  I've got my Hawking radiation to keep me warmNov 25, 2010 7:11 AM PST | url
 
Added 2 new A* pages:Hey, where's the volume knob on this thing? Juuust kidding. I do like my dumb shows.
 
Tomorrow--or well, today I guess if you're up already :P--is Turkey Day in the US of A, but if I can shake myself out of whatever turkey and nog-induced coma I get myself into, I should be able to get at least one page up (which would be the last silent one in this little sequence, conveniently). And once Thanksgiving is done with, it's officially the holiday season and I can listen to Christmas music (it actually IS snowing again right now here in Seattle, which is pretty creepy...and hopefully it'll melt before I have to get my famous mashed potatoes over to mom & dad's place tomorrow...) without people thinking I'm too weird, yay!

Yesterday was another reminder for me to stick to the "if in doubt, add more black" rule I came up with for myself earlier in this episode; that rascally satellite just wasn't right until I gave it the super-dark shadow treatment (and then the limb of the planet, too):

Darker = better again, how about that.

Hm looking up Hawking radiation--a type of quantum radiation black holes in theory give off, giving them a very slight surface temperature--when I wrote the title of this news post landed me on a scientific paper from just a few months ago claiming to have verified the existence of Hawking radiation in a laboratory by shining "ultrashort laser pulse filaments" through a piece of fused silica glass that with the interesting property of having its refraction index changed when excited by the laser light: so in other words, the laser, traveling through the glass, causes the glass to become less and less transparent, causing the light to move slower and slower and eventually stop: a "so-called white hole event horizon." And then they measured some radiation coming out that they ruled out as having come from traditional means, and thus said it must be Hawking radiation.
 
That does sound maybe a little iffy, but it's interesting. Here's the scientific paper, and here's an article summarizing it in layman's terms.
