Recreating the Big Bang with the World’s Largest Machine – the LHC at CERN.
The 27km Large Hadron Collider (LHC), situated 150 metres under the Swiss-French boarder at CERN near Geneva, is the World’s most powerful particle accelerator.
Protons (hydrogen nuclei) are smashed together at 0.999999991 times the speed of light recreating, for a tiny instant, the violent particle collisions which would have existed less than a billionth of a second after the Big Bang. At the end of each year, lead nuclei are accelerated and collided in the LHC producing the highest temperatures and densities ever made in an experiment and recreating the exotic primordial soup which existed at the birth of our Universe.
Professor David Evans, from the University of Birmingham, will explain the physics behind the LHC, what we expect to learn and summarise the latest results. His talk will include some audience participation and demonstrations with niquid nitrogen and is aimed at all age groups.
7.30pm, Thursday 31st October 2013, Arts 120 Large Lecture Theatre. Hot drinks provided, followed by observing, weather permitting, and finishing in Joe’s. All are welcome.
