Geologists are trying to recognize the magnitude of this change by giving our epoch a special name: “the Anthropocene,” the age of humans. Some people find this depressing because they think that the Anthropocene is inevitably a bad thing. But it’s not. Because we aren’t bacteria. Those brains that give us the ability to harness energy also give us the ability to shape the way the planet is transformed. We can design our future.
We think Psyche is the metal core of a small planet that was destroyed in the high-energy, high-speed first one one-hundredth of the solar system’s time.
