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 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 ...

Physicists propose that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early universe ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

Dark energy does not exist, some scientists have claimed – which could help get rid of one of the universe’s biggest mysteries. For a century, scientists have thought that the universe was expanding ...

But no one knows what dark energy actually is. One suggestion is that it might be a kind of energy associated with empty space known as the “ cosmological constant,” an idea first proposed by Albert ...

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is looking to create one of the largest maps of the universe by creating a catalog of Lyman-alpha-emitting galaxies. These galaxies, which ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have to use indirect evidence, like the explosions of Type Ia supernovae, to investigate the impacts of dark energy.
