About 4.5 billion years ago, a distant visitor comes to Earth.
Just outside the edge of Earth's solar system, a large spherical vessel cuts through the fabric of space like a knitting needle slipping through a bubble. After a quick lightspeed jump, it becomes stationary, floating near Neptune. It then rotates slowly, adjusting its trajectory to align with the Sun.
Once the object's course is set, the metallic ball goes from stagnant to a blurred stream shooting past Saturn, gliding across the planet's rings. The warped space trail leaves the Ringed Planet and loops around Jupiter using its gravitational pull to sling itself toward Earth.
On its way to Earth, the craft maneuvers between Phaeton and Mars, sending a gravitational wave through Phaeton's surrounding space-median - the waves are left rippling in its trails.
