What if outer space isn’t empty, but behaves like a thick, slow-moving fluid? Anew study suggests just that, and it could help solve a puzzling mismatch between current models of the universe and ...

Here’s what you’ll learn when you read this story: A new paper adjusts an equation that defines our universe in response to recent new data. The cosmological constant, which describes how our universe ...

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn.

A trio of physicists play with the math that describes Bose Einstein condensates. Hidden down behind the BEC's couch, they found a fake cosmological constant that they could use to show why our ...

A physicist investigating black holes has found that, in an expanding universe, Einstein's equations require that the rate of the universe's expansion at the event horizon of every black hole must be ...

The original version of this story appeared in Quanta Magazine. Physicists have deduced subtle hints that the mysterious “dark” energy that drives the universe to expand faster and faster may be ...

An international collaboration of scientists has created the largest 3D map of our universe to date based on the first results from the Dark Energy Spectroscopic Instrument (DESI). It’s an impressive ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The widely accepted theory at the present moment ...

Scientists know very little about the mysterious force dubbed “Dark Energy” that seems to be quickening the expansion of the universe but, according to LSU Physics and Astronomy Associate Professor ...
