Earth’s ‘Heart Beats’ Every 27.5 Million Years

In the last 260 million years, our planet has witnessed many great events. Dinosaurs came and went, the continents that were once a single piece of land called ‘pangea’ were divided into seven parts and took their present form, and with the entry of humans into the theater stage of life, the world quickly and irreversibly started to change.

And while the world is living all this ‘duration’ continued to hold. A recent study of ancient geological events has shown that our planet is slowly and steadily geological activity ‘heartbeat’He showed that he has it.

The ‘heart’ of the Earth beats every 27.5 million years

Representing these clustered geological events, including volcanic activity, mass extinctions, plate realignment, and sea-level rise, this heartbeat is an incredibly slow 27.5-million-year cycle of catastrophic tides and flows, according to a study published in Geoscience Frontiers. . So in other words this is the heartbeat in question every 27.5 million years is occurring.

In a statement he made in 2021, “Many geologists believe that geological events over time. random believes he is Michael Rampino, a geologist at New York University and lead author of the study, said: “However, our study provides statistical evidence for a common cycle, which means that these geological events interrelated It shows that it’s happening and not random.” saves as.

The team performed an analysis over the ages of 89 well-understood geological events that have occurred over the past 260 million years. According to the analysis, some of the times when such events occurred, as you can see in the graphic below, were more than eight world-changing events coming together in geologically small time periods. creating the ‘pulse’ of disaster was particularly difficult due to:

Among these events “Times of marine and non-marine extinctions, great oceanic anoxic events, continental flood-basalt eruptions, sea-level fluctuations, global intraplate magmatism pulses, and changes in seafloor spreading rates and plate restructurings”The research team stated that the “Our results, global geological events generally associated It shows that it is present and comes in pulses with an underlying ~27.5 million year cycle.” states as.

Cause of heartbeat unknown

On the other hand, another study published in 2020 and produced by the same research team shows that this 27.5 million-year period took place at the same time. times of great extinction events suggests it is.

However, it is unknown what causes the heartbeat of the Earth every 27.5 million years. While other research by Rampino and his team thinks that the cause may be comet impacts, a space researcher also suggested that the cause is in the Solar System, which has not been proven yet. 9th planet aka ‘Planet X’ claims to be.

But the research team also speculates that the reason may be closer to our planet than previously thought. In a statement on the subject, the team said that the heartbeat “These cyclical pulses of tectonics and climate change are related to plate tectonics and the dynamics of mantle plumes. geophysical processes results” may or alternatively “Related to Earth’s movements in the Solar System and Galaxy astronomical cycles by” notes that it can be accelerated.

When will the next ‘heartbeat’ be?

If we look at the calculations made according to experts, we have about ‘heartbeat’ in front of us for the chain of disasters mentioned. 20 million years is thought to be. Observing the previous ‘heartbeat’ in the graph they created was approximately 8 million years ago, the researchers point to a time far enough for us to take a deep breath for the next.

However, if we consider the disasters experienced today, from climate change to wars, from earthquakes to volcanic eruptions and wars, we can say that today’s people create their own ‘heartbeat’ with their own hands, even if there is no giant heartbeat.
