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

For decades, cosmologists have had an awkward number sitting at the center of their equations. The universe is expanding, and ...

Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

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 ...

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

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

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 ...

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 ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.
