When we develop antimatter antennas, we will see that the space between galaxies is actually replete with antimatter.We have developed antimatter. We use it every day. PET scans, for example: Positron Emission Tomography. Positrons are positively charged electrons, i.e. antimatter. In a nuclear weapon you take an atom and you split it, and the two halves you end up with have less mass than their sum did. That difference of mass becomes pure energy and is released as heat, light, a blast wave, etc..That's what E=MC^2 refers to. The energy contained in a given object is equal to the mass of the object times the speed of light squared; E is the absolute maximum amount of energy you'll get if you convert the entire mass to pure energy. When matter and antimatter collide, they annihilate each other and both masses become pure energy. So given that, I'm not sure what makes you think the space between galaxies is full of antimatter...
