Cosmology is a research area in astrophysics that investigates the large-scale properties, origin, composition, and dynamical evolution of the Universe as a whole. It integrates general relativity, quantum field theory, and observational astronomy to construct and test models such as the ΛCDM paradigm, characterized by dark energy, cold dark matter, and baryonic matter. Cosmology addresses the expansion history, cosmic microwave background anisotropies, structure formation, and primordial nucleosynthesis, using data from galaxy surveys, gravitational lensing, supernovae, and cosmic background experiments to constrain fundamental parameters and probe physics at energy scales inaccessible to terrestrial laboratories.
The universe may be trapped in its own comfort zone, and a researcher in the College of Engineering and Computer Science has helped explain why it cannot seem to leave. A new study suggests the universe could be locked into ...

The cosmic microwave background (CMB) is the universe's oldest light, leftover thermal radiation from about 380,000 years after the big bang. Maps of the CMB offer a picture of the "baby universe" as it was 13.8 billion years ...

If some aspects of cosmic topology turn out to be true, the idea that starships might voyage across the cosmos for hundreds of thousands of light-years without ever returning to the same neck of spacetime could be problematic.
