A free sf (science fiction) invariant short story could be a science fiction story that has some element which remains constant or 'invariant' throughout the narrative, and it's available for free.

Also, some independent author websites might offer their sf invariant short stories for free as a way to gain readership.
Arthur C. Clarke's short stories are also great. 'The Sentinel' is a classic. It's about a strange object on the moon that makes you wonder about alien life and the future of humanity. His writing combines scientific concepts with great storytelling, and these free short stories are definitely worth reading.
Yes, many are. Some emerging authors use the free online platform to showcase their talent. They pour their creativity into these short stories. Also, classic sf short stories that are made freely available online are of high quality as they have withstood the test of time.

The 'Divided Man' short SF story may use the concept of division to comment on society. For instance, the divided man could represent the fragmented nature of modern humans. We are often divided between our work self, our family self, and our individual self. The story could be a metaphor for how we struggle to keep these different parts of ourselves in harmony, and what happens when we fail to do so.
