How the universe will end is an ongoing debate among cosmologists, and outcomes vary depending on specific theories. A new paper analyzes the end of the universe in relation to a theory known as ...

Estimates of how fast the universe is expanding disagree. Could a new form of dark energy resolve the problem?

For nearly 10 years we’ve been operating in a search mode, and any day we could make a discovery,” said Gray Rybka, a ...

Is it far-fetched? Of course! But right now, cosmologists are trying to figure out if there’s a group of multiple universes running parallel to each other—and whether they might be habitable.

On a mountain in northern Chile, scientists are carefully assembling the intricate components of the NSF–DOE Vera C. Rubin ...

These axions could form an explanation for the elusive dark matter that cosmologists search for -- and moreover, they might not be too difficult to observe. A team of physicists from the ...
