A planet in motion: Understanding Earth’s changing gravity field B.C. (Bart) Root, Assistant Professor at Delft University of Technology explores how Earth’s gravity field is constantly changing and what these variations reveal about our planet. Everyone has experienced gravity, heard about the falling apple, and knows that gravity governs the motion of planets around our Sun. A static phenomenon that is always present, constant and not changing at all. You could not be further from the truth! Our Earth’s gravity field is full of regions with high and low gravitational attraction. Moreover, this field changes over time. Scientists use these characteristics to probe deep inside our home planet to reveal the inner workings of Earth.
