Here is a quote from a topologist:
Embedding refers to how a topological object—a graph, surface, or manifold—is positioned in space. The concept of embedding is central to the idea of an extrinsic view of topology simply because we cannot view something from the outside unless it is somehow...
In a paper by Lu and Suen entitled 'Extrinsic Curvature Embedding Diagrams' the abstract makes the statement: "Embedding diagrams have been used extensively to visualize the properties of curved space in Relativity. We introduce a new kind of embedding diagram based on the extrinsic curvature...
A help to understand how gravity works in our universe is called an embedding diagram. It is a three-dimensional representation of what happens to a two-dimensional universe in the presence of mass, i.e. the plane is distorted into a 'gravity' pit.
What happens if we extend this concept to...
