Maybe, as you say, it's a new dimension. One of the other popular idea is that the theory known as supersymmetry. It basically tells us that every subatomic particle has a partner.

Whether as the protons and neutrons that help form chemical elements, the photons that we perceive as light or even the flows ...

Scientists have observed anyons -- quasiparticles that differ from the familiar fermions and bosons -- in a one-dimensional quantum system for the first time. The results may contribute to a ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted ...

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. Scientists ...
