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

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

Anaxagoras, a visionary Greek philosopher, foresaw concepts of expanding universe and multiple worlds centuries before modern science.

Suppose the birth of the universe was not a definite start, but a cosmological rebound far within a black hole? This radical idea has been picking up steam as new theoretical research, spearheaded by ...

Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

Dark energy, the mysterious force driving the accelerated expansion of the universe, has puzzled scientists since its discovery in 1998. Despite its elusive nature, dark energy is believed to ...

The standard explanation has been dark energy, an invisible force added into the equations to make the math work. But now, an ...

A new Utah Valley University study is providing new evidence in a debate astronomers across the world haven’t been able to agree on — how fast the universe is expanding. The findings may add more fuel ...

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

(CNN) — The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

In this mosaic image stretching 340 light-years across, Webb’s Near-Infrared Camera (NIRCam) displays the Tarantula Nebula star-forming region in a new light, including tens of thousands of ...
