Dark energy, a mysterious force thought to drive the accelerating expansion of the universe, is becoming a focal point for astronomers and cosmologists alike.Recent analysis conducted by the international Dark Energy Spectroscopic Instrument (DESI) collaboration has raised new questions about the nature of dark energy, often equated with a ‘cosmological constant.’ As researchers delve deeper into dark energy's effects, they utilize an expansive 3D map of the universe to understand its influence over billions of years.
