End of the world starts tommorow... (Science Talk Post)

Eklek says...

TomMmorRrow!, 9/10, will be etched in people's minds. We will then enter the completely changed post-9/10 world..
Let's pre-emptively create the Wikipedia article,
http://en.wikipedia.org/w/index.php?title=9/10&action=edit
before it's too late..

"The first attempt to circulate a beam through the entire LHC is scheduled for September 10, 2008, and the first high-energy collisions are planned to take place after the LHC is officially unveiled, on October 21, 2008."

^ CONCERNING STRANGELETS:

First of all, strangelets are merely hypothetical type of matter. None have so far been observed or produced. We would see some corrution of Neutron stars more often if the stuff was actual and not theoretical. Lambda particles I think have happened, but they decay so fast it is not really a subject of much fear mongering

Secondly, the RHIC (Relativistic Heavy Ion Collider) in the US has been working for 8 years now and no strangelets have been produced there. In comparison, LHC collisions will have more energy, thus making it even less probable a strangelet might form (equivalent would be ice forming in boiling water). In addition, LHC quarks will be even more dilute than at RHIC.

Read this study on RHIC by MIT, Yale and Princeton physicists to find out more.



"It is believed that the higher energy of the lead-lead collisions of the Large Hadron Collider (LHC), compared to the RHIC, will produce more strange quarks in the quark-gluon plasma (QGP) than are produced at RHIC's QGP. This higher production of strange quarks might allow for production of a strangelet at the LHC, and searches are planned for such upon commencement of collisions at the LHC ALICE detector."

"Angelis et al., "Model of Centauro and strangelet production in heavy ion collisions", Phys. Atom. Nucl. 67:396-405 (2004) arXiv:nucl-th/0301003 "

I thought that was an interesting read on the subject. It's all theoretical though, so far, we haven't really seen the stuff at all.

Sorry for the long gap between posts, the hurricane messed with my normal routine.

OMG THE HADRON COLLIDER IS TURNED ON!!!

So, there are many many people who believe that this collider will result in generating black holes that may destroy the earth.


I think the point of the worry is we are dealing the with same kinda forces that were around with the big bang...who knows what will happen, really. It is both exciting and scary, even more so when you think about the scale of this thing...that was only one small piece of the entire unit! That thing is huge! Like huge beyond the scale of any experiment mankind has ever attempted before.

I remember watching old footage of nuclear bomb tests out in the desert. They had troops all over the place right near ground zero. Nowadays, that would be unheard of because we know more about radioactive fall out and all the destruction they are capable of. But back then, it was an unknown factor. Same goes for this thing. They are taking all the precautions they can, but we are still dealing with something that mankind has never ever attempted on such a scale. I am actually glad its not next door to me

On the black hole note though, I think it has been shown that a black hole that would be generated by that thing would be so small that it would be of no consequence. That isn't know for sure obviously, and we all know the reputation that black holes have so I think peoples fears are semi justified.

even as these guys are preaching their interpretation of "rationality"... real scientists are discovering alternate dimensions and completely different concepts of reality.


I had an interesting conversation on Thursday with a post-grad student studying Theoretical Physics, and he pointed out to me that no physicist has "discovered" an alternate dimension yet. Even String Theory (or the blanket M Theory) is a misnomer. They aren't really "theories", they are hypotheses. The Large Hadron Collider will hopefully prove the hypothesis of alternate dimensions, but at this point they are only on paper.

And while they might be discovering "different concepts of reality" our reality remains the same, have you noticed? Reality is reality, and discovering that there might be a dimensional Brane right next to me, right this moment, with an alternate version of me, possibly typing this in German instead of English does not change our reality. We merely understand another level of its complex nature. The physics in every day life won't get turned on its head, we'll just be a little more enlightened to the nature of the cosmos.


>> ^MINK:
Real scientists don't know shit, they research in wonder. Only the egomaniac publicity whores preach their "final answer" with such glee. These guys were so obviously bullied in school.


