Calculations involving a higher dimension are guiding physicists toward a misstep in Stephen Hawking’s legendary black hole analysis.

Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.

The renowned physicist Leonard Susskind has identified a possible quantum origin for the ever-growing volume of black holes.

String theorists elide a paradox about black holes by extinguishing the walls of fire feared to surround them.

The renowned British physicist, who died at 76, left behind a riddle that could eventually lead his successors to the theory of quantum gravity.

Physicists theorize that a new “traversable” kind of wormhole could resolve a baffling paradox and rescue information that falls into black holes.

Can a fluid analogue of a black hole point physicists toward the theory of quantum gravity, or is it a red herring?

The physicist-mathematician Miranda Cheng is working to harness a mysterious connection between string theory, algebra and number theory.
