The Energy of Empty Space != Zero 362
Raindeer writes "Lawrence Krauss (well-known physicist and author of The Science of Star Trek) invited a group of 21 cosmologists, experimentalists, theorists, and particle physicists and cosmologists. Stephen Hawking came; three Nobel laureates, Gerard 'tHooft, David Gross, Frank Wilczek etc. He wrote about the conclusions of this session in Edge; in short: 'there appears to be energy of empty space that isn't zero! This flies in the face of all conventional wisdom in theoretical particle physics. It is the most profound shift in thinking, perhaps the most profound puzzle, in the latter half of the 20th century. And it may be the first half of the 21st century, or maybe go all the way to the 22nd century. Because, unfortunately, I happen to think we won't be able to rely on experiment to resolve this problem.'"

Guys, it's early Monday morning here. When I see a fragment like that, my very-tired brain makes be go back and read it again until it makes sense. Then, because I'm not awake, I don't catch that the only thing wrong is that there are two "cosmologists" in there. Then I have to go back and read it again... then, because I'm not awake, I don't catch that there's two "cosmologists" in there and I have to go back and read it again...
You get the picture. I was going to make a point or say something a little more witty, but it's early Monday morning here.

In which other web page do you think you will ever find a phrase like that? I really love Slashdot today. Talking about "conventional wisdom" in "theoretical particle physics".

I can't show you how it works - that's a secret I want to keep until things cool off enough for me to patent it. But rest assured, it works. You can drop by and see the spinning plates attached to it. They've been spinning for eight months with no added power.
Yes, I did build it entirely on my own, using the vast knowledge I gleaned by sitting in on engineering classes two or three times a month.

Albert: Well, it may be cold and wet here, but at least we can't get any lower! I guess that is some sort of consolation.
Crackpot: What are you talking about? We're still filled with potential energy! If we could harvest the potential energy we could get from going a foot lower, we could use it to boost our way out of here!
Albert: Um... no.
Crackpot: What do you mean? Do you work for the oil companies or something?!
Albert: The amount of potential energy you have depends on where you define your lowest point. Typically we set the "zero" point to be the point where you can't fall any further. Since you can't obtain any energy by any means at that point, that means there is no potential energy left.
Crackpot: But what if we dig down another foot?
Albert: Do you have any idea how much energy that would require to do that?
Crackpot: Fine, we'll dig down 20 feet to extract more energy, and that will pay for the energy expense of digging.
Albert looks confused. He thinks he might be missing a subtle joke. He decides that he isn't deficient in humor -- his companion is deficient in brainpower. Albert unfurrows his brow and tries to talk some sense into his friend.
Albert: Ok. Let's consider two situations. We've got our situation right now -- we're at the bottom of a well with no way out -- and another situation. In the other situation an evil man is dangling two jet-packs on a fishing line right above our heads. The man will always pull the jet packs out of our reach whenever we try to grab them. The man will never get tired and he will never let us have the jet packs no matter what we do. No matter how long or hard we try, we won't get the jet packs. Question: is it easier to get out of the well in the first situation, or in the second situation?
Crackpot: What does this have to do with getting access to our latent potential energy?
Albert: (sighs)
Crackpot: I have a shovel and some rubber bands. You try to talk to the guy with the jet packs while I dig.
Albert drowns himself. Fin.

A real scientist doesn't pay for a hooker. He'll build himself female androids / re-animated constructs / golems, depending on if he's living in high-tech future, victorian times or D&D fantasy realm.
