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

A paper published in 2024 theorizes that time may have existed before the Big Bang, but we're still not entirely sure.

Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model ...

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

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

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

A new study in Monthly Notices of the Royal Astronomical Society by researchers including István Szapudi of the University of ...

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 ...

Could the universe be rotating? Discover how this theory may solve the Hubble tension in modern cosmology and physics.

A faint cosmic spin – one rotation per 500 billion years – could resolve the stubborn Hubble tension by tweaking standard ...

An extremely bold hypothesis proposes transient temporal singularities remove the need for dark matter and dark energy.
