The fate of the cosmos may be a bit different than previously expected. For years, scientists have talked about how the universe is always expanding — constantly moving outward, never stopping.

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

The end of the universe has always felt like a distant abstraction. But new calculations suggest that our original timeline might have been wildly optimistic. According to a team of Dutch scientists, ...
