The high energy at the time and the creation and destruction of a large number of quarks and antiquarks would also create a variety of flux tubes, some of which could be knots.
Knots Could Explain Why The Universe Is Three-Dimensional
Furthermore, pairs of quarks and antiquarks randomly materialize out of the seeming emptiness of space forming a sea of short-lived particles that interact with the other quarks and gluons already present in baryons and mesons.

For instance, it's possible that the fivefold structure is not a spherical lump but rather a moleculelike arrangement in which a so-called kaon, which is made of a quark and an antiquark, orbits a neutron, which is made of three quarks.

This structure, called a chiral condensate, consists of quark-antiquark pairs, but only certain types of quarks pair up with certain types of antiquarks.
