Probing the Strong Equivalence Principle through the External Field Effect. How Do Two Masses Fall?
Ankit Kumar, Kelvin Tang Tee Tniam, Peng Chengxiaohe +5
Despite compelling evidence, the absence of a confirmed dark matter particle has sustained interest in modified gravity as an alternative explanation for the observed phenomenology…
