Model-Independent Measurements:
New Universal Constant:
The expansion rate of the universe is measured through various methods, including distant supernovae, galaxy clustering, and real-time observations of hydrogen signals. These methods collectively indicate an accelerating expansion, influenced by inhomogeneities and potentially driven by a new form of energy or a universal constant. Understanding these dynamics is crucial for comprehending the universe's past, present, and future evolution.
