What is Digg?181 Comments
- algaeturd, on 07/30/2008, -31/+276These shout/spams are getting out of hand on Digg...all hosting a grip of canned comments:
"great submit!" "awesome read" "loved it!" "thanks for the shout!" "awesome story!"
***** this *****. If these comments are the best you can do, you're not adding to the discussion at all. Period. If you really like something, do you really feel the need to just type out, 'awesome?'
Really? Because I like all kinds of ***** and since I know I like it, I don't feel the need to advertise it. If I find something within the article that I think warrants discussion or if I have a question about a story or article or want to share some insight, etc. then I'll do THAT on the comments page.
And now look at that...you've caused me to waste valuable comment space pointing out how pointless your comments are.
Awesome. Bury me. I buried you all so it's only right.
For the occasion, I'll do the proper thing and sign my comment...... yours, algaeturd - TimOgg, on 07/30/2008, -3/+79totally agree
if you like it isn't that what the "Digg" button is for?? - samoan27, on 07/29/2008, -15/+74"a blackbody curve (the reason behind that name isn’t important here, but you can look it up if you care — just set your SafeSearch Filtering to "on". Trust me here)."
This article was perfect, I'm not sure if I learned more or laughed more. - daflo, on 07/30/2008, -0/+55Wow. A good science-for-the-layman article on digg... This is too rare to go unnoticed.
The article is well-written, not too technical, but yet scientifically interesting and accurate (for once). - ostracize, on 07/30/2008, -9/+59Great post! Loved it!
- BedPost, on 07/30/2008, -4/+31It's actually just a joke on all the color blind people. CB: "I hate that I can't see the green stars!" Rest of the world: *snicker*
- humanerror, on 07/30/2008, -6/+29So basically our sun is green. We just don't notice because of how our eyes work.
Freaky. - linzperc, on 07/30/2008, -1/+22No, No, this was a very successful attempt at a poor joke.
- Halsfield, on 07/30/2008, -2/+23nice article, good break from "woman faceplants while walking dogs" , etc.
i think a giant green ball would be kinda hellish looking and i wonder if you got a planet that was made mostly of copper or nickel or some other metal that burned green and it turned rogue and got sucked in by a star's gravity and pulled close enough to slowly burn it away, would we see something like a green star as it slowly pulled it into its massive burning furnace?
it wouldnt be a green star of course, they showed in the article that its impossible, even with tampering, but a giant green ball of fire would be breathtaking if captured on film/photo.
I'm pretty sure there are lots of green nebula/gas regions out there anyway, so even without a star green still gets a fair amount of the universe. - paradigm1220, on 07/30/2008, -1/+19What the hell dude.
- orangefly, on 07/30/2008, -2/+18awesome reply....
- MacEnvy, on 07/30/2008, -0/+16I tried it without SafeSearch on, and there wasn't anything NSFW. I can no longer trust him.
- paradigm1220, on 07/30/2008, -2/+17That got old a week ago.
- FallOutBoyTonto, on 07/30/2008, -1/+16that was my unsuccessful attempt at a poor joke
- catfish182, on 07/30/2008, -0/+14i was glad to see this was not some ***** about lucky charms cereal.
- Majhem, on 07/30/2008, -0/+12I'd say that's because the Green T-shirt is not emitting light, but rather reflecting the green wavelength.
- MacEnvy, on 07/30/2008, -0/+11Although it would be awesome if they did.
- ChocChunkOaties, on 07/30/2008, -0/+11Sometimes, when the sun sets over the sea you get to see a very faint green flash just as it dissapears on the horizon.
http://en.wikipedia.org/wiki/Green_flash - Stupidumb, on 07/30/2008, -6/+16I hate you so much.
- DiggasWAttitude, on 07/30/2008, -2/+12I dugg you up.
- davidlow, on 07/30/2008, -0/+9"Beta Librae is often described as greenish, the only greenish star visible to the naked eye"
-Wikipedia
http://en.wikipedia.org/wiki/Beta_Librae - itstomreally, on 07/30/2008, -7/+16Photoshopped.
- diggopolous, on 07/30/2008, -0/+9Too busy eating my blueberries to do that
- Pittance, on 07/30/2008, -0/+8I doubt it. With fireworks, they find a chemical that oxidizes at a particular color and use that. They dont create small hydrogen fusion explosions.
- samby, on 07/30/2008, -0/+8For burning copper you also need oxygen! Stars don't burn things with oxygen. They fuse hydrogen nuclei to generate energy.
- fx666, on 07/30/2008, -8/+16Here is a meaningful reply -- the explanation given in the article is incorrect, as a physicist I know that. Lord Rayleigh, who was a prominent scientist, gave the correct explanation -- the green light emitted by the stars gets absorbed in the upper levels of Earth's atmosphere, while the other colors pass it without noticeable absorption.
- jaschac, on 07/30/2008, -0/+8Some good replies already, but I wanted to add: When you're talking about infrared goggles specifically you're no longer talking about "real" colors. Those are false-color images designed to show relative heat - brighter the color = more heat.
