Em [[Cosmologia]] a '''era quark''' foi o período na evolução do universo em seus estágio inicial, quando as interações das [[Força fundamental|forças fundamentais]]: [[Gravidade|gravitacional]], [[Electromagnetismo|eletromagnética]], [[Força forte|força nuclear forte]] e a [[Força nuclear fraca]]. Tomaram suas formas atuais, mas a temperatura do universo ainda era muito alta para permitir os [[Quark]]s se unirem para formar os [[Hádron]]s. A era quark começou aproximadamente 10<sup>-12</sup> segundo após o [[Big Bang]], quando a era anterior,

In [[physical cosmology]] the '''quark epoch''' was the period in the evolution of the early universe when the [[fundamental interaction]]s of [[gravitation]], [[electromagnetism]], the [[strong interaction]] and the [[weak interaction]] had taken their present forms, but the temperature of the universe was still too high to allow [[quark]]s to bind together to form [[hadron]]s. The quark epoch began approximately 10<sup>-12</sup> seconds after the [[Big Bang]], when the preceding [[electroweak epoch]] ended as the [[electroweak interaction]] separated into the weak interaction and electromagnetism. During the quark epoch the universe was filled with a dense, hot [[quark-gluon plasma]], containing quarks, leptons and their antiparticles. Collisions between particles were too energetic to allow quarks to combine into [[meson]]s or [[baryon]]s. The quark epoch ended when the universe was about 10<sup>-6</sup> seconds old, when the average energy of particle interactions had fallen below the [[binding energy]] of hadrons. The following period, when quarks became confined within hadrons, is known as the [[hadron epoch]].
