Supposedly this is a result of a combination of General Relativity (GR) and Quantum Mechanics (QM). The large quantities of antimatter required would be in the large voids that have been observed in the universe.

I am going to wait for more information, from another source, before I jump on that band wagon. Not being highly trained I have no good way to actually figure out what is going on there. My main top-of-the-head problem with it is that I would think that the antimatter in the voids would clump together and make antimatter stars and galaxies. We don't see them, after all the lack of stars and galaxies in the voids is why we notice them.

Apparently Anti-matter can be seen- indirectly at least.

In 1978, gamma ray detectors flown on balloons detected a type of gamma ray emerging from space that is known to be emitted when electrons collide with positrons — meaning there was antimatter in space.
Gerry Skinner, an astrophysicist at Goddard Space Flight Center in Greenbelt, Md., stated these gamma rays apparently came from a cloud of antimatter roughly 10,000 light-years across surrounding our galaxy's core. This giant cloud shines brightly with gamma rays, with about the energy of 10,000 suns.
Now, an international research team looking over four years of data from the European Space Agency's International Gamma Ray Astrophysics Laboratory (INTEGRAL) satellite has pinpointed the apparent culprits. Their new findings suggest these positrons originate mainly from stars getting devoured by black holes and neutron stars.
As a Black hole or Neutron star destroys a star, tremendous amounts of radiation are released. Just as electrons and positrons emit the tell-tale gamma rays upon annihilation, so too can gamma rays combine to form electrons and positrons, providing the mechanism for the creation of the antimatter.

The mysterious source of this antimatter has now been discovered — stars getting ripped apart by neutron stars and black holes.
