OK, NERD OUT TIME!

I am making a mod for Kerbal Space Program that will have enormous spaceship parts, and this is.. err.. the smallest part at just 1.25m in diameter. it does contain 1.5t of anti-carbon... like... antimatter..

Anyways this tiny thing beats all nuclear weapons on earth combined... about six times over..
thats how stupidly dangerous antimatter is..
And it will be used as a fuel!

Or this tank could contain anti-osmium with a density of 22,500kg/m3, and have over 15t in this tiny volume!

Antimatter in KSP would require a 5x10m cylindrical tank to just hold 1.5t of antimatter, and this is dense.. or with osmium, stupidly dense.
