Answer
Up until the 17th century, the universe was thought to have more than three bodies, not just Earth, Moon, and Sun.
Solution
False
Up until the 17th century, the prevailing astronomical models, such as the Ptolemaic (geocentric) system, recognized not just the Earth, Moon, and Sun, but also the five known planets (Mercury, Venus, Mars, Jupiter, and Saturn) and countless stars. The introduction of the heliocentric model by Copernicus in the 16th century began to challenge this view, and subsequent observations by astronomers like Galileo and Kepler further expanded our understanding of the universe beyond just three primary bodies.

False! Up until the 17th century, people believed in a geocentric model of the universe primarily proposed by Ptolemy, which did include the Earth, Moon, and Sun as major celestial bodies, but also believed in several other planets like Mars, Venus, and Jupiter, as well as the stars. It wasn’t until thinkers like Copernicus suggested a heliocentric model that the understanding of the universe expanded dramatically!
Fast forward to today, and we reckon the universe is teeming with celestial bodies - planets, stars, black holes, and galaxies galore! With advanced telescopes and space probes, we’ve discovered hundreds of billions of stars even in our own Milky Way, each potentially hosting multiple planets. The universe is like a cosmic treasure chest waiting to be explored!
