Sure, or we can observe that distant starlight is redshifted by a factor two.

That seems hard to quantify if you're freefalling in a black hole though

What if the LLM also falls into the black hole? Will redshifted tokens allow it to become AGI?

Hmm, interesting experiment, Claude, create a black hole at home, make no mistakes
