- robdiggity, on 10/12/2007, -1/+108Because you are a nerd and it's Thursday.
- NSMike, on 10/12/2007, -20/+99You know that Bush will turn this into a reason to go to war with Iran. This was already on Slashdot anyway. What the *****, ***** light can't move ***** *****, *****. Wait, what kind of pressure was it? God spoke the universe into being by saying "Let there be Light," surely he's responsible for this. Aww, screw it, he's not real anyway. In Soviet Russia, light pushes YOU! I, for one, welcome our new photonic overlords.

EDIT: Whoops, wrong place. Meant this for a reply down the page. - daedalus1982, on 10/12/2007, -11/+75now now gentlemen considering the statement wasn't:
1) a mispost
2) political in a non political post
3) asininely displaying a superiority complex in pointing out how he "saw this like totally last year on slashdot"
4) profane to the point of being discredited despite provided facts merely because he couldn't come up with more spots to fit the word "*****" in
5) asking a question answered in the first line of the post
6) a right-wing nut-job asking where God fits in
7) a left-wing nut-job responding by telling the right-wing where God can go fit himself
8) a comment about Soviet Russia
9) a comment about welcoming new overlords
10) ASCII art
i say we not digg him down
he has managed to post something on-par with everything else seen here today in the comments section... useless but nonetheless mostly harmless - sikosmurf, on 10/12/2007, -7/+70I think about 1.21 jiggawatts should do.
- moggygetro, on 10/12/2007, -1/+39Why did I suddenly think of lightsabers?
- WarpFox, on 10/12/2007, -12/+47@edz
now now, no need for foul language - chris9902, on 10/12/2007, -9/+41jigga please!
- datastorageguy, on 10/12/2007, -1/+30You just added one more congratulations
- edzieba, on 10/12/2007, -14/+38Percent sign dollar sign ampersand. And colon semicolon too!
- TheGentleman, on 10/12/2007, -25/+44@Junn168: I totally disagree
- DreKor, on 10/12/2007, -1/+19Investigative science isn't meant to return practical or applicable results. It is, instead, meant to discover how our world works. There's no way to know where a discovery like this will lead. It's dangerous to suggest that an avenue of study is worthless because no marketable discoveries are immediately present.
- toros, on 10/12/2007, -5/+22lol check that Moses***
- StacysMom, on 10/12/2007, -2/+19Great Scott!
- moggygetro, on 10/12/2007, -4/+20Why thank you! :)
- dooms13, on 10/12/2007, -0/+14For all disbelievers just remember that the photons, the particles of light, have momentum p=E/c, where p is momentum, E is energy and c is the speed of light. So it does need an incredible amount of energy to move an object.
- daedalus1982, on 10/12/2007, -4/+17@robdiggity
voted you for the quote of the day. shame this isn't irc chat or you'd have ended up on bash for that one - drewhenson, on 10/12/2007, -5/+18@cawpin
Light is massless. It is affected by gravity because space-time is warped by gravity, and light continues along its path in space-time, which, when warped, is curved.
For more information please see http://en.wikipedia.org/wiki/Photon . - MikeWeller, on 10/12/2007, -0/+11This is heavy.
- rstarr, on 10/12/2007, -4/+15Wait...Jigga what?
- inactive, on 10/12/2007, -8/+18Jigga who?
- Salgat, on 10/12/2007, -5/+14Up the laser to a few gigawatts and see what happens.
- Harabeck, on 10/12/2007, -2/+10Then I suggest reading the last part of the article...
- ThePikey, on 10/12/2007, -0/+8@waterdragon
"Some Movie?"
Nope, Dr. Evil is well known in the science community. He's done advanced research in the field of bio-engineered sharks and the grafting of lazers to their heads. It's been his greatest frustration to never successfully merged the two. However his son has made some advances and, while not a full graft of the lazer to the head, it is a functional merging of the two, such that the lazers will fire at the will of the shark.
The "number two" that is quoted was Dr. Evils right hand man who was often there to console the doctor when his plans fell short of his far reaching intentions. - casta, on 10/12/2007, -1/+8http://en.wikipedia.org/wiki/Radiation_pressure
- ThePikey, on 10/12/2007, -0/+7I wish more scientists would measure things using "Crazy Ass" as a spot on the chart. They could sprinkle in a few "Holy Crap"s and a "Freakin' Insane" too.
- drewhenson, on 10/12/2007, -1/+7Light has relativistic mass while moving, although it is incorrect to say that a proton has mass or invariant mass. See http://en.wikipedia.org/wiki/Relativistic_mass .
@Inet the "m" part is relativisitic mass. - kazersoza, on 10/12/2007, -6/+12Now .. just need the frek'n sharks!! ..
Cool story .. dugg.
thanks - PRlME, on 10/12/2007, -4/+10WarpDrive!
