Last year, you reported that dark matter might consist of both dark hydrogen and dark photons, rather than being a single thing (7 January 2012, p 30). Recent articles suggest that it may be far more complex (13 April, p 8 and 20 April, p 10).
Surely then, assuming dark energy to be a single phenomenon is flawed. If electromagnetism, the strong and weak forces and gravity make up only 15 per cent of the energy that current theories insist should exist, what is the logic in thinking the rest is a single force?
I like the idea of dark photons, but if it turns out that their paths are affected by dark gravity perhaps the 20th-century thinker who understood the universe best wasn't Wolfgang Pauli, Enrico Fermi or Einstein, but that master of things both dark and cosmic – sci-fi author H. P. Lovecraft.
