Professor David Wark is the Chair of High Energy Physics at Imperial College, London. He explained the TDK experiment in detail for the Science and Technology Facilities Council, saying, ""People sometimes think that scientific discoveries are like light switches that click from 'off' to 'on', but in reality it goes from 'maybe' to 'probably' to 'almost certainly' as you get more data. Right now we are somewhere between 'probably' and 'almost certainly'."
