Today we talk of one of the most exciting things that is currently going on at CERN – which let’s face it is one of the most exciting places in the world right now. Once upon a time we accepted the world as having three dimensions of space and one as time and that suited us just fine – because we would see them and what makes more sense than seeing things?
Well the whole thing kicked off when Einstein worked out that gravity was nothing more than a wave in space and time. Fine. Then when a German mathematician turned his gaze to the electromagnetic force he realised that in order to adequately explain the force he needed a fourth dimension – and as if by magic out of these four dimensional equations popped the known forces of electromagnetism. This is a real whistle stop tour of breaking three dimensions – in fact we now think there are around 10 dimensions.
What I am talking about is the experiment at CERN which fills me with such great excitement. What they are doing is showing that these things actually exist. I am a theorist, but sometimes things being experimentally verified do really help. What these clever people are doing is accelerating particles really really fast (at the speed of light) and then they are colliding them into each other. When this collision occurs, what they hope to show is that there is less energy after the collision than there was before the collision – a violation of the fundamental laws of Physics? Well no fear not! This energy is being absorbed into the extra dimensions beyond the human eye.
There is a lot more to it than this; the press release can be found here. I do hope this experiment does what it sets out to do an that we get the proof we are looking for. It will be a great leap in the perception of the world if we can begin to accept the hidden dimensions, which will only lead us onto greater and greater understanding of the universe. Yes science.
