Albert Einstein's mathematical framework of relativity proved that space and time are mechanically fused into a singular, rigid geometric structure known as the "block universe."
In this exact architectural model, time does not actively "happen" or physically move forward. Instead, every single microscopic event—from the absolute beginning of the universe to its final absolute end—already exists simultaneously within this massive four-dimensional coordinate system.
This means your biological consciousness is simply traveling through a pre-existing structural framework. The past has never truly vanished, and the future is already completely constructed; your central nervous system is merely sequentially rendering the environmental data as you physically move along your specific geometric coordinate path.
