What was thought to be interference in a German gravitational wave detector could turn out to be proof that reality is in some sense a hologram.
While this is a fascinating discovery in its self it is a perfect example of one the things that makes me love science (Yes, I love science).
Every so often in the world of physics there is a theorist wondering how to find proof of their new idea while someone performing an experiment designed to measure something completely different sits scratching their heads at a set of results that seem to make no sense. It happened with Einstein predicting the Brownian Motion that baffled Robert Brown and with the discovery of cosmic background radiation which researchers initially thought was due to their antenna having a fault until they found out about some scientists at Princeton theorising that just such a signal should be found.
So to sum up:
