Boom tube



A Boom Tube is a transient interdimensional corridor used as a transportation system by an extraterrestrial "partner" of The Light. The Light consider the Boom Tube to be a "delivery system" for new technology, and as a test the Boom Tube was used to deliver the Sphere to the Bialyan desert for study.

Background in other media
In the comics, Boom Tubes are used by the inhabitants of the worlds New Genesis and Apokolips as created in Jack Kirby's 4th-World series of comic books and used extensively in other DC properties.

A Boom Tube is summoned into being by Apokolips/New Genesis technology, usually in the form of a "Mother Box" or hand-held "living computer" capable of determining the destination. The tube appears with a blast of energy and resounding "BOOM" and connects unlimited distances in Space/Time through a short corridor. The Tube disappears quickly and without a trace if it is not actively kept open.
