The Challenge Erik Johansson Session S176 • Explore the fundamental processes and some of nature’s mysteries An intellectual and technical challenge Ecsite Lisbon, 1 June 2007
Mysteries – the intellectual challenge • Is the universe that we know of only a small part of reality? • What is the dark matter of the universe? • What is mass? • Why is there practically only matter in the universe – practically no antimatter? • How does the primordial quark soup in the very early universe behave? Ecsite Lisbon, 1 June 2007
The technological challenge • Build a 27 km particle accelerator that accelerates bunches of a hundred billions of protons to almost the speed of light and make them collide. • The detection challenge • The detectors exploring the particle collisions are huge precision instruments Ecsite Lisbon, 1 June 2007
The LHC - CERN’s new flagship The LHC….work in progress! Two beams, each containing trillions of protons, will race around the 27km ring in opposite directions travelling at 99,999999 % of the speed of light… Soon at CERN
A seven storey high and 45 m long precision instrument 1800 scientists from 35 countries

A Large Ion Collider Experiment at the LHC • By colliding heavy ions, it will be possible to fill a region of space with the densest and hottest matter ever produced. • The ALICE experiment will explore the universe as it was in the first few microseconds after its birth: a soup of quarks and gluons. • http://aliceinfo.cern.ch/Public Ecsite Lisbon, 1 June 2007
Revealing the secrets of nature.. • Explore the dark matter of the universe • The secrets of matter/antimatter • The process that generates mass • The processes in the early universe • … with some of the most complex devices ever constructed • … together with Science Centres.
