A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where a particle does not have a single definite value of position or momentum ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

A new study suggests that certain 'quantum collapse models'—which posit that wavefunction collapse happens spontaneously—could be tied to gravity, introducing a tiny intrinsic uncertainty in time ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

Two recent studies explore whether time can exist in quantum superposition and how gravity might affect its measurement. One proposes using advanced ion clocks to detect quantum states of time, while ...
