PLEASE MARK AS BRAINLIEST

Explanation:

The universe (Latin: universus) is all of space and time[a] and their contents,[10] including planets, stars, galaxies, and all other forms of matter and energy. While the spatial size of the entire universe is unknown,[3] it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light-years in diameter. In various multiverse hypotheses, a universe is one of many causally disconnected[11] constituent parts of a larger multiverse, which itself comprises all of space and time and its contents;[12] as a consequence, ‘the universe’ and ‘the multiverse’ are synonymous in such theories.
