Question

How did life begin? ... Are we alone in the universe What is the universe made of? ... ​

Answer 1

Answer:

1)किसी वक्त ब्रह्मांड एक परमाणु से भी छोटा था। सूक्ष्म बिंदु में करीब 14 अरब साल पहले महाविस्फोट हुआ। इसे ही बिग बैंग कहते हैं। ... इसी से ब्रह्मांड की शुरुआत हुई

2)Alone, in all that space? Not likely. Just do the numbers: Several hundred billion stars in our galaxy, hundreds of billions of galaxies in the observable universe, and 150 planets spied already in the immediate neighborhood of the sun.

3)The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
