The Solar System.
If the Super Spacetime Cross-Observation Instrument were activated, the workings of the universe would come into clear view from high above the sea of stars.
The star system known as the Solar System did not float alone in the void. It lay within the gravitational well of the supermassive black hole at the Milky Way Galaxy's center, orbiting at roughly 230 kilometers per second with an orbital eccentricity of 0.02.
Every 226 million years, the Solar System completed one orbit around the galactic center, its path tracing a faint silver ellipse through interstellar dust.
Pull the view back ten thousandfold, and the Milky Way Galaxy—a barred spiral galaxy 100,000 light-years across, with hundreds of billions of stars—shrank to a speck on the map of Ganyou Universe Country.
One of the Human Race's 1,008 advanced universe countries, Ganyou Universe Country was, in essence, a gravitational assembly of dozens of giant galaxy clusters. At its heart sat the Ganyou Core Black Hole, more than a million times as massive as the black hole at the Milky Way Galaxy's center.
Its terrifying gravity drew every subordinate galaxy cluster, including the Milky Way Galaxy's, into slow orbits measured in millions of years. Gravity stretched the interstellar medium between the clusters into filaments, weaving a vast gravitational web through the void.
Broaden the view to the entire Primal Universe, and the Human Race's immense territory was no more than a small inhabited patch near its center.
At the heart of the Primal Universe lay the Tuoya Black Hole, a "primordial core black hole" holding one-tenth of the universe's total mass.
It was no ordinary gravitational body, but a remnant of the spacetime Singularity from which the Primal Universe had been born. Its gravitational field pierced
every dimension, drawing every galaxy cluster and
