fascinating - gravity math inaccurate,as shown by spacecraft



http://www.economist.com/science/displaystory.cfm?story_id=10804075

So-called "slingshot" maneuvers produce a tiny amount more speed than  
current known gravity models allow for... 4mm/sec... and the deep  
space and other probes that have used the maneuver have all seen the  
effect.

Unexplained little gravity phenomenon.  Very interesting.
