2. I posed the following question to ChatGPT in the same session: "Does redshift due to a gravity well remain after it leaves the well?"
Here was its response:
Do you agree with this response from ChatGPT, and/or do you think there are any lack of understanding or mind reader issues? (I don't mind being told that I don't understand, or that I'm wrong about anything - I don't take offense to it and I welcome it. )
The Earth is in such a tiny gravity well that it makes virtually no difference.
As for "it doesn't completely disappear" answer, that is just chatGPT being dumb. The gravity from a grain of sand on the other side of the universe as seen from Earth doesn't "completely disappear" either.
Yes, and if a photon is reaching Earth from the edge of the known universe, it's not just Earth's gravity well that it's dealing with.
