ELI5: Why doesn't stomach acid eat through your stomach when you die?
gpt
When you are alive it eats through your stomach lining, but your body is constantly replacing that lining.  Your body is also producing more acid, because acid doesn't stay acidic forever - when it "eats" a ~~lower~~ higher pH substance the acid's pH is ~~lowered~~ raised.  Acids and bases cancel each other out and become water + salts.

When you die, you stop producing lining and also stop producing acid.  The acid in your belly gets "used up" on the existing lining/surrounding tissue and doesn't burn a hole through the floor like Alien.
