From Perry Bebbington
Could it be that there is an anti-universe and that it existed, or exists, before our universe? It might explain where all the antimatter is (25 April, p 36). Perhaps the big bang created two universes: ours which goes forward in time, and an anti-universe going backwards in time.
Of course, from the perspective of the anti-universe, ours is the one made of antimatter and going backwards in time.
