Thanks, Derb. You not enabled me to get my mind around relativity and Gravity B–and provided considerable pleasure in the process.
A final couple of questions:
a) The Gravity B experiment is apparently going to cost us taxpayers just shy of a billion dollars. Given that Einstein’s theories have already proven accurate at a very high degree of precision, are the results of Gravity B likely to prove of any practical use? (Feel free to construe “practical use” in any way you like, by the way. What is and isn’t of “practical use” is, in a way, the whole question.)
b) Do you suppose private funding of such research might prove possible? Or is Gravity B an example of the kind of research that, absent enormous public funds, simply won’t take place?
