In recent years, a group of Hungarian researchers have made headlines with a bold claim. They say they’ve discovered a new particle — dubbed X17 — that requires the existence of a fifth force of ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same ...

Researchers may be on the brink of discovering evidence of a fifth fundamental force. As far as we know, at the most basic level, the universe is made up of fundamental particles and controlled by ...

There may be a fifth fundamental force of the universe that we haven’t documented yet — and, according to new research, our best bet of uncovering it may not lie in deep space, but in objects ...

Part one of a four part series on the fundamental forces (or interactions) of physics begins with the strong force or strong ...

Some physicists believe that a fifth fundamental force could be the cause of some observational anomalies. A study is investigating ways to closely examine the trajectories of well-documented ...
