the possibility of the mini blackholes (which is how the world MIGHT end) won't happen until around a month from now.  Right now test runs of the Large Hadrion Collider and udnerway sending particles one way on the machine and then the other way.  The scientists won't collide the particles for at least a month.  So, the world won't end today (obviously) but there's still a CHANCE (SMALL as it may be) in about a month.

Please note that the black holes that hopefully will be created by the collider are incredibly small.  You can turn anything into a black hole if you squeeze it down enough, but these tiny black holes will not "suck the world" into them.  Remember that all a black hole is, is just a very very dense object.  A star that becomes a black hole does not affect anything beyond its original radius effect of gravitation.  If our Sun were to turn into a black hole, we would not be sucked in because the Sun's mass would remain the same, therefore its gravitational pull on us would also remain the same.
The same would hold true for turning a subatomic particle into a black hole - it's mass is so small and the Chandrasekhar limit would be reached in such an unstable manner that it would have very little impact on its surroundings.

Here's the thing.  We can theorize what will happen should we create a mini black hole, but as we have never created one before it remains a theory and unless I'm mistaken at one point in time we all believed that the world was flat and were proven wrong.  Sure mini black holes probably won't destory the universe but **** it would suck if this were another care of the eath being flat.

Hmmm, but what if at the instant a microscopic black hole is created, it combined with the other black holes or particles around it and starts to grow exponentially?

So black holes are created based on density? Not overall mass? So they are basically created by the pressure placed on space. A large massive object will not create a black hole, while a small one of the same mass could. Okay, never mind, I'm starting to remember the things I learned about black holes lol.

As it is now wednesday we have all survived! HOORAY!

As i made this thread i thought i would provide some inf o to what actually happened.

(All info quoted from this site, all credit goes to those reporters)

http://news.nationalgeographic.com/news … ccess.html

The world's largest atom smasher's first experiment went off today without a hitch, paving the way toward the recreation of post-big bang conditions

The part that best sums up the experiment is here

By creating hundreds of thousands of head-on collisions each second, physicists hope to understand the fiery conditions of the universe a trillionth of a second after the big bang.

Here is also some very interesting infoormation about what they were studying.

The findings could also help resolve some of the biggest mysteries in physics, such as the existence of one long-hypothesized particle called the Higgs bosonâ€"or the "God particle"â€"thought to be responsible for giving all other particles their mass.

I think that its great that it actually worked. The physisits will release their findings soon no doubt.

Here is a quote from an article on the same site.
http://news.nationalgeographic.com/news … -hole.html

This and other harrowingâ€"and equally unlikelyâ€"scenarios prompted a couple of independent scientists to sue this past spring to stop the atom smasher. So far they haven't succeeded, and the vast majority of the world's physicists are on board with the project.

Im still thanking my lucky stars this didnt happen.

I don't think we need to theorize so much about black holes.  Their existence and lifespans are quite well understood and have been for some time.  Astronomers have gotten to observe Type II Supernovae as well as tons of other information from black holes during many stages of their existence.
As a side note, even the ancient Greeks knew the world was round.  It was just that people came up with mythical metaphors for the end of the explored world and the fears they had about going there.

I just worry that we shouldn't be so gun ho about doing things because we CAn do them, we should consider IF we should do them.  Maybe I've read The Andromeda Strain or books like it too many times, but I don't want to die because some scientisit idiot decided because he could **** up the wold he should.

Caution, that's all I want.

Ive taken a few Quantum mechanics classes and I think the things we will learn from this accelerator are great. I'm really excited to hear about the outcomes of many of the experiments that will be conducted.
