Abstract

This article explores a thought experiment involving a massive object within a conceptual cubic region of space. It explains that the gravitational well, or the curvature of space-time created by this object, will be spherical, regardless of the cubic boundaries. Drawing upon Albert Einstein's General Theory of Relativity, the article clarifies that gravity is a manifestation of the curvature of space-time, which is determined by the object's mass distribution and its inherent symmetry. The analogy of a "spherical pit" on a rubber sheet is used to simplify this concept, demonstrating how the shape of the gravitational field is a direct consequence of the object's uniform mass, not the container it is in.
