Drop a hammer and a feather on Earth, and the hammer hits first. Drop them on the Moon-as Neil Armstrong did in 1969-and they land simultaneously. This simple demonstration revealed something profound: what we experience as "weight" isn't gravity at all. It's the ground pushing back against us, electromagnetic forces between atoms resisting compression. Gravity itself? We've never felt it. This counterintuitive truth sits at the heart of our cosmic story, one that begins with medieval monks arranging stones and ends with detectors capturing ripples in spacetime itself. The journey from Earth-centered cosmology to our modern understanding required overturning everything humanity believed about the universe-and it started with a beautiful mosaic on a church floor. The Cosmati Pavement in Westminster Abbey isn't just decorative stonework. This 13th-century mosaic encodes an entire worldview, declaring itself "the perfectly rounded sphere which reveals the eternal pattern of the universe." One inscription calculates the cosmos's lifespan as 19,683 years-derived from 3^9, the number three representing the Holy Trinity. This wasn't whimsy. Medieval thinkers built upon Aristotle's model: Earth motionless at the center, surrounded by crystal spheres carrying celestial bodies, all turned by angelic hierarchies, with nine corresponding levels of Hell below. Dante's Divine Comedy gave this vision its ultimate expression, structuring every realm around threes and nines. But while European philosophers debated cosmic architecture, Babylonian astronomers were doing something more practical: recording planetary positions with meticulous precision. They discovered the eight-year Venus cycle and eighteen-year eclipse patterns through patient observation. When Greek thinkers like Thales began predicting eclipses using this data, humanity took its first steps toward modern science.
