Could nuclear bombs cook pizza?

TL;DR

A nuclear pizza would not be properly cooked because a nuclear blast delivers extreme heat for too little time. One estimate placed a 10-inch pizza about three miles from a one-megaton blast, but that location is inside the blast-wave radius. Cooking needs heat applied over time, while nuclear-weapon heat lasts less than 10 seconds on average. Read on to see why the meme’s calculation fails.

who's ready for hell's kitchen night i hear that gordon gets angry in this one yeah okay fantastical i have the pizza here i'm gonna pop in the oven and i'm just gonna leave it for three kilometers outside of a nuclear blast that that's weird that doesn't sound right aria where'd you get these instructions some guy on reddit of course you did of co...

Key Insights

• 🥵 Nuclear detonation involves vaporization, fireball formation, and shockwave propagation with intense heat.
• 🥺 Cooking enabled early humans to access essential nutrients leading to brain development.
• 🥵 Materials near a nuclear blast experience intense heat but may not sustain flames.
• 🙈 Internet memes suggesting impractical cooking methods often ignore realistic constraints.
• 🥵 Time plays a crucial role in heat transfer and cooking processes.
• 🧑‍🍳 Applying gigajoules of energy in a short time frame damages materials rather than cooking them.
• 🧠 Cooking is a milestone in human evolution contributing to brain development.

Questions & Answers

Q: Can a nuclear pizza be properly cooked by a nuclear blast?

No. Although a nuclear blast can deliver enough raw heat energy, it releases that energy too quickly to cook a frozen pizza properly.

Q: How far from a nuclear blast would a pizza supposedly cook?

One calculation placed a 10-inch pizza about three miles from a one-megaton blast. That distance is inside the blast-wave radius, so the result ignores whether the pizza would survive or be safe to retrieve.

Q: Why does the nuclear pizza calculation fail?

The calculation can estimate the heat needed to turn a frozen pizza into a cooked one and relate that energy to weapon yield and distance. It fails because it treats total heat as sufficient while overlooking how quickly the energy arrives.

Q: Why is time important when cooking pizza?

Cooking depends on how heat is applied over time, not only on the total energy delivered. Nuclear-weapon heat lasts less than 10 seconds on average, making it unsuitable for normal cooking.

Q: What happens immediately after a nuclear bomb detonates?

In under one microsecond, the bomb material, casing, and nearby air are vaporized into plasma measuring tens to hundreds of millions of degrees. The plasma radiates X-rays, which heat the surrounding air and form a rapidly expanding fireball.

Q: When does the shock wave follow a nuclear detonation?

The shock wave follows a few milliseconds after the fireball begins forming and expanding. This means a pizza positioned for the heat would also face the blast wave.

Q: How does rapid energy delivery differ from gradual heating?

A large tree may receive about a billion joules from the sun over 11 hours and tolerate it. Applying the same gigajoule of energy in a fraction of a second would damage the tree, showing why energy alone does not determine cooking.

Q: Why was cooking important for early humans?

A few hundred thousand years ago, early humans began applying heat to food, unlocking carbohydrates, sugars, and proteins that their digestive systems could not otherwise obtain from raw food alone. This supported the growth of bodies and brains, and some studies link cooking with the doubling of human brain size.

Summary & Key Takeaways

• An internet meme theorizes that nuclear blasts can perfectly cook frozen pizzas in a specific radius.

• Nuclear bomb detonation sequence involves vaporization, fireball creation, shockwave, and intense heat.

• Cooking is a crucial human discovery that led to the unlocking of nutrients and brain development.
