Professor Taylor has an amazingly soothing voice. Listening to a subject like this would normally have my head spinning but she manages to convey so much while keeping you sane!
It's the rarest of scientists who can explain concepts of such complexity and breathtakingly wide scale, so clearly. With so gracious and humble a manner as to make a lay audience feel like she's addressing us as equals, not idiots. Even though she's casually on a first-name basis with "Stephen" and "Roger" (Hawking and Penrose). Marika Taylor must be a priceless lecturer and advisor. I just hope that her senior administration roles don't keep her out of the classroom.
Outstanding style of lecturing. Showing the big picture and then trying to work out how things work. Always empowering the viewer to be an active participant in the process of learning.
A thought I had just now looking at the gravity pull picture, which I, too, have seen plenty of times: If I imagine this picture in a three-dimensional context, to accommodate for our natural perception, it would seem intuitive, and I have always done this without thinking about it, that the gravitational pull would tense the grid around a mass. In your presentation I realized it's the opposite if it pertains to the change in space-time, as the canonical depiction presents! It would push the reference points outward, to make every vector more distant apart. Which would then mean that a black hole could not be represented in a three dimensional space-time graph. That means it stands singular, beside the original graph. Most mindblowing realization today about black holes and terminology.
It is exciting that the idea of a Black Hole is associated with a Quantum Computer. I think of a black hole as a storage device that captures and stores light (information). With Hawking radiation, this light can be released. Also, when the universe dies, all of this information is released in a burst of light. It would be interesting if we could one day construct technology to "read a Black Hole."
It's a great lecture. I believe that taking a step closer to what it means to be critical about what we know and questioning it each time, even when we think we know more, will be a path towards understanding. Even with hints given, we are likely to go through a process of repeatedly trying to assemble that new hint into the context of our great accomplishments.
When 2 particles become entangled either because they interact or are created as a pair, do they ever become unentangled? If so the number of separate entanglements in the universe is enormous. Equal to the number of particles in the universe multiplied by the average number of entanglements a single particle may experience in it time of existence. That is a big number.
yes, entangled particles can become unentangled - if they interact with other particles. but 2 entangled particles in a pure vacuum more or less never unentangle spontaneously .
What a plesant and calming voice, dr. Marika has ☆☆☆☆☆ Thats all what an intelligent man, wants to hear on a cold Rainy day ❤ Grtz from the netherlands Johny Geerts
Interesting similarities where you wouldn't have expected them! What about the Holographic Principle, this should also apply to this idea, if I understood it correctly?
Incredible lecture! My question would be, the information of the matter is preserved on the surface of the event horizon, does this information persist in an unchanging state indefinitely? Time doesn’t cause any fluctuations, because time is frozen or ceases to exist at the event horizon? Is it that time ceases to exist at the event horizon, or is time part of the data that is recorded? And if it is part of the data that is recorded, does the Black Hole therefore grow physically just as a result of spacetime entering it, even with no additional matter?
Imagine being that sort of Visionary in 1783 ! John Michell was lucky he wasn't beheaded for such Madness!! In fact, he was Light Years beyond those medieval Fools !!
TLDR: not what the title promises.... Spaghettification is the term used for things falling in a black hole. This theory abt qbits entangled with others inside the horizon is quite old,i took a course 5 years ago on quantum cryptography and this was one of the things i remember. Some information is coming out in evaporation, but not all. The Dyson sphere made me question the speaker's seriousness.
re 42:50 If she thought about the rate of time at all, she should have mentioned it here. Thus, the rate of time, close enough to the EH to separate a pair of virtual particles should be infinitesimal, meaning that despite virtual particles on earth might form trillions of times per CC of space, at the EH, they might only have formed several times since its formation around a tiny BH. BTW, the smaller the BH & its surface area, the greater the percentage of those few particles that could be separated permanently, such that there might be just as few Hawking particles around a big BH as a tiny one.
brain, an entangled system coordinating inputs and outputs, to discipline the system and environment for stasis. or energy conservation depending on the level of intent, proto intent, or disciplined intent.
I always thought it would be amazing to simulate a black hole in a quantum computer. The more we understand about black holes, the closer we get to a type 3 civilization.
Re 49:30 I think I understand why there is no 'singularity' of infinite density; because time is frozen at the EH. Particles do not move. The chair, computer, eyeball, etc that survive the approach thru the thermal & tidal stresses are not moving relative to us and their surroundings, and accumulate like archeological layers, fossilized in space-time. Perhaps you can figure the implications if not the maths.
I thought it was immensely thought provoking and brilliantly presented. None of the egotistical “jokes” offered by many presenters. At some point in the future it might be found that Marika has got some things wrong ….. so what that is cutting edge science for you.
I look at Startrek say Next Gen. Data, Tricorders, medical developments, some of the beam weapons, the computer structures all straightforward. The rest mostly impossible.
I realized that its hard to realize who is Bob. Bob is living in 9 dimensions but is fix in one place rather opposite to Alice who is doing the actions and motions. She is the one who plans and calculate and execute those plans/ideas/theories into the final output and product. Thus from start to a finished product Alice has to takes so many steps or actuating so many interconnecting switches in her circuitry that over time those parts/switches and circuitry wear out and causing defects and contaminations within her domain. It is that failure of one or two switches that become the beginning of the end of Alice. Alice is said to be an easy victim of the 2nd law of thermodynamics. Alice by herself is a computer system that can not sense or sees the defects and contamination on her switches and circuitry. To see her own skin she will need help from someone else outside of herself, that would be Bob. Bob in its basic form is a set of interconnecting sensors that sense and recognize what Alice forms and functions are. For example taste recognitions, touch recognitions, vision recognitions, smell recognitions, sound recognitions. These are Bob's domain, the domain of measurement. Believe it or not your mind can access both Alice and Bob domains in term of milliseconds. I'll be back
Re 58:50 Of course, a Dyson Sphere (only intended to be a thought experiment) would require many times the mass of any planetary system, and face insurmountable tidal, torsional, and rotational stresses (even if you could futilely make it football shaped to compensate for Coriolis effects).
Continue. Bob being a sensory feed back system first uses the eyes which gives him big field of view, big event horizon, and seeing more composite material in one shot. If consciousness is emerging this is it. Bob doesn't care about the detail of what Alice is made of. He just wanted to know what her final computation is. The final result is that the light is not working. Now Bob must look into more detail into Alice circuitry and makeup. Here a volt meter being use to find out where is the voltage drop is inside Alice circuitry. Finding a voltage drop inside an electrical circuit is the same thing as finding a high resistance inside a circuit. What causes this high resistance in a circuit? if you are an electrician you'll find out that the cause of high resistance was due to contamination on a circuit and or defects on the circuit. Contamination means an object from another place deposit on it a defect is a shape and size that is differ from the require design. Examples of contamination are rust, dust, dirt, and finger print Example of defects are the copper wire is too small or pinch or bent or not round and on concern the shape and of Alice circuitry make up. The point is contamination and defects are the stuffs that prevent the light from working correctly. These are gives from our eternal enemy the 2nd Law of thermodynamic. We must remove them in order to save Alice.
Yes, I agree....a very elementary, Sunday-driving (101) explanation of black holes..... I 've skipped to Black Holes and Quantum Theory....ok...I'm skipping ahead...not much more revelatory for me there...I'm not a scientist by nay stretch, just sort of Black Hole nut..! 48:00 on is about the state of my 'knowledge" of current blackhole research...
Someone had told me that in order to find out what an event horizon is you have to travel into the black hole. Then he pulled a recent picture of a real black hole. Then he point out where is the event horizon is, I told him that version of the story is true BUT.. The event horizons; actual event horizon vs apparent event horizon. Here we have observation and measurement as meaning the same thing. The primary tool of measurement is sensory perception plus the tool you are using to measure/observe. Ok the correct tool you going to use is a telescope that gives you good nice resolution in your field of view. But there are more smaller detail beneath that picture that you and your telescope can't see clearly. But let lock into the actual event horizon as being the place where you can see and the place where you can't see. Now this actual event horizon can be change to apparent event horizon if you change your tool/telescope to another one so that you can see into more detail. Now the fuzzy detail before become clear and its has its own new, actual event horizon. Sometime using your eyes to measure something is not the right tool to do so but you do it anyway because that what you got at that time or you was lazy to get a meter stick to measure it properly. This is where the event horizon shift here and there and you pay the price. What is that price that you pay after the correct measurement? You have to clean up all the garbage/mistakes that you made? What you wants isn't what you get.. YIELD TO THE MEASUREMENT. I'll be back
