- Murdats, on 05/16/2008, -2/+18you lost the internet?
- carpeclunes, on 05/16/2008, -0/+16Here is a photo of a black hole:
See, it is not very interesting. - matx, on 05/16/2008, -0/+12The black holes that would be created by the LHC would be so small that they would disappear very quickly and not have enough energy to suck anything in. So no chance of destroying the world if one is to be spawned. It even explains this on the CERN website.
- marjo9, on 05/16/2008, -1/+12i took a photo of a black hole once but the light never came back...
- Dundasbro, on 05/16/2008, -1/+10A photo of a black hole...?
- TheThirdLevel, on 05/16/2008, -6/+14Take that, you ***** gravity whores.
- apmtt, on 05/16/2008, -0/+7No, none of the scientists working on the LHC have considered the possibility of a black hole appearing. But now, thanks to you, I will tell them to do so.
- burninthepyre, on 05/16/2008, -1/+7Quantum mechanics: When you can't figure it out, make something up.
- FarvaRadio, on 05/16/2008, -0/+6Lies!
Well ok, im just bitter over the loss of my massive porn collection. - Cglass, on 05/16/2008, -2/+8the data is still on the platters...
- stringerbell, on 05/16/2008, -0/+6You have to kill the evil robot first, before one can escape the black hole!
- netneutrality, on 05/16/2008, -0/+6Nope..... embarrassed to admit I didn't understand anything past the second paragraph of that article.
- inactive, on 05/16/2008, -1/+7w/ CRACK THANKS TO TEAM RESURRECTiON
- karmabandit, on 05/16/2008, -0/+6This is just *theoretical* work, based on an as-yet unproven model. I didn't read their article in Physical Review Letters, but since it is from Penn State, I would guess it is based on Loop Quantum Gravity ( http://en.wikipedia.org/wiki/Loop_quantum_gravity ). This is just one of many possible ways to combine quantum mechanics and gravity, as opposed to String Theory, or others. None of those possible models is widely accepted, nor has any real evidence to support it. So, when and if Loop Quantum Gravity gets some independent evidence, then let's celebrate our hairy black holes ( http://en.wikipedia.org/wiki/No_hair_theorem ).
- pizzas, on 05/16/2008, -0/+5Ahhhh i always wondered how to escape a 2 dimensional black hole
- solld3th, on 05/16/2008, -2/+7thats kinda gross dude
- mult1task, on 05/16/2008, -0/+3http://digg.com/tech_news/Digg_New_Comments_System ...
- Totz83, on 05/16/2008, -2/+5So.. Gutmann Method > Blackholes.... Duely noted
In other news, wtf happened the comments setup? I dont like change! - akaz, on 05/18/2008, -0/+3*****' THING SUCKS!!
- jpl7986, on 05/16/2008, -2/+5It's called Hawking Radiation, it was Hawking also who proposed it back in 1974
- inactive, on 05/16/2008, -0/+3when is LHC set to start running. i wonder if they will schedule it for dec 21 2012(mayan doomsday) just for kicks.
- ksgant, on 05/16/2008, -0/+3Let this be a lesson to you people with bad stuff on your hard drive....they can always get the information back off of it....even if you have a handy black hole to throw it into.
- TheUserFactor, on 05/16/2008, -1/+4Then tell me where my iPod shuffle is.
- AngryAngryBrian, on 05/16/2008, -0/+2So remember kids always do at least a three pass wipe before you sell your black holes on eBay.
- hauntedchippy, on 05/16/2008, -0/+2Yes but it was never proposed to solve the information problem back then. This is a recent development
- Marinium, on 05/16/2008, -0/+2Second paragraph huh? One paragraph more than me...... Look! something shiny! brb.
- LeRenard, on 05/16/2008, -0/+2Isn't Hawking Radiation when particles hit the event horizon and "reflect" as anti-particles?
- V1ncent, on 05/16/2008, -1/+3How to escape a black hole: Get Brittney to open her legs...
- trollick, on 05/16/2008, -0/+2"Once you consider quantum gravity"
Yeah.. ok.. and once you consider the implications of my new theory of magic, all kinds of things are possible. - awtripp, on 05/16/2008, -1/+3does this mean we can get back all those emails the white house deleted?
- wazzu07, on 05/16/2008, -0/+1it is...but they are theorizing that the energy or material isnt lost like physics says it shouldnt be. which i guess they should have just thought all along. now thats a thinker.
- smek2, on 05/17/2008, -0/+1"But the Penn State team suggest that singularities do not exist in the real world." -- wow, it took them this long to state the obvious? I mean, a singularity is after all nothing but a situation in which our (read, human invented) mathematical models break. That doesn't mean that there are actually singularities galloping through nature. If we encounter results which leading to singularities, we have to rework our mathematical models, not the other way around.
- rmxz, on 05/16/2008, -0/+1Momentum and kinetic energy seem to do what's needed.
If one black hole makes a near approach right next to another one it seems it's own momentum would carry it on past. - deadapostle, on 05/16/2008, -0/+1It seems to me as though the article is saying that if you get sucked into a black hole, you may be ejaculated in a fantastically different space time. I'm guessing you'd probably be physically reduced to a diamond by then, but that would be a neat way to travel through time and space.
- TheUserFactor, on 05/16/2008, -0/+1"Approximation of reality" is the key term. The human perceptions of distance and velocity and time really have almost no meaning in the context of the universe.
- yunus, on 05/16/2008, -3/+4Spoiler***
It's the same technique used in escaping from riptides. Swim sideways. - deadapostle, on 05/16/2008, -0/+1Let me just put on my special black hole moving gloves and I'll be right there to help.
I guess Douglas Adams might have gone this route. - rmxz, on 05/16/2008, -0/+1I always wondered if you could get stuff out of a black hole if you "simply" brought another black hole close enough and then pulled it away (or rather, let it's momentum carry it away) - and the gravity well of he second one will push "down" deep enough that some stuff from inside the first one can move halfway between the two, and as the second black hole leaves that matter could stay halfway between the two and get lifted out of the wells. Probably doesn't work in real physics (for some reason I don't understand), but might work in a scifi novel :).
- stix213, on 05/16/2008, -0/+1Is this supposed to be comforting, that the information of my fall into a black hole is actually preserved?
- benjorino, on 05/18/2008, -0/+1Its set to start running around mid-june this year, with the actual collisions being performed shortly after that.
- jks139, on 05/16/2008, -0/+1You sirs need a lesson in optics.
- MarkusX, on 05/22/2008, -0/+1Cool article about back holes.
I always wondered how information could be lost.
If it could, it has to somehow cross a barrier of no return, but I think it's always still there just infinitely smaller/farther away (in the black hole) yet not far enough to become invisible. - sparcher, on 05/17/2008, -0/+1Well, unless you and your coworkers are top notch physicists, I hardly think that is of any information to any of us here.
- ljmunz, on 05/16/2008, -0/+1Kinda like gravitational theory?
