diffhist Four-dimensional space 20:50 −1,187 David Eppstein talk contribs (Undid revision 1302658695 by KeyunT (talk) unsourced, and this article is on 4d Euclidean space, not so much general relativistic space-time) Tag: Undo
diffhist Four-dimensional space 20:25 +1,187 KeyunT talk contribs (→Dimensional analogy: In theoretical physics, wormholes are exact mathematical solutions to Einstein’s field equations that represent bridges or tunnels through spacetime. These constructs require non-trivial topology, often embedded in higher-dimensional manifolds, and are commonly used to illustrate the possibility of connecting distant points in 3D space through a 4D or higher spatial dimension.)
