“Gravity” is a stage which is depicting Einstein’s relativity theory, where time and space operate as a 3 dimensional fabric and is bent by mass.
The resulting curvature of space-time is responsable for the movement of planets, moons comets and the spiraling gallaxies. Gravity could be created in different ways, either as a small installation of 5x10x2,5 m or as a 20x30 meter stage. 

This drawing is showing a cross section of 20m width of the stage.
It would be a travelling installation that can be used as a scenography for performance arts. On this stage the performers and the public mix.
They all access the stage through steps and exit through the hole in the center that functions as a slide. Some of them might even have rollerblades and will turn around the earth like visiting asteroids or comets.

The distortion of the stage is representing gravity. Gravity according to Einstein’s theory of relativity is the distortion of the field of space-time. This means the mass of a planet or a star is bending the space-time fabric in the same way a bowling ball would bend an elastic trampoline.
When a tennis-ball is thrown on this stage it will turn in ellipses around the center in exactly the same way the earth turns around the sun, or the moon around the earth. The only difference is, that this occurs in space in 3 dimensions instead of just 2.

This stage is a place for education about physics and space, but it is also a place for celebration and even ritual. Through performances and storytelling, we learn about the universe we are a part of and the physical laws that we are an extension of. 
The story of the cosmos is a story about us. As in an initiation ritual we are invited to dive in the hole in the center to experience a kind of “second birth” or cosmic baptism: We are children of the universe.
