Empty space is not empty…
Empty space actually houses virtual particles that shift in and out of existence constantly. This is merely the functionality of unmanifest reality, giving unmanifest potential the ability to reify into the manifest reality, which is the realm of matter.
Similarly we can liken this to ideas in our heads, for instance, a drummer hears a beat in his head (empty space housing virtual or unmanifest potential/latent realities), subsequently, he begins playing that very same beat on his drum set (manifesting the virtual or unmanifest content).
