gravitational measurement

Gravitational measurement involves detecting the tiny forces exerted by Earth's gravity or other celestial bodies. Instruments like gravimeters measure how gravity varies across different locations, which can reveal underground features like mineral deposits, caves, or oil reserves. These measurements work by observing the slight changes in an instrument's position or oscillation caused by gravitational differences. Essentially, it's a precise way to map variations in gravity to learn about the Earth's subsurface structures without invasive digging, helping in fields like geology, resource exploration, and environmental monitoring.
