cosmology

Since 2014, there have been over 300 proposals for solutions to the "crisis in cosmology." None of these proposals is universally agreed upon by cosmologists, and the crisis just keeps getting worse.

Astrophysicists say our universe might be shaped like a three-dimensional donut, meaning you could point a spaceship in one direction and eventually return to where you started.

Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance could interact with itself in a higher dimensional universe.

Astronomer Wendy Freedman suggests that the latest observations of red giant stars could be closing the gap on the Hubble tension.

A big new sample of fast radio bursts is allowing scientists to ask big-picture questions about the cosmos.

The Dark Energy Survey just released its most comprehensive results. But did they really prove Einstein wrong?

If you'd like to "bake" a universe, you need two essential ingredients and one optional ingredient.

A team has offered a way for gravitational wave events called dark sirens to resolve a crisis in cosmology

An ultra-high-resolution simulation of a tiny slice of the universe — a million times smaller than a proton — has revealed the very first structures to ever exist.
