You have an observational slice of about 4000 years at the most generous, 400 years more leniently (telescope invention was ~1600s), 40 years for modern tools (OAO-2 in the late 1960s).

You might as well be looking at a single frame of a movie and telling me you know the whole plotline because it happens to have the same pixels on screen for the whole shebang.

But that specific frame has all the previous frames imprinted and increasingly faint in some sort of cosmological motion blur.