If a black hole is a giant hard disk, where does the information go after it fills to capacity? Or, in principle, does it not store information until it fills to capacity?
At about 23:00 there is the classic "Interstellar" image of the light around a black hole. Can you tell me or explain why the image is asymmetric. Between the 2 light disks (horizontal and vertical) there are 2 "fillets" of light on the top side, but none on the bottom. An explanation I have heard is that light passing behind the black hole is curved over the top and bottom of the black hole. Hence the vertical light disk. I think this image is still far from reality. Why is the top different from the bottom?
Today topic is the assembly of objects into Alice's world or Bob's world. A pencil can function as a switch or as a sensor. A pencil is a switch when you being Alice take actions to print your name on a piece of paper. But as you got halfway to completing your printed name, you being Bob senses the pencil's tip broke. Here the sensation through the pencil as the pencil brakes qualify the pencil as a sensor. Thus a pencil can be a switch or a sensor. A switch is being use by Alice to do her computational actions while a sensor is being use by Bob to do his sensing, measuring, and detecting. What about a blind person with his/her walking stick? Yes at one time the stick is a switch while at another time it is a sensor. How about a microscope? Yes a microscope can be uses as a switch to print a circuit board and it can also be uses as a sensor to inspect and measure circuit. Remember that in Alice's world she operates on interconnecting switches while in Bob's world he operates on interconnecting sensors. Instead of flipping a simple light switch Alice can take her computational actions to turn on a switch that run a whole car manufacturing complex that made out of billions of switches/steps to print out a car for example. But a long list of computational actions without Bob inspecting and measuring every parts is a bad gamble. We talking about no quality control what so ever. Just brute computer actions blindness. I'll be back
She keeps mentioning solar mass black holes (twice now) when the Chandrasekhar mass limit is 1.4 solar masses. So I’m getting tense in case she says it a third time now 😮
@@epajarjestys9981 that’s the most daft and inappropriate statement ever mentioned in science. Worse than saying Pi is 3. You have missed everything science stands for. Utter hogwash. Wrong in the wrongest of ways, was your astrophysics degree bought in Woolworths ?
I’ve heard of the information paradox with black holes, and I obviously need to watch some more tube videos on it (or break out some books and papers), but I don’t understand this whole “requirement” for the information to be conserved in the black hole. If I drag a powerful magnet over my unprotected hard drive, entropy rules and dishes my bits into unusable gibberish loosing all the information therein, and no one questions it. Why should we think that throwing my hard disk into a black hole should somehow mystically result in retention if my information but not so with the magnet? I’m obviously missing the point.
hardisk example - but still it's possible to recover that data....u can throw that hardrive into the sun and can still trace back the data if you can recover all the materials that is thrown in to the sun, the matter and fundamental particles that made that hardive still exist in the universe and some god-like species can reconstruct back that hard from those particles problem with blackhole is- it will just disintegrate your hard drive into nothingness (all that matter and fundamental particles which make that hardrive is gone forever) also watch this video - Can protons decay? Fermilab and google why electrons don't decay that will also clear some of your doubts
for instance.. if you throw a book into a fire, all of the atoms and stuff are converted by the fire into other stuff (carbon and gas etc), nothing is actually destroyed. if you ran it in reverse, the fire would appear to materialize a book. but a black hole seems to be a bit different
The way to translate this math of entanglements is to say that Bob and Alice is the same person or just one MIND with two versions of itself. Alice is the person/ACTOR inside the black hole while Bob is the person/OBSERVER that is outside the black. What Bob knows outside the black hole is what Alice knows inside the black hole. What ever happen should be SELF EVIDENCE. This is just one MIND being split into two places. This is the basic idea between black hole physic and worm hole physic. Alice is the actor or person doing the computer actions inside the black hole while Bob is the OBSERVER outside the black hole MEASURING Alice's computer actions. Observing and measuring means the same thing here, in biological terms these are SENSORY FEED BACK/SENSORY PERCEPTION systems. Alice's world is a computer world that uses interconnecting computer switches while Bob's world is a measuring world that uses interconnecting sensors. I'll be back.
At 21:36 there is a dot point saying "Jets are emitted from a black hole." I thought the whole point of a black hole is that NOTHING can be emitted from a black hole. So where are the jets really coming from?
The black hole has near infinite mass beyond the event horizon. So, since the mass is nearly infinite, I can't absorb anything additionally. Basically, nothing is absorbed but ends up in orbit instead. As the black hole evaporates, it loses gravity, and those orbitals have transcendent speeds, so they escape as some form of light.
At 41:00 we are introduced to Hawking radiation. Can I take it that the "jets" coming from black holes are in fact Hawking radiation which is being directed towards 2 poles?
No, the Hawking radiation would be around the event horizon dissipating the mass of the BH over trillions of years even in pitch blackness The jets coming from the poles is just interactions of all the mass trying to fall into the maelstrom, it can't fall in fast enough.
Black holes are ten-dimensional, obviously. Zero is the only number with a horizon through it so 0 and 10's geometric counterparts 0D (quantum) and 10D (cosmological) are the event horizon boundaries of this side of the mirror universe.
I can’t relate to the idea that information loss goes against the laws of quantum mechanics. Everytime entropy increases information is lost. Any process of diffusion; evaporation, sublimation looses information. Why do Black holes need to store information in the event horizon while it will be impossible to determine what where inside a water glass a dye was introduced once it had diffused uniformly? I am sure there is an answer. Smart enough to know I am not smart enough.
The spin of one particle is +1. The spin of the other is -1. It adds up to 0. This is one beam in two places, coded here, decoded there. Laminar shifted.
According to Marika Taylor quantum computer is black hole and according to Dr, Michio Kaku biological agents such as plants, animals, and human are quantum computer. Now this make us human qualify as a walking and talking black holes/quantum computer. No kidding I totally agree with this idea. So far most of the physicist are good at talking about black hole but the other competing structure to black hole is worm hole, they seem to be limited. In quantum physic there are wave function and follow by the collapse of the wave function/measurement. The physic of wave function is the physic of black hole but the physic of worm hole is the physic of measurement. What is in the wave function/black hole physic it is the actions/ specifically the actions of a computer (classical or quantum). I called the actions done by a computer a computer actions. I ll be back.
Now lets remind ourself that Bob and Alice is just one person or one mind being split into two versions of itself one is a black/Alice and one is the wormhole/Bob. Alice is doing the computational actions and Bob observes and measures Alice's actions. Alice world is stuck at the common 4d while Bob world is stuck at a higher dimensions of 9d. That's from having space folded to form a wormhole/two black hole. The issue with Alice's is that she is blind to the 2nd Law of Thermodynamic in every time she takes a computational actions she uses switches to do so. And those switches wear out over time given of byproducts such as heat, dust, and dirt. Those dust and dirt lingered there where it can contaminates and cause defects to some other computer switches in an automated production floor. When a switch is no longer working we said that one bit of information is lost to 2nd Law. So the more Alice's is computing the more information is lost. That means Steven Hawken is winning, Relativity is winning, inside the black hole. But if Bob able to observes/measures every actions that Alice makes live(at present state) those information is conserve by both recognition and storing in memory. Now to looks at every switch in detail inside a computer live is not easy. This is why we let Alice do her computational things for a while then we bring Bob in for measurement and inspection of the final product at that time. Ill be be.
I said APR bridge is wrong. It should be EPR bridge. It is the bridge that pinches the two black holes into a wormhole. What you understand by now is that black hole describe the internal working of the mind or what physicist called the wave function. When they said matter is a wave this what they mean. Everything they do and said has nothing to do with measurement here. Its all about idea, thought, thinking, computing, simulating, and automation. When they said matter is a particle what they mean is the external working of the mind or the physic of wormhole. This is about using you five senses as the main tool of measurement. Its about 5 types of recognition systems. Secondary measuring tools such as meters, sensors, microscope, and detectors can be add on to our 5 senses to gain resolution and precision. But note that those extra tooling by itself is not the one that do the measuring. In order for those extra tooling to do a measurement by itself you have to add a recognition board and program to it. For example a camera by itself can not be a measuring tool unless you add an image recognition to it. Another example your finger can work both ways as an internal and external tools. You can uses your finger to write or print letters in the sand, that is internal actions but it can also senses those actions or measures those actions live. Its is this fast switching between the internal mind and the external mind that make biological systems very powerful. This is fast live and in your face. This is the way we fight entropy.
