This is surely the best introduction to the holographic principle, I bet even on undergrad and post-grad level. It is concise, compact yet complete and thorough. Gives a very intutive and even rigorous enough approach to get the key points. Even if you don't understand deeply all the background there are enough tips to quickly follow and quench doubts. Prof. Bousso is really talented and deserve lots of credit.

Some "effective" academics are great because thaey are effective abstract theorists ... Others are great (academically) because they are great communicators. Raphael? ... You are clearly both, and very charismatic and engaging, "to boot". I love the way you managed the scope of this lecture ... I am truly entriched ! = Thank You, Kind Sir =

The universe is eventful. A fundamental primordial building block of our universe is a four dimensional Plank sphere called the primordial Plank Boson. Its 4D volume is an order of 10 to the power of minus 139 meter to the power of 4. This primordial Plank Boson consists of our whole universe and the universe consists of a huge number, of , about 10 to the power of 243 primordial Plank Bosons. Therefore, our universe is a Hologram. Dr. V. Keishna

The most informative and enlightening public access introduction to the holographic principle I've been able to find. If only documentaries on the so called learning stations would air material with this much substance. Thankyou!

Thank you for uploading. I've been looking for a more in depth while still layman's explanation of the holographic principle. Fascinating.

This man is an amazing "teacher". Very informative!

Great vid! Bousso is totally taken by the task to deliver a knowledge undoubtedly linked to some near future breakthrough. I swear I can feel his heart beating wildly!

(46:20) "...Somehow the world is not as local as we might thought it was!" We started to perceive that the world was not that local since Einstein-Rosen-Poldosky in the 30's I think... BUT THIS NEW PERSPECTIVE IS REALLY BEAUTIFUL!! UAU! UAU!! UAU!!!

The mathematical physicist Eugene Wigner - developed the concept of symmetry for quantum field theory - remind us that "philosophy is the misuse of a terminology which was invented just for this purpose" and that "mathematics is the science of skillful operations with concepts and rules invented for this purpose. The principal emphasis is on the invention of concepts". The Holographic Principle is one of such brainstorming concepts. The idea of a mental parallax seems to be very rewarding...

Maybe I could not comprehend so far is why a space of information within the plank length cannot be aware of it's surroundings? Speed, duration, destination, purpose (wow?)

Very interesting ! Thanks for posting.

The ‘multiverses’ or extra dimensions can be explained within our 3D space by using the holographic principle in the form of positive and negative charge. Photon energy forms the movement of charge with positive and negative charge forming a two dimensional boundary condition. We have the holographic principle at work with the info of 3D space on a two dimensional surface. This geometry is formed by the two dimensional surface of the spherical harmonics. With the inner concaved surface representing negative charge and the outer convex surface forming positive charge. This forms a two dimensional boundary condition with the future unfolding photon by photon with the movement of positive and negative charge and continuous flow of electromagnetic fields.

Very fascinating stuff! The last 10 to 15 minutes were a bit over my head so i ll prolly have to watch it a few more times but this relationschip between information content and surface area explained by using black holes was very well done! Thx!

Thanks for the explanation.

A few years ago, only people who knew stuff could communicate it. Now, with powerpoint, anyone can communicate anything, even knowing nothing about it! Raphael Bousos simply did not need powerpoint to transmit his message to the audience. Great!

It took 25 years for me to understand the beauty of math. Thanks man.

At the end of his talk Busso shortly refers to his null-like "Covariant Entropy Bound" (2002) which fits finite entropy theories like String Theory, Quantum Gravity and the Holographic Principle.It gives deep insight into the working of the HP.

the last thought-experiment he mentioned, the maximum amount of information which can be sampled by light rays during gravitational collapse, just before a singularity is reached, is blindingly wonderful. there's no a priori reason all these different lines of reasoning should end up all pointing towards "holography". yet they do. seems like some deep principle is at work here...

@hipstarchild Very interesting. Do you have any information you want to share to back it up? Funny as I was watching the video I started having a strong sense that we were already inside the black hole. Recursive embedded universes? Very interesting.

1. David Sereda invented the Galaxy Clock to show us that light=mass=gravity=electromagnetism, and by altering the frequency of light, …things CAN move faster than the speed of light. (I hope you can check out Mr. Sereda’s video presentation of this ultraviolet spectrum phenomenon - that of objects moving faster than light by virtue of the fact that they are vibrating faster than the frequency of visible light - and which can escape gravity / mass / electromagnetic fields with ease!)

