THE BOOK OF COMMON PRAYER WHEN MY wife and I were seeing an English movie in Poona on 3 September 1939, there was an interruption and a grim announcement: Ladies and Gentlemen: we regret to announce that Great Britain and Germany are at war with each other from today.

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. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together 13.787±0.020 billion years ago,[11] and the universe has been expanding ever since. While the spatial size of the entire universe is unknown,[3] it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