Lets say using a volt meter you found a a high resistance or voltage drop in one of the leg/terminal of the light switch. You further look at the connection with your own eyes and find out that the connection has rust and corrosion. You figure out the cause of the room light not working is the fact that this corrosion prevent current from flowing from power to the light bulb. You then proceeded to fixes the matter by polishing out the rust and corrosion. The wire and the terminal in question is now nice and shining. You connect the terminal and again ask Alice to switch on the light while Bob look at the light bulb to see if there any light. The light switch is in the on position and Bob see the light. Alice by her own logic and computational world said the light should be on and Bob the observer outside Alice's world agrees that the light is 100% on. No more information lost and Dr, Leonard Susskind is winning. I'll be back
Lets look into how we make a computer chip and see how we can understand the APR bridge. A bridge only form during the measurement/observation process. Not the design or manufacturing process. So if there is a measurement or an inspection going on there must be a bridge or a wormhole. The external world that we see around us come out of that wormhole. The internal world start with the abstract idea and continue on as automation/simulation of that abstract idea to create or produce the finale product. Thus the internal world as describe by blackhole physic never create a bridge to the outside world in a matter that is outside the computer simulation. Here the final product is still in a computer simulation. The final product is said to exist in the external world if and only if someone looks at it live. Looking at the product live will allow us to differentiate the idea before ( in the mind of the creator} and the idea now. There is no amount of theories or simulations or computation or math or logic you can do to enter the outside world. The only ways you can bridge or enter the outside world is through your 5 senses. Also I haven see the 6 senses or 7 senses. Yes 5 senses equal 5 wormholes or 5 different type of measurements/observations.
There are people who job and career is doing TESTING. They are test engineers or test technicians. Test engineers are not part of the engineers department but part of the manufacturing department. They are on the floor working. So what is so important about TESTING? TESTING gives us the ability to selects the bad from the good products. The mind of a test engineer is always working in both Alice world and Bob world. In term of dimensions that is both in the 4D and 9D. Or we can say that the mind of a test engineer works in blackhole and wormhole physic. This is different than those engineer, designer, director, physicist, mathematician, and upper management where their minds are always stuck in the 4th dimensions of Alice world. In this blackhole physic information is always lost. Those minds that are in this category may think that everything is going great as plan but in reality they are building a bridge to nowhere. Really if you look at the structure of a blackhole it leads you right into the path of destruction at the end. Unlike a wormhole which has the EPR bridge the blackhole has none. So the idea here is that Alice and Bob must work together in order to ensure a good and reliable product.
Did anyone else feel that this presentation made perfect sense until she said “there’s a giant hard drive storing information as qubits”. Wait, what? She said the details of how that’s done is not important but I thought that was the whole point of the talk. Like every other discussion of quantum computing: “two entangled states plus quantum indeterminacy and then a miracle occurs.”. And then “error correction.” Maybe its just my low IQ that this seems like hand waving? How do you get one right answer to a calculation from that?. So it seems like the point of the talk which is that “Black Holes are Quantum Computers” is an assumption of the talk. To my lawyer-level intelligence, I heard no explanation for why we think that’s the case. If anyone knows where I could find that explanation please let me know. And what about the holographic theory … is it now a hologram created by a quantum computer?
How long does Alice takes to flip a light switch? Less than a second. How long does Bob takes to RECOGNIZES the light is on or off? Less than a second. Alice is doing the walking and talking but Bob is doing the listening and riding/guiding. Bob is listening is about Bob RECOGNITION to speech/sound. It's not about some kind of recording device and called it as a listing devise. I mean the device by itself can not listen unless its has a voice recognition board connected to it. Thus a voice recognition system qualify as a measuring system or a sensory perception system. A camera or a microscope that are connected to an image recognition board would qualify as a measuring system too. Some machine can record images but it couldn't recognizes those images. AI that is fixed to one location would qualify as a measuring system/Bob. AI that can walks and talks and recognize images would qualify as Alice and Bob together as one mind.
Bob, Measurement and its Resolution power. Your main tool of measurement is sensory perception. That is tasting, touching/feeling, smelling, hearing, and seeing. These are what Bob uses to collect/measure information given off by both Alice's computer actions and the 2nd Law of Thermodynamic. Bob uses interconnecting sensors to measure/confirm that what Alice is doing is true or not. Alice actions is confirm true if Bob manage to capture most if not all information send/reflected off Alice. Alice actions is false if Bob detects/measures very little information or no information at all coming from Alices computed actions. Hence information is lost. Alice is endanger of becoming an easy victim of the 2nd of thermodynamic. A quick fix of Alice's computer switches/circuit maybe need to fix the information lost. Now when someone ask you to go to measure something, what did you do? You going to take an action to do so. First and foremost is you primary tool of measurement which is your sensory perception. Second is what tool are you going to measure with? A ruler, a micrometer, a camera, a light microscope, an electron microscope, a electron tunneling microscope, or the LHC. Notice that all the tools of measurement are just add on sensors to your sensory perceptions to give you a better resolution. An electron microscope by itself does not do measure or know how to measure but if you add it with your one of your 5 senses then it become part of the measuring system. You want to add on the measuring tools above to get a better resolution/detail. This here is if you want more detail you will loose the bigger picture. Then why would you use/wear an electron microscope on your head just to read stop signs. The issue in physic is the same thing here. Where is the event horizon? Who can see what? If you what to see deeper into a black hole interior uses a more powerful microscope. And that will change your event horizon. I'll be back
The job of the physicist, the engineer, the inventor, the creator, and the upper manager is to produce big idea, big computation and simulation. This is not about making small table and chair. Thus the bigger the idea is the bigger the computational process, and the bigger and longer the black hole is. Also the actions /steps and wave function is long too. The idea behind space X star ship or making a car or making a computer chip are big. So how can we save those big ideas as it it goes from thought to manufacturing. The problem here is the 2nd Law of Th.Dy. is in the way. When idea clash with 2nd Law, the 2nd Law win. Its simple the big idea has too many switches, steps, and moving parts. Every action causes heat, friction, wear and tear. Thus at the end of the process or the end of the black hole we get nothing but dust and dirt. The idea/Alice is dead inside a black hole. In order to save the idea/Alice we need to build a bridge with the black hole called the measurement. So where and when we can build those bridge?
@@Uradumbxss Now now. Let's not exaggerate... There were only (_ONLY_ he says!) 166 "you know" s and 44 "kind of" s in the [automatically generated] transcript. But also 166 "um"s, making the average number of verbal fillers about 6 per minute - 1 every 10 seconds. (Somewhat surprisingly, the words "um you know" only appeared together 8 times, "you know um" 3 times, "kind of you know" 4 times, and "you know kind of' only once)! BTW - the phrase "black hole" only appeared 139 times, "quantum" 92 times, "computer" 31 times - with 16 of those being combined into the phrase "quantum computer". And um the you know word "Cubit" made 5 kind of guest appearances.
Qcomputing is a marketing thing, its going to be used for banking and cryptography, and maybe medicine. idk, seems more like a hype word to gain investors though as of now
People tried nuclear weapons and it didn't come close to making anything as dense as it needs to be to bend spacetime into itself. Many orders of magnitude far away from achieving such a weird feat.
Cause the goal, was energy release and not creating a black hole or bending spacetime 🙄 And how do you know there wasnt any influence on space time. If we are barely able to measure supermassive blackholes merging 80years later. We do need way more sensible instruments to measure the same effect of two heavy particles merging.
I'm still amazed by how they managed to capture this gravitational blip that probably happened billions light years away, it's like they recorded a fart of a mosquito from another galaxy.
Today is the day that we are going to get down on explaining the everyday blackhole wormhole physic . I will use three examples to explain how this all work. Here is the first example: Lets say that you being Alice take a computer actions to turn on a light in a dark room. And you being Bob looks at the light bulb on the celling to see if there is any light at all. Now this is what I call a complete quantum system in which actions and measurement come in one set. Ok continue. Alice flip the light on but Bob did not see see any light coming on. So there is a big disagreement here between Alice and Bob perspectives. Alice by her own logic, deductive reasoning said that there should be light as the final product of her computation. When the light does not works we called this missing information. Where the theory doesn't match the measurement/observation. So how do you fix this missing information? You (being Bob) bring out your volts meter in addition to your eyes. This volts meter is to find out where is the voltage drop inside Alice computer circuitry. I'll be back
Is it possible that because there is a Plank length and a Plank time it is possible that the probabilities of quantum states is simply that we have not been able to measure accurately at the scale of Plank time and Plank length.? Where we can the probabilities will reduce to quantums.
Professor Taylor has an amazingly soothing voice.
Listening to a subject like this would normally have my head spinning but she manages to convey so much while keeping you sane!
It's the rarest of scientists who can explain concepts of such complexity and breathtakingly wide scale, so clearly. With so gracious and humble a manner as to make a lay audience feel like she's addressing us as equals, not idiots.

