Start by reading
Heinlein’s “
By His
Bootstraps” (1941), and then read this one. You’ll enjoy both and stretch your mind

Note that the half blueprint itself does have an origin, and you can trace it’s timeline
from that origin to the past and back again. It’s only the concept expressed in the
blueprint that has no origin.
