WASHINGTON (Reuters) - Scientists working in an international collaboration have tracked how the structure of the cosmos has grown over the past 11 billion years, providing the most precise test to ...

Scientists could be wrong about dark energy. But they’re right about gravity, a new study suggests. Dark energy, the mysterious phenomenon that causes the expansion of the cosmos to accelerate, is ...

Dark energy has been a mysterious element of cosmological equation since it was proposed three decades ago, but new research ...

In the wake of bombshell findings that suggest dark energy might be weakening as the universe expands, physicists are considering replacing the standard cosmological model of the universe with exotic ...

Effective Field Theory (EFT) has emerged as a unifying framework to describe the accelerated expansion of the universe and possible deviations from general relativity on cosmic scales. By organising ...

Our universe has been expanding ever since it was born in the Big Bang. For decades, most cosmologists believed the universe’s expansion was slowing. Gravity, pulling on all matter, would eventually ...

Gauss–Bonnet gravity introduces a curvature-squared invariant into the gravitational action, extending Einstein’s theory while preserving second-order field equations when coupled to a scalar field.

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a ...

There is growing controversy over recent evidence suggesting that a mysterious force known as dark energy might be changing in a way that challenges our current understanding of time and space. An ...
