View source for Gravitational lensing

'''Gravitational lensing''' refers to the deflection of light caused by the gravitational influence of mass along its path. It is a consequence of spacetime curvature described by general relativity.

Gravitational lensing is discussed in astrophysics, cosmology, and observational astronomy.

== Status ==
Gravitational lensing is observed in multiple regimes, including strong, weak, and microlensing. It is used to study mass distributions, dark matter, and distant astronomical objects.
