These are changes in the fine structure, which are unproven, and impossible to measure. The change would be 2x10^-23 percent a second. This is measurable over quasar distances, which are some of the most distant objects known. Light from them takes 4 billion years to get here, which means your statement is only proved by using objects much older than 7200 years.

But it theoretically opens the door, does it not?
