Pierre-Simon De Laplace (b. 1749, d. 1827) was a Icons-flag-fr.png French mathematician who developed the nebulae hypothesis - the idea, originally proposed by Icons-flag-de.png German philosopher Immanuel Kant, that the Solar System originated from the contraction of a huge gaseous nebula. Today, the hypothesis provides the most widely accepted theory on how the Solar System had formed. Another of Laplace's contributions to science was to analyse the complex forces of gravitational attraction between the planets. He investigated how these might affect the stability of the Solar System and concluded that the Solar System is truly stable.
