big bang model

In particular, the big bang model of the universe begins with a singularity—a point that appeared out of nothing and contained the precursors of everything in the universe in a region so small that it had essentially no size at all.

If those gravitational waves from the early universe had truly been found, it would lend support to a theory known as cosmic inflation, an element of the Big Bang model of the early universe.

The “hot big bang” model said the cosmos began extremely small, hot and dense and then cooled and spread out over time.

It goes the other way as well: the Catholic Church, for example, has affirmed many times that it acknowledges the fact of evolution, the Big Bang model of cosmology and the possible existence of extraterrestrial life.

It was 1963, and during an astronomy conference Hoyle fell into a conversation with Robert Dicke, a physicist who was planning to search for the cosmic microwaves predicted by the big bang model.
