How does the concept of space-time fabric explain the bending of light around massive objects?

The concept of space-time fabric, as described by Einstein's theory of general relativity, explains how massive objects like stars and black holes can bend light. According to this theory, massive objects create a "dent" in the fabric of space-time, causing light to follow a curved path around them. This bending of light is known as gravitational lensing, and it is a key prediction of general relativity that has been observed and confirmed by astronomers.
