When two black holes slam together, they do not simply vanish into darkness, they ring like struck bells and briefly light up ...

According to the theory, our reality is encoded on the boundary of a black hole within a much larger universe.

"It boggles the mind! The forces that are needed to dislodge such a massive black hole from its home are enormous. And yet, ...

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 ...

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at ...

Mysterious ‘little red dots’ seen by the James Webb Space Telescope can be explained by a new kind of black hole enshrouded ...

Astronomers usually detect black holes by looking for X-rays. When gas and dust fall toward a black hole, they heat up and ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

In December 2019, an ordinary galaxy 300 million light-years from us in the constellation Virgo suddenly woke up. After decades of inactivity, the black hole at the galaxy's heart burst with light.

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...
