From looking at the Wikipedia entry on string theory I gather that it is found that any given physical model implies two Calabi-Yau spaces.(adsbygoogle = window.adsbygoogle || []).push({});

Perhaps one space gives rise to a sector of particles with left-handed weak interactions and the other gives rise to a sector with right-handed weak interactions.

The right-handed sector might be the dark matter.
