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 ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Oftentimes, we think of as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of as something separate, a steady ticking that ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...
