While probing the dawn of the universe for the origins of ancient galaxies, the James Webb Space Telescope uncovered something unexpected lurking at their cores—a discovery that might reshape our view ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.

To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in the sky. But no one knows whether the ...
