The Earth is a dynamic system—it has a fluid, mobile atmosphere and oceans, a continually changing distribution of ice, snow, and groundwater, a fluid core undergoing hydromagnetic motion, a mantle ...
The “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...
A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes far below reshape the planet's gravity field over millions of years.
Direct evidence for modified gravity at low acceleration from Gaia observations of wide binary stars
A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary ...
The Earth is a dynamic system constantly undergoing change. As the processes of change affect the Earth's topography—the heights of land, ice, and ocean surfaces—they also modify the distribution of ...
