what IS the Casimir effect?

[sawyersgirlfriend]

WELL,If anyone else is as bored as I am waiting for Lost,
(Sigh, I support the writers but I miss my show.)Then perhaps they're thinking of all the details just as I am.


I found an interesting vid on youtube that explains the Casimir effecthttp://www.youtube.com/watch?v=EEaoBbkwYXM&feature=related, I hope you enjoy.

wait till I have a few brews...

but for starters.. the casimir effect is the force between two objects..

so what the heck are our two objects for the island to exzibit this effect ?


my guesses..

1. the island
2. the magnetosphere



but if you could take the negative pressure found within the casimir vacuum,
you could stabalize a shape with the negative pressure, ensuring it does not contract and possess a constant..
(negative pressure repels, so it adds a positive pressure, oddly as it sounds)
(& a positive and large cosmological constant will also add negative pressure)

plugging a black hole.
and in theory, anyone approaching would not see beyond the event horizon of your little island universe.

you would be invisible

kind of like this..

That picture makes sense.

Did you guys even watch the Video?
It went into some detail about the scientific uses of the Casimir effect.

In short It could be used to create a time machine.

Watch the vid it's REALLY interesting .
Very informative for those of who aren't physicists .

Not that your wrong.. you're the resident genius :detective

This was just SO interesting,
And as I said it went into it's use for time travel.
Can anyone say multiplying bunnys?

SGF,
I can't view the clip right now because of workplace Internet rules, but I'll look at it later. However, based on what everyone is saying, this is the principle referenced in the sci-fi film "Event Horizon," where a "gravity drive" is created for the purpose of faster-than-light travel. What's discussed there is the use of high-intensity magnetic fields to harness a "singularity," a friendlier word for what's more often called a black hole.

As I've noted on many threads, there's a major shout-out to "Event Horizon" on the Blast Door Map from Season 2 of "Lost," in which a Latin phrase appears that's quoted from "Event Horizon." The phrase means "Save yourselves from Hell." In the film, it's part of a transmission from the original occupants of the missing space ship powered by the Gravity Drive (which apparently used the Casimir effect to contain an artificial black hole). It turns out that the ship has not been across the galaxy at light speed or even back in time. It's been to another dimension of malevolent consciousness and a malign entity has come back with it with the power to create nightmares, alter perception, and possibly alter reality.

Kind of an interesting out-of-the-blue reference on the blast door map, which also references Cerberus, given the habitation of the island by a Smoke Monster and/or Jacob. Not to mention whatever the button is preventing from happening.

Did the button ensure that the Casimir effect was ongoing, so that some sort of powerful experiment at the Swan (but not visible to us) wouldn't collapse and cause the sky to turn purple? Not that the sky turning purple was the most dire effect, of course.

Hi sawyersgirlfriend, I don't recall casmir effect being mentioned in the show.

(I'm aware that it's been mentioned already in some theory threads that we have, but it's too late to do anything about that now).

Don't get me wrong, I really enjoy the science aspect of this - but this thread is probably spoiler-ish because it's about something mentioned in a podcast. I'll have to move it to Spoiler Theories, even though it's not a theory as such. Please continue the discussion there. Thanks -mav.

Brian, if you've got a better home for it, feel free to relocate it.

IT was in the Orchid Video ,on the ABC website, NOT spoilerish At ALL
not if its THERE.
... check it out..it's good.
there are also some little lost vids called "missing pieces"
they show things that happened when we weren't looking .. pretty cool stuff

I watched the video, interesting stuff. The bottom line seems to be that the Casimir Effect is something that would enable harnessing a wormhole, where the two ends of the wormhole occupy the same space, but different times. Essentially yes, a time machine.

Seems very in keeping with The Orchid video. At some point after the film was made, #15 went through a wormhole that sent it back in time, and it appeared as the film was being shot, while Halowax was holding its past self. Halowax was concerned that the future version of #15 have no contact with its past version, because if the future version in any way altered its past version, a temporal paradox would have been created.

Geez, Yung, that looks like a uterus.

totally, that's why I thought this video was so relevant

moved to spoiler theories and died a quick death, eh

now the producers have said it is "cannon" - the Orchid video

hen again, I suppose this stuff was discussed when the vid came out

Casimir effect (kāz'ə-mîr') Pronunciation Key
The effect of a net attractive force between objects in a vacuum, caused by quantum mechanical vacuum fluctuations creating radiation pressure. The radiation can be thought of as an atmosphere of virtual particles. The amount of radiation pressure on the objects is decreased in the gap between them, due to limits on the wavelength of the radiation in the gap. The gap is thus an area of lower radiation pressure, drawing the objects toward it. This force is strong enough to be of great importance at scales encountered in nanotechnology. The Casimir effect is named after Dutch physicist Hendrik Casimir (1909-2000).
