why would only anti particles fall into the black hole.
+GZA036 you have a pair ofvirtual particles which by definition must have E=0, but one is falls from the black hole and the other is free with E>0, for the universe's energy to be conserved the other must have E
+GZA036 It doesn't matter which particle gets sucked in. The boosting of a virtual particle pair into a real particle pair requires the mass be balanced out. The black hole has to pay that mass deficit and thus "evaporates."
+BlazeOrangeDeer you is all mixed up
+magicstix0r stop the BS and read Kip's book
Alan Alda is such a great interviewer and host.. and on another note *who the hell down thumbed this 1k times??*
Those who didn’t get it lol
I for one due to its fallacy presented as fact! Its a big joke and I'm not laughin!
People who believe the earth is flat.
I love Alan Alda
I would note at min 30 speaking on happening "fast enough" can flash into existance and back out is possible "right here" because "here(space)" we have time whereas within the event horizon there is everlasting time there instead in contrastive comparison
Such a great group of minds gather together. It's such a shame they chose an actor to host rather than a scientist. End up spending the entire program trying to teach the host what the audience walked in already knowing. The audience and the viewers here lose out in the process.
I think they did it on purpose, so that u can learn with the host, they were trying to reach the maximum nr of people, even post presentation on youtube
These programs are geared toward laymen. Very simplistic in nature. I thought Alan did a fine job.
If you’re looking complex mathematics and technical jargon and advanced phd level concepts well you’re in the wrong place to begin with.
@@Psychonaut165 somewhere between 'very simplistic' 'geared towards layman' and 'complex mathematics' 'advanced PhD level concepts' is the level of complexity I usually find in content from this channel. That is not a small gap so being disappointed for the reason I expressed should not be a surprise.
