In collisions between nuclei at ultra-relativistic energies matter consisting of quarks and gluons can be produced at temperatures of over 1000 billion degrees (> 10^12K). T

This is the state that the universe was in when it was only 0.00001 seconds old.

With colleagues form the US and other European countries we operate  the BRAHMS experiment at  RHIC, USA., BRAHMS is one of the 4 experiments at RHIC.

Notable discoveries at RHIC is the phenomenon of high pt hadron suppression indicative of parton energy loss in a  color medium and  indications the Color Glass Condensate.

UNESCO is the organization within  the United Nations which deals with the intellectual side of human endeavour. in particular science.

A special focus of the Danish UNESCO effort is related to defining world wide ethical standards for science, promotion of higher education and research based education and working for peace and the betterment of human conditions through science and objective and critical assessment of facts.

We are now building the ‘ultimate’ nuclear collisions detector ALICE at CERN to study collisions between lead nuclei at 5500 GeV per nucleon pair: 30 times higher energy than now possible at RHIC.

The experiments are scheduled to start in 2007 using CERNs new 27 superconducting Large Hadron Collider.
