Janus Posted August 2, 2016 Share Posted August 2, 2016 No, Dark matter doesn't interact in the ways it would need to in order to form structures like planets, stars etc. Link to comment Share on other sites More sharing options...
Moontanman Posted August 2, 2016 Share Posted August 2, 2016 There are some other schools of thought on this, I have communicated with Foot about mirror matter and possible ways to detect it. https://www.technologyreview.com/s/418687/first-evidence-that-mirror-matter-may-fill-the-universe/ https://en.wikipedia.org/wiki/Mirror_matter I am kinda surprised to see mirror matter suggested as a solution to the dark matter problem. It would have to be at the weak interaction limitFoot first proposed. In my conversations with Foot he seemed to think it might be somewhat more interacting than what Dark Matter seemed to be.

Strange Posted August 2, 2016 Share Posted August 2, 2016 The trouble with that is the distribution of dark matter required does not match that of matter that can form stars, planets, etc. Link to comment Share on other sites More sharing options...
