Full Description
The examination will cover the concepts of dark matter and dark energy, focusing on their roles in the cosmic expansion and universe structure. Emphasis will be placed on current models and evidence supporting these phenomena.
Understanding dark matter and dark energy is crucial for modern cosmology, as they constitute a significant portion of the universe's total energy density, directly influencing its expansion and fate.
Students will be evaluated on their ability to articulate the evidence for dark matter and dark energy, including galactic rotation curves, gravitational lensing, and observations of distant supernovae.
Candidates are encouraged to connect theoretical principles with observational data, demonstrating an integrated understanding of how these factors affect cosmological models.
