Dark Ages

The Dark Ages were a period in Earth history where the Tau'ri had made almost no technological advancements following the collapse of the Roman Empire. For a period of over 800 years attempts of scientific advancements were viewed as heresy and anathema. After SG-1 rescued a group of Tollans from their homeworld following severe volcanic eruptions on the planet, Doctor Daniel Jackson notes that if it were not for the set back, the Tau'ri would probably have colonised space before 1998, and had technology that rivaled the Tollans.
