The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

Black holes form when an enormous mass collapses into an infinitesimal point known as a singularity. That compression creates such powerful gravity that nearby matter, particles and even photons are ...

Learn what a black hole is, how it forms, and how astronomers detect it. Understand the science behind black holes and their ...

The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

For years, dark matter has puzzled scientists, lurking in the universe’s vast expanse yet eluding direct detection. This ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively ...

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 ...

"It may take decades before we find out what really happens in black holes." Reports of the singularity's demise may have been premature. Earlier this year, new research suggested a potential solution ...

The early growth of the gas giant carved rings that formed primitive meteorites and shaped the architecture of the inner ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...
