Gravitational Lensing
Definition of Gravitational Lensing as it relates to Science, Space Science, Cosmology
Gravitational lensing, an essential aspect of cosmology, investigates how light from distant objects is bent by the gravitational pull of massive structures in the universe. It provides valuable insights into the distribution and nature of dark matter, the expansion of the universe, and the properties of black holes. This phenomenon was first predicted by Einstein's theory of general relativity and has since been confirmed through various astronomical observations, opening up new ways to study the cosmos.
