The universe is expanding at an accelerating rate—or is it?

Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace.

Smoking-gun evidence for modified gravity at low acceleration from Gaia observations of wide binary stars

A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred ...

Explaining the accelerating expansion of the universe without dark energy

Enigmatic 'dark energy', thought to make up 68% of the universe, may not exist at all, according to a Hungarian-American team. The researchers believe that standard models of the universe fail to take account of its changing ...

New research suggests that our universe has no dark matter

The current theoretical model for the composition of the universe is that it's made of normal matter, dark energy and dark matter. A new University of Ottawa study challenges this.

How do oceans start to close? New study suggests the Atlantic may 'soon' enter its declining phase

A new study, resorting to computational models, predicts that a subduction zone currently below the Gibraltar Strait will propagate further inside the Atlantic and contribute to forming an Atlantic subduction system—an ...

Accelerating melt rate makes Greenland Ice Sheet world's largest 'dam'

Researchers have observed extremely high rates of melting at the bottom of the Greenland Ice Sheet, caused by huge quantities of meltwater falling from the surface to the base. As the meltwater falls, energy is converted ...

Researchers use supercomputer to determine whether 'molecules of life' can be formed naturally in right conditions

Basic biology textbooks will tell you that all life on Earth is built from four types of molecules: proteins, carbohydrates, lipids, and nucleic acids. And each group is vital for every living organism.
