The universe is filled-up with tiny, tight and vibrating energy packets which are packed in the black holes by absorbing the radiation emitting from the other universal objects. These vibrating energy packets are rushing towards low pressure ( of these energy packets ) areas. Nuclei of the atoms of the universal objects act as furnaces using these packets as fuel and radiate energy. This radiated energy get distributed using the vibrating energy packets as medium. Rushing of these energy packets cause gravity and planetary motion. solar energy is also due sudden burst of these packets, where at the Sun nuclei of atoms are kept open.
I think energy radiations, gravity and planetary motions can be interpreted by this notion. I never used to think that fruit from the tree is pulled towards the earth rather it is pushed.
