comment Are quantum mechanics and determinism actually irreconcilable?
My advice would be "don't tell the nature how it should behave." The universe doesn't have to conform to our naive philosophical biases. I tend to show people the following video when questions like these come up: youtube.com/watch?v=iMDTcMD6pOw .

comment Is energy always proportional to frequency?
The difference is the immense scale difference. Each particle in the cat has an attributed de Broglie wavelength, but since Planck's constant is so tiny these waves are very very small compared to the total size of the cat.

comment Is energy always proportional to frequency?
I'm not really sure what the question is. First of all, frequency of what? As for energy that isn't proportional to frequency, how about potential energy?

comment Gravitational Redshift around a Schwarzschild Black Hole
You're using Schwarzschild coordinates. In this coordinates $r$ does not correspond to radial distances. Physical distance which you would measure with a ruler correspond to an integral over $ds$. 99% of all confusion in GR comes from taking coordinates too seriously.

comment Gravitational Redshift around a Schwarzschild Black Hole
Just to nit-pick, $r$ isn't "the distance of the torch from the centre of the BH," it's just a coordinate. It doesn't correspond to radial distances.
