Recently, two scientists have proposed a new way of detecting dark matter, using GPS Satellites. A part of the article is posted online: Hunting for topological dark matter with atomic clocks.

Can anyone make the it more explicit? How exactly could GPS Satellites detect dark matter?

  • $\begingroup$ I don't have full access right now (not on campus), but the abstract & images suggest that a gradient in dark matter content would result in a measurable time lag between two atomic clocks. $\endgroup$ – Kyle Kanos Nov 22 '14 at 1:21

    $\begingroup$ I have to say that this question would be a lot better if you (1) exhibited the abstract here and (2) said a little bit about what you found clear and unclear in the abstract. $\endgroup$ – dmckee Nov 22 '14 at 4:44
  • $\begingroup$ You're right but to be honest am all confused so :Can you just explain how could GPS satellites detect dark matter? Keep it simple. $\endgroup$ – George Smyridis Nov 22 '14 at 5:37
