For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark ...

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 ...

He came up with a new one, called the Late-Transition Interacting Thawer (LTIT) model, which models how dark energy could "thaw" after a certain amount of time after the universe started and is slowly ...

Two-sigma things happen all the time. But three sigma I’m listening now. Dragan Huterer Dark energy has been the most ...

A small, seemingly technical assumption baked into the way astronomers standardize Type Ia supernovae may be responsible for the growing tension between different measurements of dark energy. New data ...

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 ...

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 ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole? The universe seems to be rotating, and if ...

Our universe does host life, but another one might be even better suited for life. Here’s what you’ll learn when you read ...

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