14 pictures that can make you doubt the law of gravity and physics

On a larger scale, gravity arranges cosmic bodies into orbits and even causes drifting space particles to pull together slowly into larger and larger clumps that eventually become planets, stars and galaxies. Back in the 1600s, Isaac Newton defined gravity as a universal force acting on all matter. According to his theory, the exact expression of gravity came down to mass and distance. The farther apart two particles are and the less massive they are, the less the gravitational force.
