Question

which statements identify what astronomers currently know and think will happen with our universe? check all that apply.

the big bang produced dark energy, which accounts for some of the energy needed to expand the universe.

the vastness of space may contain a type of matter known as \dark matter.\

the universe is currently shrinking at a rapid rate.

the universe is currently expanding at an accelerating rate.

the big bang theory explains all the energy and matter discovered by scientists.

Explanation:

1. Statement 1: The Big Bang is associated with the origin of the universe, and dark energy is a component driving its expansion, so this is correct.
2. Statement 2: Dark matter is a hypothesized form of matter in the universe, and its existence is considered in the vastness of space, so this is correct.
3. Statement 3: Current astronomical evidence shows the universe is expanding, not shrinking, so this is incorrect.
4. Statement 4: Observations indicate the universe's expansion is accelerating, so this is correct.
5. Statement 5: The Big Bang theory does not explain all energy and matter (e.g., dark matter/energy details are still being explored), so this is incorrect.

Answer:

• The big bang produced dark energy, which accounts for some of the energy needed to expand the universe.
• The vastness of space may contain a type of matter known as "dark matter."
• The universe is currently expanding at an accelerating rate.
