Abstract

Astronomers have been searching for a hypothetical "Planet Nine" on the outskirts of our solar system for eight years. The existence of this planet has been inferred from the unusual clustering of asteroids in the Kuiper Belt. However, two researchers have proposed an alternative theory called Modified Newtonian Dynamics (MOND) that can explain the strange orbits of these asteroids without the need for Planet Nine. MOND suggests that gravitational forces deviate from the predictions of Newton and Einstein, and if it is correct, dark matter does not exist. Further observations will be needed to determine which theory is correct. [Extracted from the article]
