Question from an amateur:(adsbygoogle = window.adsbygoogle || []).push({});

I often read that Quantum Theory can explain very accurately the very small but not the big, General Relativity very accurate for the big but not for the very small.

How "wide is the band" in which both overlap, being both accurate?

i.e how big is the size of things which can be accurately described using any of both?

or perhaps in more technical words, how much do we have to "turn the parameter knobs" in each of them so that they start yielding incorrect solutions?
