Tom's energy remained almost entirely focused on technological development.
Numerous large scientific devices, countless large, medium, and small laboratories, over a billion clones, and millions of Bluetoth scientists toiled relentlessly, not daring to rest for a single day.
Time slowly passed under these circumstances, and in the blink of an eye, over six hundred more years had elapsed.
The vast distance of 50 light-years was quietly traversed by Tom through day-after-day navigation.
At this stage, the fleet's distance from the solar system had reached over 80 light-years. The Sun, viewed from here, had its apparent magnitude reduced to approximately 7.
The dimmest star that the human eye can see under ideal conditions has an apparent magnitude of about 6.5.
This means that the Sun was now invisible to the naked eye.
Tom looked out at the starry cosmos and also saw a sky full of stars. But among those stars, the Sun was no longer visible.
