A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build vast ...

New results from the Dark Energy Spectroscopic Instrument (DESI ... This first light is referred to as the "cosmic microwave background" or "CMB," and it can still be observed today.

However, by combining them with observations of cosmic microwave background and supernovae, the best fitting model is one involving a dark energy that evolved over cosmic time, and that will ...

called the cosmic microwave background, the DESI data shows that dark energy’s impact could be weakening over time. “If this continues then eventually dark energy will not be the dominant forc ...

The Dark Energy Spectroscopic Instrument used millions ... leftover from the dawn of the universe (the cosmic microwave background or CMB), exploding stars (supernovae), and how light from distant ...
