Man, this is one of those situations where I think: "Damn its fun to be alive now (in this day and age)" when we are making all kinds of cool discoveries....
2005-11-06 04:44:50 PM  
Ok, cool. I still want my flying car dammit. Or sub ether teleportation device.
2005-11-06 04:53:02 PM  
Woot! These are indeed exciting times we are living in.

But remember the chinese curse.

"May you live in interesting times."
2005-11-06 04:56:48 PM  
Spiffy. Hopefully they don't blow us up in the process.

Also, you cannot "confirm" a scientific theory. You can only gather evidence for it.

*grumbles at science writers*

heathens! the universe is only 10,000 years old. your 'facts' have been planted to confuse you, and to weed out the non-believers

Towards me.

lol. were i to kneel to anyone, down would most certainly be the direction i'd have to look

The holy grail of physics - gravity waves - is within reach.

Did they give up on the Grand Unified Theory of Life, Gravity, the Universe, electroweak interactions, and Everything?

an unprecedented view of the birth of the universe 13.7 billion years ago.

Is this the experiment part of which is also in Louisiana, or a new one? I thought all near-term gravitational wave detectors were expected to detect only "nearby" (<~ 100 Mpc) astrophysical events.

BTW, in physics "gravitational waves" and "gravity waves" are quite different. I figured from context what the headline meant, but it's technically wrong. Gravity waves are a type of fluid motion driven by gravity. Gravitational waves are complex distortions of the space-time continuum.

As long as it doesn't contradict the Bible, I'm okay with it.
2005-11-06 05:25:33 PM  

New one. This one looks to the mid weight near by events.

It's actually pretty simple for such a prtty complex problem/concept. I caught the article on it somewhere last month with the technical aspects. I'll look and see if I can get the reference for ya, since I'm on the laptop now and the lookie see was at the desktop..
2005-11-06 05:34:26 PM  
If this discovery comes to pass, will I be able to lower the gravitational field around my bathroom scale?
2005-11-06 05:41:10 PM  
But can it store 10,000 songs?

This other relevant site was being built a few miles outside Baton Rouge while I was drinking my brains away as a junior at LSU:

I, for one, think the theory of Intelligent Falling deserves equal consideration.

Wow man, that's heavy!

Gravity, it's easier to detect than you think.
2005-11-06 07:05:28 PM

Weight has nothing to do with it.

Why is it when people read something really cool like this, they have to pull up all their intellectual might and start spouting bigotry? Shut up. Noone wants hear how Jesus, Ghandi &/or Mohammad kicked you in the proverbial jimmies when you were a kid. Save it for a Beavis & Butthead thread, where your incredibly insightful commentary is on par with the actual subject matter.
2005-11-06 07:10:55 PM  
We may not have a religious flamewar here, frontierpsychiatry, but EdgeRunner is going for a political one.
2005-11-06 07:10:56 PM  
But what about intelligent gravity?
2005-11-06 07:12:02 PM  
2005-11-06 07:15:39 PM  
ZAZ, actually, the facility they talk about is the twin to the one operating in Livingston, LA, part of the LIGO project. Ideally, they wrould all 3 work together to independantly confirm a detection. Actually, there is a fourth on in Italy, but the chances of having all 4 interferometers locked is pretty rare, at least right now.
2005-11-06 07:16:15 PM  
The ability to detect and read gravitational waves will give us as much extra information about the universe as being suddenly given the ability to hear.

holly crap!
2005-11-06 07:17:40 PM  
That is just poor science writing on the whole.
2005-11-06 07:18:08 PM  

That Onion article reminds me of the chick track where a student claims that the binding force of the atom is not gluons, but Jesus himself.
2005-11-06 07:18:36 PM  
I guess the question is, will they also be able to detect Bio-Gravity?
2005-11-06 07:18:46 PM  
thread jack:

what is up with that owl cliche that always says something like o'rly ? what does that mean?
2005-11-06 07:19:49 PM  
I assume its an attometer laser interfermoter. How do they control the backgrounds? I remember reading about LIGO and the LIGO people just said "feedback".

Sounds like the project I'm on (nEDM), it'll probably be the best measurement of zero to date.
2005-11-06 07:20:47 PM  
Intelligent Gravity, in essence, so I've heard, was one of the old explanations for why things fell in the olden days, back when people would forfiet their Sundays, Wednesdays, and coppers to old men in dresses in trade for comforting words...
2005-11-06 07:21:42 PM instrument so sensitive it can detect an object moving one million billionth of a millimetre.

That's 10^-18m, or one attometre, unless I'm off by an order of magnitude or three.

No, I don't know how much that is in thicknesses-of-a-human-hair.
2005-11-06 07:21:47 PM  
Can we fling things off the planet easier now?
2005-11-06 07:39:16 PM  
Unfortunately "poor science writing" is necessary in order to make the story accessible to the average doofus.

depmode98: what is up with that owl cliche that always says something like o'rly ? what does that mean?

It's from Don't... don't ask.

Forget human hair, that's something like .0000001 of one wavelength of visible light.
2005-11-06 07:42:24 PM  
Every science article on fark has to be bad science or poor science or pseudoscience. Never simply a description of something in term that may be acessible to non-PhDs.

xor_4200, there's a better one linked to that. Read the dinosaur one, about how dinosaurs are alive today, just as the Bible says.

ROTFL! *sniffs, wipes tear from eye* God bless Jack Chick.

That curse is actually a urban myth created by an American president (nixon, i think), the Chinese have never heard of it.

Forget human hair, that's something like .0000001 of one wavelength of visible light.

I have never understood how they can use light to measure a distance that is much smaller than (1) the wavelength of light, (2) the size of the electron cloud around an atom, (3) the distance that thermal fluctuation makes the electron cloud move while the light is zipping back and forth.
2005-11-06 07:55:10 PM  
I find it highly unlikely that this thing will succeed before LIGO if is succeeds at all as LIGO is generally considered to have a much much better chance. Given that LIGO hasnt been able to find anything yet, I would be quite surprised if they see anything any time soon.
2005-11-06 07:56:30 PM  
Wavelength of visible light 4 x 10^-7 m. 10^-18m is MUCH less..

uhm one billionth of a millimeter is 10^-12 meter, which is a picometer, which indeed is less than a wavelength of light but longer than that of gamma rays. The experiment is kind of neat but is still just another funding sinkhole.
2005-11-06 08:01:06 PM  
I wonder if the world realizes the gravity of this discovery.
2005-11-06 08:06:13 PM  
Any projects to find out what causes gravity? I would think that would be more important than detecting waves, since if we knew what made gravity, we could find a way to negate its effects...
2005-11-06 08:08:44 PM  
I read in another article that the scientists got Ladbrokes to open a book - 100 to 1 against detecting gravity waves before the year 2010. The odds quickly tumbled as the scientists started piling the cash on and now the book is closed. Sweet! Imagine having a couple of thousand on that! Make a major scientific breakthrough, get rich and skin a booky at the same time!
