  1. As far as i am aware we have yet to observe a dark matter particle. Correct me if this is incorrect. Its certainly not through lack of trying however as lots of funding has been ploughed into this e.g CERN etc. Now i do have a basic understanding of why we are looking. My crude understanding is that the equations don't balance when we observe objects enormous distances away. For example other galaxies. As a result of these observations we know that there must be more mass somewhere for the maths to work, Einsteins equations to be more specific. In relation to gravity of course. Are we jumping to conclusions when we talk about dark matter? I find it difficult to comprehend a particle that doesn't interact with any of the known forces. I understand why we are looking but it just seems too far fetched to me. Could a more reasonable explanation not be due to black holes. We wouldn't be able to see them either, but could account for gravitational perculiarities we observe and gives us the mass we need to make the maths work. Has this been considered? Is dark matter 'pie in the sky?' Any feedback would be greatly appreciated.
  2. Dr. Jamie Farnes, a physicist at Oxford, has released a paper attempting to explain both Dark Matter and Dark Energy with a single substance producing negative gravitational attraction. Simulations of his model successfully accounted for the galaxy rotation problem that Dark Matter was introduced to account for, as well as the accelerating expansion of the Universe attributed to Dark Energy. Are there any major flaws with this model at present, either from observations or mathematics alone? How could such a model be verified or disproved? What would the implications be for the Standard Model? And, on the far edge of possibility: could this make an Alcubierre-style FTL drive workable?
