What would happen to earth if the sun suddenly disappears ? A. The earth immediately experiences the lack of sun light. B. The earth experiences the lack of sun light after about eight minutes. C. The earth immediately experiences the lack of gravitation. D. The earth experiences the lack of gravitation after about eight minutes. Choose the correct answer :

Both light and gravity propagate at the speed of light (approximately 299,792 kilometers per second). The average distance between the Sun and the Earth is about 150 million kilometers. The time it takes for light (and gravitational influence) to travel from the Sun to the Earth is approximately: Time = Distance / Speed = (150 x 10^6 km) / (300,000 km/s) = 500 seconds = 8 minutes and 20 seconds (approximately 8 minutes). Therefore, if the Sun were to disappear suddenly, we would continue to see light from it and feel its gravitational pull for about eight minutes before noticing its absence.