2. The Galaxy Clock evidences an “ultraviolet” reality of light information (aka, gravity / mass / electromagnetism) at the center of black holes wherein --- the hole appears black because we are attempting to view it from our human reference point of Visible Light Reality. But, as the light/gravity/mass/time sped up toward the center of the hole - it didn’t become trapped by gravity, it simply changed frequency and appears black to our eyesight and perception. Please check it out.

No need to apologize I'm a physicist with training in astronomy, you could say this is my thing. I'll check out the video you mention, thanks.

Thank you for your excellent presentation on the holographic principle~ my husband, dr kitty and i are fascinated by black holes, string theory(ies) etc.. I'm trying to explain these theories to my family in NY:) your video is perfect~!

13:00 Fields imply infinite information 19:00 by E = mc^2, energy in vol. restricted by gravity / singularity potential ? BUT clearly Gen. Rel. is not correct, in predictions of infinities, in agreeing with QM. Thus, mathematics of proving holographic principle is based upon faulty assumptions ! 22:50 Thus Uncert. Princ. & G.R. LIMIT amount of info. BUT is based upon the walls (volume) of region coinciding with the NON-real (physical) event horizon. A black hole can always have additional mass added. 24:00 Fixing the VOL = black hole horizon IMPLIES -> So, holographic principle says how much info. fits into a fixed event horizon volume. But that is not the same as how much information fits into a fixed volume ! !! Which is the real interesting question. A question which still has infinity as the answer under assumed continuous space ! !! 25:30 Un-answerable question ? the room still exists, what say we open the door and pull some debris inside ? Clearly more info. in the volume than allowed for by Ev.Horiz 30:00 Black hole theory. Info related to surface area of Ev.Horiz 30:40 Black hole volume not defined well. THEN HOW CAN WE USE IT TO ANSWER OUR QUESTION ABOUT VOLUME and INFO. ? 49:30 Addressing the difficult problem above. ZERO VOLUME ! !! = LESS COMPLEX Doesn't really explain.

Nature, we learn during this talk, is eclectic in the ways that it guarantees that there is a maximum information content corresponding to the surface area of a region. As with the uncertainty principle, where something always gets in the way of making a more and more accurate determination of the position and momentum of a particle, likewise we have a limit on information in a room, arising from various difficulties.

"All of the energy and matter that existed still exists. Matter does not create energy of itself. Matter enables energy to become manifest".

0:22:34 There must be some constant missing in R=GM, because dimension is not the same on both sides. I think it is 1/c^2. Aside: I'm sure nonnative speakers will be thankful for his nice pronunciation.

It seems to me, that since all event horizons are just 2-D representations of a 3-D object at its' core, we are all just smears across a 2-D event horizon, I call it the "Hyperfilm", located, somewhere just beyond "OUR" 4-D space-time. :) I'm saying we are inside a black hole right now.

Actually we are in a “white hole” which is the other side of a black hole. The Big Bang was the singularity of a super massive black hole that swallowed a massive universe. We are on the other side of that , which is why our “universe “ keeps expanding in an accelerating fashion.

Great video! Fantastic message!! I need to watch this video once more... "Man and his dreams are made of the same matter". I think this is from Shakespeare. I loved to read "Dreams Of A Final Theory" from Steven Weinberg. I read it twice! This video deserves certainly a true coming back!

Is there a good book that elaborates on these concepts? Especially the stuff about symbolically representing the physical objects in a give space (i.e. how quantum physics relates to information theory)?

you are wonderful ,THANKYOU

A String component has an energy limit, though it's structure takes up space projecting an Area.

Awesome Vidoeo..

Thanks for clearing that up, the nature of the assumptions behind the holographic principle. It seems very much predicated upon the acceptance of infinities and singularities attached to ideas of gravitational collapse. Ideas I see no sense in accepting. In fact 20 yrs ago I read, the production of singularities in theories was a good enough reason to reject - because it leads to 'anything' happening, ... I would now add, .... like thinking the information content is limited by area / aka the world is a hologram ! Finally I would add, the 2nd law of Thermo isn't a real law, in the sense usually meant, just a statistical observation about likelihood, so building too much upon it is also a sticky wicket.

AS you scratch the surface, how much entropy has been added?

@TirianB - The large a black hole is, the lower is its density. So bringing together two black holes produces a new larger black hole whose area is twice the sum of the original black holes. That's from R = mG. Twice the mass, so twice the radius, which is 8 times the volume, and thus 1/4 the density. Thus the original room they were in had to be bigger, otherwise it would have collapsed sooner with the two boxes already in it.

