Orrery. A small orrery showing Earth and the inner planets. An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often ...
The scale of the planets is the same as the scale between them, and the planets are represented by everyday objects; the Earth is a peppercorn, Jupiter is a walnut, and Neptune is a coffee bean.

The Antikythera mechanism ( / ˌæntɪkɪˈθɪərə / AN-tik-ih-THEER-ə, US also / ˌæntaɪkɪˈ -/ AN-ty-kih-) [ 1][ 2] is an Ancient Greek hand-powered orrery (model of the Solar System), described as [weasel words] the oldest known example of an analogue computer [ 3][ 4][ 5] used to predict astronomical positions and eclipses decades in ...
A matrioshka brain [1] [2] is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It was proposed in 1997 by Robert J. Bradbury (1956–2011 [3] ). It is an example of a class-B stellar engine, employing the entire energy output of a star to drive computer systems. [4] This concept derives its name from the ...
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe ...
SpaceEngine creates a 1:1 scale three-dimensional planetarium representing the entire observable universe, combining real astronomical data with scientifically accurate procedural generation algorithms. Users can travel through space in any direction or at any speed and can move forwards or backwards in time. [4] SpaceEngine is currently in ...
The Kardashev scale can be a relevant tool for preventing catastrophes, whether human or natural, according to Richard Wilson, who relates this scale to the power of destruction, in TNT. A Type I civilization would use 25 megatons of equivalent TNT per second, a Type II civilization 4 × 10 9 times more (4 billion hydrogen bombs per second ...
The Time Machine (also marketed as H. G. Wells' The Time Machine) is a 1960 American period post-apocalyptic science fiction film based on the 1895 novella of the same name by H. G. Wells. It was produced and directed by George Pal , and stars Rod Taylor , Yvette Mimieux , and Alan Young .
