samtheflash82 Posted March 22, 2009 Posted March 22, 2009 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?
swansont Posted March 22, 2009 Posted March 22, 2009 It's not antimatter, as such, that you are proposing, since antimatter is a term already in use and has a positive mass.

coke Posted March 25, 2009 Posted March 25, 2009 i remember reading something in popsci about gravitons which are their own antimatter. (graviton = antigraviton)... i think they repel against matter.

cameron marical Posted March 25, 2009 Posted March 25, 2009 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?
antimatter Posted March 30, 2009 Posted March 30, 2009 do you think there could be a negative mass such as sort of going past a singularity? 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!)
