Dark matter, hmmm..... Always be careful of 'stuff' that physicists create to make their equations balance, they have a strong motivation to 'make it work'.
If you like Brian Cox, find his series where he leads you to the conclusion that space and time are not fundamental properties of existance. My best guess is that we live in a derivative universe - or a derivative of the Universe - maybe like Sheldon's 'very sexy line segment' in Flatland
If you're interested in dark matter and are piqued by the relationship between science and philosophy, then I give you my personal guarantee Scott that you will consider the 20 minutes required to watch the interview below with Bjorn Ekeberg a worthwhile investment. It tempted me to invest study time in it.
