It's sometimes written that our Universe is 3+1 dimensional instead of 4-dimensional because time is on a slightly separate footing: increasing your motion through space decreases your motion ...

What happens when the very fabric of space-time breaks down? In this video, we explore one of the deepest mysteries of modern physics, the idea that the Universe, as we know it, may have emerged from ...

We experience time passing, irrespective of what we do, in a way we don’t for the dimensions of space, and therefore intuitively consider it something quite different. So it was a shock when ...

Essentially, this 4D space-time crystal would consist of a physical object with regular periodic atoms that are moving in a regular, periodic pattern. They would move forever — and with no ...

Known as Dimensional Regularization, it consists of defining the theory in a space-time that has more than four dimensions.

Here the authors report the distribution of high-dimensional polarization and energy-time entangled photons via a 1.2 km-long free-space link.

For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An ...
