Physics

For the first time, researchers have created a scale model of the twisting loops of the sun’s magnetic field.

Tiny, dim “dwarf” galaxies have been found to hide gas-spewing black holes.

Three experiments have vetted quantum Darwinism, a theory that explains how quantum possibilities can give rise to objective, classical reality.

After an interstellar asteroid shot past the sun, scientists realized that there’s probably a lot of itinerant rocks out there.

Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.

A recent test has confirmed the predictions of quantum trajectory theory.

Lee Smolin’s radical idea to reimagine how we view the universe.

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.
