From Paul Ellis
Perry Bebbington’s idea of an antimatter universe, receding in time from the big bang (6 June, p 27) goes back at least to J. Richard Gott’s 1974 paper in The Astrophysical Journal (vol 187, p 1).
More recently, John Gribbin ascribed the idea to Victor Stenger while reviewing his book The Comprehensible Cosmos (Times Higher Education, London, 13 April 2007).
