Dark energy is believed to have a negative impact on big structures, limiting the formation of such particles.

Contrary to earlier understandings based on Einstein’s theory of general relativity, research from the University of Michigan has now found that the pace of growth of these substantial structures is slower than expected.

Large cosmic structures are predicted to expand at a certain rate as the universe expands, with galaxy clusters and other dense areas expanding faster than empty space.

A look into the anatomy of these structures shows that our cosmos is woven with galaxies like a vast cosmic spider web. They are not distributed randomly. Instead, they assemble in groups. In reality, the early universe’s cosmic web began as small aggregates of matter that later developed into individual galaxies, galactic clusters, and filaments.

Atomic clocks are the most accurate timekeeping instruments we have. A new study proposes a way to use the instruments’ mind-blowing level of precision to detect the tiniest of energy fluctuations, potentially giving scientists a way to observe some types of dark matter.

Dark matter continues to prove elusive: though we haven’t observed it directly, we can see its effects on the Universe. Frustratingly, there is nothing in our current models of physics to explain what we see.

Here, researchers from the University of Sussex and the National Physical Laboratory in the UK have suggested using atomic clocks to detect certain low-mass particles theorized to potentially make up this mysterious material.
