A model of geologic time is proposed, represented as a system of helical lines, and in each of them the radius of the cylindrical surface and the step are determined by the period of cyclicity. It is shown that the spiral structure of geologic time imposes natural limitations on the area of application of the actualism principle.
The interrelation of micro-, macro- and megarhythmics of the Universe is considered, conditioned by their correspondence to the genetic code of the Universe - a set of primordial rhythms unambiguously defined by the world constants.T he Universe, thus, has a resonance-interconnected rhythmic structure, a fragment of which is geological cyclicities. This allowed us to construct a single equation describing the occurrence of fundamental events in the history of the Universe, Galaxy and Earth. Comparison of the calculated dates with the dating of real events in the history of the Universe, Galaxy and Earth shows their good correspondence.
The physical causes responsible for low-frequency geological cycles (megacycles) with the duration of periods of 2 billion, 1 billion, 500 million, 350 million years and 176 million years are considered. The features of the solar orbit, the structure of the Galaxy, changes in the activity of the nucleus of the latter are analyzed, the consequence of which is a regular change in the physical environment within the solar system, which leads to contrasting events that are clearly recorded in the cometary annals of the Earth.
