Race to uncover fifth fundamental force
Researchers based at the Paris Observatory led by Yu-Dai Tsai of the University of California and Luca Visinelli of the Tsung-Dao Lee Institute (TDLI), are using precise tracking data from near-Earth asteroids like Bennu to explore the possibility of a fifth fundamental force, which could reshape our understanding of gravity and the universe. This study began in 2022 with full findings expected to be published by 2025.
