Gravitational waves are transient displacements in a gravitational field—generated by the motion or acceleration of gravitating masses—that radiate outward...

Newton's law of universal gravitation says that every particle attracts every other particle in the universe with a force that is proportional to the...

A gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is predicted to be so intense that spacetime...

In astrophysics, gravitational compression is a phenomenon in which gravity, acting on the mass of an object, compresses it, reducing its size and increasing...

Gravitational energy or gravitational potential energy is the potential energy a massive object has due to its position in a gravitational field. It is...

Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward...

Look up gravitation in Wiktionary, the free dictionary. Gravitation is the mass-proportionate force of attraction among matter. Gravitation may also refer...

In physics, a gravitational field or gravitational acceleration field is a vector field used to explain the influences that a body extends into the space...

In physics and general relativity, gravitational redshift (known as Einstein shift in older literature) is the phenomenon that electromagnetic waves or...

A gravitational lens is matter, such as a cluster of galaxies or a point particle, that bends light from a distant source as it travels toward an observer...

gravitational mass determines the strength of the gravitational field generated by an object. Passive gravitational mass measures the gravitational force...

The term gravitational shielding refers to a hypothetical process of shielding an object from the influence of a gravitational field. Such processes,...

A gravitational soliton is a soliton solution of the Einstein field equation. It can be separated into two kinds, a soliton of the vacuum Einstein field...

Gravitational biology is the study of the effects gravity has on living organisms. Throughout the history of the Earth life has evolved to survive changing...

Gravitational capture occurs when one object enters a stable orbit around another (typically referring to natural orbits rather than orbit insertion of...

In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag). This is the...

In theoretical physics, a gravitational anomaly is an example of a gauge anomaly: it is an effect of quantum mechanics — usually a one-loop diagram—that...

Gravitation (Japanese: グラビテーション, Hepburn: Gurabitēshon) is a yaoi manga series written and illustrated by Maki Murakami. The story follows the attempts...
