Hace 4 días · Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.
Hace 4 días · Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by. A gravitational wave is an invisible (yet incredibly fast) ripple in space. We’ve known about gravitational waves for a long time.
Hace 2 días · Sin embargo, el entusiasmo y la persistencia de los seguidores podrían ser un factor determinante para que ‘Gravity Falls’, temporada 3, se convierta en una realidad en el futuro próximo.
Hace 4 días · What does gravity have to do with weight? Earth's gravitational pull is what keeps the Moon in orbit around our planet. Voyager 1 snapped this picture of Earth and the Moon from a distance of 7.25 million miles.
Hace 1 día · Gravitational waves are waves of the intensity of gravity that are generated by the accelerated masses of binary stars and other motions of gravitating masses, and propagate as waves outward from their source at the speed of light. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the ...

Hace 3 días · Al-Biruni and Al-Khazini studied the theory of the centre of gravity, and generalized and applied it to three-dimensional bodies. Fine experimental methods were also developed for determining the specific gravity or specific weight of objects, based the theory of balances and weighing.
