Correct Answer: Speed of light is always same. ​. Statement 1 : Wrong, as the doppler effect proves that universe is expanding Statement 2 : Wrong, as the Gravitational power is dependent on the mass of the object. With change in Mass, there is change in Gravity Statement 3 : Though light travels in a straight line, Gravity can bend this light. Statement 4 : Most accurate, as the speed of light does not change in Vacuum. A light-year is the distance light travels in one Earth year in Vacuum. So it is a constant that can be used for measurement.
