Elusive Dark Matter Could Be Detected with GPS Satellites

You know the old saying: “if you want to hide something, put it in plain sight?” Well, according to a new proposal by two professors of physics, this logic may be the reason why scientists have struggled for so long to find the mysterious mass that is believed to comprise 27% of the matter in the universe.

In short, these two physicists believe that dark matter can be found the same way the you can find the fastest route to work: by consulting the Global Positioning System.

A fair enough suggestion. There have already been searches for dark matter using the orbits of the outer planets, not finding anything. And there have been stringent tests on the theory of General Relativity using GPS satellites, again not finding any deviation from expected behaviour. But it doesn’t hurt to look.
