In simplest terms, the rate at which the universe expands on paper doesn’t match actual astronomical observations. That speed ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding?

A slowly spinning universe could resolve a puzzle in physics known as the Hubble tension, a new model suggests.

A new study suggests the universe may rotate -- just extremely slowly. The finding could help solve one of astronomy's biggest puzzles.

The rotating model, which does not break any known law of physics, suggests the universe could spin around once every 500 billion years. This would be far too slowly to detect easily, but enough to ...

A new idea about cosmic expansion has emerged that might remove the need for dark matter and dark energy altogether.

Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...

Now, people who own a 2025 Neo QLED 8K, 4K, or QLED TV can choose from hundreds of pieces of artwork to display when they’re ...

But it doesn’t explain the so-called “Hubble tension”—a long-standing disagreement between two ways of measuring how fast the universe is expanding. One method looks at distant exploding ...
