Korean scientists studying Type Ia supernovae have found strong evidence that the universe's expansion is not accelerating, ...

The expansion of the universe is already confusing and controversial, with researchers unclear exactly how fast it is going ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...

As if dark energy weren't already mysterious and baffling enough, new research suggests that this unknown force may not be ...

A remarkable new study challenges the findings of Nobel Prize winning research into how our universe has changed over time.

For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates were the use of standard candles, celestial events of the same luminosity ...

Archaeologists have uncovered evidence of a ritual-based site that may have been built long before the rise of Maya rulers ...

A team led by UNIGE has shown that the most mysterious component of our Universe follows the laws of classical physics, though some doubts still remain. Does dark matter obey the same physical laws as ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

We measure the “warmness” of the dark matter, i.e. the comoving root-mean-square thermal velocity v hrms (1) , with nearly 3000 spiral galaxy rotation curves in the ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period ...
