    The works of Isaac Newton and Albert Einstein dominate the development of gravitational theory Newton’s classical theory of gravitational force held sway from his Principia, published in 1687, until Einstein’s work in the early 20th century
  • What Is a Gravitational Field and How Does It Work?
    A gravitational field is the region of space around any object with mass where other masses experience a pull toward it More precisely, it’s the force per unit mass at any given point in space Every object with mass generates one, from a grain of sand to a star, though only objects as massive as planets and moons produce fields strong enough to notice in everyday life How a Gravitational
