Ethan I love this article for a few reasons. It is well written and full of the information we know so far. The title ends with a "?" mark which leaves open the door to what we know to be true: At a future date we will know more about protons than we do at this time. Thirdly you put parenthesis around the word "uncuttable" which to me leaves open that there it is some uncertainty as to what is even there to be hypothetically "cut" , what it means (as a word) to even "cut" and the possibility that what we think is "uncuttable" at this time may eventually be found to have possible different states than what we now postulate.
