Black holes of stellar mass are expected to form when heavy stars collapse in a supernoOOOOoooOOooOOOoooOOoOva * xD* at the end of their life cycle. After a black hole has formed it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may be formed.

gravitational lensing refers to a distribution of matter between a distant source and an observer, that is capable of bending (lensing) the light from the source, as it travels towards the observer. This effect is known as gravitational lensing and is one of the predictions of Albert Einstein's
