Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda ...

For a while now, there has been a problematic mystery at the heart of the standard cosmological model. Although all observations support the expanding universe model, observations of the early period ...

You can journey to the ends of the earth in search of success,” 19th-century Baptist preacher Russell Conwell is said to have ...

DESI observations suggest black holes may generate dark energy by consuming stellar matter. The idea resolves puzzles about neutrino mass and cosmic expansion. These are remarkable times for probing ...

Robert Brandenberger argues that the unchanging cosmological constant of the ΛCDM model is theoretically problematic.

The long and continuing quest to understand dark energy has entered exciting new territory. First discovered in the 1990s, dark energy has come to feel like a familiar face of the cosmos. Astronomers ...

ANAHEIM, Calif. — Change is in the air. New data strengthen a hint that dark energy, long thought to be a constant force in the universe, might change over time. Dark energy explains the observation ...

A new study suggests that primordial black holes (PBHs)—hypothetical remnants from the early universe—might be on the verge of an unprecedented cosmic event: an explosion observable with current ...

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy. Dark Energy Spectroscopic Instrument (DESI) collects data ...
