You have lots of ways of thinking about space. Some of these ways help you to judge the relative location of things over very large distances. For example, you can easily judge that New York City is ...

Noncommutative geometry offers a radical reformulation of traditional geometrical concepts by replacing the classical notion of a manifold with a noncommutative algebra of coordinates. This approach ...

Physicists have long treated mass as a basic ingredient of nature, something particles simply possess, even as the Higgs mechanism explained only part of the story. A new wave of theoretical work now ...

Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible field, but from the hidden geometry of space itself. Instead of treating extra ...

Geometric analysis in Minkowski space offers a robust framework for understanding the interplay between the curvature of trajectories and the dynamic behaviour of fields, particularly within the ...

Like cosmic lighthouses sweeping the universe with bursts of energy, pulsars have fascinated and baffled astronomers since they were first discovered 50 years ago. In two studies, international teams ...

The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental physics. The very structure of spacetime might underlie every interaction in ...

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...
