Block universe theory

Block Universe Theory, also known as Eternalism, posits that past, present, and future events all exist simultaneously in a "block" of spacetime. Instead of viewing time as a flowing river with a distinct present, this theory suggests that every moment is fixed and unchanging, much like frames in a film. Our experience of moving through time is just our consciousness navigating this static structure. In essence, every event—past and future—coexists, challenging our intuitive understanding of time as a linear progression.
