‘Shocking’ results from a major astronomical study have raised doubts about the standard model of cosmology, forcing scientists to consider new ways of understanding dark energy and gravity ...

Lieu's improved model doesn't rely on exotic phenomena like "negative mass" or "negative density" to work. The theory offers instead the notion that the universe is expanding due to a series of ...

The chances of intelligent life emerging in our Universe -- and in any hypothetical ones beyond it -- can be estimated by a new theoretical model which has echoes of the famous Drake Equation.

There are two gold-standard methods for working out the Hubble constant — the value that quantifies the speed of the universe's expansion. The first is taken by measuring tiny fluctuations in ...

Researchers have developed a new model to calculate the chance of aliens' existence in our universe. The possibility of other lifeform civilizations likely depends on how dark matter forms.

The universe may be dying much faster than we thought One idea is known as holographic dark energy. In this scenario, gravity — and space itself — is an illusion.

Space Best ever map of early universe is double-edged sword for cosmologists. The finest ever map of the cosmic microwave background - the faint evidence of the universe's early form - has yielded ...

He's a member of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), is studying dark energy from an earlier time in the universe's existence than DESI.HETDEX is also focused on sound ...

We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the ...

The standard model of cosmology struggles to explain all the observations when taken together—but a model where dark energy’s influence changes over time seems to fit the data well. The standard model ...

The new model forgoes the need for either dark matter or dark energy as explanations for the universe's acceleration and how structures like galaxies are generated.. The researcher's work builds ...
