The astronomers Michel Mayor and Didier Queloz won half of the prize for their 1995 discovery of a Jupiter-like planet orbiting a nearby star. The cosmologist James Peebles won the other half for work exploring the structure of the universe.
A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.
New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.
Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.
Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.
