At the heart of our understanding of reality is physics, the cornerstone of science. But it appears to be in all sorts of trouble. For decades it has been predicted that we would find 'supersymmetry' - a set of parallel particles for all those we currently understand to exist. It was the solution to many inconsistencies and deep puzzles in our current theory - the minute size of atomic particles, the zero mass of the electron, and the nature of dark matter. Ten thousand scientists collaborated to build the Large Hadron Collider to find the evidence and its first results appeared in 2010. But year has followed year and no evidence of the predicted supersymmetry particles has been found.
Is supersymmetry dead and with it string theory, the theory of everything, and the life work of many leading particle physicists? Is the underlying theory, the Standard Model, fundamentally mistaken? Must we conclude that the whole framework of contemporary physics might be wrong? And if so, where do we look for an alternative?