In his case though, I think that his movement shows that he is very kinesthetic, so he cant stay still, not lack of confidence. :)

String Theory; every particle is spread out across entire universe, so universe is therefore not really any size as everything is connected. Information is 'projected' from the 2D 'edge' of universe, but since there is no real size of the universe the 2D projector is also 'everywhere'. We are simply then existing as a projected 3D illusion which is sent from a 2D surface. The 2D surface, is therefore the creator of information and we are simply manifest thought/computational forms.

very very interesting!

Weiner Heisenberg called an end for particle physics in 1975, when he realized that vibrating matter must be made of these Standing Waves. A particle is what happens when you build a particle accelerator and now we have string theory, where everything is made of strings or multi-dimensional loop's (A Standing Wave in Three Dimensions) E2 forming a square of future probability as waves come 4pi R2 generating electrical potential within an object compressing E=mc2 decompressing expanding spheres.

R = GM is the gravitational radius of a (rotating) BH. In fundamental units c = h = k =1 as usual in modern physics, so that the missing denominator c^2 = 1.

by "it" i mean from our current position no experimentation can be done that can deduce anything "outside" the horizon boundry. Its like a reverse black hole that depends on your position.

Thank you, UC! This was great (despite using an OHP) ;)

However the discussions and illustrations and commentary will expand to include Physics, Astronomy, Mathematics ..as well Linguistics. I am glad I found this very informative and fresh ( unorthodox) video presentation dealing with these very relevant subjects with a veiw toward Unification. ! I hope those who watch this very stimulating thesis will care to consider my postulates along these lines as well.

A few questions ... (1) How small can a black hole be ? (limits?) ... (2) How large of a sphere of ~U235 would be required to create a "smallest" black hole? (3) How does this "initial/terrestrial" mass-density relate to energy required for collapse? (4) Once this tiniest hole is created, can it be "un-done"? (5) If a micro-hole cannot be un-done, can the permanent gravitational attraction be "harnessed"? ... How does this "leverage" compare to permanent magnets? (6) Mobility? Spin?

Love it!

Another example of a foolish videographer destroying a presentation by preventing the viewer from seeing the slides. The videographer sees content only in the face of the speaker and nothing in his words and writings. Too bad.

You can only fill the room if the size of the particles is defined. Theoretically, there could always be a smaller initial particle.

Getting warmer

The quark gluon plasma was a state of matter that existed before inflation, allong side the electroweak force. It was the breaking of symetries between these forces that drove inflation (as well as the matter, anti-matter, billion to billion and one difference), into the Universe we all see and love today. Maybe, someday, the symetry between space and time will also break, driving the next inflationary phase. A new Big Bang?

Please tell me I'm not the only one who sees the parallel between the event horizon of our 'visible' universe and the event horizon of a black hole. Is it not possible, that our known universe is itself the 'inside' of some huge black hole, and that black holes within our universe are fractal iterations of the same?

Is there a Q and A for this that got cut off at the end?

to specify everything, that is to say everything has an adress, nonlocality with spatial adresses, and also beyond space adresses as in black holes..

MAJOR_NOTE:Entropy of the given space must be less than or equal to surface area of space which is the same as the surface area of the blackhole.

So when he was talking about compressing the room into a planklength, it would collapse into a black hole before that could happen. is that because of that principle from before? where more energy is required to make something smaller? and that energy equals mass? or is that due to something else? btw the question is at 43:50

There is no limit to the number of letters you can put in the room. Infinite number of particles can occupy any given point.

Excellent talk - I'm new to this holographic principle thing, this made a lot of things very clear for me. Not sure what he's getting at from 52:00 to 54:00 though... I'm guessing that he's saying that it doesn't seem to be possible to imagine a physical observer consistent with general relativity who could measure a loss of information or a decrease in entropy, which suggests even more strongly that this principle is remarkably solid. If so, then I'm happy to take his word for it. :)

3. I hope I’ve said enough about David Sereda and his Galaxy Clock video (on Netflix) to spark others’ interest. I need to watch it again. I found it fascinating - though I clearly lost the jargon. Anyway, please forgive and check it out if you find the time. Oscillations, not distance traveled - that frequency change somehow alters gravity/time at the center of the galaxy - and it goes black when the oscillations increase as distance traveled begins to decrease as the spiral tightens…

Very insightful. Lucid and intellectually transparent. I have a lot to say about these strange informational expansions and contractions as well. I approach this subject through a geometric framework in an ongoing series of videos that i have posted to u-tube. I express similar things; following Raphaels line of reasoning, by examining geometric patterns existing in nature and as related very interestingly to human anatomy as well the surface geometry of all things found in nature.

