Explaining the Un-explainable

I just had to note this...I don't understand the science of it but somehow it makes sense to me. He is writing how Einstein's realization on the nature of relativity explained the previously UN-explainable orbit of Mercury (who knew? Not me.)

In other words, in that November hour one hundred years ago when Mercury dropped out of his math, he alone of all humankind knew the universe was not what it had seemed for centuries. That’s the reason his moorings snapped, however briefly. As he later wrote, to do such work, one feels “akin to…the religious worshipper or the lover; the daily effort does not originate from a deliberate intention or program, but straight from the heart.”
