Frankly, if more of the general populace was more scientifically literate (even in just the scientific method itself) we wouldn't have these problems.

I really disagree with this last part, (and the "self correcting" and consensus part) but agree with several of your other points--thank you for the thoughtful post.

I'm confident the global warming scam will be exposed in time, and look forward to that too. We just need to make sure we don't do something silly and pass laws on wholly unsubstantiated theories--I'm sure you would agree with this.

Science and Technology can be a dangerous mistress, and can be more trouble than it's worth. We got the atom bomb before we got atomic power. Some people use it to get in the way of real progress, and not to help people and build things. Not only is this intellectually irresponsible, it ain't right.

According to their calendar, December 21, 2012 is it. OR, they just ran out paper (or papyrus or whatever they wrote their stuff on).

yea but how the hell were they supposed to know that thats when it ended??? wheres the proof??? COLD HARD FACTS?!??!?

Keep in mind though that there not TRYING to make a black hole....that could just be one of the consequences.

Also the odds of it happen are 1 in 50 Million so its quite unlikely but still possible.

nathangdad, at the event horizon what happens is this, the gravitational force is greater than the acceleration equal to C, the speed of light. Thus, if anything crosses that point, it can't get back out. It's also stretched immensely due to tidal forces, torn up on a subatomic level and time in the local area stops. A black hole isn't like a whirlpool. It doesn't draw stuff in like that. It has gravity, same as any other object in the universe. If you get too close, you can fall in, but you have to get too close. They are perfectly safe as the correct distance, which isn't as far as many people think since again, gravity gets way weak over distance.

Our galaxy has a supermassive black hole in the center, it's not eating the galaxy. In fact, it seems to be cyclical. The x-ray jets caused by stuff falling in pushes other stuff away, once there's nothing to take in, it starts losing mass via Hawking radiation, once the jets stop, stuff can fall into the now-smaller hole again and the cycle continues. It seems to be part of how some galaxies properly form.

A black hole also doesn't have infinite mass, it has infinite density. We can calculate a hole's mass to an extent, or we can tell you the mass of a star that will eventually collapse into one. There's a certain threshold below which it can't maintain anymore, not enough mass. This is why micro black holes don't last, they're created by the energetic collisions producing incredible "compression" breaking down the normal states of a particle and, in crude terms, shoving the parts of it way closer than they should be. A proton, for instance, is made of quarks and a cloud of gluons. You cram the quarks too close together and the density ratchets up. Eventually, a critical threshold is crossed and the hole stops obeying purely Newtonian laws. But it needs to maintain that density...without enough original mass, it can't.

Most black holes are so large that the loss of energy/mass via Hawking radiation versus what they gain via background radiation is negligible, they'll last longer than we can predict into the future state of the universe, until the universe "cools" enough that there's less background radiation, but that's still being researched. But the little suckers?

Here's the math: Xaonon: Hawking Radiation Calculator

I put in 1 microgram, which is far, far larger than anything the LHC could create. The resultant hole would last for 8.407183e-44 seconds and have a surface area of 2.770613e-41 femtometers.

Way short and way small. Remember also that this will be happening inside as close to a true vacuum as we can make. There's nothing nearby to fall in anyway, it won't have time to cross any distance before it dissipates.

DaTeacha, as for the Superconducting Supercollider...

The LHC is 27 klicks around to the SSC's 87. The SSC could have reached 40 electron volts to the LHC's 14. In addition...well...the LHC is built to take advantage of the fact that the LEP (Large Electron-Positron Collider) was at CERN, too. They used the same tunnel. Saved a fortune. The LEP was in use until 2000, the SSC was cancelled in 1993.

Real shame too. This stuff will come in handy later. People wonder how. The basic theories of electrons were discovered through the mid to late 1800s. That comes in awfully handy now, doesn't it?

Thanks GlennM, Mayan. Not my area, I'm afraid. Not big on South American history.

No super-compactor for us, Deersniper. Unless you can get your trash in there really, really, really fast.

Ahh thats reassuring

I just couldn't resist...

No...actually they live in Central America.....Duh

Then we can hook up with some green lanky aliens and two headed dudes and visit Milliways the Restraunt at the end of the Universe. Where we all sit around and talk about viable guns.

Lol i'm with ya...Say 9:00 on Saturday?

[Packerfan2600]

So when is the worlds ending.....? lol
P.S. Sorry for my back to back to back to back to back to back posts

[tippmann7]

^^^^^^ wow just take over the whole thread lol jk

[larmus]

man i did not expect this thread to go past ten. wow.

The LHC is full of the awesome.

Also full of charged particles moving at relativistic speeds, but that's not important right now.

What is important is if something goes wrong, there's a guy there who can use that crowbar.

But really, everything will be fine.

Here, for the worriers, link to a live webcam of the LHC and facility at CERN:

nice...that is a scary resemblance to halflife

and a caption for the big pic:

"ive got the speaking wand, listen up everyone. now which way do we go?"

Omg it's GORDON FREEMAN!!!!! Were saved!!!


btw I still have nightmares about that cat........

damn i thought that was real at first!!!!!!

[Mad Hatter]

I have seen this thing in the news, I don't understand what it will do, but it scares me..If anyone finds out exactly what day it will be up to full speed let me know so that hopefully I can be at home. I don't want to be sucked into the black hole without my shtf gear..thanks

[billy]

it is yet another sign of the end times i tell ya
first cats sleeping with dogs
and now THIS!

[Deersniper]

I think a black hole has formed. It might located under Wall Street. It has already sucked in 600 billion dollars!

[Girlgun]

personally, I am ready for it. I think it is GREAT. I woke up this morning trying to figure out how to get rid of the bear that has been cleaning out my flock of chickens. Now I am thinking, say, maybe there are practical uses for mini black holes? especially temporary ones! Say I had a mini black home generator right next to my fridge in the kitchen. (that's next, right?) I could just eat up that old bear w/ a black hole. Or maybe the trash? We could send everything from bad bears to tumors off to some remote plane of nonexistance. Hell's bell's, I love physics!
BTW, Coeloptera, how'd you get so darned smart?!
