Boom Tube - Later Additions To The Concept

Later Additions To The Concept

• Later canon is unclear on whether it is even possible to travel from the regular universe to that of the New Gods without a boom tube or similar device. For example, an issue of Justice League International shows the JLI reaching Apokolips using a normal spacecraft, but Cosmic Odyssey explicitly states that one cannot reach Apokolips or New Genesis without a tube.
• The "tube only" idea was reinforced when later writers introduced the idea that the New Gods were, in fact, giants, and that the boom tube would appropriately shrink or enlarge people who traveled through it. For example, if Superman were to travel to Apokolips in some manner under his own power, he would be miniature (if not microscopic) in comparison to Darkseid. This has apparently become canon in the 52 miniseries, demonstrated by the great size of the New God Devilance the Pursuer. The precise size ratio has varied, with New Gods in their "original" size being depicted as anywhere from tens of feet tall, to tens of thousands of miles tall (as in New Gods #10, 1996).
• In Grant Morrison's Mister Miracle run, it was revealed that the technology is actually referred to as 'boom lanes' by the New Gods. However, the noise disorients the eponymous hero, so he later refers to it as a "'boom tube', or something."