- DeskFlyer, on 07/30/2008, -0/+7So...why do green stars never appear in the photos the Hubble returns?
- SpectralSounds, on 07/30/2008, -1/+8Fall Out Boy sucks.
- Laguna2, on 07/30/2008, -0/+7Stars are not "burning".
they get their energy from fusion. - Sultis, on 07/30/2008, -3/+10Awesome comment, I loved it!
- digitalArtform, on 07/30/2008, -0/+6A good article to teach photographers about the kelvin color scale and white balance issues. - and why there is no green in the camera raw image color temperature adjustments
- klitzbtc, on 07/30/2008, -0/+6This is ***** weird, I literally learned about this in class 2 hours ago.
- HueytheFreeman, on 07/30/2008, -2/+8Would digg again!
- Laguna2, on 07/30/2008, -0/+6Its because the green shirt is only reflecting the green light.
Not the red and blue parts of the spectrum. - desertDenizen, on 07/30/2008, -1/+7This would also explain why we see every color but green in sunsets. I had always assumed it was a property of our atmosphere (and somehow related to plants being green to absorb as much light as possible). I'm pretty stoked to finally learn the answer, that it's an artifact of human perception. So much for objective reality.
- RSS14, on 07/30/2008, -0/+5I have a question, the article stated that objects warmer than absolute zero emit shorter wavelengths. If that is the case, then how come humans are seen as red when using infrared goggles? Humans are warmer than absolute zero, but they emit infrared light . . . Also, the warmer an object gets, the more infrared light it emits, right? :S
Can someone enlighten me please? - drummer815, on 07/30/2008, -0/+5Does this have to do with why green fireworks are the most expensive fireworks?
- paradigm1220, on 07/30/2008, -1/+6Well technically everything known to man is above absolute zero. Absolute zero is when all motion stops at the atomic level. Our red color is merely just a convenient representation of infrared light because it is not visible. As wavelength increases, temperature increases, so yes a warmer object will emit a higher frequency of infrared light. Just look at the blackbody curves on the article - each line doesn't immediately drop off before and after the visible light range. They all emit a different intensity of infrared based on each respective curve.
- Fortuna, on 07/30/2008, -3/+8digger please
- whatsthatsmell, on 07/30/2008, -0/+5with SafeSearch off it took until page 10 just to find a swimsuit picture. page 15 has some scary stuff though
- Renton, on 07/30/2008, -0/+5That's pretty neat. How come when I see a green shirt, it doesn't appear as white?
- Pittance, on 07/30/2008, -0/+5No, that would never happen. You would not find a stable star with any large amount of copper in it. And it would certainly never fuse, or burn the copper. Iron is the largest element that is creatable in a star. If you had a star trying to fuse copper, or even into copper, it would produce a net loss of energy, so it wouldn't happen. If you somehow had a star with 40% (lets say) copper in it, then all the copper would sink to the core. The Hydrogen and helum in the shells around it would then try to fuse. But once the copper collected enough in the core, it would collapse and turn the star supernova. Probably creating a neutron star if it was big enough.
The only way to obtain any element larger than iron, is for it to be rapidly fused during a supernova explosion. - samby, on 07/30/2008, -0/+5What they are saying is that every object at a certain temperature emits a mix of short and long wavelengths, not just one wavelength (one exception is a laser). Now as you increase the temperature, you emit more and more of the shorter wavelengths (higher frequencies). But at the same time, you emit some of the longer wavelengths too. Just look at the graph.
So humans emit a lot of infared as well as radio waves as the previous poster said. Just put your hand one millimeter from your face; you can feel them. - buckygrad, on 07/30/2008, -0/+4I have always found it interesting that people get dugg down (rightfully so) for posting canned comments, yet people cut and paste portions of an article, which seems equally lame and unoriginal to me, often get dugg up.
- CenturionMonkey, on 07/30/2008, -1/+5Wow that was awesome. I didn't even realize that there were no green stars until now. I wanna read that follow-up article he promised to write talking about how there are stars that look green.
- semvhu, on 07/30/2008, -0/+3For the scientifically curious....
http://en.wikipedia.org/wiki/Black_body - ShadowMarth, on 07/30/2008, -2/+5Actually, there's a perfectly explainable scientific explanation for it.... A friend actually complained when the game Sins of a Solar Empire (which we were playing) had green stars, because he knew they didn't actually occur in nature. He was pleased to know when I busted out the map editor that the developers also had learned this, because there was an option to place a "random non-green star". Of course the color of the stars had no effect on gameplay, but it was still nifty.
- dullnation, on 07/30/2008, -3/+6It's not invalid, its plain redundant.
Anyone who cares so much about someone elses comment on digg getting buried, needs to get out of the house more. - dib2, on 07/30/2008, -1/+4I'm sending Stardock Games an email with this article linked. They need to get their science right.
