An artist's impression of gravitational waves (red and blue) emitted by a merging pair of black holes, inside a cloud of dark ...

There’s still a lot we don’t know about dark matter, or the “missing” mass supposedly constituting around 85% of the universe. Physicists have good reason to believe it’s out there. New research ...

Modern cosmology assumes dark matter exists. But what makes us so certain that dark matter is the answer—and what if we're wrong?

A new study in the journal Nature examines the distribution of dark matter in the universe, attempting to figure out if it obeys the same laws as regular matter. What it found suggests that dark ...

In the vast universe, galaxies rotate in ways that don’t make sense if only visible matter is considered. For almost a century, scientists have tried to explain this by searching for a hidden force ...

Dark matter is a hypothetical form of matter that is implied by gravitational effects that can't be explained by general relativity unless more matter is present in the universe than can be seen. It ...

Newton’s Law of Gravity just survived its biggest cosmic test. Scientists studied nearly 686,000 galaxies spread across 7 billion light-years. The result surprised even modern cosmologists. Gravity ...
