One cannot understand anything "a" that is not known, and, if as stated, knowing a thing such as "a" is clearly beyond human capability, yet "a" exists, then logically it is false assumption to claim that understanding everything could possibly be achievable, for the simple reason that "a" exists yet is not known.

As to the OP question, perhaps someday humans will know "everything" via science, but, because Science is defined as Uncertain Knowledge, even knowing everything scientifically does not mean that the knowledge is without limits. Just consider the HUP--does anyone claim a way to have precise knowledge of both position and momentum of a quantum entity at a moment in time ? If you want certain knowledge of anything, then you must use a means other than science--by definition such knowledge is impossible via use of scientific thinking.

The important distinction for rational discussion of science is between "certain knowledge" and "uncertain knowledge", only the second is possible via science. Understanding is after the fact of knowledge, first must exist a thing "x" that can be known, then enters the question of how much of the knowledge is understood.
