Scientists suggest dark matter may collide with itself, creating dense cores that could help solve three persistent mysteries ...

Six thousand eight hundred feet below the floor of an active nickel mine in northern Ontario, something has gone extremely cold. Not cold in the way of a walk-in freezer, or a liquid nitrogen tank, or ...

An almost invisible galaxy could crack open one of the biggest questions in cosmology ...

Cold dark matter theory holds that galaxies formed gradually in the early universe. So in accordance with CDM, astronomers always assumed that when we finally had the optical wherewithal—I want to say ...

Dark matter makes up roughly 85% of the stuff in our universe. It doesn’t glow, it doesn’t reflect light, and we can’t even see it. We only know it’s there because its massive gravity holds galaxies ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

After almost a year of searching, a high-tech instrument buried deep in a South Dakota cavern has turned up no sign of dark matter. Ironically, a team of physicists is pretty excited about it. After ...

We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature ...

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold ...
