The Large Hadron Collider is the largest scientific machine ever constructed. At 27km in cirumference, it will collide particles together at energies seen in the Universe less than a billionth of a second after the Big Bang. It's aim is to answer the biggest questions in modern particle physics, including the origin of mass in the Universe, the nature of Dark Matter and possibly even the reason for the incredible weakness of gravity.Next year we will switch on the biggest scientific experiment of all time. The Large Hadron Collider (LHC) at CERN in Geneva is 27km in circumference, and will collide particles together at energies seen less than a billion billion billion billionth of a second after the universe began. Its purpose is to answer some very simple questions: What is mass? Why is gravity so weak? Is our world really only 3- dimensional? Why is there any matter in the Universe at all? Using a paper clip, a fridge magnet and live filming of a bucket of snowballs, together with spectacular pictures of the construction of the LHC and it’s giant 7000 tonne particle detectors, Dr Brian Cox will introduce the fundamental building blocks of the universe as we know them atthe turn of the 21stcentury. He’ll explain why we need a machine capable of generating beams of particles thatwill comfortably fit inside the zero on a twenty pence piece and yet carry the energy of an aircraft carrier travelling at50 km per hour to investigate the smallest objects known, and how there might be entire new worlds less than a millimetre away from our heads,and yetwe are incapable of seeing them withoutthe aid of a 27km tunnel.Visit his website.
