What is the study of the universe?

Cosmology
Astronomy
Quantum Mechanics
Astronautics

The correct answer is: Cosmology

Cosmology is the study of the universe, its origins, evolution, and structure, including the laws of physics that govern it. Astronomy is the study of celestial objects and phenomena, such as stars, planets, and galaxies. Quantum Mechanics is a branch of physics that studies the behavior of matter and energy at a very small scale, such as atoms and subatomic particles. Astronautics is the aeronautical science of designing, building, and operating spacecraft. While all of these fields may involve some study of the universe, cosmology specifically focuses on the big picture and addresses questions about the universe as a whole. Therefore, it is the most accurate answer to the question.
