The Galaxy Warp is the former central hub on Earth for interstellar transport through the galaxy used by Gems, replacing the Colony type ships. The system consists of numerous Warp Pads of varying sizes that have been inactive for thousands of years. The Galaxy Warp is located atop a large plateau, surrounded by the Tunguska Sea and numerous smaller islands.
Six massive crystalline rock formations surround the perimeter of the summit, which houses sixteen individual Warp Pads arranged in a crop circle-like pattern. The central pad directly links Earth with the Gem Homeworld.
The Crystal Gems follow Peridot's robonoids back to the Galaxy Warp where they proceed to repair the Homeworld warp, allowing Peridot to warp there. She then hastily retreats upon discovering one of the stickers, believing the site has been "compromised". Garnet proceeds to smash the Homeworld warp pad, effectively cutting off travel to and from Homeworld via warping once again.
While not featured in the actual episode, Steven discovers through his future vision that the Gems launched the Shooting Star directly to the Galaxy Warp with the objective of destroying it once and for all.
The Galaxy Warp appears to be untouched by the Shooting Star. Peridot was seen attempting to repair the Homeworld Warp before fighting the Crystal Gems and later using the only active warp pad to escape.
After breaking into the Beach House and abducting Steven, Peridot brings him to the Galaxy Warp so that he can attempt to use his healing powers to fix it. When he is unsuccessful, Peridot begins to panic about being trapped on Earth and begins to tell Steven about "something dangerous" and what is about to transpire on the planet. However, before she can give him any details, the Crystal Gems show up and successfully poof and bubble Peridot. Amethyst then proceeds to toss the remaining limb enhancers into the surrounding ocean.
Schematics for the Galaxy Warp are seen on the Moon Base computer display.
When Lapis Lazuli is telling her backstory for why she was stuck on Earth, she states that "It soon became clear there was no hope in stopping the rebellion", and we see the Homeworld Warp being used which is at the Galaxy warp.
- In "Winter Forecast", Pearl mentions that Homeworld Gems can reach Earth without using the Galaxy Warp, such as by traveling in a Gem Warship.
- Rebecca Sugar first hinted that the Crystal Gems were intergalactic at the first standalone Steven Universe panel at San Diego Comic-Con.
- It has a crop circle symbol pattern that occasionally appears in the series.
- In an alternate timeline, seen using Garnet's future vision, Steven interrupts the warping process and the Shooting Star detonates, destroying the Crystal Temple.
- Almost all of the Warp Pads at the Galaxy Warp are heavily damaged (and thus rendered inactive), the most severely damaged being the Homeworld Warp as of "Friend Ship".
- The domestic Warp Pad is the only currently functioning Warp Pad at the site.
- As of "Catch and Release", Peridot has reassembled most of the pieces of the Homeworld Warp, (likely with her tractor beam primarily), although without Flask Robonoids she cannot fully repair it. She tried using Steven and his healing abilities to finish reconstructing it, but failed.
- During Lapis' flashback in "Same Old World", the water level around the galaxy warp was a lot higher than it is at the time Steven and the Crystal Gems visit the site.
- In Steven Universe: Art & Origins, there is a map by Joe Johnston showing the Galaxy Warp to be in the center of the Tunguska Sea, a fictional sea in Siberia. However, this location is contradicted by "Warp Tour", in which it is night in Beach City and at the Galaxy Warp simultaneously, and by "Same Old World", in which Steven and Lapis make a short and seemingly subsonic flight from Jersey to the Galaxy Warp. Joe Johnston's map was a concept map, so it is likely that the location of the Galaxy Warp was changed for plot convenience (though the Tunguska Sea can be seen on a holographic map of Earth in "It Could've Been Great" with a Gem facility at the center, and is thus still a canon location in the version of Earth seen in the show.)
