I’m not entirely sure for whom this novel is written or what the overall plot is – but it does make me think about the flexibility of the time line.
We’re deeply entangled in space and time – but if people can’t deal with different cultures or with people who change location how can we expect to deal with time travelers?
A watched kettle never boils. Does this make it a quantum or even just a steam powered time machine?
Do we have a free will when we make a decision with time travel? Is the past fixed, and the future a set fate or destiny? The linear model of time doesn’t account that knowledge of the future affects the past, when even logic would suggest that is so. Alternative (multidimensional) models, such as those given by quantum mechanics would perform better. The future is yours. So is your history!
