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 ...

The supermassive black hole at the center of our galaxy, Sagittarius A*, is spinning rapidly and altering space-time around it, a new study has found. Space-time is the four-dimensional continuum ...

Their conclusion, which comes from considering the behaviour of qubits, questions the now-dominant idea that four-dimensional space-time is the fundamental fabric of physical reality.

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 ...

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 ...

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 ...

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