The building was constructed for Expo 86 and opened in 1985 as the Expo Preview Centre, becoming the Expo Centre in 1986 when the fair opened. During the world’s fair, the pavilion housed the Futures Theatre, a theatre with push-button voting. The film, A Freedom to Move was featured in the OMNIMAX® Theatre.
The Science World “golf ball” is actually a geodesic dome, the design of which was created by American inventor R. Buckminster Fuller (1895–1983). Fuller patented 28 inventions in his lifetime; perhaps the most famous is the geodesic dome which was patented on June 29, 1954. One of the most famous geodesic domes in the world was the American pavilion at Expo ’67 in Montreal. The original architect for the Science World dome was Bruno Freschi. The architect for the additions made to transform Expo Centre into Science World was Boak Alexander.
In addition to the OMNIMAX Theatre and the Science Theatre, Science World is home to five permanent galleries: Eureka! Gallery; Search: Sara Stern Gallery; the Kidspace Gallery; Our World: BMO Sustainability Gallery; and Puzzles and Illusions. It also boasts a feature gallery for special exhibitions, the Peter Brown Family Centre Stage for live science shows, the Kaleidoscope Science Store, Triple O’s White Spot restaurant and administration offices.
