      As you might know, the Large Hadron Collider is a huge proton-proton accelerator and collider, consisting in a large ring 27km in diameter. At full speed, the proton beams travel around it about 11’000 times per second, meaning they are going at nearly 99.9999991% the speed of light!

      But that’s still quite a fair bit short (in terms of energy) of the “Oh My God!” particles (real name) that have been observed since the the 1990s: https://en.wikipedia.org/wiki/Oh-My-God_particle
