$2.99 Space was still expanding rapidly after the creation. The
Universe was about the size of our Solar System today. The
quark-gluon plasma was getting larger and its quarks were being
pulled further apart. Now the strong force carried by gluons
revealed an exotic and important property. As quarks moved
further apart, the gluon elastic force began to increase, and
increase very rapidly. When the distance between any two quarks
was more than 10-15 meters, the gluon elastic broke and produced
two new quarks, one at each end of the break. Not only was the
space between quarks increasing as space expanded; they were
also moving more slowly. The temperature dropped to around 10
thousand million degrees Celsius. Soon they did not have enough
energy to break the gluon elastic, and each quark found itself
permanently tied to one or more of its neighbours. The Hadron
Epoch started about 10-6 seconds after the creation and ended
about 1 second later. Qu
