Ancient rocks show Earth’s magnetic field followed deep heat patterns inside the planet for hundreds of millions of years.
The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky ...
Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...
Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion ...
Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.
Scientists are mapping the Milky Way galaxy’s invisible magnetic field, revealing how it holds the galaxy together and ...
Physicists Reveal Hidden Geometry in Quantum Materials That Warps Electrons Like Gravity Bends Light
Essentially, the quantum metric creates a “geometric” drag on the electrons. When the magnetic field is applied, it breaks ...
