Hi! How can I calculate the time dilation of an object in a gravitational field relative to an object that is not experiencing gravity? Would I be able to use the gravitational time dilation formula if I only knew the gravitational acceleration that I was experiencing and "my" time? Thank you for your help!

Answer 1:

This is another question that requires general relativity to answer. The short of it is that something which is in a gravity well will experience time dilation relative to something outside of that well. This is actually needed for GPS to work accurately: here on Earth time passes ever-so-slightly more slowly than it does for the satellites in orbit. Again, you need some pretty advanced math in order to even touch general relativity quantitatively, which I as a biologist never was exposed to.