I just hope that her senior administration roles don't keep her out of the classroom.
All that glitters is not gold and also having a personal experience most of the times makes the magic disperse into thin air.
I still remember Marika as one of my favourite professors at the UvA. She is still excellent in explaining difficult subjects

Fascinating. I've encountered these concepts elsewhere but Marika has explained this so well.
A thought I had just now looking at the gravity pull picture, which I, too, have seen plenty of times:
If I imagine this picture in a three-dimensional context, to accommodate for our natural perception, it would seem intuitive, and I have always done this without thinking about it, that the gravitational pull would tense the grid around a mass. In your presentation I realized it's the opposite if it pertains to the change in space-time, as the canonical depiction presents! It would push the reference points outward, to make every vector more distant apart. Which would then mean that a black hole could not be represented in a three dimensional space-time graph. That means it stands singular, beside the original graph. Most mindblowing realization today about black holes and terminology.

When 2 particles become entangled either because they interact or are created as a pair, do they ever become unentangled?
If so the number of separate entanglements in the universe is enormous. Equal to the number of particles in the universe multiplied by the average number of entanglements a single particle may experience in it time of existence. That is a big number.
yes, entangled particles can become unentangled - if they interact with other particles. but 2 entangled particles in a pure vacuum more or less never unentangle spontaneously .

