The Solar System.
The nine planets revolved endlessly around the heart of the system, like stars gathered around the moon, like loyal sentries unchanged since time immemorial.
The Solar System's sole source of light radiated endless light and heat, driving back the eternal darkness of the boundless universe and illuminating the entire system. It burned itself to kindle the Solar System, and with it, the flame of civilization on Earth.
The Sun was the system's central celestial body, accounting for 99.86% of its total mass. The remaining 0.14%, consisting of various celestial bodies, interstellar dust, and so on, all orbited the Sun, while the Sun orbited the center of the Milky Way.
It was a star of hot plasma interwoven with magnetic fields, approximately 1.39 million kilometers in diameter-109 times Earth's diameter-and roughly 1.3 million times Earth's volume.
In terms of chemical composition, about three-quarters of the Sun's mass was hydrogen, with almost all the rest being helium. It released light and heat into space through nuclear fusion, making it the undisputed energy heart of the Solar System!
Every activity on Earth depended on energy supplied by the Sun. In recent years, as Earth's technology advanced and demand for electricity soared, the photovoltaic industry had grown rapidly, and countries around the world had made increasingly effective use of solar energy.
Now, as Nie Yun's disruptive, fantastical technology increasingly permeated everyday life on Earth, vast cosmic distances and high temperatures could no longer rein in the Earthlings' soaring imaginations. And so, they turned their eyes toward the Sun!
In fact, Freeman Dyson had proposed a theory as early as 1960: the so-called "Dyson sphere."
He believed that the energy contained within a planet like Earth was extremely limited, nowhere near enough to support its civilization's development to an advanced stage. In
