Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

This tension between Being and Becoming was recorded in early Greek philosophy. Parmenides presented reality as timeless, unified and changeless — the true Being admits no coming-to-being or ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some ...

The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle ...

This article was originally published by Knowable Magazine. Rod Serling knew all about dimensions. His Twilight Zone was a dimension of imagination, a dimension of sight and sound and mind, a ...
