Several centuries ago (in the 16th century), Nicolaus Copernicus literally changed the prevailing views of astronomy by formulating a comprehensive heliocentric cosmology, which displaced the Earth from the center of the universe. Copernicus's heliocentric model demonstrated that the observed motions of celestial objects can be explained without putting Earth at rest in the center of the universe. His work stimulated further scientific investigations and ushered the Copernican Revolution. Regardless of whether you are an astronomer or scientist, celebrate the heliocentric model of the solar system with wry humor with this Obama-Like Poster, with the caption "Heliocentric" on any of these gifts. No need to be involved in political change to remind everyone about who really changed the dominant view of the world!
