Einstein’s General Theory of Relativity predicts that (1) light follows curved space-time and is therefore bent by gravity, (2) cosmological solutions of the field equations allow and indeed imply an expanding universe, and (3) mass–energy warps the surrounding space-time fabric. All three statements are therefore correct.([sprintupsc.com](https://sprintupsc.com/PreviousYearsWeb/upsc-prelims-2018-answer-key.html))
