Guardians of the Galaxy: Cosmic Rewind at EPCOT replaced the Universe of Energy pavilion, specifically the attraction known as Ellen’s Energy Adventure. The original Universe of Energy opened with the park in 1982 and featured a "traveling theater" system where guests rode in massive battery-powered vehicles through dioramas of audio-animatronic dinosaurs. In 1996, it was updated to Ellen’s Energy Adventure, starring Ellen DeGeneres and Bill Nye the Science Guy in a comedic exploration of energy sources. This version ran for over 20 years before closing permanently on August 13, 2017. Disney kept the massive "show building" from the original pavilion—which is large enough to hold four Goodyear Blimps—and repurposed it to house the loading area and early scenes of the new Guardians coaster. The actual high-speed coaster portion of the ride takes place in a newly constructed, even larger building located just behind the original structure.
