Death's End

But ten days later, Bronze Age received a radio transmission from Fleet Command. The transmission had been sent simultaneously to Bronze Age and Blue Space, which was at the other end of the Solar System. The transmission gave a brief account of what had happened on Earth and notified them of the successful creation of a deterrence system to defend against Trisolaris. The two ships were ordered to return to Earth immediately. Moreover, Earth had taken great risks to send out this message to the lost ships; it would not be repeated.

At first, Bronze Age dared not trust this message—wasn’t it possible that it was a trap set by those who had conquered the Solar System? The warship stopped accelerating and repeatedly queried Earth for confirmation. No reply ever came, as Earth maintained radio silence.

Just as Bronze Age was about to begin accelerating away from home again, the unimaginable happened: A sophon unfolded into low dimensions on the ship, establishing a quantum communication channel with Earth. Finally, the crew received confirmation of all that had occurred.

The crew found that, as some of the only survivors of the holocaust suffered by the combined space forces of Earth, they were now heroes of the human race. The whole world awaited their return with bated breath. Fleet Command awarded all members of the crew with the highest military honors.

Bronze Age began its return voyage. It was currently in outer space, about twenty-three hundred AU from the Earth, far beyond the Kuiper Belt but still some distance from the Oort Cloud. As it was cruising near maximum speed, deceleration consumed most of its fusion fuel. Its journey toward the Earth had to be conducted at a low cruising speed, and took eleven years.

As they finally neared Earth, a small white dot appeared ahead of them and quickly grew. It was Gravity, the warship that had been dispatched to welcome Bronze Age.

Gravity was the first stellar-class warship built after the Doomsday Battle. Deterrence-Era spaceships were no longer constructed along fixed body plans. Rather, most large spaceships were constructed out of multiple modules that could be assembled into various configurations. But Gravity was an exception. It was a white cylinder, so regular that it seemed unreal, like a basic shape dropped into space by mathematical modeling software, a platonic ideal rather than reality.

If the crew of Bronze Age had seen the gravitational wave antennas on the Earth, they would have recognized Gravity as an almost perfect replica of them. Indeed, the entire hull of Gravity was a large gravitational wave antenna. Like its twins on the Earth’s surface, the ship was capable of broadcasting gravitational wave messages toward all corners of the universe at a moment’s notice. These gravitational wave antennas on Earth and in space comprised humanity’s dark forest deterrence system against Trisolaris.

After another day of coasting, Bronze Age, escorted by Gravity, entered geosynchronous orbit and slowly sailed into the orbital spaceport. Bronze Age’s crew could see dense crowds filling the broad expanse of the habitat sector of the spaceport like the opening ceremony of the Olympics or the Hajj in Mecca. The warship drifted through a colorful snowstorm of bouquets. The crew looked through the crowd for their loved ones. Everyone seemed to have tears in their eyes, crying out in joy.

With a final tremor, Bronze Age came to a complete stop. The captain gave a status report to Fleet Command and declared his intent to leave a skeleton crew behind on the ship. Fleet Command replied that the priority was to quickly reunite all members of the crew with their loved ones. There was no need to leave anyone behind on the ship. Another captain from the fleet boarded the ship with a small duty team who greeted everyone they encountered with tearful embraces.

It was unclear from the duty team’s uniforms which of the three space fleets they belonged to, but they explained to those aboard the ship that the new Solar System Fleet was a single, unified force, and all those who had been part of the Doomsday Battle—including all the men and women aboard Bronze Age—would be key figures in the new fleet.

“In our lifetimes, we will conquer Trisolaris and open up a second solar system for human colonization!” the fleet captain said.

Someone replied that they found space too terrifying and they would rather remain on the Earth. The fleet captain said that was perfectly acceptable. As heroes of humanity, they were free to choose their own paths in life. However, after a bit of R&R, they might change their minds. He, for one, hoped to see this famed warship in action again.
