This year’s Nobel Prize in Physics was shared between three scientists – Saul Perlmutter, Brian Schmidt and Adam Reiss – for discovering, through their research on supernovae, that the universe’s rate of expansion is accelerating.
Yet, as the plaudits for the winners began to flow, one or two of their peers sounded notes of caution. Martin Rees, former president of the Royal Society, suggested that this was an instance where the Nobel committee had been “damagingly constrained” by its convention of not honouring more than three individuals at one time.
The prize-winning work had been carried out by two groups, each made up of a dozen or so scientists. “It would have been fairer,” Rees argued, “and would send a less distorted message about how this kind of science is actually done, if the award had been made collectively to all members of the two groups.”
