Description

Current cosmological observations have established the accelerated expansion of the Universe, yet the physical nature of dark energy remains elusive. We summarize the current status of cosmology as inferred from observational data and discuss the implications for the nature of dark energy. We review the main observational probes, highlight existing tensions between datasets within the standard ΛCDM framework, and present theoretical and experimental efforts aimed at addressing these challenges.
