Leading this quest is the Dark Energy Spectroscopic Instrument (DESI), a global collaboration involving over 70 institutions.

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 ...

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 ...

A new theory links gravity to quantum entropy and introduces the G-field, possibly explaining dark matter and cosmic ...

U.S. National Laboratories (Argonne, Lawrence Livermore, and Oak Ridge) possess three of the world’s fastest exascale ...

Instead, the amount of dark matter held steady through the breakneck cosmic expansion, surviving into the following epochs. So dark matter may have arisen before normal matter, but what does this ...

Today the canonical story of cosmic evolution describes this tug-of-war between the unwavering push of dark energy and the gravitational pull of matter (including the vast reservoirs of invisible ...

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.
