You may have heard of the large hardon collider (LHC), but perhaps you don’t know much about it. It is a particle accelerator that sits in the Cern laboratory just west of Geneva, Switzerland. This device takes two beams (each containing about 300 trillion protons) and shoots them at one another.
The protons colliding can experience temperatures of ten of trillions degree centigrade, which more than 100,000 times hotter than the centre of the sun.
If you make a ball the size of a basketball, with the energy density of that which is generated by a proton collision in LHC, you would get the entire energy output of the sun for over 20 million years!
