The most precise ever laser satellite measurement method provides new clues to relativity. Tides on Earth have a far-reaching influence, including disturbing satellites’ measurements by affecting their motion. This disturbance can be studied using a model for the gravitational potential of Earth, taking into account the fact that Earth’s shape is not spherical. The LAser RElativity Satellite (LARES), is the best ever relevant test particle to move in Earth’s gravitational field.

In a new study published in EPJ Plus, LARES proves its efficiency for high-precision probing of General Relativity and fundamental physics...
