The quark-gluon plasma existed at the beginning of the universe. Physicists are searching for signs that even the smallest high-energy nuclear collisions can create the QGP. The Science Physicists are searching for signs that even the smallest high-energy nuclear collisions can create a hot, dense state of matter known as the quark-gluon plasma (QGP). These small collisions are of light nuclei that have relatively low nu... [2984 chars]
