New quantum theory of gravity brings long-sought 'theory of everything' a crucial step closer

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the goal of generations ...

Colors are objective, according to two philosophers—even though the blue you see doesn't match what I see

Is your green my green? Probably not. What appears as pure green to me will likely look a bit yellowish or blueish to you. This is because visual systems vary from person to person. Moreover, an object's color may appear ...

Âé¶¹ÒùÔºicists test quantum theory with atomic nuclei from a nuclear reaction

Many atomic nuclei have a magnetic field similar to that of Earth. However, directly at the surface of a heavy nucleus such as lead or bismuth, it is trillions of times stronger than Earth's field and more comparable to that ...

30-year mystery of dissonance in the 'ringing' of black holes explained

A scientist from Tokyo Metropolitan University has solved the longstanding problem of a "dissonance" in gravitational waves emitted by a black hole.

New framework suggests stars dissolve into neutrons to forge heavy elements

Understanding the origin of heavy elements on the periodic table is one of the most challenging open problems in all of physics. In the search for conditions suitable for these elements via "nucleosynthesis," a Los Alamos ...

New quantum optics theory proposes that classical interference arises from bright and dark states of light

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In contrast, quantum mechanics ...
