Although not a particle physicist I am fascinated by the news that CERN scientists have repeated their recent neutrino experiment and yet again confirmed that neutrinos seem to be travelling faster than light, despite theory saying this is impossible. This work may still be in error and the results may yet prove false. More tests are being carried out at other research centres over a longer timescale to see if the results hold up.
If true however, it raises all sorts of questions about the nature of space-time and our ability to move about in its many dimensions. Will we, one day, be able to look into the past and future? Maybe not in a way that allows us to interact, but simply look at who are ancestors were and our descendents will be.
Theories will have to be re-written and who knows where this will take us.
