- UC Berkeley's Raphael Bousso presents a friendly introduction to the ideas behind the holographic principle, which may be very important in the hunt for a theory of quantum gravity. Series: "Lawrence Berkeley National Laboratory Summer Lecture Series" [3/2006] [Science] [Show ID: 11140]
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 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.
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!
This man is an amazing "teacher". Very informative!
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!
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 ‘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.
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.
Very interesting ! Thanks for posting.
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?)
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~!
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.
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!
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 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...
Thanks for the explanation.
It took 25 years for me to understand the beauty of math. Thanks man.
(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!!!
Thank you, UC! This was great (despite using an OHP) ;)
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.
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.
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.
A String component has an energy limit, though it's structure takes up space projecting an Area.
@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.
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. :)
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
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)?
AS you scratch the surface, how much entropy has been added?
you are wonderful ,THANKYOU
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!
You can only fill the room if the size of the particles is defined. Theoretically, there could always be a smaller initial particle.
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.
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...
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.
Awesome Vidoeo..
very 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!)
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.
Getting warmer
@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.
to specify everything, that is to say everything has an adress, nonlocality with spatial adresses, and also beyond space adresses as in black holes..
Love it!
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.
@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.
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?
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.
"All of the energy and matter that existed still exists. Matter does not create energy of itself. Matter enables energy to become manifest".
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.
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?
Is there a Q and A for this that got cut off at the end?
An overhead projector with transperacies, you write with marker it displays on a screen using projection lamp
@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.
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...
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.
@DANEMAN5 yet it looks clear and works well and efficiently. Why waste bandwidth on unnecessary detail?
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.
Actually we're in a brown hole.
Is there, therefore some rastering algorithm which projects the information in 3D onto a 2D surface?
+thrunsalmighty No. The other way around. There is some rastering that projects the 2D reality onto a 3D model.
Bousso says at about 23:25 that there is an upper limit on the amount of energy which you can put into the room. But I don't understand why. His upper limit seems to be black hole density - the point at which light (the fastest thing!) can't escape, but why is this an upper limit? Why not put even more mass into the room? It may be futile from a gravitational point of view (one is not going to stop anything else from escaping once one stops light) but I don't see why he calls it an upper limit.
Or wait, is the upper limit provided by the uncertainty principle? Yes. One can't put more mass in because one can no longer *know* that one is putting more mass in to the room since one will not be able send light in, and have it bounce out, to check. It is a bit like saying "it is impossible to make a prison more escape proof than an unescapable prison" Once the prison is unescapable, then making the walls twice as thick does not make the prison more unescapable. It was already unescapable.
Is it kind of an ontological wall or ontological limit? Normally we don't think that knowing prevents doing. If I have a bucket and I turn on a tap, then just because I don't know the flow rate does not prevent me from filling up the bucket. But in this case there is a logico-visual ontological limit. It is visio-logically impossible to know if one has added more mass to the room once light can't bounce out because one will not be able to observe more mass. Once one can observe more mass (a visual limit) then it becomes impossible to say truthfully (a logical, or linguistic limit) that there is more mass, perhpas.
Of course, if one is adding mass to the room, then one can claim that the room is getting massier but it may be that there is a wormwhole in the room so that the mass is leaving by the back door. One can not know for sure, or rather knowelge of more mass in the room stops at the point at which light cannot leave.
[Logic and vision meet to provide a sort of liars paradox with a face, not "All cretans are liars" but perhaps "All cretans don't have mouths"? (I am not sure if the statement "all cretans are liars" has a visual aspect too. It is only a paradox if it is implied that the person saying it is a cretan)]
When he says that there is an upper limit on the *information* that can be stored in the room then that is a lot more plausible than there being a limit on the mass. The upper limit on *information* stored in the room can have an ontological limit because information is ontology. I can't store more information if I can't know it because information is about knowing.
Mass on the other hand!? Even if one can't know, can't one do? In generally there is a blurring of the distinction between information and reality (letters and air molecules, information and mass) which hides the fact that this is a panpsychist/phenomenalist onto-physical theory. Not that there are or should be "pure physical theories" but when ones physics is based upon ontology, upon the possibility of knowing, then perhaps one should make this clear so as not to confuse schoolboys!
Holographic theory is very much like relativity.
Einstien read Mach, a panpsychist or phenomenalist, and then proposted special relativity. The reaons why nothing can go faster than light is because "the unverse" is our explanation of our sensations. Or fastest sense is light. If the universe is understood as "explanation of sensations" where senations are the stuff, sure nothing can go faster than our fastest sense, light.
Applying the same logic to bodies, once a body, a room gets so heavy that light can't escape then sure, that is a limit for the same reason: it is a ontological / sensational limit. And (I have already seen another video by Susskind) if this leads to the realisation that the mass proportional to the surface area, then sure, the world is holographic because the theory starts from a panpsychism (sensation is stuff) and will end there. If the stuff of world is sensation then sure, it is 2 dimensional. The world is two dimensional because it is an explanation of our sensations, which are two dimensional. The world is two dimensional, because it is our visual fiield, which is two dimensional.
Bousso could have made his talk a lot shorter!
Other random observations.
The Bousso dance is interesting. He always swirls like an electron when he presents. Steven Heine moves about quite a bit too. (So do I but I do not belong in the list) And Professor Bousso used an overhead projector in 2006! Very non digital! Very visual.