Further implications are eagerly awaited!!
Wonderful and inspiring lecture!
Interesting similarities where you wouldn't have expected them! What about the Holographic Principle, this should also apply to this idea, if I understood it correctly?
Yes
Brilliant lecture, thank you 🙏
Incredible lecture!
My question would be, the information of the matter is preserved on the surface of the event horizon, does this information persist in an unchanging state indefinitely? Time doesn’t cause any fluctuations, because time is frozen or ceases to exist at the event horizon? Is it that time ceases to exist at the event horizon, or is time part of the data that is recorded? And if it is part of the data that is recorded, does the Black Hole therefore grow physically just as a result of spacetime entering it, even with no additional matter?
An excellent talk. 👏
On the hole, it was a good lecture.

I thought it was a bit fuzzy.
Let's hope there's another on the horizon 🙏

Wow I learned something new today.
There are five Happy Gravities and they live at 1011 West Olive Street Oxnard California.
Super duper interesting.
One of the best lectures RI has put out.
TLDR: not what the title promises....
Spaghettification is the term used for things falling in a black hole.
This theory abt qbits entangled with others inside the horizon is quite old,i took a course 5 years ago on quantum cryptography and this was one of the things i remember.
Some information is coming out in evaporation, but not all.
The Dyson sphere made me question the speaker's seriousness.
Hi you sound knowledgeable on black holes. What's your opinion about them? Would the latest research results on them be the holographic principle?
AWESOME! 👌
Dr.Marika,
☯️ Converging once we surfing the negative Antiparticle fluctuation the black hole is kind of cosmos balancer
re 42:50 If she thought about the rate of time at all, she should have mentioned it here. Thus, the rate of time, close enough to the EH to separate a pair of virtual particles should be infinitesimal, meaning that despite virtual particles on earth might form trillions of times per CC of space, at the EH, they might only have formed several times since its formation around a tiny BH.
BTW, the smaller the BH & its surface area, the greater the percentage of those few particles that could be separated permanently, such that there might be just as few Hawking particles around a big BH as a tiny one.

I think your explaining information.
brain, an entangled system coordinating inputs and outputs, to discipline the system and environment for stasis. or energy conservation depending on the level of intent, proto intent, or disciplined intent.
What a great lecture
I always thought it would be amazing to simulate a black hole in a quantum computer. The more we understand about black holes, the closer we get to a type 3 civilization.
Lol. How about type 1 first
Re 49:30 I think I understand why there is no 'singularity' of infinite density; because time is frozen at the EH. Particles do not move. The chair, computer, eyeball, etc that survive the approach thru the thermal & tidal stresses are not moving relative to us and their surroundings, and accumulate like archeological layers, fossilized in space-time. Perhaps you can figure the implications if not the maths.
Very interesting
Good presentation. However, instead of Hawking, Bekenstein would have been more apt.
I looked for a Black Hole Quantum computer on Amazon but can’t find it. Anyone?
I thought it was immensely thought provoking and brilliantly presented. None of the egotistical “jokes” offered by many presenters. At some point in the future it might be found that Marika has got some things wrong ….. so what that is cutting edge science for you.
I look at Startrek say Next Gen. Data, Tricorders, medical developments, some of the beam weapons, the computer structures all straightforward. The rest mostly impossible.
I still don't understand why scientists think information cannot be lost. They haven't seen my boss' handwriting.. 😂
Ah,, but does said boss make sense even when talking?
I realized that its hard to realize who is Bob. Bob is living in 9 dimensions but is fix in one place rather opposite to Alice who is doing the actions and motions. She is the one who plans and calculate and execute those plans/ideas/theories into the final output and product. Thus from start to a finished product Alice has to takes so many steps or actuating so many interconnecting switches in her circuitry that over time those parts/switches and circuitry wear out and causing defects and contaminations within her domain. It is that failure of one or two switches that become the beginning of the end of Alice. Alice is said to be an easy victim of the 2nd law of thermodynamics. Alice by herself is a computer system that can not sense or sees the defects and contamination on her switches and circuitry. To see her own skin she will need help from someone else outside of herself, that would be Bob. Bob in its basic form is a set of interconnecting sensors that sense and recognize what Alice forms and functions are. For example taste recognitions, touch recognitions, vision recognitions, smell recognitions, sound recognitions. These are Bob's domain, the domain of measurement. Believe it or not your mind can access both Alice and Bob domains in term of milliseconds.

Re 58:50 Of course, a Dyson Sphere (only intended to be a thought experiment) would require many times the mass of any planetary system, and face insurmountable tidal, torsional, and rotational stresses (even if you could futilely make it football shaped to compensate for Coriolis effects).
not at all, you could easily convert a single planet into a dyson sphere, or a dyson swarm. all you need is a shell, not an entire solid sphere
I think my five Happy Gravities are a quantum computer.
Continue. Bob being a sensory feed back system first uses the eyes which gives him big field of view, big event horizon, and seeing more composite material in one shot. If consciousness is emerging this is it. Bob doesn't care about the detail of what Alice is made of. He just wanted to know what her final computation is. The final result is that the light is not working. Now Bob must look into more detail into Alice circuitry and makeup. Here a volt meter being use to find out where is the voltage drop is inside Alice circuitry. Finding a voltage drop inside an electrical circuit is the same thing as finding a high resistance inside a circuit. What causes this high resistance in a circuit? if you are an electrician you'll find out that the cause of high resistance was due to contamination on a circuit and or defects on the circuit. Contamination means an object from another place deposit on it a defect is a shape and size that is differ from the require design. Examples of contamination are rust, dust, dirt, and finger print Example of defects are the copper wire is too small or pinch or bent or not round and on concern the shape and of Alice circuitry make up. The point is contamination and defects are the stuffs that prevent the light from working correctly. These are gives from our eternal enemy the 2nd Law of thermodynamic. We must remove them in order to save Alice.
30 mins in. Light can't escape blackholes and interstellar was good. Hope it gets better.
Yes, I agree....a very elementary, Sunday-driving (101) explanation of black holes..... I 've skipped to Black Holes and Quantum Theory....ok...I'm skipping ahead...not much more revelatory for me there...I'm not a scientist by nay stretch, just sort of Black Hole nut..! 48:00 on is about the state of my 'knowledge" of current blackhole research...
This is aimed at the general public audience including very young people. It is totally ok to not go *full nerd mode* here.
@@W00PIE the title says quantum computing, but there is not much quantum computing in this lecture, mostly basics on black holes.
Someone had told me that in order to find out what an event horizon is you have to travel into the black hole. Then he pulled a recent picture of a real black hole. Then he point out where is the event horizon is, I told him that version of the story is true BUT..
The event horizons; actual event horizon vs apparent event horizon. Here we have observation and measurement as meaning the same thing. The primary tool of measurement is sensory perception plus the tool you are using to measure/observe. Ok the correct tool you going to use is a telescope that gives you good nice resolution in your field of view. But there are more smaller detail beneath that picture that you and your telescope can't see clearly. But let lock into the actual event horizon as being the place where you can see and the place where you can't see. Now this actual event horizon can be change to apparent event horizon if you change your tool/telescope to another one so that you can see into more detail. Now the fuzzy detail before become clear and its has its own new, actual event horizon.
Sometime using your eyes to measure something is not the right tool to do so but you do it anyway because that what you got at that time or you was lazy to get a meter stick to measure it properly. This is where the event horizon shift here and there and you pay the price. What is that price that you pay after the correct measurement? You have to clean up all the garbage/mistakes that you made? What you wants isn't what you get.. YIELD TO THE MEASUREMENT.

