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

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

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

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

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

Why matter dominates over antimatter in our universe has long been a major cosmic mystery to physicists. A new finding by the ...

Mysterious dark matter makes up 85 percent of matter in the universe, and of the remaining 15 percent, scientists couldn’t account for half—until now.

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