  The history of dark universe physics can be traced from processes in the very
early universe to the modern dominance of dark matter and energy. Here, we
review the possible nontrivial role of strong interactions in cosmological
effects of new physics. In the case of ordinary QCD interaction, the existence
of new stable colored particles such as new stable quarks leads to new exotic
forms of matter, some of which can be candidates for dark matter. New QCD-like
strong interactions lead to new stable composite candidates bound by QCD-like
confinement. We put special emphasis on the effects of interaction between new
stable hadrons and ordinary matter, formation of anomalous forms of cosmic rays
and exotic forms of matter, like stable fractionally charged particles. The
possible correlation of these effects with high energy neutrino and cosmic ray
signatures opens the way to study new physics of strong interactions by its
indirect multi-messenger astrophysical probes.
