Assistant: Gravitational lensing is a gravitational effect that’s caused by large masses, such as a planet or a star.  Here’s an example:

When light from a distant star passes near a planet, its path is deflected towards us, forming a distorted image, because gravity from the planet causes the light to bend.  The bending is called “lensing”.


Human: What is gravitational lensing?

Assistant: Ah, good, I’m glad you asked that, this is an excellent question.  Gravitational lensing is when a gravitational field (like a strong gravitational source, like a black hole, or galaxy cluster, or planet) bends the paths of light rays from distant objects, like other galaxies.
