    Erm, did I read that right? Are they seriously considering doing the big bang experiment? Aren't they slightly worried about what happens in that mirco fraction of a second? 0_o

    Nope. ;-P

    Seriously, the media always misreports this - what we're doing is recreating conditions very, very soon AFTER the big bang i.e. huge temperatures. What we're not doing is creating another universe or anything like that. And when scientists say "we don't know what will happen" they mean within certain realms of possibility. We are 100% certain that we are not going to destroy the earth for ecample.

    When you say "we" you don't mean you are part of the team, do you?

    As you spend far too much time on here, and your post has a spelling mistake. That concerns me.

    You see my point?

    People get all concerned about the creating black holes thing - but they must think we've never done it before. Black holes have been created before.

    They don't just suddenly wink into existence the size of a penny and work their way up to eating an entire universe - they're really small and just die out really really quickly.

    I'm a grumpy bastard.

    I'm sure a swarm of killer bees didn't enter the realm of possibilities for the guy who made them.

    I have a time machine in my garage. It's a cardboard box with the words TIME MACHINE on it. I go in, go to sleep for a bit, then come out and its the FUTUUUUURE.

    ...or the new present, depending on how you look at it.

    By us? It's not my field but I really don't think so! Are you sure?

    Yeah, I've heard of tiny miniature black holes being created during particle collisions before, that wink out of existence within nanoseconds.

    Think they may be theoretical, but not sure - theory being that the rate of hawking radiation >> the rate at which the atomix black hole sucks up matter

    I seriously belive things like this are the reason we are seemingly alone in the galaxy, a self aware species like us are just to damn curious for our own good and end up blowing ourselfs up before growing enough to reach any other life that *might* be out there somewhere..

    A little reading on the Fermi Paradox might interest you.

    Yeah maybe the universe contains false clues to direct intelligent species to carry out experiments that actually end in their destruction. It would be a great way of stopping the universe from being over run with intelligent species and nips a species in the bud just at the right point.

    "The LHC is a machine of extreme hot and cold. When two beams of protons collide, they will generate temperatures more than 100 000 times hotter than the heart of the Sun, concentrated within a minuscule space. By contrast, the 'cryogenic distribution system', which circulates superfluid helium around the accelerator ring, keeps the LHC at a super cool temperature of -271.3°C (1.9 K) – even colder than outer space!"

    Woot!

    Does anyone know the knew blast off date? I know it has been put back a couple of time due to faulty equipment.

    So in 2 weeks, the world will end. Cheers.

    Forever peace touches on this subject if I recall correctly. Not as good as it's presentation of god in forever free though. XD

    Read some Alastair Reynolds.

    Read some [enter any scifi writer name here].

    :)

    Heh. A good point well made, Xerx3s. :)

    I meant that Reynolds' work has the whole 'Inhibitors' arc running through it. Hell, it's one of the central issues in his universe.

    Yeah I have read the Reynolds "Inhibitor" series and it is similar to the story in Mass effect but then Reynolds was also borrowing from other authors on the idea of the inhibitors.

    I have no idea who came up with the concept of controls on intelligent life first but its certainly been an idea that's been around for a long time.

    I really, really don't think you have. They're theorised to exist, and we think we might make some ... but AFAIK it's never been done before. 99.9999999% certain.

    So, out of curiosity, what practical applications are expected to come of this? I mean, for £5.1b or whatever has been spent on it, I'm hoping that we get something for our money.

    What are the theories on what is going to happen when "the switch is flicked"?

    Well, it works one of two ways. Either a) I've read something online that either claims to have made them, and having no real scientific background I have no basis to say "lawl, no you haven't" or b) my chronic deja vu is kicking in and you guys do create some mini-black holes and given I read about it after the event, I presume you don't suck Earth into the void.

    I'm not actually joking with b) by the way. I suffer, and I mean suffer as it disorients me when it happens, from deja vu that lasts anywhere up to 20 seconds and I can recall with picture perfect clarity, sounds as well, what I've been doing at the time. These are unique occasions too, not something that I do on a regular basis.

    I also have suffered from the form of deja vu tied to a place. I can't recall the name for it now, but it's the overwhelming sense that you have been in that place before but have no memory of it. Happened to me when I was in Lerwick, Shetland. Despite my family hailing from Orkney, I'd never been there and my mother didn't believe me when I told her. Meh.

    Anyway, enough thread derailing. I demand answers! :D

    Meaning of the Universe Theory of Everything type stuff isn't it?

    And 5.1 billion seems pretty cheap for a planet killing doomsday device :D

    Wait! Have CERN actually just turned the Earth into a prototype Death Star? 0_o
    When are they testing this "not a planet destroying giant laser weapon" i mean Collider?
