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 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.
