Part 7/12:
To grasp why quantum systems are powerful, one must consider the implications of the double-slit experiment. When photons are shot through dual slits, they create an interference pattern, demonstrating wave-like behavior. Introducing additional slits yields complex interference patterns, suggesting that a subtler influence—often referred to as "shadow particles"—exists in parallel realms. These reflections of particles across different universes provide tangible insights into the thought experiments proposed by Deutsch.
