Perhaps you could explain gravity to me. Start with one of:
A magical particle is created without any energy being consumed, that does not interact with matter, yet interacts with matter and travels at speed infinity telling super massive bodies to change their velocity without, again, consuming any energy...
A special super-invisible space-time fabric (not available at craft stores) holds all massive objects glued to it and it moves around, but there is no communication between objects, they are just reacting to a super awesome fabric that, again, doesn't communicate anything...
Unmeasurable waves permeate throughout the galaxy, containing no energy or mass yet lots of information and make super massive objects react to their presence by having both no mass and no energy, their literal non-existence makes planets and stars move...
