Now, How Perfect Is That?

Determined to be determined,
More exacting explanations
Of entropy approach the sphere
Of perfect circularity.

Mathematically it can be
Shown that quantum entanglement
Means information cannot change
The same way in the same context

Twice, which means two-way equations
Nonetheless can never go back,
Or something like that, some juggling
Of the beautiful balances

To reprove over and over,
That whatever has happened must
Have actually happened and can
Never not have happened again.
