Question

give some lines about gravitational lensing

Answer 1

$hello$

$here \: is \: your \: answer$

Gravitational lensing is caused by a massive body between a distant object and ourselves. It can create the appearance of two or more objects where there is really only one. The light from the object gets bent round the massive body in between.

The massive body, such as a galaxy or black hole, creates a very strong gravitational field in space. The exact nature of the effect depends on:

relative distance and position between observer,

lens and lightsource

size of the lens

mass inside the lens

$hope \: its \: help \: for \: you$

Answer 2

Gravitational lensing is an effect of Einstein’s theory of general relativity – simply put, mass bends light. The gravitational field of a massive object will extend far into space, and cause light rays passing close to that object (and thus through its gravitational field) to be bent and refocused somewhere else.
