Particle Cascade By Dan Whiteley & Adam Esmail

Research

European Organisation for Nuclear Research Geneva, Switzerland known as CERN

Experiments at CERN Total Cost $6 Billion 10 Years to prepare Done in conditions at almost 300ºC 6500 scientists work on the experiments, representing 80 countries.

The Atom protons neutrons electrons

500 trillion in one of these Protons and Neutrons. This is the number of protons in one gram! Approx. 6 x 10 23

HadronsLeptons ‘ Heavy Particles’ ‘Light Particles’ protons neutrons electrons

Large Hadron Collider (LHC) ++ 1,000,000,000 km/h ! KABOOM!

The ‘Big Bang’

Time: 0 seconds Temperature: Infinite All forces were one Gravity Strong Nuclear

Time: 1 trillionth of a second Temperature: 1000 trillionºC Gravity Strong Nuclear ElectromagneticWeak Nuclear

Time: 1 millionth of a second Temperature: 100 trillionºC quarksleptons

Time: 1 thousandth of a second Temperature: 1 trillionºC Quarks make up hadrons

Time: after 100 seconds Temperature: 10 millionºC Helium nuclei form

Time: 100 thousand years Temperature: 10 thousandºC Atomic Era Hydrogen Atom: 1 proton, 1 electron

Time: 1 million years Temperature: 1000ºC Everything starts to cool down Stars and galaxies form

Time: 14 billion years (present day) Temperature: -270ºC Background Radiation

The LHC will help find out… … what happened during the Big Bang

PHYSICS IS SO MUCH MORE THAN THESE!
