flat space
Two-dimensional expanse
Flat space is a region of spacetime with no curvature—no gravitational fields bending its geometry.
In physics, it describes the idealized emptiness far from any massive objects, where light travels in straight lines and clocks tick at the same rate.
In flat space, two parallel lines never meet.
The term contrasts with curved spacetime near stars or black holes.
