In 1964 the theoretical physicist Peter Higgs, who has died aged 94, suggested that the universe contains an all-pervading essence that can be manifested in the form of particles. This idea inspired governments to spend billions to find what became known as Higgs bosons.
The so-called “Higgs mechanism” controls the rate of thermonuclear fusion that powers the sun, but for which this engine of the solar system would have expired long before evolution had time to work its miracles on earth. The structure of atoms and matter and, arguably, existence itself are all suspected to arise as a result of the mechanism, whose veracity was proved with the experimental discovery of the Higgs boson in 2012.
