lensing造句怎么写

Gravitational lensing works like this: When a large nearby object like a galaxy blocks a distant object, such as another galaxy, the light can detour around the blockage.

Because of their heft, the clusters act like giant cosmic lenses, magnifying, distorting and bending any light that passes through them - an effect known as gravitational lensing.

The sphere, for instance, represents how space is bent around a star or other mass - light passing through this warped space bends in an effect called gravitational lensing.
