Quantum gravity challenges the classical notion of spacetime by positing that the smooth, continuous fabric described by general relativity may arise from more fundamental, non-spatiotemporal entities ...

The researchers extended existing theoretical models to account for quantum fluctuations and applied these models to flowing condensates, discovering stable density and velocity fluctuation patterns ...

Recently, research teams from Kyoto University and the University of Tokyo developed a novel mathematical framework that utilizes modern amplitude techniques to analyze black hole radiation and ...

In their study, Zhao and Smalyukh created a space–time crystal in the nematic phase of a liquid crystal. In this phase the crystal’s rod-like molecules align parallel to each other and also flow like ...

Hoboken, N.J., July 14, 2025 — Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

SPACE-TIME may not be fundamental. Instead, according to the holographic principle, it emerges from something deeper, like a 3D hologram emerges from a flat surface. The principle says that space-time ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a ...

Seeking endorsements for her new book, Chanda Prescod-Weinstein finds herself staring at fundamental questions of space, time ...

This is a preview. Log in through your library . Abstract Classical field theory is about fields and how they behave in space–time. Quantum field theory, in practice, usually seems to be about ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...
