Here's what it responded with (note - errors with copy/paste formatting fixed):
Thoughts?
The problem is that you don't understand the answer.
ChatGPT got this right, but it isn't a mind-reader. It has no idea what you "really meant" with your question. It is explaining that when going through a gravity well, light changes frequency and bends in the curved spacetime. It doesn't mean it "keeps" that frequency shift when it comes back out of the gravity well.
Perhaps I don't understand the answer & who is a mind reader? I've stated, on other forums, that I myself am not a mind reader & I take it you're not a mind reader, either?
Anyhow - 2 things:
1. Is it your contention that we (our galaxy, solar system, Earth) is neither in a gravity well nor in some sort of similar effect (some sort of gravity wells within gravity wells arrangement)?
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:
Quote:Yes, the redshift due to a gravity well, known as gravitational redshift, persists even after light leaves the gravitational field. Gravitational redshift is a consequence of the warping of spacetime caused by the presence of mass and gravity. As light travels through a gravitational field, its path is affected by the curvature of spacetime, leading to a change in frequency and wavelength.
The formula for gravitational redshift (z) is given by:
...[same as before]...
This formula indicates that the redshift is directly proportional to the mass of the gravitating object and inversely proportional to the distance from the object. As light travels away from a massive object, the gravitational redshift decreases with distance, but it doesn't completely disappear.
The concept of gravitational redshift is an integral part of general relativity and has been experimentally confirmed in various settings, including observations of light from stars passing close to massive objects like the Sun. The redshift observed in such scenarios remains present even after the light has left the gravitational field.
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.
