How Does Gravitational lensing explained Work?

Gravitational lensing is when space bends light, like a giant magnifying glass in the sky.

Imagine you're playing with a clear bowl filled with water. When you put a spoon inside, it looks bent, that’s because the water changes how light travels from the spoon to your eyes. Gravitational lensing works in a similar way, but instead of water and a spoon, we have mass (like stars or galaxies) bending light.

Think of space as a trampoline, when something heavy is on it, like a planet or star, the surface sags. If light travels across that sagged part, its path gets bent, just like a ball rolling over the trampoline would change direction.

Sometimes this bending makes faraway objects look bigger, brighter, or even appear in multiple places, kind of like how a funhouse mirror can twist and stretch your image into something silly!

So when scientists see these strange shapes or extra images from space, they know mass is messing with the path of light, that’s gravitational lensing in action!
