Earth’s inner core is not solid, it is 'shape-shifting' - time for textbooks to be rewritten
New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the vibrations generated by earthquakes that pass through the planet. The speed and the direction of the seismic vibrations change depending on the density and the elasticity of the rocks.
The Earth’s inner core is changing shape, study reveals
Scientists have discovered that the inner core's surface is changing shape, challenging previous assumptions about its solid nature
Earth’s Inner Core Is Changing Shape, Study Finds, Indicating Even More Dynamic Shifts Deep Within Our Planet
Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges
Earth’s Core Is Changing Shape
A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing hidden dynamics deep within Earth.
Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found that its edges are softer than realized and actually changing shape.
What lies at the center of the Earth? The answer keeps changing.
A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have questions, though.
