Question

which statement accurately describes the universe?
○ the universe consists of all the energy made by the sun and stars.
○ the universe consists of all physical objects on earth and in space.
○ the universe consists of all matter and energy.
○ the universe consists of solar systems which contain galaxies.

Explanation:

• Option 1: The universe is not just energy from Sun and stars; it includes more, so incorrect.
• Option 2: It's not just physical objects; matter and energy in various forms exist, so incorrect.
• Option 3: The universe encompasses all matter (like planets, stars, atoms) and energy (like light, heat, gravitational energy), so this is accurate.
• Option 4: Galaxies contain solar systems, not the other way around, so this is incorrect.

Answer:

C. The universe consists of all matter and energy.
