Researchers hypothesize a fifth force of nature that could explain the intricate relationship between dark matter and dark energy, suggesting a revolutionary expansion of the Standard Model of physics.

Could a new, fifth force of nature help answer some of the biggest mysteries about dark matter and dark energy? Scientists are actively exploring the possibility.

The Standard Model of physics is widely regarded as one of the greatest achievements in modern science. It describes the universe’s four known forces — gravity, electromagnetism, and the strong and weak nuclear forces — as well as a diverse array of fundamental particles and their interactions. By many measures, it stands as one of the most successful scientific theories in history.
