Roughly 300 years ago, after studying ancient records of eclipses, British astronomer Edmond Halley conceived of a theory that the moon was in fact physically moving away from the Earth. The moon’s recession was later confirmed in the 1970s by laser beams bouncing off mirrors placed on the moon by American and Soviet astronauts. Caused by drags in ocean tides, which slow the Earth’s spin rate, the accelerated rate compensates for the loss of angular momentum, and the moon gradually pulls away at a rate of 3.78 cm a year – about the rate at which our fingernails grow.  Upon learning this, Hong Kong artist Phoebe Hui’s existing fascination with the celestial body gained newfound urgency. “For some reason, this matters to me, despite the fact it doesn’t affect us during our lifetime,” she says.
