quark confinement in early universe

[Rothiemurchus]

When the universe expanded so that the quarks in it reached a
separation
of 10^-15 metres, did quark confinement create new quarks,and if so,
what proportion of the quarks that galaxies are made of, were created
by confinement?

[marlon]

well, certainly not in the beginning...Well there was no quarkconfinement...at least if we "believe" (and we sure do) asymptotic freedom...The distance scale and corresponding energies were far too great for confinement to occur...This state of matter is called quark-gluon plasma...


But during the expansion ??? I don't really know but it seems unlikely to me...for some mysterious reason...

someone else got anything to say about this ???
