You may have heard of the Large Hadron 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 tens of trillions degrees centigrade, which is more than 100,000 times hotter than the center of the sun. If you wanted to make a ball the size of a basketball with the energy density of that which is generated by a proton collision inside the LHC, you would need the entire energy output of the entire sun for over 20 million years.
