But does it? This is merely one entry in a long line of evidence consistent with the prediction. Wouldn't it be better to say it did not falsify the prediction?

But does it? This is merely one entry in a long line of evidence consistent with the prediction. Wouldn't it be better to say it did not falsify the prediction? If this had not been consistent with the prediction, the precession of Mercury still was, so then one needs to sort out what that means. Was one of the experiments flawed? What's the statistical certainty of each, etc. I don't see how a prediction can be proven true anymore than a theory can.
