"The World As A Hologram" - Prof. Raphael Bousso (1 of 3)

[acuaman42]

I suggest to viewers to read the latest book by Stephen Hawking, THE GRAND DESIGN. In it he explains almost the same as this speakers says but also adds that there is not just one universe but thousands of millions more. The book is easy to read for anyone at college. The only problem for some people is that the final conclusion of Prof. Hawking is that there is no GOD needed for the formation of any universe. This does not like to all religion leaders but who cares about them.

Because the sources of gravitons are subject to inertia and gravity is possibly bound to electromagnetism at the higher end of the energy spectrum, there is likely no causality violation necessarily involved in gravitons being slightly superluminal, IMO.

[CACBCCCU]

Supposing there's a random sea of gravitons and each is either raising space a bit or lowering it, where lowering it on a 2-d model universe matches the elastic-sheet model of gravitational potential, while the full raising/lowering cycle for each graviton is in lightyears. I assume in the lower limit a lightspeed propagation of gravitons and a source always emits gravitons at the positive maximum of the cycle. A spectrum of gravitons is possible, and I'll suppose gravitons can form into light.

[CACBCCCU]

For "patterns in nature" useful in explaining quantum gravity, how about ring galaxies such as Hoag's Object? I'm guessing the ring diameter is defined by ultralong-wavelength core gravitons, with the ring sitting on the boundary between positive and negative gravitational phases, giving 3/4 a wavelength between ring and core, for a graviton wavelength of about 75,000 light-years.

Seems to me the core+ring form arises by simple evolution from a highly random distribution using this form of QG.

[anarchy3E]

why does he stutter al the time? is this his first lecture? does he need mommy to hold his hand?

one would expect some eloquence from a mother foking profesor, shit, profesors have gone to the dogs

[thefullmonte03]

Maybe he has a speech impediment asshole. He is a professor in physics, not in public speaking, or the english language

[whitenightf3]

In some sense man is a microcosm of the universe; therefore what man is, is a clue to

the universe. We are enfolded in the universe.

David Bohm

[humanist7117]

Very clear exposition of a complex and difficult concept.

[madderscientist23]

fascinating video incidently!! :)

[madderscientist23]

Hmmm, moving avatars are clever, but annoying. Can't wait for the novelty to wear off so that they are no longer used and, therefore don't detract attention from the subject matter (or make u feel queasy) :)

[rohelinetee]

If anybody is wondering, the symbols written using atoms are in japanese. They are pronounced "genshi"（原子） - which means atom or atoms(there is no prular form for nouns in japanese)

[CheeezMaster]

i love gravity.

[CheeezMaster]

the russians were right.

part1

Ill probabbly get alot of negative comments/ratings for this, but i didnt get much out of this, i understood it just fine dont get me wrong, but its nothing i havent really covered before. Just because i got nothing new from it doesn't make this a bad movie; its great. Personally i perfer RabidApe's movie on "Evolution: created by

[OsyenVyeter]

part2

Satan" i believe it was. it got me started on Rabidape and remains solidly my fav movie from him, i send it to all who debate me and demonstrate a clear lack of comprehension of the LAW of evolution. oh and one more thing: to anyone who doubts evolution on the basis that its a theory ask them this...do you doubt gravity? thats just a theory too

[RabidApe]

did you watch it all the way to the end?

I didn't learn too much in the way of new 'data' I guess, but what 'got me' was the counter-intuitive relationship between information content and geometry.

I'm going to do a 'RabidApe' video about this, probably a short 'overview' followed by my kid-in-a-candy-store-babbling about the implications...

[OsyenVyeter]

All the way? Well you recommended it so I watched it all(the first time). You said you didn't learn much of anything new, but it made you think, that is what my experience was too.

I was replied to by RabidApe! Im taking a snap shot of this! I still maintain your movie was better than this (the "Evolution created by Satan" one). Even if it wasn't quite the same topic. Second favorite would have to be "Help me in my disbelief" -Jim

[healthyaddict]

Thanks for sharing this!!! =) Very interesting!

[RabidApe]

I couldn't NOT put it up!

[thequestionmarkofGod]

I don't always understand it all, but I don't always need to understand to get something out of it.

"An infinite amount of information in any region of space"

I get that, with tears. WOW.

[RabidApe]

(just keep going, it's more exciting than you think!)

[thequestionmarkofGod]

I will, later, just had to take a break. I was overwhelmed a bit. I love this stuff, this little stuff is SO huge of a deal, shit I'm crying again.

Does it ever do that to you? (in a manly way of C)

[RabidApe]

Yeah, it actually has.

It is a truly beautiful thing when some of the pieces click together!

"If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it."

