Query: Quark-gluon cluster -- a composite entity just due to color confinement   We incorporate confining effects into statistical formulation of quantum
chromodynamics (QCD). It implies that quark-gluon clusters existed in the early
universe, triggering the information accumulation in nature. The
confinement-driven clustering would explain the reason why the quark-gluon
plasma in the heavy-ion ollision experiments looks like liquid unlike the QCD
expectation.
