In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

Researchers in Germany argue that a modified theory of gravity could explain universal expansion, removing dark energy from ...

Dark energy may be the most mysterious substance ever proposed, but many scientists are certain it exists. Why?

The Standard Model of our universe doesn’t match the evidence, in part because of dark energy, a ghostly force pushing the ...

Dark energy is one of the greatest mysteries of the universe. This mysterious force is thought to be accelerating the expansion of the cosmos. But a new study challenges this long-held belief. A team ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Scientists propose a new gravity theory using Friedmann equations. Their model explains the universe’s accelerating expansion ...

For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

Studies suggest that the universe's expansion is decelerating — but what could that mean for the future of the cosmos?

According to Professor Lee, if these results are confirmed, it could completely change our understanding of the universe's future.

An international consortium of scientists studying dark energy said Tuesday their three-dimensional map of the universe over 11 billion years suggested the cosmos wasn't steadily expanding, but acting ...
