Einstein's General Theory of Relativity
Question
Consider the following phenomena:
Which of the above is/are the prediction/predictions of Albert Einstein's General Theory of Relativity, often discussed in media?
- 1.
Light is affected by gravity.
- 2.
The Universe is constantly expanding.
- 3.
Matter warps its surrounding space-time.
Options
1 and 2 only
3 only
1 and 3 only
1, 2 and 3
Explanation
Einstein's General Theory of Relativity (1915) makes several key predictions: (1) Light bends due to gravity (gravitational lensing), confirmed by Eddington in 1919. (2) The universe is not static but dynamic; while the Big Bang theory and evidence of expansion came later, the mathematics of GR allows for an expanding universe (Friedmann solutions). (3) Massive objects curve spacetime around them, which is a central prediction of GR. All three phenomena are indeed predictions or implications of General Relativity. Statement 2, while confirmed observationally, is consistent with GR's framework. > GR predicts gravity bends light, matter curves spacetime, and allows dynamic universe expansion. Answer: (d).
