Lab Assignment 5: Mercury's Perihelion Precession and General Relativity According to Wikipedia, general relativity "is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics." In this lab assignment, a student completes a Python program to test with data an accurate prediction of Einstein's theory, namely the perihelion precession of Mercury. Mercury's orbit around the Sun is not a stationary ellipse, as Newton's theory predicts when there are no other bodies. With Einstein's theory, the relative angle of Mercury's perihelion (position nearest the Sun) varies by about 575.31 arcseconds
