Scientists generally don’t like being asked silly questions, so when the guys from Sixty Symbols asked several scientists what would happen if you stuck your hand into the beam of the Large Hadron Collider, they were given pretty short shrift. Most of us would have simply left it there, however the Sixty Symbols guys are not most of us and so they travelled to CERN to ask the people behind the LHC what they thought would happen. Turns out that the CERN scientists were more than happy to chat about crazy theoreticals. I imagine that’s why they work at a giant super collider beneath Switzerland.
In case you’re wondering, putting your hand in the LHC would be a bad idea.