I take a slight cringing response to this broad and sweeping generalization of scientists. Referring to the first sentence, of course. "Real" scientists know an untold amount of things. Be it confirmed theories or merely suspected hypothesis. You are correct, however, by stating they research in wonder, that much is obvious. Without that child-like sense of wonder, amazement, and questioning of our reality, scientists wouldn't discover anything.

Just don't assume in an absolute that every scientist's ideas are resting on the edge of a blade. We're pretty confident in a good majority of our discoveries about our Universe, and our reality. Evolution, Gravity, DNA, the "Big Bang" come to mind.

The nice part about real scientists, though, is that when shown evidence that truly falsifies one of their theories, they will abandon it and take on the new facts, evidence, and theory.

I've seen it on a daily basis. I have a cat.

In reply to this comment by bamdrew:
I'd never before seen a vertebrate animal's eyes adjust with attention and excitement so intensely. All the muscles throughout the cats body load up in preparation for the kill, including the eyes. As a biology and physiology buff I thought it was rather remarkable. Anyhow... I guess the large hadron collider should be pretty cool, too... eventually...


In reply to this comment by Obsidianfire:
I downvoted on your cat videos because the sift is already overflowing with them. It's clogging up the rest of the sift. This is Videosift not Videocat. I'm just tired of seeing it. It's an easy way to make a top 15 and I think that's sad when we have other videos on here talking about Large Hadron Colliders and studies about how and why we sleep. You know, intelligent things. I don't like that the videos that let people think aren't getting very many votes and the videos that dumb people down are getting a ton. It's my opinion, so I downvote. That's the point of downvoting. If it were out of spite, I'd be downvoting ALL videos wouldn't I? It's nothing against you, and I know how it feels to have your video downvoted, but I've just had enough of it. So I'm being less passive and more aggressive. I do have the right to do that here, that's the point of the sift. If people don't agree then so be it. But that's what I feel and I'm not going with the crowd here.

5 minutes of a cat sitting in a corner "wary?" No more damn cat videos!

^I respect people's different opinions and taste. But I think ObsidianFire is downvoting my recent cat videos just out of spite. You've got problems with cat videos being sifted here? Alright then, nothing I can do about that. But that's still YOUR problem.
If you didn't want to see cat videos, don't watch it. It's clearly labeled 'catsanddogs', thumbnail has cat images on it, and the title & tags clearly say the word 'CAT'. Why watch something you know you're not gonna enjoy and bitch about it later? Whose fault is that?

This hippie has a dream job, now he needs a haircut.


second that on the haircut. My instincts are to say this fella is a cutie.. but I keep wondering.. cheek implants?

In any case, why is everyone so worried about this collider experiment?

Maybe after they get that Large Hadron Collider built, they can finally find a way to make Zero Punctuation's videos play in Firefox.


d00d - turn off adblock and enjoy.

LOL, morally flexible combine fighter. LOL, exaggerate standing. BWA-HA-HA poplar trees. Actually in the past games I always wished you could just outrun the cops and chill - I was happy to see that. HAHAHA - drive geese.

HA HA - *woohoo is called out in the video itself. Excellent.

Ah, good times.

" All in all, he seemed to have liked it. "
- well, he did point out the unprecedented fact he'll keep playing after the review after all! -
As campion points, yeah, don't put too much thought into your response (see my above model example, <grin>) b/c Yahtzee doesn't care, and most of us are too busy giggling along with the bitching.

I absolutley LOVE the use of the Serbian national anthem.

> I loved Brian Cox in "Rob Roy" and his Hannibal Lecktor was very subtly portrayed and a lot scarier than the later one by Anthony Hopkins.


don't even get me started, dude. Adaptation? handpicked by McKee to play himself?

>> ^deathcow:
Any black hole we create in a laboratory will be so small that it evaporates in nanoseconds.


absolutely! unless we're wrong, of course. in which case, we'd never even realize it anyway. much better than if we had been equally wrong about the first nuclear detonation, and torching a hole in our atmosphere.
so, yeah. i'll take that bet. light 'em up.
