You are making things up:

The practical consequence of the butterfly effect is that complex
systems such as the weather are difficult to predict past a certain
time range - approximately a week, in the case of weather. This is
because any finite model that attempts to simulate a system must
necessarily truncate some information about the initial
conditions=E2=80=94for example, when simulating the weather, one would not =
be
able to include the wind coming from every butterfly's wings. Although
in all practical cases, deficiencies in the knowledge of the initial
conditions are more important source of error, as are model
deficiencies. In a chaotic system, these errors are magnified as the
simulation progresses. Thus the predictions of the simulation are
useless after a certain finite amount of time.

It originated from the chaos theory.
