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...

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

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

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

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

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

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 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,...

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

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...

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...

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...

lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational potential...

A gravitational keyhole is a tiny region of space where a planet's gravity would alter the orbit of a passing asteroid such that the asteroid would collide...

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