TENET/テネット 「銃弾の跡はいつからあったのか？」問題の考察【一部ネタバレ】

*This video is in Japanese, but with machine translated English subtitles added. In this video, we consider the mystery of "TENET", the "when did the bullet marks exist? There will be several scenes of "reverse bullet holes" due to retrograde bullets, such as "opera house bullet holes", "glass windows in the revolving door room of the art warehouse", and "BMW door mirrors in the car chase scene". Was it? That's the problem. This time, I considered these problems in relation to the "observation problem" of quantum mechanics. In addition, "Double Slit Experiment", "Copenhagen Interpretation", "Everett's Many-Worlds Interpretation" and "Schrödinger's Cat" are introduced.
