Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass. Because it’s so abundant, astronomers believe it should explain many unsolved ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery ...

One truly elegant hypothesis of physics is the "zero-energy universe" hypothesis. It proposes that the net sum of the energy in the universe perfectly equates to zero. According to the idea, if you ...

A research team led by Prof. Wang Jianjun from the Nanjing Institute of Geography and Limnology of the Chinese Academy of Sciences, has produced a global map depicting the distribution and variation ...

A new study suggests that dark matter may consist of particles with different masses. By introducing a two-component self-interacting dark matter model, the researchers show that both the low-density ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

Two fresh ideas are giving scientists new ways to think about how the universe’s hidden mass came to be. Together, they paint a richer picture of dark matter’s origins and how we might still discover ...

Galaxy clusters are the heaviest structures in the universe, yet most of their mass is invisible, inferred only from the way it tugs on light and galaxies. Now a new class of “dead” stars, white ...

Scientists have long suspected that a see-through substance known as dark matter suffuses the cosmos, keeping the fabric of our universe from tearing. But what exactly dark matter is made of remains a ...
