"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," Hawking writes.
"It is not necessary to invoke God to light the blue touch paper and set the universe going."Hawking has for a long time been trying to link the two major cornerstones of modern physics-Einsteins General Theory of Relativity, which concerns gravity and large objects and quantum theory, which covers subatomic particles. His latest claim is likely to spark much debate between believers and atheists and probably help him sell a few million more copies of his new book.
