Some Sample Questions Found in this book :

Q 1) What is Cosmology?

It is the study of origin and evolution of Universe as a whole; it includes its history and destiny. In short, it is the study of Universe from beginning to the end. It does not take into consideration the Religious theories of the origin of the Universe. Cosmology is based on models formulated by the cosmologists using natural laws not supernatural causes.

Q 3) What is Big Bang Explosion?

Big Bang is the explosion of creation. In the beginning there was “point of singularity", which exploded to form the present Universe. The “point of singularity” was a pointless point, with no dimension, in which the entire energy of today’s Universe was found. Hawking had developed theories to show that it was with the point of singularity the Universe began. In simple terms, the Universe was born from the point which was boundless, endless and dimensionless but with infinite density.

Q 15) What was there before Big Bang explosion?

There was no yesterday to Big Bang. When this question was asked to Sir Roger Penrose, He said, “Asking this question is like asking, what is north of North Pole”. Standing on the North Pole and asking to show the north direction is totally meaningless Space, Time and everything was born from the very moment of the Big Bang explosion. The question of probing what existed before Big bang is not within the jurisdiction of science. The Universe is not beginningless, it had a beginning nearly 13.75 billion years ago. Modern cosmology gives evidence to it. Universe is also not endless, it will have an end.

Q 85) Is there any proof for the Big Bang explosion?

The entire Universe is filled with “Cosmic Microwave Background Radiation”. In simple terms, the Universe has a constant temperature of 2.7 º Kelvin, Scientists Arno Penzias and Robert Wilson of US had accidentedly found it in 1965. This Cosmic Waves are the remaining cosmic energy from Big bang explosion.

Explorers COBE (1998), BOOMERGANG (1998), WMAP (2001) had proved the existence of “Cosmic Microwave Background Radiation”. In 2006, Physicists John Mather and George Smoot were given Nobel Prize for their discovery, which made many people to accept Big Bang theory.