PS i never seen a science article with so much retard comments lol - DeskFlyer, on 10/12/2007, -2/+7Laser powered squirtgun fight! Pew! Pew!
- Zippo, on 10/12/2007, -2/+7She blinded me with science!
- Murdats, on 10/12/2007, -1/+6@drmangrum
ok, maybe this technology will be entirely pointless and will never be used, but what about the discoveries made based of this discovery, and the discoveries made based off those? somewhere down the line the brilliance that is future technology can trace part of it to this. just think if people said "pfft, discovering that lighnting will strike a key on a kite, how useless a discovery is that? why bother when it is so inheritinley useless (and it is, who wants to hit a key with lightning)" but the ramifications of the discovery are massive - drmangrum, on 10/12/2007, -1/+6high school physics > you.
- inactive, on 10/12/2007, -0/+5Also, a fart can create bubles in the water.
- PleaseJustDie, on 10/12/2007, -3/+7@cawpin
He's obviously making parody of the post above him, since he violates all 10 of the reasons daedalus gives to digg a person down. Mostly in order as well, 2-10 then 1 at the bottom. - DreKor, on 10/12/2007, -0/+4I agree that there are probably more efficient ways to move things, but that's not what they were looking for here. What they wanted to know was if it was possible for light to move something, specifically a fluid. As it turns out, it works!
- loquax, on 10/12/2007, -0/+3I can see the use in applying medicine in precise way into a very, very narrow place. I agree though, you are more likely to see a fart powered speed-boat than a light powered one... But then again, who knows? I could see a sub with no moving propellers with hundreds of thousands of "lasers" (note the quotes are done with my fingers) pushing it along.
- Klipart, on 10/12/2007, -2/+5I don't understand how it couldn't be the heat doing it, the laser they used to do that must of had some crazy ass power and with that power comes some crazy ass heat. Rapid thermal expansion of the liquid would cause an effect like that. I would like to see that photograph taken with an infrared camera.
- shinynew, on 10/12/2007, -0/+3With a very large boat? I'm not following you.
- cuoops, on 10/12/2007, -0/+3source - http://www-news.uchicago.edu/releases/07/070327.light.shtml
- sefert, on 10/12/2007, -0/+3You know I've heart of this before, I think it's called a Freaking LASER ! ! !
Dr. Evil: You know, I have one simple request. And that is to have sharks with frickin' laser beams attached to their heads! Now evidently my cycloptic colleague informs me that that cannot be done. Ah, would you remind me what I pay you people for, honestly? Throw me a bone here! What do we have?
Number Two: Sea Bass.
Dr. Evil: [pause] Right.
Number Two: They're mutated sea bass.
Dr. Evil: Are they ill tempered?
Number Two: Absolutely.
Dr. Evil: Oh well, that's a start. - Bdog2g2, on 10/12/2007, -0/+3and I assume you know the difference?
For ***** Sake: IT WAS A NEWS ARTICLE!!!! Would you expect the NYTimes to have a 4 page science journal excerpt detailing Quantum Entanglement? Or how about the Washington Post giving you all the equations needed for a shuttle launch? Or how about Neurology Now explaining the exact chemical processes that are involved when you determine that "Fake science is so immensely boring," - popltree2, on 10/12/2007, -0/+3Obviously it is soap. What else would it be?
- Modiga, on 10/12/2007, -2/+5Light doesn't have rest-mass, that's certainly true, but whilst it's moving it has energy. Surely E=mc² implies that whilst light is moving it does have some mass?
- dustysquareback, on 10/12/2007, -0/+2You are (probably incorrectly) assuming that the wavelength of light they are using interacts with the water mixture. If it is perfectly transparent to that particular frequency, then there will be no absorption / heat transfer.
Not really trying to flame here, but it kills me when Diggers second guess scientists that have problem been working in this field for YEARS. Like "Gee, we didn't think of THAT! Thanks Digg!" - TheInfamousOne, on 10/12/2007, -1/+3"You would be surprised how much energy is in a beam of light..."
Ok silly, but I loved K-PAX - zacwhite, on 10/12/2007, -2/+3Nope. The anti-matter confinement beam for the Enterprise was discovered today. Wow, I'm a nerd.
- popltree2, on 10/12/2007, -1/+2Oh god! I'm blind! Why would someone make a squirt gun that could blind you?!?
- logic, on 10/12/2007, -6/+7A big day in the history of soapy mixtures.
- jerryn, on 10/12/2007, -0/+1Also this article got me wanting one of these:
http://www.wickedlasers.com/catalog/Green_Lasers-3-1.html
But it will never come close to the 1,000,000 joule Yag Laser I had access to at my first job. we had a lens that focused the beam down to a micron.
bzzzzzzzzzzzzzzbang! We ionozed air and blew a hole through sheet metal. Fun stuff! -
