Black Hole may have been created in Lab

But no, it IS theoretically possible to create a black hole through particle acceleration, but the accelerators needed would be the size of a galaxy. (according to Brian Greene)

I thought the event horizon referred to the actual point on a black hole where things were not sucked in, not a method of referring to the radius of such.

The event horizon is the edge of the Schwarzschild radius.

No, black holes, like any other massive body, pull on things at infinite distance. The issue w/ black holes is that once you get close enough, the gravity is so great that even light cannot get out. The fact is, the gravitation of a black hole is the same as any other massive body...if you swapped the sun for a black hole of the same mass, we would continue to orbit as normally (although without the sun it ould get mighty cold).

The Schwarzschild Radius

Any mass can become a black hole if it collapses down to the Schwarzschild radius - but if a mass is over some critical value between 2 and 3 solar masses and has no fusion process to keep it from collapsing, then gravitational forces alone make the collapse to a black hole inevitable. Down past electron degeneracy, on past neutron degeneracy and then on past the Schwarzchild radius to collapse toward zero spatial extent - the singularity. The Schwarzschild radius (event horizon) just marks the radius of a sphere past which we can get no particles, no light, no information.

What would that be if it were put into a decimal

Working on it, I'll get back to you on that.

.0000000000000000000000001 if my calculations are correct.

(10*10^6*10^8*10^8)^-1

So... 1E-23 seconds = 10 septillionth of a second or 10 yocto-second

He is 4 years late almost.... the first artificial black holes were created at CERN in Switzerland on September 11, 2001, a couple hours before the news story I am sure you are all more familiar with from that day, so it didn't get much coverage. This was roughly when John Titor predicted they would do it, and the microsingularities are critical to his time machine. This is in fact covered in the March issue of Hustler, so you can claim you read it for the articles

Wow, nice memory! That just happens to be my birthday, and I remember seeing it online at CNN.com while I was reading about NYC.

Seriouslly tough, this is pretty cool. jsut imagine if you could use this to absorb neutrons is fission.....lets just brush the dust under the carpet

I wonder what kind of tool can measure with the resolution of 10 yocto-second. Something tells me that ain't no ordinary stop watch

Finally! A use for scientific notation.

That's gotta be the worst birthday to have ever. Well, next to christmas day.

nah..It's a Brietling that runs on Grey Goose, poured into the catatonic thinkamajig by Vincent Price's daughter...

It's not THAT bad... I mean, it's only the worst day in American history.

I know....kind of like the beginning of a bad joke where you tell everyone its your birthday and everyone starts crying...

There is a reason I never went into physics in that once I got past newtonian physics I realized I had absolutely no handle on what was going on as it had no 'common sense' notions to it (probably the Reason I'm a Civil Engineer). Anyway, what the hell happens to the singularity after it is produced, I wouldn't think it could just decay and disappear but that appears to be the case. If that is true what happens to the energy captured by the singularity? Is it removed from our universe or released in the decay of the singularity.

ill show em a black hole that wasnt made in a lab.... damn scientists going to kill us all!

so that's why all my stuff unexpectedly slid two inches to the right the other day.

thats called an erection

someone need to make a weapon outta that.

Bam!

I've read several articles on this, it's very interesting. It appears that it may have been a very small black hole, too small to be self sustaining so it essentially evaporated. This may be incorrect however, I think they're just trying to explain it in terms of a black hole.

Hopefully we can use this to build a ZPM so we can power up the Stargate enough to get back to Atlantis

LMAO. Seriously though, I almost guarantee you that the first interstellar war we fight will be ended when some planet or another is anhillated by a black hole bomb.

Nobody knows. Theories range from the matter being transferred to a mirror universe, to the matter reaching a maximum density, then exploding back out. It is impossible to tell at this point, because you cannot get information back out of a singularity.

This time in the history of the universe is extremely exciting. Just in this century alone, we have revolutionized the entire scope of our existence, mutiple times. I can't even imagine what will happen in my lifetime. I wish I was somehow involved with the research for some of this stuff... I doubt I have what it takes to be a PHD student in astro physics.

I don't think those guys knew what they got and try to use an unscientific term to alleviate their projection.

What they produced is best describe as quack science.

I feel so much smarter just reading this thread.

Seriously though, this is the only time ever that scientific notation has a use. And it's also pretty cool to read about the physics side of things.
