Hawking's new book, The Grand Design, co-authored by Caltech physicist Leonard Mlodinow, described that the Big Bang was an inevitable consequence of the laws of physics. The 208 paged 'The Grand Design' will release soon.
"Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going," describes Hawking in the book.
Hawking described that the discovery of other planets and solar systems, which has cast further doubt on the necessity of God.
"That makes the coincidences of our planetary conditions, the single sun, the lucky combination of Earth-sun distance and solar mass, far less remarkable, and far less compelling as evidence that the Earth was carefully designed just to please us human beings," he added.
Hawking had previously argued that belief in a creator was not incompatible with science.
