Having observed all-things?

It sounds like the name of a star trek episode.

The point being made is that we rely heavily, almost entirely, on what we observe of space-time, to then formulate it's (presumably) definitive laws of modus-operandi.

Yet, when we observe, and then correctly construct a theory of what we observe of space-time, and then join all those theories based on our observation, what we ultimately CAN be left with is a purely mathematical description of space-time, as though, "as though", we no longer need to "observe" reality, we can "explain" it mathematically.

What would become of our ability to "observe" space-time in having a fully-operational mathematical "theory" of space-time?

I am thinking we would need to incorporate "into" that theory, ultimate theory, of space-time, a theory for our ability to "observe" space-time.

Any thoughts on that from anyone?

I think the point being made is, is that if we are to be entirely realistic with foresight in the quest for a "theory of all things", should we not soon begin to consider equating into our mathematics the actual "mathematics", if not logic" of our perception ability?

Would that not be the wise thing to do?
