The Big Bang theory regarding the origin of the universe was given by _____.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Georges Lemaître
The Big Bang theory says that the universe began from a single, extremely hot and dense point about 13.8 billion years ago and has been expanding ever since.
It was put forward in 1927 by the Belgian astronomer and priest Georges Lemaître, who called the starting point the “primeval atom”. Edwin Hubble’s finding of 1929, that distant galaxies are moving away from us, supported the idea of an expanding universe.
