In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not ...

Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how ...

Primordial black holes (PBHs) are hypothesised to have formed in the early Universe from the direct collapse of density fluctuations or phase-transition remnants. Unlike astrophysical black holes, ...

Dark matter decays could be the missing ingredient explaining how giant black holes formed before the first stars. A growing mystery in astronomy is the presence of gargantuan black holes—some ...

The team, which included Chandrachur Chakraborty and Sudip Bhattacharyya, proposed that neutron stars and white dwarfs can capture ultraheavy dark matter particles, which accumulate at their cores and ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.

We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia ...

The evidence for dark matter is everywhere and the evidence for dark matter is nothing. Galaxies rotate in ways that make no sense unless something invisible is adding mass. Light bends around galaxy ...

New research suggests that supermassive black holes that existed before the cosmos was 1 billion years old may have formed with a helping hand from dark matter, the universe's most mysterious stuff.

Famed author Douglas Adams described space as being "vastly, hugely, mind-bogglingly big." Space is also mind-bogglingly strange and mysterious. The cosmos is filled with unusual phenomena that ...

Dark matter may be primordial black holes from the Big Bang. David Kaiser explains. Dark matter remains one of physics' biggest open questions. MIT physicist David Kaiser joins Hakeem Oluseyi to ...

A new framework shows how hidden black hole “hair” could leave separate fingerprints in the frequency and fading of gravitational waves.
