Is dark energy constant? An experiment called the Dark Energy Spectroscopic Instrument (DESI) has been studying baryon acoustic oscillations, which are sound waves from the early universe. Using this data, DESI has found a statistically significant deviation from the cosmological constant, indicating that dark energy may be evolving.

The Dark Energy Spectroscopic Instrument (DESI) collaboration published a new analysis of dark energy on 19 March 2025. DESI created the largest three-dimensional map of the universe ever made, using data from nearly 15 million galaxies and quasars collected in the first three years of observations. This map covers 11 billion years of cosmic history. Dark energy has long been considered a constant (called the “cosmological constant” in the standard Lambda CDM model), that is, a force that does n
