Black Holes and Holographic Worlds

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.
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

[@CosmicPotato]

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.

[@blueinTN]

Totally agree!! Everything was good except that part was a huge waste of time just to show off computer imaging.

[@Neueregel]

well said

[@SKCrilly]

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.

[@RajeshUniyal1152]

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..

[@CosmicPotato]

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.

Great video I really enjoyed this one

[@diegosmarinhobr]

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!

[@baldrick98007]

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.

[@adram3lech]

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.

Dijkgraaf should've been laughed off the stage the moment he said the Earth's gravity would go up if you concentrated its mass...

[@DoppeD]

+magicstix0r I think he meant that the radius would be smaller, thus the gravity at the surface would be greater.

[@hineko_]

+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.

[@MrNick615]

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...

[@dawidex333]

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.

[@adankseasonads935]

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.

[@GZA036]

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....

[@GZA036]

+BlazeOrangeDeer lol you just repeated what caused me to ask the question. Why would only anti particles fall into the black hole.

[@TheMrCarnification]

+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

[@magicstix0r]

+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."

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.

[@colebowman2833]

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.

[@johnberner2012]

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.

[@justintodd5145]

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.

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..?

[@chrisreed7462]

yes i went in and oot of a black hole twice

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

[@SnaFubar_24]

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.

[@danielcalisto686]

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

[@Psychonaut165]

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.

[@SnaFubar_24]

@@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.
