Dark Matter experiment is a large research effort involving over 200 scientists and engineers at 40 institutions worldwide.

Galaxies are not islands in the cosmos. While globally the universe expands—driven by the mysterious "dark energy"—locally, ...

The enigmatic idea of dark energy has consistently been referenced to explain the universe’s expansion, but new research may upend years of cosmological beliefs with a shocking claim made by ...

"Up to this year, most observations were consistent, with dark energy being the cosmological constant. Nonetheless, 2024 was full of hints pointing out this might not be the case." 2024 was a big ...

New research suggests dark energy might not be real, proposing instead that the Universe’s apparent acceleration is due to its patchy structure. Upcoming observations from space missions could prove ...

Dec. 20, 2024 — One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding.

Dark energy — an unknown energy source that is causing our Universe’s expansion to accelerate – doesn’t actually exist, according to new research. Dark energy is commonly thought to be a weak ...

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing theory known ...

Scientists challenge the existence of dark energy. They suggest the universe's accelerating expansion is due to uneven gravitational effects on time. This new theory, called the "timescape" model ...

It also raised the question of what was causing this acceleration. Cosmologists eventually decided that the expansion was being driven by a force they called dark energy and began to develop a ...
