A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.
Researchers have confirmed rumors of a black hole collision that challenges our ideas about how black holes form.
New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.
A new look at a ubiquitous phenomenon has uncovered unexpected fractal behavior that could give us clues about the early universe and the arrow of time.
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.
A recent challenge to Stephen Hawking’s biggest idea — about how the universe might have come from nothing — has cosmologists choosing sides.
The sun radiates far more high-frequency light than expected, raising questions about unknown features of the sun’s magnetic field and the possibility of even more exotic physics.
