Question

which statements describe the principles of the big bang theory? select two options.
the universe is continuing to expand.
the universe stretched from a single point.
the universe resulted from the collision of light and dark energy.
the universe expanded, but its size is now remaining constant.
the universe is slowly collapsing and getting smaller.

Explanation:

1. The Big Bang theory states that the universe began from a singularity (a single point) and has been expanding ever since. So "The universe is continuing to expand" is correct as the expansion is ongoing.
2. "The universe stretched from a single point" is also correct as the theory proposes the universe originated from a singularity and expanded (stretched) out.
3. The universe did not result from collision of light and dark energy (so third option is wrong).
4. The universe is not constant in size (fourth option is wrong) and it's not collapsing (fifth option is wrong).

Answer:

A. The universe is continuing to expand.
B. The universe stretched from a single point.
