We are all ancient astronauts traveling through the cosmos. None of us are from this place we’re in—we are made of star stuff created in the crucible of the Big Bang. Our home, this Earth, is flying too, away from the fog of the Milky Way and hurtling toward the constellation Hercules at 45,000 mph. In just 100,000 light years we’ll zoom round-trip right back to where the journey began 4.5 billion years ago. Hold tight and ride the light.
