How does gravity hold the universe together
WebAug 16, 2010 · Gravity holds your feet down to the ground because the mass of the planet exerts a gravitational pull on the mass of your body. In fact, gravity stirs up an attraction between any two objects in the universe: moons, dust motes, coyotes -- you name it. Wherever you find matter, you'll find gravity. WebThis beneficial property makes gravity the universal "Elmer's Glue" which binds the universe together. Even the distant galaxies, which appear to have been created with an outward expanding motion, are gradually slowing due to the inward gravity pull from all other galaxies in the universe. Gravity cannot be fumed off or shielded in any way.
