Interests And Ideas

Why did I decide to become an sf fan blogger and where do I get my ideas from? We do not decide to be interested in anything but find that we are interested in some things as against others. At primary school, I was interested in cowboys and spacemen, not footballers, just like I happened to be male, not female. 

Ideas for new blog posts pop into my head while I am walking around town. Returning home, I have something to post. I appreciate sf ideas but do not originate them. If I did originate any ideas, then I would have a very limited ability to embody them in fictional narratives. It is the writing, not the conceptualization, that is almost all of the work. I did think of the idea of time travelling within a generation ship before I read the idea in Poul Anderson's There Will Be Time. I do not understand how an author like Heinlein or Anderson plots a circular causality narrative. At what point in the causal circle does he begin to imagine and think about it?

A hypothetical sequel to There Will Be Time might feature not time travellers within generation ships but faster than light spaceships because FTL is meant to be mathematically equivalent to pastward time travel although I don't see how.

There Will Be Time is a classic of time travel and the attached cover image does it justice. Time Patrollers inhabit a completely different timeline.
