Is There Hidden Force in Universe? Scientists Say It’s Possible
News Desk
Islamabad: Scientists are reigniting debate in the global physics community with a bold new idea: the possible existence of a mysterious “fifth force” that could reshape current understanding of the universe.
For decades, physics has been built around four fundamental forces, Gravity, Electromagnetism, Strong nuclear force, and Weak nuclear force, which together explain most observable phenomena.
However, researchers now argue that these forces may not fully account for how galaxies are arranged or why the universe continues to expand.
According to experts associated with NASA, investigating this possibility may require shifting focus closer to home. Instead of relying solely on distant cosmic observations, scientists suggest that crucial evidence could lie within our own solar system.
A major gap in current knowledge remains the nature of Dark matter and Dark energy, which together are believed to make up about 95 percent of the universe.

Despite their dominant presence, they have never been directly observed. Researchers propose that a fifth force could act as a missing link between this unseen matter and the visible universe of stars and planets.
Slava G. Tereshev has suggested a practical way to test the theory: by using highly precise laser measurements of the distance between the Earth and the Moon. If even a slight discrepancy is detected between observed results and predictions based on gravity alone, it could signal evidence of an additional force.
While large-scale missions such as Euclid are mapping billions of galaxies to better understand cosmic structure, scientists emphasize that controlled, high-precision experiments within the solar system may provide the most definitive answers.
The idea of a fifth force is not entirely new. In 2015, Hungarian researchers reported unusual results hinting at a possible new particle, later dubbed the X boson, which some theories link to an unknown force. More recent experimental findings that do not fully align with existing models have further fueled speculation.
According to physicist Tory Schiff, while observations on a cosmic scale are valuable, the decisive breakthrough will depend on precise, localized experiments.
If confirmed, the existence of a fifth force would mark a major turning point in physics, offering new insights into the Big Bang, the structure of the universe, and its ultimate fate.
