Cosmological models are theoretical constructs that describe the large-scale properties and dynamics of the universe, integrating observations from astronomy and physics to explain phenomena such as the expansion of the universe and cosmic microwave background radiation. These models are essential for understanding the universe's origin, structure, evolution, and ultimate fate, often relying on principles from general relativity and quantum mechanics.

Theoretical constructs are abstract concepts derived from theoretical frameworks that help in understanding and explaining phenomena within a particular field of study. They are essential in the research process, guiding the formulation of hypotheses, research designs, and interpretations of findings.

Observations from physics

The expansion of the universe refers to the observation that galaxies and other cosmic structures are moving away from each other, suggesting that the universe has been growing since the Big Bang. This phenomenon is supported by the redshift of light from distant galaxies and is a fundamental aspect of modern cosmology, indicating that space itself is stretching over time.

Cosmic microwave background radiation is the thermal remnant from the Big Bang, providing a snapshot of the universe when it was just 380,000 years old. It is a nearly uniform background of microwave radiation that fills the universe and is a critical piece of evidence for the Big Bang theory, offering insights into the early conditions and subsequent evolution of the cosmos.
