The Block Universe

The Block Universe is a concept in physics and philosophy suggesting that past, present, and future are equally real and part of a four-dimensional 'block' of spacetime. Instead of time flowing or changing, all moments exist simultaneously within this block. This means that events are fixed in space and time, and our experience of moving through time is akin to traveling through a static, unchanging structure. In this view, the universe is like a giant, unalterable landscape where everything that has happened and will happen is already laid out.
