This brings me back to my original question. I know that there is no proof that antimatter expresses an opposite gravitational force using exotic matter or whatever it might take. But on the other side, is there any proof that antimatter could absolutely NOT express an opposite gravitational...
Have there been Eotvos-type experiments using antimatter? I thought that because gravity is so much weaker than the electrical force, that this kind of experiment could only be done on an electically neutral mass like antihydrogen. I know that at CERN they have just begun to create...
If we define regular gravity as a warping of space in an 'down' direction, then the opposite gravitational force would warp it in the 'up' direction. I think that this would cause two antimatter masses to push away from each other. If this were true, then no antimatter stars could form, and...
Standard physics texts assert that antimatter expresses a normal attractive gravitational force. Has this been proven by any experiments, or only asseted in the current theories? We know from experiments that antimatter has the opposite charge, but could it also have the opposite gravitational...
