Jumpgates

The Jumpgates were created by the Progenitors in order to promote faster-than-light space travel. Each Jumpgate connects to several other Jumpgates, but no Jumpgate connects to all other Jumpgates. Sometimes, more than one pair of Jumpgates is necessary to reach a given destination. Usually, a solar system has only one Jumpgate. A Jumpgate is a purple-colored hoop about 500 Earth miles in diameter, the size of a small-to-medium moon or a large asteroid or a dwarf planet. The matter that makes up a Jumpgate is in a slightly different plane of existance, meaning it can be seen and used in the normal universe, but unlike regular solid matter it is physically untouchable and virtually indestructible. A route linking two Jumpgates is activated by a certain combination of radio signals and magnetic pulses, which opens up a white-colored wormhole between the two Jumpgates. This wormhole provides instant travel between the two solar system and lasts up tp two or three Earth hours.
