Dev says that if the incoming particle was dark matter and not a neutrino, it could explain this mystery. The shallow predicted path of the incoming particle meant that it had to travel through ...

Known for its large mass despite emitting very little light, Segue 1 is traditionally viewed as a prime candidate for studying dark matter-dominated galaxies. However, the unique investigation ...

Dark matter affects how stars move within galaxies, how galaxies build up over time, and how everything in the universe is held together—but no existing tool has directly detected it. While dark ...

Dark matter, which is thought to constitute the majority of all matter, does not reflect, absorb, or emit light. But it does have mass, which means it generates gravity and can cause gravitational ...

Dark Matter coverage from Scientific American, featuring news and articles about advances in the field.

They needed some extra mass to hold them together. Observations and simulations combined, astronomers knew they needed to rethink how the universe worked, and slowly the idea of dark matter took hold.

As Trump reveals too much about his mass deportations, badly undermining Stephen Miller’s goals, a progressive strategist discusses new data showing the MAGA coalition coming under serious strain.

We can't see dark matter, but scientists have made the largest map yet of the invisible material that helps make up the universe. Researchers used a dark energy camera and a large telescope to ...

Dark matter is already weird — invisible, untouchable, and seemingly everywhere. However, scientists are now asking if it might be even stranger than we thought. What if, instead of just ...
