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 ...

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.

Dark energy remains one of the most profound mysteries in modern physics. Since the discovery of accelerated cosmic expansion in the late 1990s, scientists have attributed this phenomenon to an ...

But the results of DESI’s latest analysis imply that the cosmic expansion is accelerating less now than it was in the past, which does not fit the assumption that dark energy is a cosmological ...

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.

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 clue ...