If a black hole is a giant hard disk, where does the information go after it fills to capacity? Or, in principle, does it not store information until it fills to capacity?
2x speed works well for this one
are 2 entragled particles style entragled if we put one in a black hole?
Good question.
Well since information can leave a black hole through hawking radiation perhaps yes. That’s just an uninformed guess.
Yes, and there's no problem with that as entanglement does not transmit information from one place to another.
At about 23:00 there is the classic "Interstellar" image of the light around a black hole. Can you tell me or explain why the image is asymmetric. Between the 2 light disks (horizontal and vertical) there are 2 "fillets" of light on the top side, but none on the bottom.
An explanation I have heard is that light passing behind the black hole is curved over the top and bottom of the black hole. Hence the vertical light disk. I think this image is still far from reality. Why is the top different from the bottom?
i think the rendering is computed with a virtual camera that is slightly "north". so we are not seeing it edge on. we are seeing it slight top down.
What he said, plus spin and the direction of the accretion leads to Doppler beaming giving a left right asymmetry

Amazing talk but gosh it drives me nuts when people keep making the smacking noise on mic
Today topic is the assembly of objects into Alice's world or Bob's world. A pencil can function as a switch or as a sensor. A pencil is a switch when you being Alice take actions to print your name on a piece of paper. But as you got halfway to completing your printed name, you being Bob senses the pencil's tip broke. Here the sensation through the pencil as the pencil brakes qualify the pencil as a sensor. Thus a pencil can be a switch or a sensor. A switch is being use by Alice to do her computational actions while a sensor is being use by Bob to do his sensing, measuring, and detecting. What about a blind person with his/her walking stick? Yes at one time the stick is a switch while at another time it is a sensor. How about a microscope? Yes a microscope can be uses as a switch to print a circuit board and it can also be uses as a sensor to inspect and measure circuit. Remember that in Alice's world she operates on interconnecting switches while in Bob's world he operates on interconnecting sensors. Instead of flipping a simple light switch Alice can take her computational actions to turn on a switch that run a whole car manufacturing complex that made out of billions of switches/steps to print out a car for example. But a long list of computational actions without Bob inspecting and measuring every parts is a bad gamble. We talking about no quality control what so ever. Just brute computer actions blindness.

