Earth’s 27.5-Million-Year Pulse: The Planet’s Mysterious Rhythmic Upheaval
Scientists have uncovered something astonishing: Earth seems to operate on a hidden clock.
Every 27.5 million years, our planet goes through a powerful geological reset — a "heartbeat" that triggers mass extinctions, giant volcanic eruptions, tectonic shifts, and dramatic sea-level changes.

In a study published in Geoscience Frontiers, researchers analyzed 89 major geological events over the past 260 million years. The result? These catastrophic moments don’t happen randomly — they occur in predictable clusters, spaced out like rhythmic pulses in deep time.

What Happens During These Pulses?
Global mass extinctions (land and sea)
Supervolcanic eruptions (like continental flood basalts)
Oxygen-starved oceans (anoxic events)
Rising or falling sea levels tied to climate shifts
Massive tectonic reorganizations

This isn't a brand-new theory — as early as the 1920s, scientists suspected a 30-million-year cycle. But now, with more data and advanced analysis, 27.5 million years has emerged as the most consistent interval.

It’s a stunning idea: that Earth’s most violent transformations follow a deep, cosmic rhythm — a geological metronome shaping life, death, and rebirth across eons.

Japan is building Dogen City — a revolutionary floating city designed to house 40,000 people while withstanding floods, tsunamis, and climate disasters. Built by startup N-Ark, this self-sufficient city is set to be completed by 2030 and could redefine how humanity lives with rising seas.

Its ring-shaped design includes renewable energy, vertical farming, smart medical care, and even an underwater data center. Most remarkably, it’s designed to float with the ocean current, absorbing shocks from natural disasters. Dogen City isn’t just science fiction—it’s a blueprint for the future of resilient living.

A coconut is more than a tropical snack—it’s a self-contained, ocean-proof survival vessel. Its tough, fibrous husk makes it buoyant and waterproof, allowing it to float for thousands of kilometers across salty seas without rotting or sprouting. This built-in durability helps it survive harsh ocean currents, storms, and long voyages between continents.

Even after drifting for over 100 days, a coconut can still germinate once it reaches the right tropical shore. With warmth, moisture, and a bit of sunlight, it can take root and grow into a full coconut palm. This amazing ability is how coconut palms colonized distant islands in the Pacific, Indian Ocean, and Caribbean—long before any human ever planted them. Nature crafted the perfect travel pod.

Scientists have uncovered a massive underground water reservoir located about 700 kilometers (430 miles) beneath Earth’s surface — a discovery so vast it could match or exceed the volume of all surface oceans combined. This hidden “6th ocean” isn’t in liquid form but is trapped inside a high-pressure mineral called ringwoodite, deep in the Earth’s mantle.

What’s even more groundbreaking is what this means for Earth's water origins. For decades, it was believed that most of our planet's water arrived via comet impacts. But this discovery flips the narrative — suggesting that a significant portion may have originated from deep within the Earth itself, slowly migrating upward. Using seismic wave data from over 500 earthquakes and 2,000 global monitoring stations, scientists found that these shockwaves slowed down as they passed through water-rich rock, confirming the oceanic-scale reservoir’s presence.
