juxtapphere
Juxtapphere is a speculative concept describing the hypothetical phenomenon of multiple distinct realities or universes coexisting in immediate proximity without interaction or awareness of each other. It is not a scientifically recognized term or phenomenon but rather a thought experiment often explored in philosophical discussions about the nature of reality, consciousness, and the possibility of parallel universes. The idea suggests that "here" might not be a singular, exclusive location, but rather a dense superposition of countless "heres" belonging to different realities.
The concept of juxtapphere is rooted in the philosophical exploration of what constitutes existence and presence.
