A project to map galaxies across the universe may have spied cracks in the foundation of our understanding of the cosmos.

New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.

Dark energy makes up roughly 70 percent of the universe, yet we know nothing about it. Around 25 percent of the universe is the equally mysterious dark matter, leaving just five percent for everything ...
