Hi there sanjone! Welcome to the forum. We actually had a recent discussion about this so perhaps you'll find it helpful: https://www.physicsforums.com/showthread.php?t=697284&highlight=mach's+principle You'll notice from the discussion that Mach's principle isn't even defined in an unambiguous, consistent manner amongst various texts mainly because it cannot really be stated in purely mathematical terms (it's usually thought of as a philosophical statement).
