gravitationslensing
Gravitational lensing is a phenomenon where massive objects warp the fabric of spacetime, causing light from more distant objects to bend as it passes by. This bending effect is analogous to how a glass lens focuses light. Albert Einstein's theory of general relativity predicts that gravity can curve light, a prediction that has been repeatedly confirmed by astronomical observations.
The most significant gravitational lenses are often galaxies or clusters of galaxies, whose immense mass creates
Astronomers utilize gravitational lensing as a powerful tool in their research. It allows them to study distant