This reminds me a lot of Jackson's "What Mary didn't know" Each air molecule is like a letter! Is each colour a letter too?
It is very strange that a theory that ends up being so visual -- the universe is two dimensional, the universe is flat, the universe is broadcase in planck definition, the universe is a picture -- started out (at least in this explanation) seeing the world as made up of information, and letters.
The Japanese writing at 5:30 or thereabouts is genshi (原子) or atom(s) written in atoms.
timtak1 He specifies that for a given region of space, there is a limit of energy, that may be contained within it. Coincidentally, this is the boundary by which any additional energy will facilitate the formation of a black hole.
en.wikipedia.org/wiki/Bekenstein_bound
Thank you.
I think the limit will be given by M = r e / 2G (from the equation for escape velocity) the integral of which depends upon r squared not r cubed.
I doubt that it is a coincidence.
I am not sure of the difference between your boundary and
en.wikipedia.org/wiki/Schwarzschild_radius
Which 'coincidentally' corresponds to the radius and mass of the visible universe.
+Oners82 Yes, but why does that limit per unit volume exist? Both he and Susskind in another video say that something like "we know that the mass varies as the square of the diameter of the black hole" and do not give their reasoning, but it seems to me that it is as simple as rearranging the equation for escape velocity, inserting c (the speed of light) and we see that M= r e/ 2G which when integrated, to see the way in which the mass increases with radius, we see that it varies according to r squared not r cubed. In other words, mass will vary as according to the volume not surface area of the black hole.
+Oners82
My question is:
Is the reason why the limit varies as the surface area (r squared), and that therefore we live in a holograph, explained as simply as the integral of the equation for escape velocity M= r v /2G or M= r e /2G?
I did not mean to say that it varies with the volume. I am sorry. You said (in your previous comment" "He was talking about a limit PER UNIT VOLUME" and I used your words. I am aware that they say it varies with the surface area (and hence the holographic principle).
Yes, I am agreeing with them. And yes, I did changing my question, sorry.
I am just wondering whether the reasoning behind the holographic principle is as simple I am suggesting above.
+Oners82 Sorry! And thank you very much for your patience.
It has been a long while since I have attempted any physics.
How did I get the equation for escape velocity wrong!?
The equation for escape velocity is here
en.wikipedia.org/wiki/Escape_velocity
And substituting in c the speed of light for the velocity.
c = root of 2GM/R
squaring both sides of the equation gives
c^2 =2GM/R
multiplying both sides by R gives
R e^2 = 2GM
Dividing by 2G gives
M= c^2 R/2G
(I did not write c squared last time, a mistake but since c is a constant value, c squared is likewise.)
This is the equation for the relationship between the mass and the radius of the event horizon from which light cannot escape.
It has been 30 years since I have done any differentiation of integration but it seemed to me that integrating
M= c^2 R/2G
will give the equation for how the mass builds up with increasing R but I am probably speaking out of my posterior.
Alternatively R= 2GM/c^2
Again, some simple calculus should give the equation for how the radius of the event horizon of a black hole (which is also perhaps the size of a black hole) changes with increasing M, no?
Please do not go to the trouble of attempting to write equations in a TH-cam comment, but if you have a URL for the research paper that shows the relationship I would be interested
Thanks again for your patience.
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?
What would the formula be for figuring the amount of wear to the soles of his shoes occuring during this presentation?
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.
smiashing room in bh means possibly nonlocal transferrence into bh or a collapse star...
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.
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)?
@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.
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?
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…
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.
@shaggyhag if the camera was zoomed out you wouldn't notice as much.
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.
Hmm. I always assumed that entropy had a problem with black holes.
We used to think that the universe would eventually start to contract. (we know better now).
But I always wondered what a contracting universe would do to entropy.
I still wonder. But maybe this helps.
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.
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.
@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.
There is no limit to the number of letters you can put in the room. Infinite number of particles can occupy any given point.
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?
The text at 5:40 written in atoms is in japanese and it means atom
In his case though, I think that his movement shows that he is very kinesthetic, so he cant stay still, not lack of confidence. :)
What is that he is using? Is it a projector?
That explains it. Thanks.
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?
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....
@DCIK
you read my thought.
How can a black hole be the size of "this room" if it takes a minimum ammount of mass for a black hole to form to begin withß
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. :)
No, as Lenny Susskind explains in one of his videos at the world science festival 2011 we are in an inside out sort of black hole called de Sitter space created by anti-gravity dark energy. Stuff flows out of our future event 2D horizon we are inside of and are hologram 3D images of.
What a darwinian selected mutation could ever have got to do with specifying the state configuration space of a certain environment?
Well said.
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?
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.
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...
Fascinating! Interesting!
But is it useful?
What if the world is discrete outside the event horizon while it is continuous inside... so the three parameters of a blackhole can be used to represent infinite combinations of parameters outside.. so there is no information loss.. something like there are far more real numbers than integers.
I like the pool cue.
@shaggyhag lol after reading your comment i actually thought about using my video stabilizer on this video.
@thejahoflife
You can offer that amount of money and refuse any payment with regards to semantics since the scientific prove is not a legal term. And since you don't want to actually pay the money there is no incentive to adjust the terms in a way that do constitute a legally binding challenge. You can just keep up the original page forever.
Got it?
I guess it can collapse into that size. But it's a good question, since a BH can only get bigger, I wonder what is the minimum size it can have at its birth...
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?
