Slow motion computer simulation of the black hole binary system GW150914 as seen by a nearby observer, during 0.33 s of its final inspiral, merge, and ringdown.The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as spacetime itself is distorted and dragged around by the rotating black holes.
Before Newton’s law of gravity, there were many theories explaining gravity. Philoshophers made observations about things falling down − and developed theories why they do – as early as Aristotle who thought that rocks fall to the ground because seeking the ground was an essential part of their nature.

Eccentric behavior is often considered whimsical or quirky, although it can also be strange and disturbing. Many individuals previously considered merely eccentric, such as aviation magnate Howard Hughes, have recently been retrospectively diagnosed as having had mental disorders (obsessive–compulsive disorder in Hughes' case).

In the absence of any other forces, a particle orbiting another under the influence of Newtonian gravity follows the same perfect ellipse eternally. The presence of other forces (such as the gravitation of other planets), causes this ellipse to rotate gradually. The rate of this rotation (called orbital precession) can be measured very accurately.
In 1905, Henri Poincaré proposed gravitational waves, emanating from a body and propagating at the speed of light, as being required by the Lorentz transformations [24] and suggested that, in analogy to an accelerating electrical charge producing electromagnetic waves, accelerated masses in a relativistic field theory of gravity should produce ...
Eccentric exercise vs. concentric exercise “Eccentric and concentric exercises are just two parts of any movement,” explains Mike Julom, ACE-certified personal trainer, CrossFit athlete, and ...
Eccentric, concentric, and isometric phases are all distinct parts of most exercises you do in your workouts. Here's what they mean and how to use them. Eccentric, concentric, and isometric phases ...
