G299 Type Ia supernova remnant. Measurements from Type Ia supernovae, baryon acoustic oscillations (BAO), and the cosmic microwave background (CMB) hint that dark energy may evolve instead of staying fixed.
Fresh evidence suggests dark energy is not constant but slowly changing, hinting at new physics that could redefine how the universe expands.
