Researchers attempting to solve the problem of dark matter have proposed a particle that can travel to an unseen fifth dimension. The work is entirely hypothetical, as it attempts to explain a type of ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of time might be only part of a larger structure, with a hidden fifth ...

A team of German and Spanish scientists says they’ve found a “natural explanation” for dark matter and other unresolved scientific mysteries — but their work depends on the existence of a new ...

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 ...

For a long time, scientists have been chasing something they cannot see. It doesn’t glow, it doesn’t shine, and it never shows up in photos. Still, they are convinced it is everywhere. Some jokingly ...
