- DESI collaboration found evidence suggesting dark energy might be weakening over time.
- DESI is a galaxy survey using a 4-meter telescope with 5,000 robotic fiber optic cables.
- The survey has cataloged over 13 million galaxies, aiming for 50 million.
- Baryon Acoustic Oscillations (BAO) are used to study large-scale universe structures.
- BAO are remnants of sound waves from the early universe, acting as 'standard rulers'.
- DESI's BAO measurements suggest deviations from standard cosmology, hinting at evolving dark energy.
