In Extended Classical Mechanics (ECM), mass is not a fixed substance. It is a dynamic quantity that changes when energy is released from gravitational or motional potential. Existence in the universe is distributed across different frequency bands rather than being confined to visible matter alone.
When a system converts stored potential energy into manifested energy, part of its material mass is reduced by what ECM calls Negative Apparent Mass (NAM). When this reduction becomes equal to the matter mass itself, the effective mass of the system becomes zero. At this point, matter does not continue moving as a particle — it transitions into a vacuum-mode state of the Phase Kernel.
This vacuum-mode is called f0.
This state does not mean “nothing exists.” It means the system no longer exists as matter. Instead, it exists as a pure energy-frequency state within the Phase Kernel. In this form it has no inertia, no gravitational mass, and no classical visibility — yet it still exists physically as a field excitation.
In ECM, ordinary matter occupies the lower, perceptible frequency band of existence. Dark matter and dark energy occupy a higher frequency band that lies above ordinary matter but below the Planck limit. They are not separate substances — they are the same underlying existence expressed in different frequency states.
Dark matter arises when matter is partially shifted into this higher-frequency vacuum-mode. Its mass is reduced and it becomes invisible, but it still interacts gravitationally with visible matter. Dark energy arises when this shift is complete, producing a fully vacuum-mode state that no longer attracts matter but instead generates a repulsive, anti-gravitational background.
Crucially, f0 is not just the beginning of the universe. It is not a historical moment. It is a physical state that can occur anywhere in space and at any time whenever matter is fully converted into Phase-Kernel excitation. The universe is continuously transforming matter into vacuum-mode energy and, under suitable conditions, back again.
This means vacuum is not empty.
Vacuum is the deepest energetic form of existence — the hidden frequency band of the universe.
ECM therefore connects gravity, motion, dark matter, and dark energy through a single physical process: matter transforming into higher-frequency vacuum-mode energy within the Phase Kernel.
This is not an addition to classical physics — it is what classical physics was missing.
