| | ::::With all due respect, relativity was factored into the design of the GPS satellite system. If you want to calculate the energy release of an atomic bomb, E=mc<sup>2</sup> is very useful. We don't know with great precision the speed of light, and we don't know with great precision the value of "c". But God gave us brains and curiosity, so we will learn more precise values for both. So far, they match. If someday in the future, someone calculates "c" and measures the speed of light to more decimal places and discovers that they are different, I will have an open mind as to why. The constant "c" carries through consistently in Einstein's calculations for the Special Theory. The coincidence that "c" happens to equal the speed of light is one of the beautiful things about God's universe. Although I do not spend my life's work on theoretical physics, I am pleased that God has inspired some very smart people to devote their lives to thinking about relativity, and I wish them success and happiness.

| | + | :::::We've discussed the claim about relativity and GPS over and over on this site, and as a matter of historical fact (not to mention obvious engineering efficiency), theoretical relativity was not part of its design. It is far easier and more accurate simply to synchronize directly based on observation, as may be needed.--[[User:Aschlafly|Andy Schlafly]] 11:20, 12 November 2012 (EST) |
