He is the Originator of the heavens and the earth.
“Do not they not see that the heavens and the Earth
were once one mass, then We rent them apart?”
“And it is We who have constructed the heaven with might,
and verily, it is We who are steadily expanding it.”
“Do not the Unbelievers see that the heavens and
the earth were joined together (as one unit of creation),
before We clove them asunder, and We made from
water every living thing. Will they not then believe?”
“and the heavens we created with might (power) and
we are expanding it.”
The overall Big Bang theory states that the universe started from an incredibly dense
singularity that exploded. All matter, light and energy came from that explosion.
The size of the universe increases as everything expands from this explosion.
The theory is that of an expanding universe, meaning that the universe
as a whole is expanding, instead of a static universe meaning
that matter is expanding into a statically sized space.
