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 ...

The big thinkers at Aperture explain dark energy and its role in filling the void of space.

Astronomers use the term dark energy to refer to energy in the universe that is unaccounted for by ordinary matter but necessary to explain cosmology. Astronomy, however, isn't the only field with ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

A physicist proposes that the universe might not be empty but act like a viscous fluid, resisting expansion. This bold idea ...

Today we are going to talk about cosmology and the fact that black holes were considered as an almost unbelievable idea. In the 30s, British astronomer Arthur ...

For decades, dark energy has been used to explain why the universe is expanding faster and faster. But new observations are revealing cracks in that explanation. Recent data suggests dark energy may ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...

Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is ...

Particle never before seen on Earth detected; it could come from a primordial black hole and the origin of the universe.

NASA’s Nancy Grace Roman Space Telescope will conduct a wide-area survey to study dark matter, dark energy, and the expansion of the universe across 11 billion light-years.
