It shapes galaxies and bends light, but is dark matter even real? Find out what scientists know, what they’re still guessing, and why this mystery matters.

Dark matter is more than five times as abundant as all the visible matter in the universe. So why can't we see any of it?

Besides particles like sterile neutrinos, axions and weakly interacting massive particles (WIMPs), a leading candidate for ...

Dark matter, though invisible, weighs heavily on how we understand the universe. Its gravity sculpts galaxies, holds clusters together, and shapes cosmic evolution—yet we still don’t know what ...

First and perhaps most perplexingly, researchers remain unsure about what exactly dark matter is. Originally, some scientists conjectured that the missing mass in the universe was made up of small ...

The detection of dark matter, an elusive form of matter believed to account for most of the universe's mass, remains a long-standing goal within the physics research community. As this type of ...

Evidence suggests that we are suspended in a cosmic sea of dark matter, a mysterious substance that shapes galaxies and large structures in the universe but is transparent to photons, the carriers ...

The latest hunt for dark matter has come up empty handed so far, but the upside is that physicists can now set the tightest constraints ever on the nature of this mysterious substance. New ...

Does dark matter interact with itself? The answer may lie in vast clusters of colliding galaxies. Dark matter is notoriously antisocial, refusing to interact with light and "normal" matter ...

The rest is composed of two invisible, enigmatic entities: dark matter and dark energy. Together they govern the behavior of the universe. Evidence for dark matter has been accumulating for 50 years.

is dark matter. Dark matter emits no light and scientists only know it exists because, when they look into the night sky, they see galaxies rotating a lot faster than they should. The laws of ...

When wading into the murky realm of theoretical physics, one of the more difficult concepts for scientists to explain is that of dark matter. It’s the invisible form of matter constantly eluding ...
