The Big Bang theory as a research area encompasses the theoretical, observational, and computational study of the hot, dense early universe and its subsequent expansion, structure formation, and thermal history. It integrates general relativity, quantum field theory, nuclear physics, and plasma physics to model processes such as primordial nucleosynthesis, recombination, and inflation, and it interprets empirical data from the cosmic microwave background, large-scale structure surveys, and high-redshift observations. Research in this domain refines cosmological parameters, tests fundamental physics (e.g., dark matter, dark energy, curvature), and investigates deviations from or extensions to the standard ΛCDM cosmological model.
It may well take years to prove, but a pair of University of Miami astrophysicists could be on the verge of a cosmic breakthrough that will confirm the existence of primordial black holes and the role they play in one of ...
