What Is the Period of Quark Confinement

question 69

Multiple Choice

What is the period of quark confinement?

• A) Because of the very large pressure in early times, all the quarks were confined to a small volume. After the inflationary epoch, the pressure dropped and the quarks were able to spread out to assume the distribution found today.
• B) During the period of quark confinement, the energy of the photons was sufficiently high that conglomerations of quarks, such as neutrons and protons, could not exist and quarks were free.
• C) During the period of quark confinement, the energy of the photons was sufficiently low that conglomerations of quarks, such as neutrons and protons, could exist without being blasted apart as soon as they were formed.
• D) The period of quark confinement was the very early period in the universe when all matter and energy were confined to a region the size of a single quark.
