From Richard Davies
I really enjoyed your article on neutrinos and the questions they pose for particle physics (8 September, p 30), but surely the answer is obvious. We live in a 10-dimensional space; at the point where matter is created, antimatter forms in a slightly different dimensional arrangement. This shadow universe exerts a gravitational pull – we call it dark matter – while the antimatter-matter interaction produces dark energy. With tongue in cheek, problem solved.
