Time is ticking. That's what it does. Or at least that's how we represent what we don't understand. For physics, time is a byproduct of so called space-time, elastic goo created at the very moment that something came from nothing; the moment eternity stopped and the universe began. For geology, time is 4.5 billion years of compression and catastrophe. For biology time is 3.5 billion years of diversification and now the urgency of the sixth extinction. For anthropology time is 150 thousand years since mitochondrial Eve walked out of the rift valley in Ethiopia. For historians, time begins with Herodotus (484 BC) and ends, or rather doesn't, with Fukuyama's The End of History. For architecture time is ruination. For landscape architecture time is ephemerality, entropy, and growth. For all of us time is running out.
