A model of the cyclic universe suggests that dark matter could be a population of black holes predating the Big Bang.

No theory could explain the slight excess of far-ultraviolet light in the Milky Way until now.

Generally speaking, black holes are regions of spacetime where matter is compressed into a tiny space. Dark matter, meanwhile ...

Two kilometres underground near Sudbury, Ont. , a machine has reached a temperature so low it barely seems real.

In a study published this week in Physical Review Letters, an international team of astronomers tested cosmic observations ...

A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing ...

A dark matter signal that appears in one place but not another might look like a contradiction. This new study argues it may ...

A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.

First and perhaps most perplexingly, researchers remain unsure about what exactly dark matter is. Originally, some scientists ...

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology ...
