Particularly, we argue that huge amount of energy could be produced as a result of matter-antimatter cold fusion. Crucial questions raised concerning the fate of particles and antiparticles produced by the big bang are addressed. Assumptions of possible existence of two kinds of gravity and masses of different signs are proposed. %K Matter-Antimatter Annihilation Energy %K Cold Fusion %K Big Bang Theory %K Antigravity %K Antiuniverse %K Theory of Multiverses %K Matter-Antimatter Chemistry %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=99333