-Albert Einstein

[SandmanOpiate]

Whoever taped that really needs to get in touch with the local drama club.

You put the camera directly behind the projector why? Oh, so everything can be washed out by both the light coming off the screen and the light out of the projector bed.

Duh.

Off to part 2, where things might actually become abstract.

[SandmanOpiate]

and I only say this because the things glimpsed on the screen did not seem insignificant to the words coming out of his mouth.

[RabidApe]

it also suffered significantly in the conversion process.

Check the description and watch the original if it means that much to you!

:D

[ryanomaly84]

this is quite interesting, and the guy is a good speaker, but he is way off on the amount of air molecules in the room being 10^28. 22.4 liters of air, which is roughly a cubic meter, is 1 mole (6.02x10^23 molecules). It is probably safe to assume there is more than 20 cubic meters in the room... so he was WAY off on that one. Even if the room was 2 cubic meters it'd be ~ 10^45.

[RabidApe]

ya gotta watch them physicists and their 'significant digits'!

;D

[Ira0321]

He said, 10 to the 28 is a vast underestimate".

[ShinsengumiTaicho1]

arigatou

[RabidApe]

a pleasure to serve!

[dancingnature]

and a reference to Giacometti as well (his sculptures got smaller and smaller as time went by )

ya gotta love educated people

[Vergil10k]

I don't get any of this but it does extend my mind...in which I think its the speakers intention to do but yeah

Thanks for upload RabidApe you "genius" :P

[RabidApe]

I'm going to do a review of this....

:D

[njpalko314]

Wow, I have a lot to learn before I watch this video.

[NothingIsFact]

I scour YouTube for college Physics lectures, and I thank you, sir, for uploading these.

[andwar99]

Overhead projector and acetates. Old skool!

[AtheistAaron]

Brilliant lecture, thanks for the up, Ape.

[RabidApe]

my pleasure!

this was a big eye-opener to me.

[AtheistAaron]

MIT has made available a great series of classes on electricity that I highly recommend.

[TheBlueFalconX]

I usually read about this stuff on my spare time. I love it.

[ScottishAtheist]

God i love this stuff. I don't understand a single word of it, but I love these brain stretching concepts.

[Rockstar97321]

You don't have to understand it. Just listen to it in the background; and one day, a part of it will just pop out in conversation.

[kaksonen]

what berkeley and mit are doing is great stuff... i spend a lot of time watching these online courses

[premed411]

To see the whole presentation click first link in description box...

then find and click:

The World as a Hologram

(54 min. | #11140 | 3/2/2006)...

then close your eyes and repeat "there's no place like a hologram".

[RabidApe]

thank you! ::slaps himself::

[tarotfest]

i have thought about physics in this way, the infinite scale, the same as the highest number in the world, there cant be, or cant there?....nah, theyre cant, although maybe an aweful analogy.

[jkand]

Would have been lot more interesting to hear about what "Jesus" did 2000 years ago ;)

[Falloutmoon]

Can't wait for the rest!

[RabidApe]

I set the other two uploading when I went to sleep....

grrrr....

::trying again::

[aceserve]

his walking forward and backward distracts from his lecture. I had to hide the window and just listen to what he was saying.

[Kuba022]

Thanks for the upload, although the second link in the description box doesn't work for me (webcast berkeley edu).

[Falloutmoon]

same problem for me here...

[Katalyzt]

He forgot to mention Leptons, Hadrons(Mesons, Baryons) which all interact via strong force, but I get his point.

Katalyzt

[juliecranford]

Yea.

[TOMMYfromtheBRONX]

watched all 20 mins , thanks for putting this up man !!

[RabidApe]

the other 35 are coming!

(you haven't gotten to the punchline yet...)

;D

[wjfox2006]

Very interesting... I love "egg head" topics like this - thanks for uploading :-)

[Vinifera7]

This guy's pacing is pissing me off..

[sweetdaddycoconut]

Wow. I loved it. Can't wait for part two. (:

[CheeezMaster]

7th

[studylikehell]

I love my university and its professors...i hadn't seen this one, thanks RA

[TogetherForPeace]

man this was some really interesting stuff. the prof explained things really well.

[buntpan]

i had to wikipedia "grok." the internet - the only place where you can feel like a dork for NOT knowing what "grok" means.

and now that my english(martian?) lesson is over, it's time to grok these videos for my quantum gravity lesson.

[AdmiralPeacock]

I read an article about this a while ago, interesting stuff.

[smartmusicfreak]

First!!

[smartmusicfreak]

Aww, RA's comments didn't show up till I posted mine.

Third and Fourth then!!

[RabidApe]

links will come in the morning, check my channel - I'm off to bed!

XD

[RabidApe]

first, bitches!

grok it!
