Ocean tides are caused by the push and pull of the electrons in the atomic radiation chains. These electrons have expanded in size to the orbits of the sun and moon. They form virtual atoms with the sun and moon serving as their nuclei. An atom from the moon joins with an atom from Earth to form a pseudo Hydrogen atom that uses its ionization energy to push on Earth and the moon and sun. You cannot push on a rope, but you can push on the link of a chain.
