Are We Finally Walking the Planck?

There has been unease of late that physics is going nowhere. This is partly due to the fact that string theory and its later versions are not delivering anything tangible. Recently, Harry Cliff (Cambridge University and LHC of CERN) articulated these thoughts in the high energy physics community, when he spelt out at a TED Lecture in Geneva, 'the next few years may tell us whether we'll be able to continue to increase our understanding of nature or whether maybe, for the first time in the history of science, we could be facing questions that we cannot answer'. Cliff further says that this situation could be, 'Because the laws of physics forbid it'.
