Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of years ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda Cold Dark Matter, or ΛCDM, it weaves together dark energy, dark matter, and ...

In a new study, scientists began pondering a pretty wild question: What if black holes can convert dead star matter into dark energy, the mystery force driving the acceleration of the expansion of the ...

Dark energy is still one of the greatest cosmic mysteries. For all the time, money and telescopes that humanity has used to uncover its nature, scientists are still asking a fundamental question: What ...

For a quarter century, cosmologists have treated dark energy as a fixed, featureless pressure that steadily drives galaxies apart. Now a convergence of massive sky surveys and giant computer models is ...

Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance. The force is enormous — it makes up nearly 70% of ...

The universe is expanding and that expansion is accelerating under the power of dark energy and eventually all matter and energy will be dispersed over such unthinkable distances that nothing can stop ...

Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing ...
