Cosmology

Why it matters

• Provides a scientific framework for understanding the fundamental laws governing space, time, and matter.
• Facilitates the study of dark matter and dark energy, which constitute the majority of the universe's mass-energy content.
• Informs the development of advanced instrumentation and observational techniques in high-energy physics and space exploration.

How it is asked

Candidates should focus on the conceptual understanding of the Big Bang theory, the expansion of the universe, and the role of cosmic microwave background radiation in validating cosmological models.
