The fundamental equation of the physics theory of time travel and cosmology

Marek-Lars Kruusen's time travel physics theory and technology is extremely voluminous, containing a lot of details. This paper presents only a small part of this theory. Since this is the third part of the series, the following parts will present more comprehensive and detailed reviews of the physics of time travel. This paper describes the physical nature of wormholes and its relation to the physics of time travel. The physics of time travel is actually much more voluminous and detailed than it appears in this work. It is important to understand that time travel is enabled by the physical system of hyperspace and normal space, which manifests in reality as the cosmological expansion of the universe. The mathematical parameters of a tunnel in spacetime, or wormhole, such as length and direction, follow from the above. The physics theory of time travel shows very strongly that the universe must be expanding at a constant speed of light c, but as we know, it doesn't look like that. Therefore, time must have slowed down throughout the universe, which is speeding up over time. As a result, the rate of expansion of the universe increases over time, which we know in cosmology as the concept of "dark energy".
