Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

New research suggests time could hold the key to resolving mysteries of gravity, quantum mechanics, and other phenomena in ...

A team of physicists have proposed a new idea for uniting quantum mechanics and gravity, which they believe could explain the earliest moments of the universe. While interesting, and potentially even ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

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

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

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 ...

Laser light is injected into an optical cavity to continuously measure the position of a movable mirror. The output light is read out by homodyne detection, and the measurement data are analyzed using ...

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary University of London, proposes a new framework that could revolutionize our ...