0. I look forward to locating some of your videos. You suggest you’re thinking thoughts. I’m interested in viewing them. Meanwhile, I have this hologram idea that’s based on rainbows and photons that refract light as a prism and contribute to the holographic rainbow effect. But what of all the other photons? Where is their imagery projecting? I will consider this. Unless someone else wishes to do so. I’ll be interested to check out your videos - thanks.

@sodaslacks The property that information in a given 3-dimensional space can be encoded on a 2-dimensional surface is holographic. Many conventional holograms consist of information encoded on a 2-dimensional surface, which, when illuminated properly, produces a 3-dimensional image.

Listen to Thomas Campbell too on metaphysics with his My Big T.O.E. (theory of everything) What exist beyond religions, science and all human speculations, what is the true reality? Is consciousness...that works with symbols and meaning. The reality is digital and information. And the best body of work that defines it is METAPHYSICS..

Well said.

What would the formula be for figuring the amount of wear to the soles of his shoes occuring during this presentation?

@UCtelevision Perhaps you could have Dr. Susskind lecture on this subject? This was interesting, but unless you already are familiar with the Holographic Principle this "introduction" is not so "friendly". Thanks for the lectures.

I meant that what a good science (or whatever) communicator does not depend on the vehicle of communication. A "poor" one will benefit a lot on using powerpoint. My PhD supervisor used overheads when everyone was using power points and he was great! The other way around happend at the same time with other teachers. The question was nor if UC Berkley could afford or not a powerpoint and projector. The question was if it was necessary for this talk to be great...

That explains it. Thanks.

I didn't catch that he was suggesting that the information was written on the event horizon. I think the point is that the entropy (equals information capacity) of a black hole is no larger than the surface area of the event horizon in Planck area units.

(03:00) The geometry of spacetime and the information content: a mysterious connection which could be an accident, but it is not!

An overhead projector with transperacies, you write with marker it displays on a screen using projection lamp

2. So, as a galactic arm spirals inward and spans VAST distances, it behaves like a motor’s winding in terms of electromagnetism. Light begins to travel greater distances in the same amount of time as the galaxy’s arm tightens in its spiral toward the center (black hole) of a spiral galaxy. It’s got to do with the frequency of the light being exponentially increased as the distance that it must travel becomes exponentially smaller along the inward spiral of the galactic arms.

@DANEMAN5 yet it looks clear and works well and efficiently. Why waste bandwidth on unnecessary detail?

What is that he is using? Is it a projector?

3. I have begun thinking of our human reality as the Visible Light Reality (VLR). It helps me acknowledge that human beings TYPICALLY perceive light information that is occurring within the VLR perceptible to human senses. And that does not mean that ultraviolet reality is nonexistent. Simply alter the frequency of light vibration, and what was visible a moment ago - seems to disappear! By vibrating faster than visible light! Matter can surpass light speed by way of altered frequency!

4. … (like the inner v. outer distance of wire in a motor’s winding, where one revolution of a wire is longer on the outer part, and much shorter at the interior portion - so the electricity / light travels many more revolutions per second at the interior of the coil than at the exterior - and those revolutions equal oscillations???). Moments like these, I wish I were much more brilliant! Of course! But I make do. …be well, and I hope you’ll find Sereda’s work and enjoy it. I’m around.

Would it by necessity have a relationship between Boussos's desire to get an accout of the information content of the room he is in and the information his mind is absorbing through his several senses from the near environment?

I like this guy.

1. I get ur mssg now. OK, if I misspoke, I’m sure it wasn’t the first time today. Please forgive, and know I lack scientific jargon. Ultraviolet light may not travel faster than light, but I was referring to frequency of oscillations - not distance traveled. So, it vibrates faster than visible light in order to travel the same distance in the same amount of time - yes? David Sereda is a physicist guy who makes his Galaxy Clock invention and Gravity as a function of frequency very clear. :)

use an aquarium and colored marbles. each colored marble represents a different construct of the item in the room. For example green marbles are trees, brown can be a house, orange can be a person, blue can be sky and light blue can be air. note marbles reflect light and are the atoms and everything even though different are made up of the same thing; atoms....

