No, it can't. If you are willing to say that a cow can not jump over the moon, then a strong password can not be brute-forced, even though it might theoretically be possible for a cow to quantum-tunnel over the moon, and it might theoretically be possible that an attacker guesses your password. The probability is so vanishingly small that you would call it impossible in any other context.
