From deer videos to a 4D time machine: the 'spatial memory palace' for physical reality

Creator bilawal sidhu showcases a series of 4D reconstruction experiments: turning an ordinary video of a mama deer and her babies into a freely navigable 4D scene, rebuilding the TED stage and Prime Air Flight 7598 from photos, and revisiting the same spot in both summer and winter.
His framing concept is the "spatial memory palace": photos and videos become walk-in, re-visitable memory spaces — an audit trail for physical reality. The longer-term vision is a time machine for the entire planet, evolving into a global 4D commons.
The video walks through how 4D reconstruction works, replaying your whole life at once, philosophical tangents on free will and "cosmic scribes," and where a God's-eye view goes next.
