The "least unknowns" approach suggests that GR - observed to be correct in all situations where it can be measured - is correct, and dark matter is a form of matter (or at least a source of gravity) that we can't detect. Or (like the neutrino) that we can't detect yet. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
