A Machian Approach to General Relativity
  Mach's principle is surely one of those tantalizingly beautiful concepts in
physics which remain elusive. Though General Relativity (GR) was conceived in
the spirit of realizing it, the theory failed to fulfill this expectation.
  Here a study on the implications of imposing Mach's principle on GR with an
insight that spacetime has no independent existence without a material
background, is presented. This inclusion of the principle in GR turns out to be
unexpectedly rewarding. The resulting theory solves many mysteries and averts
lingering problems of the conventional forms of GR and cosmology.
