Consider the following phenomena :
1. Light is affected by gravity.
2. The Universe is constantly expanding.
3. Matter warps its surrounding space-time.
Which of the above is/are the prediction/predictions of Albert Einstein's General Theory of Relativity, often discussed in media ?

Correct Option: (d) 1, 2 and 3

Albert Einstein's General Theory of Relativity (1915) fundamentally predicted that gravity is the curvature of space-time caused by mass and energy (statement 3), that massive objects warp surrounding space-time, and that light passing near a massive body is bent or affected by gravity (statement 1). Furthermore, cosmological solutions to the field equations also indicated an expanding universe (statement 2). Therefore, all three phenomena are predictions of the theory.
