darkangel199 Posted September 21, 2006 Share Posted September 21, 2006 Baby Bang experiment could open door to new dimension Monday September 11, 2006 Deep underground on the Franco-Swiss border, someone will throw a switch next year to start one of the most ambitious experiments in history, probing the secrets of the universe and possibly finding new dimensions. The Large Hadron Collider - a 27km-long circular particle accelerator at the CERN experimental facility near Geneva, will smash protons into one another at unimaginable speeds trying to replicate in miniature the events of the Big Bang. "These beams will have the kinetic energy of an aircraft carrier slammed into the size of a zero on a 20p piece," Brian Cox of Manchester University told the annual meeting of the British Association for the Advancement of Science. "We are going to make mini Big Bangs. "There has never been such a jump in particle physics. It will go into an area that we don't really understand," he added. The fundamental goal of the massive machine is to answer the basic but crucial question of how matter was created at the birth of the universe. "We don't know what 95 per cent of the universe is made of - which is a bit embarrassing for a subject that claims to be fundamental," Dr Cox said. "There is dark matter. It is all over the place but we have no idea what it is." "There is also something called dark energy, and that is an even bigger question. "It makes up about 70 per cent of the energy in the universe, but again we have absolutely no idea what it is. "It is an incredibly exciting machine. It will be turned on next year and run for at least a decade and probably 20 years and the first results - if the machine behaves itself - should start coming out within a year," he added. If the theories are correct, the machine will create tiny black holes that evaporate and possibly even find particles that offer evidence that the three dimensions known to mankind are just a fraction of those that exist. "That would be an even bigger headline than the black holes. It could be that there is a whole new universe a millimetre away from our heads but at right-angles to the three dimensions that are here," Dr Cox said. "That would be a real paradigm shift - our relegation to a little sheet in a multi-dimensional universe. "That kind of thing is really profound and will capture the imagination that perhaps the origin of mass won't, although it should. "For the first time in many decades we have built a machine that exceeds our powers of prediction. "New processes are bound to be discovered. We are truly journeying into unknown territory." Dr Cox dismissed worries that by adventuring into the unknown and creating tiny black holes, the machine could even destroy the planet. "The probability is at the level of 10 to the minus 40," he said. MINI BANGS * Scientists aim to reproduce miniature versions of the so-called Big Bang, which is thought to have started the universe. * To do this they will smash protons together at huge speeds along a 27km tube known as a particle accelerator. * They hope to create tiny black holes or find extra dimensions in the universe. * They estimate the possibility of accidentally destroying the planet as extremely low. * The risk is calculated at about 10 to the minus 40 - a 1 in 10,000,000,000,000,000,000,000,000,000,000,000,000,000 chance. http://www.nzherald.co.nz/topic/story.cfm?c_id=325&objectid=10400645 a few questions, first one, is this really possible or are these guys full of it? second one, i thought black holes period suck in anything that crosses their horizon. if so, then how will we be able to stop them before they suck everything in or simply rip a hole in our planet? final question, would this create a naked singularity since we are making the black hole? Edit: if this proves ther are hgher dimensons, then will string theory be more widely accepted and regarded as fact? Link to comment Share on other sites More sharing options...
Severian Posted September 21, 2006 Share Posted September 21, 2006 a few questions, first one, is this really possible or are these guys full of it? It is possible. Although Cox is being a bit optimistic with results in a year. second one, i thought black holes period suck in anything that crosses their horizon. if so, then how will we be able to stop them before they suck everything in or simply rip a hole in our planet? They do, but these black holes would be so small they evapourate (via Hawking radiation) very quickly and don't have time to gobble anything. final question, would this create a naked singularity since we are making the black hole? I can't answer this question because no-one has a quantum theory of gravity. My gut feeling is that black holes aren't really singularities. Edit: if this proves ther are hgher dimensons, then will string theory be more widely accepted and regarded as fact? Not really - there are plenty of non-string ideas with extra dimensions. No-one will be accepting string theory as fact anytime soon. Link to comment Share on other sites More sharing options...
CanadaAotS Posted September 21, 2006 Share Posted September 21, 2006 "Singularities" arent blackholes... singularities are points in mathematical equations where the said equations stop making sense. Thats why blackholes and the big bang as 2 examples are seen as singularities... however a singularity is NOT a physical object of any kind, just a mathematical problem... People seem to confuse singularities with actually things alot Link to comment Share on other sites More sharing options...

People seem to confuse singularities with actually things alot see, i was always thought a singularity was where matter was crushed to a infinite density, where gravity is infinitely strong, and where spacetime has infinite curvature. i thought that was in the center of all black holes. So that's not an actual physical thing? its just what happens at the center of a black hole? Link to comment Share on other sites More sharing options...
JesuBungle Posted September 22, 2006 Share Posted September 22, 2006 So if they succeed, are there gonna be aliens coming into our dimension like in Half-Life? lol:eek: Link to comment Share on other sites More sharing options...
iglak Posted September 22, 2006 Share Posted September 22, 2006 So if they succeed, are there gonna be aliens coming into our dimension like in Half-Life? lol:eek: no, silly. it'll be like stargate Link to comment Share on other sites More sharing options...
CanadaAotS Posted September 23, 2006 Share Posted September 23, 2006 omg0dz its gonna be sci-fi war! *runs into his stargate and closes the iris behind him* lol... but yah, there is no such thing as infinite density, curvature, etc. thats what a mathematical singularity spits out. I like to think of the centre of a blackhole like a 1/0 in a math equation Link to comment Share on other sites More sharing options...
