Talk about challenging my sensibilities!

The whole concept would be much easier to laugh off, if the noise plots
didn’t match Hogan’s predictions.

I'm smart about some things, but I can't fathom this at all.

I felt like a dummy reading this.  It just doesn't make sense to me.

The black hole information paradox is amazing in itself.

Just remember to apply the flipperlips therom and the square root of 16.  Coagulatrons and Adheseneaters squared with cube resistance is right on the money with this.  WOW!!

I'm assuming this has nothing to do with Hogans goat.

It's a complicated subject, but the article does a pretty good job at translating this for the masses.  I think Marc hit the head on the nail, the very idea challenges your sensibilities.  That is the reason I find it fascinating, I guess.

This use of the hologram as a model for the universe is very specific and particular, but people have been making somewhat similar statements for a while (without proof). The Dancing Wu Li Masters, Crack in the Cosmic Egg, and Holographic Universe are 3 books that come to mind as proposing the universe is a hologram. Also, Plato used the metaphor of prisoners chained in a cave, watching shadows, thinking that it is reality ... he certainly didn't have the word hologram in his vocab, but the article you linked to reminded me of that.

He showed that the physics inside a hypothetical universe with five dimensions and shaped like a Pringle is the same as the physics taking place on the four-dimensional boundary.

Question: Does a pringle with only four demensions have the same, more or fewer calories than a pringle with five demensions?


Quote:
It was as if the beam splitter had an extra sideways jitter.

I find I also have an extra sideways jitter from eating too many pringles!

Lastly, from now on I am going to measure my exercise program in Planck lengths.  While I may not loose pringle weight any faster, the larger numbers will make me feel better...

Thanks for the article Shawn. I found it facinating.  Seriously  8-)

Writer Marcus Chown does a good job of explaining complicated things to within reach.  His 2006 Quantum Zoo does a good concise job with relativity.  He gets into black holes but doesn't make mention of holograms.

The article also points to the ongoing kind of battle Leonard Susskind and Gerard 't Hooft have with Stephen Hawking.  


Quote:
In the mid-1970s, Hawking showed that black holes are in fact not entirely "black" but instead slowly emit radiation, which causes them to evaporate and eventually disappear. This poses a puzzle, because Hawking radiation does not convey any information about the interior of a black hole.


Theorists have since shown that microscopic quantum ripples at the event horizon can encode the information inside the black hole, so there is no mysterious information loss as the black hole evaporates.


Susskind's book from 2008 The Black Hole War has this stuff all spelled out in the best readable detail, with most definitely holograms mentioned.



Interesting that a modern version of the beam splitter, interferometer, invented by Albert Michelson is used.  Michelson used it to try to prove the existence of the very controversial ubiquitous ether in the universe and put the death knoll on that notion, first at the lab of Hermann von Helmholtz, Berlin 1881, then more conclusively with Edward Morley in 1887.  Nobel winner Michelson may have his invention possibly pointing toward another Nobel in many years to come.

well... it certainly points to a possible explanation for why I've been feeling so grainy lately.

I loved the article... very fascinating... thanks for posting.


with warm regards,
Tony

If verifiable this would be as big a discovery as the yield from the supercollider at CERN. Thanks for posting as I would have missed it entirely!
