Aliens as FTL Humans: Scenario from Sci-Fi Novel

Click For Summary
SUMMARY

The discussion centers on the concept of aliens as future humans who have mastered faster-than-light (FTL) travel, allowing them to propagate throughout the universe and travel back in time. This scenario raises questions about causality violations and temporal paradoxes, particularly in relation to the origins of human achievements like the pyramids. The conversation references popular science fiction authors such as Charles Stross and Alastair Reynolds, and explores the implications of time travel on historical events and timelines.

PREREQUISITES
  • Understanding of faster-than-light (FTL) travel concepts
  • Familiarity with temporal paradoxes, including the grandfather paradox
  • Knowledge of popular science fiction literature, specifically works by Charles Stross and Alastair Reynolds
  • Basic grasp of causal loops and their implications in time travel narratives
NEXT STEPS
  • Research the grandfather paradox and its implications in time travel theories
  • Explore the concept of causal loops in science fiction and philosophy
  • Read works by Charles Stross and Alastair Reynolds to understand their take on FTL travel
  • Investigate the butterfly effect and its relevance to time travel and historical events
USEFUL FOR

Science fiction enthusiasts, writers, and theorists interested in the implications of time travel, causality, and the intersection of human history with speculative futures.

What do you think of the following scenario*? Aliens are future humans who discovered faster than light travel. They propagated throughout the universe. In so doing they traveled back in time, to our time, or even earlier times.

*I read this in a popular space opera novel. It may have been Charles Stross or Alastair Reynolds. But I am not certain.

Thanks for the news article. Here's another thought - also thunk by someone else first. If aliens are future humans who flew back in time to teach us about pyramids so we can advance and eventually become them, travel back, and teach our ancestors ... and round and round ... *where* did the idea for pyramids come from in the *first* place?
 
Any and all discussions about timelines that interact with themselves makes me think of this.

Perhaps this explains why a certain high-up member of the conspiracy establishment has a thing about reptilian shape-shifters (who secretly rule the world). Perhaps they're just humanoid speculators from the future, hoping to make a killing on the stock market?

Changes in the money flow would have a butterfly effect and eliminate the supposed beneficiaries of such changes.
