Here's the part of Cause and Effect I don't get.
The crew chooses not to turn back because 'Maybe turning back is what leads to the accident'.
Yeah, maybe. But then why can't you then just choose a random direction calculated based on background radiation that would be guaranteed to be different each pass? That way if somehow you did generate the exact trajectory that led to the accident, you wouldn't on the next pass.
How would it be different each time? Is the radiation at stardate 45652.10975893 going to be different the second time through compared to the first time through?
