Astronomers have long described black holes as cosmic traps so powerful that nothing — not even a beam of light — can claw its way free. Yet even these extreme objects have limits, and scientists say ...

A new study suggests that decaying dark matter may have helped create the universe’s first supermassive black holes much ...

AMHERST, Mass. — In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere ...

A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing less than a billion years after the Big Bang. According to the standard theory ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from ...

Black holes formed before the Big Bang may still exist as cosmic fossils, offering new clues about dark matter and the origin of galaxies.

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

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.

Space-time is being driven apart. Every second that passes, the universe expands faster and faster. What is propelling this dramatic acceleration is an enigma, though – one scientists have known about ...

A supermassive black hole, ULAS J1120+0641, outgrows its galaxy and disrupts the cosmic balance, revealing a mystery of the ...
