    These collisions are happening all the time, this is just the first we've controlled and can analyse.

    There isn't going to be black hole.

    Yeah, but not 600 million per second in a tiny spot on the earth. End of the world, here I come!

    The big bang sounds like a joke anyway if you ask me. It's something scientist came up with because they have no other explanation.

    lol, some really interesting ideas on this thread.

    I heard that the chance of the experiment causing a black hole is 150,000,000 to 1. Although there is soooo much made up crap being churned out all over the world about this I couldn’t say how reliable it is.
    If it is reliable though, a fair bet on the end of the world would be "If the world ends, I will give you $150,000,000 and if it doesn’t you have to give me $1." lol

    Steven Hawking said that these collisions happen all the time in the earth’s atmosphere, this experiment is just setting up the collision, so it can be observed.

    Fascinating though that the result of this experiment should determine whether many quantum physics theories are correct.

    Thats why the LHC was made to answer these questions, very exciting stuff. But what gets me is this, books that have been written before to answer these questions will either be wrong or correct. Many recent events in space have proven scientists wrong and had to do a rethink on how things work.

    I hope the world does not end as I'm just about starting to make some money from one of my websites

    Now they want to rename the LHC as they think it's probberly not the best name for it, so they are offering a £500 (about $1k) prize: link

    What other name can you come up with?

    AVLOR = A Very Large 'O' Ring

    I think you should start a new thread about this, it could be quite a fun/interesting thread.

    They have so much evidence. In fact, it's very unlikely that it didn't happen.

    Firstly, galaxies are moving away from each other (shown by the Red Shift) - this hints towards there once being a center point. Take into account that large things should move towards each other and not apart, you need some MASSIVE forces to do that for 13.7 billion years

    Secondly, the outer-space telescopes we have have immense capabilities. Remember that light has speed, it's not instant. We see the sun as it was 8 minutes ago, so if we look further we can see further back. They can see the effects of the big bang on some areas because they are so far away. Obviously we can't actually see the big bang because that would imply that we are traveling faster than the speed of light, but we can see back enough.

    Definately, scientists dont just make things up, that defies the whole point of science. Every theory has some kind of evidence behind it, a scientist will say "I think.... Because....(evidence suporting previous statement)" or "I dont know".

    when you hear someone say something like
    The big bang sounds like a joke anyway if you ask me. It's something scientist came up with because they have no other explanation.
    Its almost always because they either havent done any reasearch themselves into it, or they dont understand it themselves so dismiss it. Its like people who say evolution never happened and then give some lame excuse like "because we dont look like chimps and eat bananas", they just dont understand the very solid evidence behind it, and dont want to know it either.

    Or as Rudy would think of it
    Code sql:
    SELECT Theory FROM Science WHERE ID NOT IN(SELECT DISTINCT ScienceID FROM Evidence)
    0 rows returned

    (Excuse my terrible SQL)

    See, SQL saves the day

    Just found out that the competition ends today, drat and double drat

    Maybe I'll consider making a new thread naming the LHC.

    That's what we think now. But we may find somewhere in the future another Copernico, or Isaac Newton, or Einstein that will change everything we know until now and the way we understand things.

    LHC has been halted for about two months due to a magnet failure.

    A snipet from the bbc's website:

    On Friday, a failure, known as a quench, caused around 100 of the LHC's super-cooled magnets to heat up by as much as 100C.
    The fire brigade were called out after a tonne of liquid helium leaked into the tunnel at Cern, near Geneva.

    Could this be the beginning of a black hole?

    The power involved is pretty amazing...

    Quote Originally Posted by http://www.symmetrymagazine.org/cms/?pid=1000570
    While a beam of particles by itself creates very little heat, beam particles straying from the core of the beam will heat up surrounding material. It takes just a small number of beam particles hitting a magnet in one spot to raise the magnet’s temperature above a critical point, causing it to suddenly change from superconducting to “normal” conducting. This change, called a quench, releases the stored energy of the magnet and its neighbors; it can heat a small part of the magnet from -271 to 700&#176;C (-456 to 1300&#176;F) in less than one second.

    “If we don’t do anything, all the stored energy will go into one magnet, and that magnet will be destroyed,” says CERN’s Rudiger Schmidt, coordinator of LHC machine protection. “We have to detect a quench and take action to put the energy somewhere that it’s not dangerous.”

    When a quench begins, the beams are shut down and power to the affected magnet is immediately cut. Then heaters fire up, quickly raising the temperature of the whole 14.3-meter-long, 35-ton magnet and dissipating the energy.

    Each dipole magnet is connected to 153 neighbors, and their energy also has to be immediately removed. A switch sends the energy into large resistors, where it heats eight tons of steel to a temperature of 300&#176;C (570&#176;F) in less than two minutes.
