Resonance – The idea of resonance—where small impulses, precisely matched to a system’s natural rhythm, can get amplified into powerful forces—is rooted in real scientific phenomena seen in mechanical and electromagnetic systems. However, the concept of using mental resonance with the compass to trigger time travel is entirely fictional.

Hidden powers of the brain – The notion that the conscious mind represents only a small fraction of the brain’s full potential is based on real neuroscience concepts [Eagleman-1]. In addition, the idea that the brain’s visual cortex can activate—especially when external sensory input is reduced, as in dreams—is explored in [Eagleman-2]. In the novel, these ideas are woven together to imagine how focused mental states might enable extraordinary phenomena like time-travel resonance.
