## Which is stronger a hydrogen bomb or a nuclear bomb?

All of this, in both cases, happens in a small fraction of a second, but the end result of a hydrogen bomb is a dramatically higher energy output from the nuclear fusion at the very center of the reaction, up to a thousand times the explosive yield for a device of the same size. Thus hydrogen bomb is more dangerous.

## How many tsar bombs would it take to destroy the world?

16,000And finally, the Tzar Bomba—the largest nuclear weapon humanity has ever concocted. A real doomsday device. “Only” 16,000 would toast the whole planet. Of course, none of these figures take fallout and other atmospheric effects into account—just square mileage blown away.

## How many tons of TNT is a supernova?

“supernova explosions give off about 10 44 joules of energy, which is about ten octillion (10 28) megatons of TNT.” the Little Boy (Hiroshima Bomb) was about 15 kilotons. so the average supernova is about 67*10 28 (670,000,000,000,000,000,000,000,000,000) times more powerful that the first atomic bomb.

## Could nuclear weapons destroy the world?

But assuming every warhead had a megatonne rating, the energy released by their simultaneous detonation wouldn’t destroy the Earth. It would, however, make a crater around 10km across and 2km deep. The huge volume of debris injected into the atmosphere would have far more widespread effects.
