History

Earth-54 is an alternate universe, first described in Crisis on Infinite Earths: The Compendium. The planet Earth in this universe is technologically advanced in various scientifical fields; Tommy Tomorrow landed on Mars in 1960, as an example. "Mars-54" was covered in canals, supported lush jungles, and held the fossilized remains of long-dead dinosaur-like animals.[1]

In the universe of Earth-54, Earth's moon has an atmosphere (but one that is poisonous to humans) and supports plant life that gives off toxic pollen. Humanoid aliens once lived on the moon and left a time capsule that was discovered by Tomorrow in 1967.[2]

Venus is inhabited by a strange fauna and flora, and rains every 5 hours. Judging by the American flag planted on Venus by Tommy Tomorrow, the United States of Earth-54 had not conferred statehood on Alaska and Hawaii by his time.[3]

Virtually every other planet and moon in our Solar System is inhabited by some kind of lifeform. [4] [5]

The element 99 was only discovered in 1988 and, if sprayed on the atmosphere, it would protect the humanity from a Nova. [6] (In Real World, this element is Einsteinium, which was discovered in 1952.)

Crisis on Infinite Earths: The Compendium stated that the following comics were appearances of Earth-54:

This universe was presumably destroyed during the Crisis on Infinite Earths event, and then (presumably) retroactively saved from destruction during the Convergence event.

Notes

  • Crisis on Infinite Earths: The Compendium lists entire issues rather than specific stories as being Earth-54 stories so it cannot be determined if stories that don't contradict larger continuity told in those issues happened on Earth-54 or the Earth being depicted at that time.
