so this is a hypothesis i had concerning gravity and so called antigravity. it is my understanding that every object with any mass has a gravitational pull. it seems that for any type of true antigravity, an object would need to have a negative amount of mass. this of course seems impossible but then i started thinking about it more and thought of an interesting idea that involves antimatter. im not exactly sure how antimatter works but it seems that since mass is the amount of matter an object has, would an amount of antimatter mean that you had negative, or "antimass?" if you would get a type of "antimass" wouldnt that generate a force that was opposite that of gravity? if this works could we harness this "antigravity" without the antimatter and normal matter annihilating each other?

It's not antimatter, as such, that you are proposing, since antimatter is a term already in use and has a positive mass.

thats basically what i was wondering about with antimatter. i guess since anti matter does have positive mass, that youre right. do you think there could be a negative mass such as sort of going past a singularity?

i remember reading something in popsci about gravitons which are their own antimatter. (graviton = antigraviton)... i think they repel against matter.

They are the same particle, but that does not make them repel.

it sounds to me like something that could be considered to be like this antigravity could be the end of a wormhole. it brings things out of what seems to be nothing. like antigravity would do. except not bringing things out, just kind of bending space in the opposite direction. it couldnt have mass then, could it?

Does going past a singularity give you a negative mass? I thought that once you passed the event horizon, you were just shredded to pieces by the gravitational pull. (I'm not trying to prove you wrong, I really don't know!)
