Space pills #1 New

Did you know that planets don't move on perfect ellipses? Their perihelion, the closest point to the Sun, is in fact not a fixed point in space: after every orbit it moves a little. Newton computed such displacement but the numerical value did not match the actual observed one. This was particularly evident in Mercury's case: the difference between the theoretical value and the observed one was 43 arcseconds/century. Not until Einstein came up with the General Relativity Theory (1915), was such discrepancy solved. The new gravitation theory predicted a new effect which accounted for the mysterious difference in the precession of the perihelion which Newton already came across with. This was the first test proving the correctness of General Relativity.
