No, I read it elsewhere first.
It’s a joke about the recent superluminal (faster than light) result from the neutrino factory at Cern. Because if neutrinos did go faster than light, they might travel through time or break causality (things happening as a result of one another).
I have seen the Big Bang Theory though – and do quite like it! In a way I wish they’d have more stuff set in the lab (those are my favourite bits), and less lounging around their flat.
