6. Mai 2024 · Learn how gravity works, what it does, and how it affects us and the universe. Find out about gravity on Earth, in space, and in black holes.
2. Mai 2024 · Die Gravitation tritt demnach nicht wie in der klassischen Physik als eine bestimmte Kraft auf, die auf den Körper wirkt und eine Beschleunigung verursacht, sondern als eine Eigenschaft der Raumzeit, in der der Körper sich kräftefrei bewegt. Gravitation wird auf diese Weise als ein rein geometrisches Phänomen gedeutet.
Vor 4 Tagen · General relativity. 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.
12. Mai 2024 · Learn about the physical constant G that describes the gravitational attraction between two objects, and how it was measured by Cavendish and Michell. Find out the value, units, and facts of G, and how it relates to general relativity and equivalence principle.

Vor 5 Tagen · Albert Einstein. In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times. The first extant sources discussing such theories are found in ancient Greek philosophy.
6. Mai 2024 · 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.
6. Mai 2024 · Learn about gravity and its effects on Earth, Sun, Solar System and Universe. Explore topics such as black holes, barycenter, gravitational waves, dark matter and more with games, activities and videos.
