Continuing our championing of gravity as a pull on space itself and not an attraction of mass for mass we now turn to the mystery of neutrinos changing from one type to another in the course of travel. This has similarities to the eventual change in the frequency of light
over astronomical distances. We venture to suggest that once again gravity is the cause.
Once again neutrinos react very rarely with anything they encounter but they are affected inevitably by the gravity of the star or object of their origin every inch of travel. Dark matter,Dark forces, Dark energy are imaginary ideas, we know gravity exists.
Occam’s razor is poised!
