Contribution

It provides a comprehensive overview of unresolved problems in cosmology related to dark components and galaxy formation, emphasizing future experimental directions.

Findings

Current issues in dark matter and dark energy are central to cosmological research.

Experimental efforts aim to probe the early universe and fundamental cosmic components.

Understanding galaxy formation remains a major challenge in cosmology.

Abstract

I review the current status of Big Bang Cosmology, with emphasis on current issues in dark matter, dark energy, and galaxy formation. These topics motivate many of the current goals of experimental cosmology which range from targeting the nature of dark energy and dark matter to probing the epoch of the first stars and galaxies.
