A surprisingly youthful estimate of the age of the rings has stirred a backlash.
Calculations involving a higher dimension are guiding physicists toward a misstep in Stephen Hawking’s legendary black hole analysis.
Three physicists stumbled across an unexpected relationship between some of the most ubiquitous objects in math.
