A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...

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 ...

New research suggests an unseen 'mirror world' of particles that interacts with our world only via gravity that might be the key to solving a major puzzle in cosmology today -- the Hubble constant ...

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 ...

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.

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

Cosmology’s neat story of a universe driven apart by a simple, invisible “cosmic fuel” is starting to fray. A growing body of data suggests that dark energy, the ingredient thought to make up most of ...

New research looking at the cosmological constant problem suggests the expansion of the universe could be an illusion. When you purchase through links on our site, we may earn an affiliate commission.

Predictions of the rate of expansion of the universe based on the cosmic microwave background and standard model of cosmology do not agree with independent measurements based on supernovae. UC Davis ...
