Thanks to gravity, we glide down snow-covered slopes on our skis, water flows from the mountains to the sea, and apples fall from trees.  According to legend, this phenomenon played a significant part when Isaac Newton developed the first mathematical description of universal gravitational attraction, realizing that the same force that makes those apples fall also choreographs the celestial ballet of planets, stars and galaxies. Without gravity, the moon would... Read more
