Photons and determinism, part 2

[Surgenator]

The framework of a photon is an invalid framework. Naively interpreting the physics equation will give a no passing of time. However, the equations don't work in the photon framework, thats why they're invalid.

Why invalid? Is this special pleading, or is there a reason why it is considered an invalid framework?

In the relativity equations you will be dividing by zero if you go into the photon's rest frame. Thats what makes it invalid.

Still, 1000 years in our framework is a lot of time for something to happen to our solitary little hero photon, but 0 seconds in ITS framework is obviously no time for anything to happen to it. I'd like you to explain why you don't feel this framework should be considered in philosophical arguments about determinism. Why is it "invalid"?

The number of interactions that happen to the photon is independent of the reference frame. The time between two or more interactions would be spaced differently for different reference frames. Moving reference frame would see a smaller time difference between interactions compared to the stationary one. In the photon reference frame, all the interactions occurred at once which would break causality if the photon didn't get destroyed with each interaction.

AHHHHHH, how could I possibly forget about gravity. :pulls-hair-out:

A passing by gravitation object can deflect the photon from your eye.

But I think it doesn't, because a photon cannot really be "changed," being timeless, can it?

Imagine a photon starting on the trajectory toward your eye. Midway between galaxies, a flying black hole and photon have a close encounter. The black hole would change the trajectory of the photon.
