- jewdiknight, on 07/17/2008, -2/+20Why does the hole always have to be Black?
- inactive, on 07/17/2008, -1/+15If measuring it's blackness, use the Wesley Snipes Scale...
If measuring it's actual weight, a scale of one to ten Oprahs. - TomFrost, on 07/17/2008, -0/+13Rosie O'Donnell.
- thebellmaster1x, on 07/17/2008, -1/+10Somehow, measuring things indirectly always turns out to be a lot cooler than doing it directly. It'd be kind of lame if we could just shoot on up and put the black hole on a balance. Analyzing the gases around it and extracting the mass from the resultant formulas is a lot more awesome.
- Elum, on 07/17/2008, -0/+9sucking implies suction.... it's not really sucking anything in... it's creating a deformation in the space time continuum which causes objects to move towards it.... there's no actual sucking involved at all...
- MoralThreat, on 07/17/2008, -4/+12I packed your mom's black hole with quite a bit of energy.
- Hello1024, on 07/17/2008, -0/+8"Sucking" isn't exactly a scientific term. It implies the movement of matter due to a pressure gradient towards the device doing the "sucking", which is not the case here.
- scalemodlgiant, on 07/17/2008, -0/+6I don't know, I think a balance capable of weighing a black hole would be pretty awesome itself. But what would we use as a counterweight...?
- ErrorBorn, on 07/17/2008, -0/+6Its whats on the inside that counts.
And, since we're talking about Black Holes that would probably be Hell. - inactive, on 07/17/2008, -1/+6That's not racist at all!
- Elum, on 07/17/2008, -0/+5everything has mass.... when you talk about weight on earth you are generally talking about the force that is created due to the gravity between the earth and an object... but it's all controlled by mass.... and density too.. but blah
- inactive, on 07/17/2008, -2/+7Racist article....right Commissioner Price?
- Murdats, on 07/17/2008, -0/+4probably because thats black, and space, is generally black.
- CrazyPirate, on 07/17/2008, -0/+4Well I don't have a PhD, but I can tell you that a phenomenon called "Hawking Radiation" means that not everything that goes into a black hole is stuck in there forever, they do actually emit some type of energy on some spectrum. I don't remember any of the specifics, but I just figured I'd throw it out there since you semi-asked.
- Elum, on 07/17/2008, -0/+3Heh... well it'd be great if we could get energy from black holes.... but... we can't even get to any black holes. They're too far away, which is actually a very good thing...
FEAR THE ROAMING BLACK HOLE!!! - GliTCH82, on 07/18/2008, -0/+3Is your joke-o-meter in disrepair? Don't worry, we'll take it off your hands and give you a new joke-o-meter absolutely free.
Joke-o-meter. Because being serious all the time is pretty ***** lame. - jimmypoops, on 07/17/2008, -1/+4It's called a black hole because it "sucks" in all the light in its vicinity thus making the area black.
Here's where someone with a PhD in physics comes along and tells me that my high school education version of why black holes are black was all rubbish... - MikeSetera, on 07/18/2008, -0/+3Weighing != massing
- TheInformer, on 07/18/2008, -0/+3Or Barack Obama's ears?
- Qrange, on 07/17/2008, -1/+3That's incredibly original. I am literally on the floor laughing my ass off right now. It's really hard to type.
- Murdats, on 07/17/2008, -0/+2oh no, we keep developing more precise methods? the horror.
should I mark your math answers as wrong because you only gave 2 decimal places when someone else gave 4? after all your less precise answer is obviously complete garbage. - kaosethema, on 07/25/2008, -0/+2true, thanks
- groo68, on 07/17/2008, -0/+2Why is sucks in quotes? isn't that what it does.
- youthinkicare, on 07/18/2008, -0/+2THAT'S RACIST!
- doublefelix, on 07/17/2008, -0/+2that's heavy, man
- magneteye, on 07/17/2008, -2/+3Once you go black you never go back?
- kinneas666, on 07/18/2008, -0/+1Even white holes would be black... figure that one out.
- Elum, on 07/17/2008, -0/+1Density is mass relative to volume (how much matter is packed together). When you measure temperature... I'm pretty sure... yeah... you're just measuring average kinetic energy... I just finished AP physics... ftl...
- Fritzel, on 07/18/2008, -0/+1The ultimate Rube Goldburg?
- Prismatic, on 07/17/2008, -2/+3lol
- mojoe1185, on 07/17/2008, -1/+2Why not just measure the diameter of the even horizon?
- inactive, on 07/17/2008, -2/+3how much of oil would be there
- FredFredrickson, on 07/17/2008, -1/+2You mean to tell me they don't just use a ginormous scale?
- rz8472, on 07/17/2008, -1/+2Taking my rudimentary knowledge of physics, that makes sense; the greater the mass of a black hole, the more the particles will be packed into a tighter space and the greater the average kinetic energy in a given area - an increase in the latter should generate more heat.
- cutright, on 07/18/2008, -0/+1OK... mr. doctorate. How about we just say there is a test particle of negligible (but not zero) mass just outside the blackhole. Wouldn't the blackhole have a weight compared to this test particle? Is it just me, or do they (doctorates and the like) do the exact same thing when measuring E&M fields?
- cutright, on 07/18/2008, -0/+1I don't quite understand the objection to the word weighing. Are you concerned that its a dangling participle and that they actually weighed it in the past? Or does it bother you that they're not using a physical balance? Maybe it's just me, but the act of assessing the weight of an object is called... weighing it.
- TheInformer, on 07/18/2008, -0/+1There are a lot of white holes on Digg.
- inactive, on 07/18/2008, -1/+2Affirmative action.
- y0urcl0ne, on 11/03/2008, -0/+1weight=0
mass=a whole lot - Fritzel, on 07/18/2008, -0/+1Technically Just below the event horizon they're anything but black, energy emitted from the star (the black hole or anything it might be feasting on is still giving off it's normal shade, however due to gravity that light emitted is either pulled back to the star or into a stable orbit (though I doubt you could call that chaos stable) around it.
Unfortunately we'll never be able to view this for ourselves, as assuming we actually could cross the event horizon and survive the gravitational stresses, imagine being hit with all the light that has been captured by the black hole (and the millions of stars like our sun) and kept in orbit for billions of years. It's just a _little bit_ hotter than a toaster oven. - Fritzel, on 07/18/2008, -0/+1The more mass the greater the pull and the smaller the horizon. But I think we'd have to have a peek inside to actually make accurate use of the information, and unfortunatly that's not possible see my post above
- kinneas666, on 07/18/2008, -0/+1I refuse to read the article because it talks about "weighing" a black hole.
- cutright, on 07/18/2008, -0/+1There's no technical about it. That's exactly what black means.... no color.
- kaosethema, on 07/18/2008, -0/+1black holes technically have no color since they suck up all the light.
- EmperorPsiblade, on 07/17/2008, -1/+1I suggest measuring them in metric LiveJournal Fatty Units.
- MEatRHIT, on 07/18/2008, -1/+1Dugg for "Supermassive Black Hole". Muse ftw
- inactive, on 07/17/2008, -2/+2Gas in a hole ? which one are you talking about ?
- kinneas666, on 07/18/2008, -1/+1there is no cubic inches at the center of a black hole, it's a singularity, it has no volume dimension...
