Posicone vs negacone: different gravitational lensing effects (converging vs diverging) produced by a positive or a negative mass, due to the opposite amount of curvature they create in spacetime.
Summary
[edit]
| Description |
English: Curvature produced by a positive mass vs a negative mass on a 2D surface embedded in a 3D space: "posicone" (positive amount of curvature) vs "negacone" (negative amount of curvature, giving a hyperbolic geometry). Path of photons along the null-geodesics of such surfaces: a positive mass produces positive (converging) gravitational lensing, while a negative mass produces negative (diverging) gravitational lensing. |
