"Study Suggests Elusive Planet Nine May Actually Be a Gravity Imposter"

A new study proposes that the elusive Planet Nine, theorized to exist in the outer reaches of the solar system, may not be a planet but rather evidence that gravity functions differently than previously thought. The researchers suggest that the gravitational anomalies observed in the outer solar system can be explained by applying an alternative concept of gravity known as modified Newtonian dynamics (MOND). MOND suggests that the strength of gravitational pull does not drop off as quickly at greater distances, which could explain the unusual orbits of objects in the Kuiper Belt. While MOND cannot explain all of the universe's missing mass, the study highlights the potential for the outer solar system to serve as a laboratory for testing gravity and studying fundamental problems of physics.
