How Big Would a Nuclear Bomb Need to Be to Destroy Earth? 😳 | My Reaction

How big would a nuclear bomb have to be to destroy Earth? In this short 3D reaction video I watch a wild “what-if” scenario and break down why destroying an entire planet is WAY harder than it sounds — and why this is purely a theoretical thought experiment. 🌍💥
In this video:
• My reaction to the claim that a bomb could end Earth.
• A high-level look at the science behind planetary destruction (no instructions or technical details).
• Why nuclear weapons are devastating but not “planet killers.”
