"All You Zombies" (short story)

"All You Zombies" by Robert A. Heinlein is a paradoxical time-travel story about a person who is both their own parent and child. The narrator, a time-traveling agent, was born through a series of events involving a self-produced pregnancy and later becomes their own clandestine parent to prevent a future disaster. The story explores themes of identity, fate, and causality, illustrating how actions across different points in time can create a closed loop where cause and effect become intertwined. It challenges conventional notions of linear time and individual identity, highlighting the complexities of temporal paradoxes.
