In a new study published in Physical Review Letters, scientists have performed the first global simulations of monster shocks ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

For a generation, cosmologists have worked with a simple story: the universe is not only expanding, it is expanding faster ...

A recent study published in The Astrophysical Journal Letters has provided the most precise distance to the Coma Cluster of galaxies yet — and also has deepened a crisis in cosmology. The problem is ...

One of the most challenging problems in modern cosmology is the Hubble tension, a discrepancy in the predicted expansion rate of the Universe with different observational techniques that results in ...

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 ...

The final, formatted version of the article will be published soon. One of the most challenging problems in modern cosmology is the Hubble tension, a discrepancy in the predicted expansion rate of the ...

A new cosmological model suggests that the universe may not expand forever but instead collapse under its own gravity in a process mirroring the Big Bang in reverse. Our universe might not expand ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Our vast universe might not be infinitely expanding after all ...

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 ...

The story of the expanding Universe has been a back-and-forth one over the past 110 years: ever since general relativity was first introduced. Initially, Einstein introduced the notion of a ...
