gre Posted April 11, 2009 Share Posted April 11, 2009 What is the smallest object ever observed with gravity? Also, how is it determined/known that subatomic particles (ie free electrons) have gravity? Link to comment Share on other sites More sharing options...
ajb Posted April 11, 2009 Share Posted April 11, 2009 Gravity in the sub-millimetre scales has not been fully explored, let alone anything on the sub-atomic scale. There are experiments exploring gravity on the mm scale. Maybe someone else here can enlighten us. If not try a google search. Link to comment Share on other sites More sharing options...
