In 1755, Immanuel Kant had the remarkable insight that stars and planetary systems form by the gravitational collapse and rotational flattening of interstellar clouds. Later in the 18th century, Marquis Pierre Simon de Laplace refined Kant s idea by suggesting that planets condensed from rings produced at the edge of a contracting disk while the Sun formed at the center a picture thereafter known as the Nebular Hypothesis. ...
