Once you get to the pdf file you have a printable file with no reference
points back to the original file. If you have a particular sequence of
text there are almost an infinite number of ways that it could have been
created. Indeed it could have been created in pdflatex, pdftex, Context
etc. or possibly in a non-TeX typesetting engine. 

You can follow this technique: reduce the pdf file to plain text using
some utility and then typeset it all over again. But you lose all the
formatting, font selection etc. 

Fear of changing an existing scientific paper has nothing to do with it.
You cannot back up from a pdf file into InDesign or Quark either.
Creation of a pdf is essentially a one-way street.
