Kinetic energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion.It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Ha...

Schwarzschild geodesics
In general relativity, the geodesics of the Schwarzschild metric describe the motion of particles of infinitesimal mass in the gravitational field of a central fixed mass M. The Schwarzschild geodes...

Deriving the Schwarzschild solution
The Schwarzschild solution is one of the simplest and most useful solutions of the Einstein field equations (see general relativity). It describes spacetime in the vicinity of a non-rotating massive ...
Shapiro delay
The Shapiro time delay effect, or gravitational time delay effect, is one of the four classic solar system tests of general relativity. Radar signals passing near a massive object take slightly longe...
Crowd Farm
The Crowd Farm is a project conceived by MIT students Tad Juscyzk and James Graham and announced at the Holcim Forum 2007 awards ceremony. The goal of the project is to convert the energy of human mo...
Gravitational lens
A gravitational lens refers to a distribution of matter (such as a cluster of galaxies) between a distant source and an observer, that is capable of bending the light from the source, as it travels to...

Schwarzschild metric
In Einstein's theory of general relativity, the Schwarzschild metric (also known as the Schwarzschild vacuum or Schwarzschild solution) is the solution to the Einstein field equations that describes t...
