If you are passing light from light years away through it does the behavior of the electron still change based on observation?
In: Physics
A photon is a photon, whether it was created nanoseconds or years ago. Also, to the photon, time does not pass!
If you want to, the [Quantum Eraser Experiment](https://en.m.wikipedia.org/wiki/Quantum_eraser_experiment) (or better yet, [Delayed-Choice Quantum Eraser](https://en.m.wikipedia.org/wiki/Delayed-choice_quantum_eraser)) may be of interest to you, looking at what happens if you work with quantum-entangled particles in a double-slit experiment.
dude that’s a wild thought. like light from light years away still acting like it’s “watched” is crazy. it’s like the universe is always on show.
dude that’s a wild question like light years away and still affects things here. it’s like we’re all connected in this weird quantum dance. still changes based on observation tho. crazy stuff right
