The universe isn’t just growing—it’s speeding up as it does. That discovery stunned scientists, upending long-held ideas about gravity and motion in space. This rapid expansion wasn’t predicted by ...

Wormholes sit at the edge of serious physics and science fiction, yet the math behind them is precise enough to suggest that spacetime itself could be riddled with hidden shortcuts. If such structures ...

In some ways, a wormhole might look like a black hole. And the wormhole would look like a sphere, not a hole. Einstein's theory of general relativity allows for the possibility of wormholes, but there ...

Scientists in Greece have laid out a mathematical framework to help explain a so-far-unsolved gap in our understanding of how gravity scales up to the full size of our universe. Specifically, ...
