A cycle called the 27.5-million-year heartbeat, which has been happening on planet earth, has governed creation and destruction from the first event.

From primeval earth that is toxic to the blue water planet, it now bears the mark of change it has endured. The next shift could be around the corner, and the succession of events could mean life and death for fauna and flora.

Events on Earth Are Correlated, Not Random

In a period of 260 million years when animals as splendid as dinosaurs died out, the supercontinent Pangea shattered into what are continents and islands of modern-day, and humanity existed in the last few million years, reported Science Alert.

It is not random, but the earth has been constant and counting until the next event. This beat of the earth every 27 million years is unavoidable, like a doomsday clock.

These cyclic stages come an immense geologic time in a package of volcanic eruptions, extinction of species, tectonic re-arrangement, the raised sea levels. So far, it's the next 20 million years that everyone will live to see.

According to the lead author Michael Rampino, a New York University geologist, in a 2021 statement, these earth events in a cycle are correlated but not random but seen as spontaneous at first glance. The group analyzed about 89 well-understood geological events from the 27.5-million-year heartbeat of planet earth.

Eight of the events registered a cataclysmic change over a quicker time in these cycles; this would be the major catastrophic pulse that would be the deadliest phase.

Some of those times were tough, changing events clustering together over geologically small timespans, forming the catastrophic 'pulse.'

Earth's Pulse

A paper published by Science Direct said how the significant events had caused changes in the physical changes that include alterations of the magnetism of the globe. Everything was inextricably connected.

Geologists have suspected that a cycle existed for all geo-event from the earliest earth; in fact, a claim in the 20s to 30s by scientists says it was a 30-million-year cycle.

But in the 1980s and 90s, researchers have revised these pulses to come at 26.2 to 30.6 million years instead. It settled that the number of 27.5 million years is the right place to be. Another study by the same authors reveals it's the same time for mass extinction.

Alan Collins, a tectonic geologist from the University of Adelaide, said many of the events directly cause the other, leading to some of the 89 events being correlated.

Other researchers examined the earth's carbon cycle and plate tectonics in 2018 research and concluded that these cyclic pulses of tectonics and climate change might result from geophysical processes related to plate tectonics' dynamics mantle plumes, mentioned Science.

In the latest study, these 89 events are causal and happen in a succession of geological events, like anoxic events causing the extinction of marine species.

This pulse in a defined period exists, but how it leads to everything cannot be found out that easily. Some ideas are comets hitting the earth periodically, or Planet X said Space. The earth's heartbeat, recognized by research, shows planet earth is governed by cosmic influences associated with the earth's motions.
