1. When Professor Searle announced the end of get out of class and talked with his grandson Eero, a shy boy hurried through them and secretly placed an apple on the professor's table. This is a reference to the movie "Indiana Jones" In the scene.
2. When Searle explained to Eero what he thought of Eero’s father, Gabriel, he once told Eero that because he is not an "expert in quantum mechanics", he cannot fully understand time travel. And this movie deals with time travel and relativity, not quantum mechanics. Relativity solves macroscopic problems, and quantum mechanics solves microscopic problems. The reconciliation of the two has always been the dream of physics-" Unified Field Theory ". The statement that "time travel is not understood because it is not in the category of quantum mechanics" is absurd. No physics professor would make this mistake.
