The universe is expanding at an accelerated rate and our current best theories to explain this is a mysterious form of energy called "dark energy" that by its very existence is pushing the universe to ...

Recent surveys hint that the rate of cosmic expansion changes dramatically over time; if that's true, then the universe could ...

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 ...

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 ...

Over ten years ago, the Dark Energy Survey (DES) began mapping the universe to find evidence that could help us understand the nature of the mysterious phenomenon known as dark energy. I'm one of more ...

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 ...

A new study suggests the universe may end in a 'Big Crunch' just 33.3 billion years from now, far sooner than the trillions of years once expected. Using data from the Dark Energy Survey and the Dark ...

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 ...

In the late 1990s, two teams of astronomers were out to settle a score. Cosmologists had been at odds for over a decade in their quest to measure the total amount of matter and energy in the universe.

Here’s what you’ll learn when you read this story: Scientists have recently used an updated understanding of the math of our universe to theorize that the universe will end in a crunch rather than ...
