**Acknowledgements**

I am indebted to Hal Fearn, Daniel Kennefick, Josė Rodal and Nader Inan who participated in Zoom calls every few weeks for the past several years where the nature of inertia in general relativity was the topic of focus. At times, the calls were supported by a NASA Innovative Advanced Concepts Phase II grant. The experimental work reported here was done in collaboration with Hal Fearn, Michelle Broyles, David Jenkins and Paul March. I am also indebted to Gary and Anne Hudson, and Robin Snelson of the Space Studies Institute, and the Department of Physics at CSUF for ongoing support for many years.
