A Ship of the Law travels the infinite enormity of space, carrying 82 young people: fighters, strategists, scientists; the Children. They work with sophisticated non-human technologies that need new thinking to comprehend them. They are cut off forever from the people they left behind. Denied information, they live within a complex system that is both obedient and beyond their control. They are frightened. And they are making war against entities whose technologies are so advanced, so vast, as to dwarf them. Against something whose psychology is ultimately, unknowably alien.
Yes, Greg Bear explores the concept in Forge of God (1987) and Anvil of Stars (1992), twenty years before Liu. David Brin also covered it.
Anvil of Stars really explores the moral quandary from the perspectives of a civilisation that can take revenge in such an environment.
Greg Bear was the first person who really made me understand time slowing down as speed increases in Anvil of Stars.
Also the destruction of earth in “The Forge of God” was so visceral that I was depressed in a dark place for days after finishing it.
Not to mention one of the few authors who very well explained the role of bacteria and viruses in very entertaining and hard sci-fi believable fashion.
RIP.
