In modern physics, gravity is no longer understood as a force pulling objects together. It is the bending of spacetime itself ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Physicists have directly mapped a hidden kind of geometry inside quantum materials that steers electrons in ways strikingly ...

The second paper, "Fermion Chirality from Non-Bipartite Topology," applies this same lattice geometry to the quantum world. It proposes that the "handedness" (chirality) of subatomic particles is not ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Abstract: Attitude and size estimation of satellite targets is crucial for space surveillance. Existing methods that utilize radar or optical images from ground-based sensors typically rely on the ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting “spacetime fluctuations” - tiny, random distortions in the fabric of spacetime that ...
