Geophysics is a research area focused on applying quantitative physical principles to investigate the structure, composition, and dynamic processes of the Earth and other planetary bodies. It integrates concepts from physics, mathematics, and computational science to analyze seismic waves, gravity and magnetic fields, electromagnetic properties, heat flow, and deformation. Geophysical research underpins understanding of plate tectonics, mantle convection, crustal structure, and core dynamics, and it enables imaging of the subsurface using methods such as seismology, potential-field analysis, and geoelectrics. The field also supports exploration geoscience, natural hazard assessment, and monitoring of anthropogenic and natural changes in the Earth system.
Climate change is lengthening our days because rising sea levels slow Earth's rotation. Researchers from the University of Vienna and ETH Zurich now show that the current increase in day length—1.33 milliseconds per century—is ...

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest beneath the frozen continent ...