How much DNA applies for how much information content is there in nature? (05:52) That's what I am really asking! And what that means in terms of very fundamental principles?

The question is: What's the relation between information density and the necessity of DNA and then the emergence of life? What's the pattern of principle behind it which is certainly connected with the principle of equivalence?

@phrankus2009 I don't have all of your answers, but a Planck-mass black hole would evaporate immediately. The Planck mass is believed to be about 20 micrograms. This is effectively the minimum mass for a black hole.

I like the pool cue.

I'm supposed to be revising for AS physics right now, but why would I want to learn about projectiles and stress strain graphs when I could be watching this?

@DCIK you read my thought.

how would the letters enter the Room? Via "accellerated" Brownian Motion? As "condensed" stacks of ordered letters ie all A's stacked here in this area of space down to Z? As any or all alphabets of human culture? How about all possible letters perceivable, past, present, and fure, even of non-existent letters? Are these Letters cxounterparts to Imaginary numbers? How about U.F.O.- Alien- E.T. Letters? Could Raphael Bousso's Room of Letters cocsist of any and all Letters(of correspondance)?

How does this fit in with dark matter/dark energy? I we think of our universe as that projection, what can we infer from what we know about fractals? These are questions that fill my waking and sleeping hours.

who created a projection?

Space is a calculation done by consciousness in order to interpret the data that comes into it. It is a mathematical function defined by the larger consciousness system (LCS). Scientists are expecting to see the edge of the Universe and they will never find it because is all virtual and it generates itself as long as you stare at it. It’s like AutoCAD model space. It’s infinite and a virtual generated space. As crazy as that sounds the Space is the same and consciousness is the computer.

@thinkahol Observe that the event horizon only exists for an outside observer - a singularity for us. A special property of this outside view is that anything that is tossed into a black whole freezes in time on the event horizon and thus for us the information is preserve while from the stuffs viewpoint nothing special happens and all information about the stuff is eventually destroyed in that pathological singularity but that is okay as that event never takes place for us outsiders.

Well, I appreciate your speculation and I take it as an option, however I will need some solid evidence, but very plausible. I maintain that pp improves in the same way you wouldnt use a typewriter, and its an electronic medium allowing to share.

A Plank length squared is what you use. Why not a Plank length cubed to represent space. The model of a membrane changed with the cube. Area becomes tiny energy volume packets.

@shaggyhag if the camera was zoomed out you wouldn't notice as much.

How many ways can a black hole deform? what are the accepted shapes in differentiation, like stem cells, that can only take so many differing evolutionary tracts based on energy, and some stuff inside the stem cell, in which the bath of energy has shifted the locales of certain functions, that are still suppressed, but evident in the growing energy bath...

It's a point. I use powerpoint and projectors sometimes. Other times I prefer not to do it. I guess thats an option. Powerpoints distract the attention from the speech and the speaker. They are important if you need to present series of complex pictures. They are useless if you want to explain an idea using maths in a blackboard. And if you are an excelent communicator (which I am not) the audience will thank you for not using powerpoints!

I wonder if you'd be interested in David Sereda's Galaxy Clock video. He did it with Dan Aykroyd in the context of ultraviolet (and hence faster than light) UFO technology. But the crux of the message for me, was that Black Holes appear black because the frequency of light/mass/gravity/electromagnetism is altered to beyond light speed -- ultraviolet. It's there. Humans simply no longer perceive it at such frequency, speed, vibration. I don't know about radiation. You take their word 4it?

Could Einstein's Theory of Relativity imply That Expanding the Room's Space AND Shrinking a Person in it to smaller size are relatively speaking THE SAME THING? EXACTLY the same thing, or ALMOST the same thing? Is the outside Environment i.e. the Fielded Domain exterior to it and "enveloping it a limiting or even an "antithisis" to this Equivalence? For Example :shrinking a Student in this ClassRoom of Professor Raephael Bousso in Outer Space is more equivalent than on Earth at Berkley?

What a darwinian selected mutation could ever have got to do with specifying the state configuration space of a certain environment?

@WoundedEgo The singularity is small, and can't actually be seen or otherwise detected in any way. The size of the event horizon will be proportionate to the mass of the singularity. The singularity that existed prior to the big bang wouldn't actually have an event horizon, for two reasons. One, there was no matter or space by which to define the event horizon, and two the physical laws that govern our universe were not in place prior to the big bang. By mass, the big bang singularity is bigger.
