There is a subtle, thrilling moment where the ground shifts beneath our feet.
It might be the page in a novel where a fictional world clicks and suddenly feels more real than the room you’re in. Or the scientific concept that, once grasped, reframes everything you thought you knew. Even the high-stakes “What If?” scenario, no matter how wild, that aligns just enough with reality to capture the imagination.
When disbelief loosens, doubt stirs, and certainty yields toward wonder. That is the Threshold Effect.
This blog is an exploration of that shift.
Meet the Curator: Jay Angeline
Jay Angeline writes science fiction and fantasy for people who care about why imaginary worlds work.
Blending short fiction with research-driven articles on worldbuilding and science, Jay explores the threshold where disbelief gives way to belief: the small, often overlooked details that make a fictional universe feel lived-in, coherent, and alive. The focus is character-first storytelling, set against worlds with deep history, internal logic, and consequences that ripple outward.
With a background in physics and over twenty years of analytical work, Jay brings a systems-level way of thinking to speculative fiction, asking how magic, technology, culture, and psychology intersect, and what breaks when they don’t. The goal isn’t to drain the wonder from storytelling, but to strengthen it by understanding the mechanics beneath the magic.
Raised on space operas and sprawling fantasy epics, Jay has been mentally taking fictional worlds apart (and reimagining them) since childhood.
This site is for writers, readers, and science-minded dreamers who want their worlds to feel believable without becoming joyless, rigorous without becoming rigid, and always with a slight edge of humor. Because in the end, it’s all make-believe, and that’s part of the fun.
