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.
In a world seemingly filled with chaos, physicists have discovered new forms of synchronization and are learning how to predict and control them.
No new particles have been found at the Large Hadron Collider since the Higgs boson in 2012, but physicists say there’s much we can still learn from the Higgs itself.
A state-of-the-art supercomputer simulation indicates that a feedback loop between global warming and cloud loss can push Earth’s climate past a disastrous tipping point in as little as a century.
