    Darn physicists want to blow up the earth!!!

    Source: http://www.latimes.com/news/la-sci-c...track=ntothtml

    So the lovely people at CERNhttp://public.web.cern.ch/Public/Welcome.html have built the world's largest and most powerful particle accelerator EVER. According to the LA Times, "[at] the peak, the hydrogen protons in the new collider will reach 99.9999991% of the speed of light. Each packet of protons will complete 11,245 laps around the collider every second and carry as much power as a speeding train" (emphasis added). Cool right? I mean, they could discover the Higg's particle! They could discover different dimensions! Neato! They will be unraveling the secrets of the universe! Will the answer really be 42?

    Oh. Wait.

    From the article:
    Critics think the collider could also spawn a black hole that will swallow Earth.

    That could be just an appetizer. Once the collider got going, according to the doomsday scenario, it could gobble up distant stars like a child popping Skittles...

    It's just as possible that the tiny black hole would be stable and start chewing up normal matter, he said.

    It could take years for it to become large enough to gobble up the Earth, but there's no evidence that can't happen, he said.

    His suit for a restraining order is to "preserve the status quo while the court considers the arguments. In this case, the status quo is Mother Earth being here," he said.

    Another nightmare possibility is that the collider could produce something called strange matter, a theoretical substance that some physicists think exists in the center of the remnants of collapsed stars.

    The pressure and temperature are so intense that the protons and electrons fuse into neutrons, then collapse into a mass of quarks.

    Theoretically, the tremendous gravity of strange matter would convert any ordinary matter it came in contact with.


    Holy cow.

    A black hole has to start out from a very large mass to be stable enough to survive its birth.

    Provided the proposed Hawking radiation exists, small black holes will disappear in a flash of energy as soon as they're born. They would not be able to grow.

    They were arguing that in the Atomic Energy Commission back in the 60's too - old news.

    Back in the 50s there were numerous articles in magazines like Popular Mechanics about how it was pretty likely that when we set off the first hydrogen bomb, it would ignite the atmosphere.

    In reality, black holes formed from that small a mass will evaporate in a very small fraction of a second.
    And as far as strangelet creation, particles with much higher energy than the LHC can create are impacting the atmosphere many times daily, and it hasn't destroyed the earth in the last 3 billion years. I think we're pretty safe.

    I heard that the guy who brought this suit is facing a court hearing on identity theft charges. He's a charletain and is just looking for publicity.

    Well, they just better not blow up France and Switzerland. What'll I do without all that lovely Gruyere cheese?

    Please tell me that the critics are from some religious group. It just has to be.
    “Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”

    You're putting entirely too much faith in nuclear physicists. Even they aren't really sure of their own theories.

    Utter BS. We've seen particle collisions happen naturally with as much as a million times as much energy as the most powerful collisions LHC will produce. These have been happening on a daily basis for more than likely billions of years.

    In other words, there's oodles of evidence that it can't happen. You don't even need to invoke Hawking Radiation to feel safe.

    But while we're on it, I once did some looked up a little info on possible characteristics of a black hole that might be formed by the LHC. I don't remember the exact numbers, but the mass ended up being equivalent to a few atoms, meaning it's gravitation pull is less than a speck of dust. It's diameter was roughly a millionth the size of a proton, so the gap between atoms in a "solid" would be billions of times greater than the black hole created. I don't even remotely remember its lifetime before evaporating completely due to Hawking radiation, but it probably made attoseconds seem like a long time.

    Holy criminy, that comes out to being about 6MPH (3 m/s) short of the speed of light. All they need to do is give the little bugger a running start, or a good, solid shove...

    (Also, I love that you can just type "c" into Google, and Google Calculator comes back with the number.)

    I want to blow up the earth too, to get to the creamy caramel center. I am going to do this, once I grow the worlds biggest apple.

    black holes do not explode...they just eat everything around them.

    oh, wait, that means there's already a bunch of black holes here in my office.

    The same concern was raised 'bout 15 years ago when the RHIC collider was planned at Brookhaven, with one goal being to study the quark-gluon plasma (cool phrase but I dunno what it is - I was just and engineer). As far as I know, it's run collisions at full energy, and no black holes yet!

    At CERN this week they started up the beams and gated them throughout the whole ring. They then have to gradually raise the energy (kinda like warm-up b4 a long ride?), maybe trying some small collisions. So far they probably haven't even seen much radiation, much less strange matter stuff.

    Only if you're pedalling toward the black hole.
