why light under high gravity environment does not always follow a straight line?

Gravity affects the path of light by bending it, causing it to follow a curved trajectory. This is known as gravitational lensing and is a result of Einstein's theory of general relativity.
Light follows a straight path in a vacuum, but when it encounters a massive object, such as a planet or star, its path is altered due to the gravitational pull of the object. This causes the light to curve and not travel in a straight line.
The amount of gravity present determines how much light will be bent. Objects with higher mass and density, such as black holes, have a stronger gravitational pull and can cause more significant bending of light.
No, once light enters the event horizon of a black hole, it cannot escape its gravitational pull. This is because the escape velocity at the event horizon is greater than the speed of light, making it impossible for light to escape.
Gravitational lensing allows us to see objects that would otherwise be hidden behind massive objects, such as galaxies or clusters of galaxies. It also allows us to study the properties of these objects, such as their mass and composition, by analyzing the distortion of light caused by their gravitational pull.
