and if there wasn't than nothing would exist.

Not necessarily, if matter and antimatter was seperate upon creation so there are galaxies of matter and galaxies of antimatter then they could exist, as long as they never came in contact with each other.

Question: do I take it that the m in E=mc^2 is either anti matter or matter? or is this sposed to be just a very simple idea of the amount of energy it takes to make matter and not the process or by products of it being made?

E=mc^2 applies to both matter and antimatter.

Antimmatter has mass too.

 

It takes 1.022MeV of energy to make an electron and positron pair. Half of the energy becomes the mass of the electron and the other half becomes the mass of the positron.

that clears that up, thanks.

All I can say is wow. This is amazing stuff and mankind is really kickin butt^_^

Klaynos asked how we would store anti particles. A somewhat cheap, easy and realistic method would be to have a vaccum, surrounded in equal magnetic/electric field, as to keep the particle in the centre. If you wish to go out of so realistic, then you could have the magnetic/electric field constantly going in circles as to keep the Charged antiparticles going in circles and not making contact with matter.

I wonder if a vacume is the oposite of matter or if there is anti-space.

Storage methods described by Ragib (or similar methods) are known as Penning traps and Paul traps.

A vaccum is where there is no matter, Not the opposite of matter. That would make a vaccum and anti-matter the same thing. Space is a diemension, any "anti-diemenson" would not been as seen an anti diemension but just an additional one.
