Question

which statements describe some of the original ideas proposed about the universe during the big bang? check all that apply. the universe exploded. the universe was opaque. the universe was one second old. the universe was very hot and dense. the universe expanded from a single point.

Explanation:

The Big - Bang theory proposes that the universe expanded from a single, extremely hot and dense point. Initially, it was opaque. Saying the universe "exploded" is a misnomer as it was an expansion. The age of "one - second old" is a specific time point rather than an original fundamental idea about the nature of the early universe at the start of the Big - Bang concept.

Answer:

The universe was opaque.
The universe was very hot and dense.
The universe expanded from a single point.
