Dark energy is studied through a variety of observational methods, including:
Cosmic Microwave Background (CMB): Observations of the CMB provide clues about the universe's early conditions and how dark energy has influenced its evolution. Large Scale Structure (LSS): Studies of the distribution of galaxies help scientists understand the influence of dark energy on cosmic structure formation. Supernova Surveys: Ongoing surveys of distant supernovae provide more data on the universe's expansion history.
