You can singlehandedly create a causal relation between two things that are currently unconnected — a word and an emotion, a song and an extreme weather event, wearing a certain color and winning the lottery. What cause would you link to what effect, and why?
In chaos theory, the butterfly effect is the sensitive dependence on initial conditions where a small change in one state of a deterministic nonlinear system can result in large changes to a later state. The butterfly effect is a common trope in fiction, especially in time travel.
I am a butterfly. I flap my dainty wings, then a tornado tears through Oklahoma. Would not flying at that precise minute, at that moment in time, have prevented the tornado?
I am a robin. I flap my dainty wings, after which a hurricane blows across an island in the Caribbean. If I had stayed on that fence, would the hurricane have passed by, unformed? If I had flown sooner, would the wind have blown in a different direction?
Cause, meet effect. In reality, in fantasy, in the tunnels of time.
Do we really know what the effect is or will be when we do (or fail to do) anything … any more than the butterfly or the robin can predict the ultimate result of his or her wings?
I can imagine many answers. But I have more questions … many more than I have answers.
