Accompanist of 4.5 Billion Years

In this solar system, there is a session that has continued for 4.5 billion years: Earth and the moon. Drawn to each other by gravity, they dance together around the sun. It looks like they are running side by side, yet at the same time they play out a rhythm across the cosmos. Lunar material is said to retain much information about the primordial Earth and moon. This piece, made using lunar sand, has a rock-like quality that evokes the very beginning of that 4.5-billion-year history. *Lunar regolith simulant grains and colored glass made from them are used for the primordial Earth and primordial moon.
