Galaxies are not islands in the cosmos. While globally the universe expands—driven by the mysterious "dark energy"—locally, galaxies cluster through gravitational interactions, forming the ...

"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 ...

Groundbreaking new findings are challenging the existence of dark energy, based on research that suggests the uneven structure of the universe could provide an alternate explanation for its ...

Dark energy and dark matter refers to the unseen energy and matter components of the Universe. Dark matter is invisible, non-baryonic matter hypothesized to explain phenomena including ...

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.

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 ...

The evolution of the Universe as we know it. Credit: NASA. Dark energy is central to our modern understanding of cosmology. In the standard model, dark energy is what drives the expansion of the ...

Dark energy does not exist, some scientists have claimed – which could help get rid of one of the universe’s biggest mysteries. For a century, scientists have thought that the universe was ...

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 ...

Dark energy is just a substance ... He’s upfront about challenges to this idea as well as possible solutions. While the cosmologically coupled black holes hypothesis has observational backing ...
