For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the universe’s accelerating expansion. Now a new wave of data is forcing ...

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 ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...

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.

The universe's expansion may be accelerating faster than previously thought. Dark energy, a mysterious force, might not be constant but could be changing over time. Multiple independent studies show ...

In the beginning, the Big Bang happened, sending everything in the universe expanding outward and apart, from a dense hot point. Since then, all that matter and energy has continued to move outward, ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark energy. This mysterious force drives the expansion of the universe to accelerate. Dark energy is an unknown ...

David Weinberg receives funding from the National Science Foundation and NASA that supports his dark energy research. Ashley Ross receives funding from Lawrence Berkeley National Lab to support his ...

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 ...
