What specific value does the Hubble Constant measure in cosmology?
Answer
The expansion rate of the universe
The Hubble Constant is a fundamental metric used to determine the expansion rate of the universe. This constant is a critical component for calculating the age and size of the cosmos. Before space-based observations, measurements of distances to remote galaxies were imprecise, leading to widely varying estimates for the age of the universe. Refining this constant allows scientists to test core cosmological models and turn the study of the universe into a high-precision science.
