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

The newest findings include data on more than double the cosmic objects that were surveyed and presented less than a year ago. Those 2024 revelations first hinted at how dark energy may be evolving.

Cosmic Tug-of-War Around a century ago scientists began to realize that the universe is expanding outward from what they now call the big bang, the explosion of energy that birthed space and time.

This phenomenon, known as cosmic shear, can provide clues about the role of dark energy in shaping the universe. With this model, they transformed simulated shear data from specific points into ...

"In principle, extraction is possible, and it could be a clean and efficient solution to the complex energy problems we will likely face as a society in the distant future" Humans are quite ...

Measurements of the faint afterglow of the Big Bang (known as the cosmic microwave background) are also important. They do not directly measure dark energy or how it evolves, but they provide ...
