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.)
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.
