Vera Rubin did some interesting work observing and clasifying super nova I think and was first to grasp the opportunity of using them as standard candles (maybe I am dreaming it is all very hazy) and I think she made the comment that she did not feel comfortable with the suggestion that dark matter could be a particle we can never see and hoped for a more suitable answer
. It is annoying I cant recall the book or mag but there must be heaps of stuff out there as I have noticed her name in many locations, I recall she used a large refractor on a English Equatorial mount mmm I think
heck the harder I try the dimmer it gets
...forget the dark matter problems I need to address the grey matter problem
.
Anyways they are on the wrong track it is ""gravity rain"" they seek, if you can entertain ""gravity rain"" (gravity exsisting as the result of particle pressure acting as a pushing force not one of attraction) as a possibility it solves all those problems that dark matter and dark energy seek to explain...unfortunately I am the only person on the planet who understands how it does this
so it may be a little while before it is taught in school
