ABSTRACT
In this paper, we have presented a new approach to the dynamics of hypothetical primary particles, moving at speeds greater than the speed of light in a vacuum within their flat spacetime, which is why we understood the reason why they have not been detected so far. By introducing a new factor, we have linked the space-time coordinates of primary particles, within different inertial frames of reference. We have shown that transformations of coordinates for primary particles with respect to different inertial frames of reference, based on this factor, constitute the Lorentz transformations. Utilizing this factor, we have set the foundations of primary particle dynamics. The results obtained for the dynamic properties of these particles are in accordance with the fundamental laws of physics, and we expect them to be experimentally verifiable. Likewise, due to their dynamic properties, we have concluded that the Big Bang could have occurred during a mutual collision of the primary particles, with a sudden speed decrease of some of these particles to a speed slightly greater than the speed of light in a vacuum, which would release an enormous amount of energy. Created in such manner, our Universe would possess a limit on the maximum speed of energy-mass transfer, the speed of light in a vacuum, which we will show after introducing the dynamic properties of these particles. Similarly, we have concluded that the creation of other universes, possessing a different maximum speed of energy-mass transfer, occurred during the collision of these particles as well, only by means of deceleration of some of these particles to a speed slightly greater than the maximum speed of energy-mass transfer in that particular universe.
