A Theory of Relativity

In “Science Project of a Lifetime” (Feb. 24) I find that, after “four decades ... and $700 million,” Gravity Probe B “arguably has had more delays, cost overruns and cancellations than any other NASA scientific endeavor.” Also on Feb. 24 I read that, after “21 years and $6.9 billion,” the “Army Cancels Comanche Helicopter.” What is the matter with NASA that in twice as much time it has expended on this probe only about 10% of the cost of the Comanche?

I suppose that the varying amounts may serve to illustrate a different theory of relativity. If the probe proves successful, we may determine something of importance about Einstein’s theory, namely its truth.
