We know some laws of physics. We do not know them all. (We can prove some of them.) We can use what we are sure about to make up theorems which go beyond what we know how to prove.What is meaning of "extend beyond the proof" in the following sentence, please:
But while we do not know all the laws, we can use some to make guesses at theorems which extend beyond the proof.
From "The Character of Physical Law," by Feynman.
