I totally agree. There is always some error. If you are constructing the mirror for the new space telescope it must be very minor. Nevertheless, the mirror will inevitably contain some error.
We live in a flawed, imperfect reality. This implies that a perfect reality could exist. A reality where physical error does not exist and cannot exist.
