This is one of those things which prove that thought experiments often give you a very inaccurate expectation even when there is no way to prove it wrong and there is some logical consistency. In reality the heat required to cook a pizza needs to be within a certain temperature range for a sufficient duration of time. You can never cook anything with any kind of explosion, ever. But the fact is when you first heard this you thought for a second "huh, that kind of makes sense" and there are people who literally believe that under the right conditions this would actually happen. Literal professors and college students. While this is a thought experiment is easily disproved, all thought experiments suffer from this same kind of blind acceptance. the "if it makes sense it must be true" fallacy. But what makes sense to you is horribly disfigured by your biases, you experiences, and your ignorance.
