(See: Stress–energy tensor) If the masses move, the curvature of spacetime changes. If the motion is not spherically symmetric, the motion can cause gravitational waves which propagate away at the speed of light. [10] As a gravitational wave passes an observer, that observer will find spacetime distorted by the effects of strain. Distances ...
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.
Einstein predicted that when really heavy objects move through spacetime — the. Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently ...
[citation needed] However, it permits distortions in spacetime that allow an object to move faster than light from the point of view of a distant observer. [citation needed] One such distortion is the Alcubierre drive, which can be thought of as producing a ripple in spacetime that carries an object along with it.
Hawking was concerned about the future emergence of a race of "superhumans" that would be able to design their own evolution [345] and, as well, argued that computer viruses in today's world should be considered a new form of life, stating that "maybe it says something about human nature, that the only form of life we have created so far is ...

The equation for universal gravitation thus takes the form: F = G m 1 m 2 r 2 , {\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}},} where F is the gravitational force acting between two objects, m 1 and m 2 are the masses of the objects, r is the distance between the centers of their masses , and G is the gravitational constant .
Video simulation of the merger GW150914, showing spacetime distortion from gravity as the black holes orbit and merge. The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. [1]
