Abstract This article explores the physical properties of the intermolecular ether, which serves as the primary energy source of gravity and light. In the process of a solid body moving through liquids, its frontal surface compresses the ether within the intermolecular space, generating a gravitational repulsion force. Behind the trailing surface of the body, a cavern is formed—a zone of energetically rarefied ether (a vacuum zone). The sucking-in action of this cavern is known in physics as gravitational attraction. The most rarefied state of the ether within the cavern exhibits properties typically attributed to a "black hole." Under the action of these forces, liquid molecules are swirled into cavitation bubbles. Within these bubbles, the optical properties of the ether change: it loses transparency (forming an "ether fog") and generates a cold glow. This phenomenon renders the physical process of the emergence and propagation of gravity visible: The movement of molecules within the bubble generates a cold glow. However, the bubble itself remains stationary; thus, light is a quasi-motionless substance. A vortex (tornado) forms inside the bubble, generating the force of gravitational attraction. Under this force, the bubbles aggregate into a cluster. The permanent regeneration of bubbles within the cluster ensures the propagation of gravity at a speed of 300,000 km/s. The cluster serves as an analogue of the graviton, which is mistakenly referred to as a “photon”. In the process of generating the gravitational attraction force, the flow of time is altered, providing the theoretical basis for temporal displacement into both the past and the future.
