For the benefit of those not in the know, the Large Hadron Collider* is the world's largest particle accelerator, based in CERN, straddling 3 countries, funded by 60 countries and when it does its thing, it will either fill in the gaps in our present understanding of particle physics** or turn it completely upside down. The simple version, presented as rap, is as follows:
The physicists involved have every confidence that their experiments won't open up a black hole and obliterate this planet. Fine by me. LHC banzai!
* And you won't have been the first to say Large Hard-on Collider...
** You know, the bits even smaller than atoms.
