Alternate universes

Parallel Universes are universes of similar nature and conception as ours, with notable differences. Our / Futurama's universe does not have an official name, though it was coined as "Universe A" by the Planet Express crew, and as "Universe Gamma" by Yivo. Parallel universes can be accessed by a Parallel Universe Box and through an Anomaly.
