Of all the sciences, physics is unique in that it can come to a broad consensus with math alone—very little tactile evidence required. Never has this been the case more than with dark matter. Though ...

Welcome to the age of precision cosmology, a scientific era in which astronomers and physicists have measured almost everything about our universe—except for its deepest mysteries: dark matter and ...

After decades of hunting, physicists still don’t know what makes up most of the universe’s matter. Now they need to cast a wider net.

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 ...

An observatory in Chile is taking a timelapse of the sky over the Southern Hemisphere to help scientists measure the ...

For a while now, there has been a problematic mystery at the heart of the standard cosmological model. Although all observations support the expanding universe model, observations of the early period ...

Models giving dark matter more complex behavior could help solve multiple cosmic mysteries Did the very young universe make swarms of tiny black holes? Astronomers puzzled out minuscule distortions in ...

Dark matter makes up most of the mass in galaxies and galaxy clusters. In fact, scientists estimate that ordinary matter makes up only about 5% of the universe, while dark matter makes up about 27%.

There is a lot of matter in our galaxy that we can’t see. It’s called dark matter. Have you ever looked up at the night sky and thought it looks like a lot of empty space? Turns out, it’s not empty ...
