Would some hypothetical negative mass-energy be repelled by gravity …

WebMay 24, 2024 · Luttinger observed that negative-mass objects would gravitationally repel all objects of any mass (positive or negative), while positive-mass objects would gravitationally attract all objects of any mass. That gives rise to the amusing scenario that a –5 kg object would repel a +5 kg object, while the +5 kg object would attract the –5 kg object. WebIn the case of negative mass, gravity can repel. It actually causes some really interesting and unintuitive behavior. Two objects with negative mass have the same sign of mass, … WebSince the gravitational force is proportional to the masses of the two objects, yes, a negative mass would be repelled by the gravity of a positive mass. HOWEVER! In accord with Newton’s Law (F=ma), matter with negative mass responds to any force by accelerating in the opposite direction. great wall buffet malvern ar

"The gravitational interaction of antimatter with matter or antimatter has not been observed by physicists. While the consensus among physicists is that gravity is expected to attract both matter and antimatter at the same rate that matter attracts matter, this is not experimentally confirmed.
