Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

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 ...

We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean researchers suggests that dark ...

Researchers involved in the Dark Energy Survey (DES) have published their most comprehensive depiction to date of the Universe's expansion over the past six billion years in Physical Research D.

This enormous chain of hundreds of galaxies—a cosmic filament—is twisting through space 400 million light-years away ...

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.

The “horizon” he points to isn’t a doorway to the divine, other scientists say. Yet, modern physics has been trying to answer questions once left to religion.