Super symmetrical super symmetry.
She keeps mentioning solar mass black holes (twice now) when the Chandrasekhar mass limit is 1.4 solar masses. So I’m getting tense in case she says it a third time now 😮
1.4 solar masses is roundabout 1 solar mass.
She's talking about order of magnitude here. Precise value is not relevant.
@@epajarjestys9981 that’s the most daft and inappropriate statement ever mentioned in science. Worse than saying Pi is 3. You have missed everything science stands for. Utter hogwash. Wrong in the wrongest of ways, was your astrophysics degree bought in Woolworths ?
I’ve heard of the information paradox with black holes, and I obviously need to watch some more tube videos on it (or break out some books and papers), but I don’t understand this whole “requirement” for the information to be conserved in the black hole. If I drag a powerful magnet over my unprotected hard drive, entropy rules and dishes my bits into unusable gibberish loosing all the information therein, and no one questions it. Why should we think that throwing my hard disk into a black hole should somehow mystically result in retention if my information but not so with the magnet? I’m obviously missing the point.
hardisk example - but still it's possible to recover that data....u can throw that hardrive into the sun and can still trace back the data if you can recover all the materials that is thrown in to the sun,
the matter and fundamental particles that made that hardive still exist in the universe and some god-like species can reconstruct back that hard from those particles
problem with blackhole is- it will just disintegrate your hard drive into nothingness (all that matter and fundamental particles which make that hardrive is gone forever)
also watch this video -
Can protons decay?
Fermilab
and google why electrons don't decay
that will also clear some of your doubts
for instance.. if you throw a book into a fire, all of the atoms and stuff are converted by the fire into other stuff (carbon and gas etc), nothing is actually destroyed. if you ran it in reverse, the fire would appear to materialize a book. but a black hole seems to be a bit different
The way to translate this math of entanglements is to say that Bob and Alice is the same person or just one MIND with two versions of itself. Alice is the person/ACTOR inside the black hole while Bob is the person/OBSERVER that is outside the black. What Bob knows outside the black hole is what Alice knows inside the black hole. What ever happen should be SELF EVIDENCE. This is just one MIND being split into two places. This is the basic idea between black hole physic and worm hole physic. Alice is the actor or person doing the computer actions inside the black hole while Bob is the OBSERVER outside the black hole MEASURING Alice's computer actions. Observing and measuring means the same thing here, in biological terms these are SENSORY FEED BACK/SENSORY PERCEPTION systems. Alice's world is a computer world that uses interconnecting computer switches while Bob's world is a measuring world that uses interconnecting sensors.
I'll be back.
At 21:36 there is a dot point saying "Jets are emitted from a black hole." I thought the whole point of a black hole is that NOTHING can be emitted from a black hole. So where are the jets really coming from?
the jets are coming from gas and plasma near the black hole
The black hole has near infinite mass beyond the event horizon. So, since the mass is nearly infinite, I can't absorb anything additionally. Basically, nothing is absorbed but ends up in orbit instead. As the black hole evaporates, it loses gravity, and those orbitals have transcendent speeds, so they escape as some form of light.
At 41:00 we are introduced to Hawking radiation. Can I take it that the "jets" coming from black holes are in fact Hawking radiation which is being directed towards 2 poles?
No, the Hawking radiation would be around the event horizon dissipating the mass of the BH over trillions of years even in pitch blackness
The jets coming from the poles is just interactions of all the mass trying to fall into the maelstrom, it can't fall in fast enough.
so, strictly, the jets don't come from the BH, they are external matter which is redirected by the strong fields near the BH.@@johnjakson444
Also blackhole are really cold. Way below the cmb …the temp is such that the wavelength peaks around the diameter.
When do I receive my Nobel Soul prize?
Black holes are ten-dimensional, obviously.
Zero is the only number with a horizon through it so 0 and 10's geometric counterparts 0D (quantum) and 10D (cosmological) are the event horizon boundaries of this side of the mirror universe.
I can’t relate to the idea that information loss goes against the laws of quantum mechanics. Everytime entropy increases information is lost. Any process of diffusion; evaporation, sublimation looses information. Why do Black holes need to store information in the event horizon while it will be impossible to determine what where inside a water glass a dye was introduced once it had diffused uniformly? I am sure there is an answer. Smart enough to know I am not smart enough.
The spin of one particle is +1. The spin of the other is -1. It adds up to 0.
This is one beam in two places, coded here, decoded there.
Laminar shifted.
information isnt actually lost , its just converted into heat under entropy , and spread out.
According to Marika Taylor quantum computer is black hole and according to Dr, Michio Kaku biological agents such as plants, animals, and human are quantum computer. Now this make us human qualify as a walking and talking black holes/quantum computer. No kidding I totally agree with this idea. So far most of the physicist are good at talking about black hole but the other competing structure to black hole is worm hole, they seem to be limited. In quantum physic there are wave function and follow by the collapse of the wave function/measurement. The physic of wave function is the physic of black hole but the physic of worm hole is the physic of measurement. What is in the wave function/black hole physic it is the actions/ specifically the actions of a computer (classical or quantum). I called the actions done by a computer a computer actions.
I ll be back.
Marika, I love how this research is unfolding. I wish I had met a woman as smart as you when I was young.
I thought it was going to tell us a concept for using black holes AS Quantum computers.............
This is gonna be good!
Now lets remind ourself that Bob and Alice is just one person or one mind being split into two versions of itself one is a black/Alice and one is the wormhole/Bob. Alice is doing the computational actions and Bob observes and measures Alice's actions. Alice world is stuck at the common 4d while Bob world is stuck at a higher dimensions of 9d. That's from having space folded to form a wormhole/two black hole. The issue with Alice's is that she is blind to the 2nd Law of Thermodynamic in every time she takes a computational actions she uses switches to do so. And those switches wear out over time given of byproducts such as heat, dust, and dirt. Those dust and dirt lingered there where it can contaminates and cause defects to some other computer switches in an automated production floor. When a switch is no longer working we said that one bit of information is lost to 2nd Law. So the more Alice's is computing the more information is lost. That means Steven Hawken is winning, Relativity is winning, inside the black hole. But if Bob able to observes/measures every actions that Alice makes live(at present state) those information is conserve by both recognition and storing in memory. Now to looks at every switch in detail inside a computer live is not easy. This is why we let Alice do her computational things for a while then we bring Bob in for measurement and inspection of the final product at that time.
Ill be be.
I said APR bridge is wrong. It should be EPR bridge. It is the bridge that pinches the two black holes into a wormhole. What you understand by now is that black hole describe the internal working of the mind or what physicist called the wave function. When they said matter is a wave this what they mean. Everything they do and said has nothing to do with measurement here. Its all about idea, thought, thinking, computing, simulating, and automation. When they said matter is a particle what they mean is the external working of the mind or the physic of wormhole. This is about using you five senses as the main tool of measurement. Its about 5 types of recognition systems. Secondary measuring tools such as meters, sensors, microscope, and detectors can be add on to our 5 senses to gain resolution and precision. But note that those extra tooling by itself is not the one that do the measuring. In order for those extra tooling to do a measurement by itself you have to add a recognition board and program to it. For example a camera by itself can not be a measuring tool unless you add an image recognition to it. Another example your finger can work both ways as an internal and external tools. You can uses your finger to write or print letters in the sand, that is internal actions but it can also senses those actions or measures those actions live. Its is this fast switching between the internal mind and the external mind that make biological systems very powerful. This is fast live and in your face. This is the way we fight entropy.
Could the Universe and everything in it be a Mandelbrot Fractal Zoom.?
Guess you didnt make it to the explanation at
34:15 - 37:50
Lets say using a volt meter you found a a high resistance or voltage drop in one of the leg/terminal of the light switch. You further look at the connection with your own eyes and find out that the connection has rust and corrosion. You figure out the cause of the room light not working is the fact that this corrosion prevent current from flowing from power to the light bulb. You then proceeded to fixes the matter by polishing out the rust and corrosion. The wire and the terminal in question is now nice and shining. You connect the terminal and again ask Alice to switch on the light while Bob look at the light bulb to see if there any light. The light switch is in the on position and Bob see the light. Alice by her own logic and computational world said the light should be on and Bob the observer outside Alice's world agrees that the light is 100% on. No more information lost and Dr, Leonard Susskind is winning.
I'll be back
What benefit is quantum ECC over regular ECC? It seems like quantum ECC is not stateless which makes it worse.
Lets look into how we make a computer chip and see how we can understand the APR bridge. A bridge only form during the measurement/observation process. Not the design or manufacturing process. So if there is a measurement or an inspection going on there must be a bridge or a wormhole. The external world that we see around us come out of that wormhole. The internal world start with the abstract idea and continue on as automation/simulation of that abstract idea to create or produce the finale product. Thus the internal world as describe by blackhole physic never create a bridge to the outside world in a matter that is outside the computer simulation. Here the final product is still in a computer simulation. The final product is said to exist in the external world if and only if someone looks at it live. Looking at the product live will allow us to differentiate the idea before ( in the mind of the creator} and the idea now. There is no amount of theories or simulations or computation or math or logic you can do to enter the outside world. The only ways you can bridge or enter the outside world is through your 5 senses. Also I haven see the 6 senses or 7 senses. Yes 5 senses equal 5 wormholes or 5 different type of measurements/observations.
We can only hope that achieving a Type 3 civilization on the Kardashev Scale will drop the price of Apple's memory storage options?💻
There are people who job and career is doing TESTING. They are test engineers or test technicians. Test engineers are not part of the engineers department but part of the manufacturing department. They are on the floor working. So what is so important about TESTING? TESTING gives us the ability to selects the bad from the good products. The mind of a test engineer is always working in both Alice world and Bob world. In term of dimensions that is both in the 4D and 9D. Or we can say that the mind of a test engineer works in blackhole and wormhole physic. This is different than those engineer, designer, director, physicist, mathematician, and upper management where their minds are always stuck in the 4th dimensions of Alice world. In this blackhole physic information is always lost. Those minds that are in this category may think that everything is going great as plan but in reality they are building a bridge to nowhere. Really if you look at the structure of a blackhole it leads you right into the path of destruction at the end. Unlike a wormhole which has the EPR bridge the blackhole has none. So the idea here is that Alice and Bob must work together in order to ensure a good and reliable product.
"Slogan"? "Escape SPEED"? I'm out.
Blackholes are the father mother to quantum computers , spices on earth on every planet work like wireless devices
If a black hole has a exhaust of any kind, means it has a limit or filters the matter it cannot influence from its existence.
Did anyone else feel that this presentation made perfect sense until she said “there’s a giant hard drive storing information as qubits”. Wait, what? She said the details of how that’s done is not important but I thought that was the whole point of the talk. Like every other discussion of quantum computing: “two entangled states plus quantum indeterminacy and then a miracle occurs.”. And then “error correction.” Maybe its just my low IQ that this seems like hand waving? How do you get one right answer to a calculation from that?. So it seems like the point of the talk which is that “Black Holes are Quantum Computers” is an assumption of the talk. To my lawyer-level intelligence, I heard no explanation for why we think that’s the case. If anyone knows where I could find that explanation please let me know.
And what about the holographic theory … is it now a hologram created by a quantum computer?
How long does Alice takes to flip a light switch? Less than a second. How long does Bob takes to RECOGNIZES the light is on or off? Less than a second. Alice is doing the walking and talking but Bob is doing the listening and riding/guiding. Bob is listening is about Bob RECOGNITION to speech/sound. It's not about some kind of recording device and called it as a listing devise. I mean the device by itself can not listen unless its has a voice recognition board connected to it. Thus a voice recognition system qualify as a measuring system or a sensory perception system. A camera or a microscope that are connected to an image recognition board would qualify as a measuring system too. Some machine can record images but it couldn't recognizes those images. AI that is fixed to one location would qualify as a measuring system/Bob. AI that can walks and talks and recognize images would qualify as Alice and Bob together as one mind.
Bob, Measurement and its Resolution power. Your main tool of measurement is sensory perception. That is tasting, touching/feeling, smelling, hearing, and seeing. These are what Bob uses to collect/measure information given off by both Alice's computer actions and the 2nd Law of Thermodynamic. Bob uses interconnecting sensors to measure/confirm that what Alice is doing is true or not. Alice actions is confirm true if Bob manage to capture most if not all information send/reflected off Alice. Alice actions is false if Bob detects/measures very little information or no information at all coming from Alices computed actions. Hence information is lost. Alice is endanger of becoming an easy victim of the 2nd of thermodynamic. A quick fix of Alice's computer switches/circuit maybe need to fix the information lost. Now when someone ask you to go to measure something, what did you do? You going to take an action to do so. First and foremost is you primary tool of measurement which is your sensory perception. Second is what tool are you going to measure with? A ruler, a micrometer, a camera, a light microscope, an electron microscope, a electron tunneling microscope, or the LHC. Notice that all the tools of measurement are just add on sensors to your sensory perceptions to give you a better resolution. An electron microscope by itself does not do measure or know how to measure but if you add it with your one of your 5 senses then it become part of the measuring system. You want to add on the measuring tools above to get a better resolution/detail. This here is if you want more detail you will loose the bigger picture. Then why would you use/wear an electron microscope on your head just to read stop signs. The issue in physic is the same thing here. Where is the event horizon? Who can see what? If you what to see deeper into a black hole interior uses a more powerful microscope. And that will change your event horizon.

How can jet come out of a black hole if nothing can come out of a black hole?
Aren't Black holes dead bed or grave yards of dead Stars?
The job of the physicist, the engineer, the inventor, the creator, and the upper manager is to produce big idea, big computation and simulation. This is not about making small table and chair. Thus the bigger the idea is the bigger the computational process, and the bigger and longer the black hole is. Also the actions /steps and wave function is long too. The idea behind space X star ship or making a car or making a computer chip are big. So how can we save those big ideas as it it goes from thought to manufacturing. The problem here is the 2nd Law of Th.Dy. is in the way. When idea clash with 2nd Law, the 2nd Law win. Its simple the big idea has too many switches, steps, and moving parts. Every action causes heat, friction, wear and tear. Thus at the end of the process or the end of the black hole we get nothing but dust and dirt. The idea/Alice is dead inside a black hole. In order to save the idea/Alice we need to build a bridge with the black hole called the measurement. So where and when we can build those bridge?
How jets can be emitted from the black hole when nothing can escape fom the black hole?
The jets are being emitted from the accretion disk that surrounds the black hole. Some of the matter falls in and some gets ejected.
Remarcable lection!

Yes, but not really. ;-)

Great 49 minutes lecture about black holes. Quantum computing? Just a footnote. Too bad.
Qcomputing is a marketing thing, its going to be used for banking and cryptography, and maybe medicine. idk, seems more like a hype word to gain investors though as of now
We don't know how information is stored and distributed by a black hole.
I know maam
People tried nuclear weapons and it didn't come close to making anything as dense as it needs to be to bend spacetime into itself. Many orders of magnitude far away from achieving such a weird feat.
Cause the goal, was energy release and not creating a black hole or bending spacetime 🙄
And how do you know there wasnt any influence on space time. If we are barely able to measure supermassive blackholes merging 80years later. We do need way more sensible instruments to measure the same effect of two heavy particles merging.
I'm still amazed by how they managed to capture this gravitational blip that probably happened billions light years away, it's like they recorded a fart of a mosquito from another galaxy.
Why was the astronaut non binary? 50:32 Was that a qubit joke? Maybe a bit too meta.
Today is the day that we are going to get down on explaining the everyday blackhole wormhole physic . I will use three examples to explain how this all work. Here is the first example:
Lets say that you being Alice take a computer actions to turn on a light in a dark room. And you being Bob looks at the light bulb on the celling to see if there is any light at all. Now this is what I call a complete quantum system in which actions and measurement come in one set. Ok continue. Alice flip the light on but Bob did not see see any light coming on. So there is a big disagreement here between Alice and Bob perspectives. Alice by her own logic, deductive reasoning said that there should be light as the final product of her computation. When the light does not works we called this missing information. Where the theory doesn't match the measurement/observation. So how do you fix this missing information? You (being Bob) bring out your volts meter in addition to your eyes. This volts meter is to find out where is the voltage drop inside Alice computer circuitry.

She killed it!
Hope quantum computers can fix bad audio hum in the future.....jeeeez
Nice!
