In 1949, the cold war became a nuclear arms race when the Soviets detonated an atomic bomb. United States military and ...

After that point, the process spurs an explosion. You can think of it like a hydrogen bomb. Such explosions are called nova, and they are relatively common throughout the universe. In fact ...

One of the more infamous and potentially catastrophic episodes of the U.S. nuclear program during the Cold War occurred in ...

In theory, a hydrogen bomb could use more than two stages — the explosion from the secondary stage could be used to ignite fusion in larger amounts of fuel in each subsequent stage. In fact ...

They certainly got it independent of us. Look, the Soviets made their first atomic explosion in 1949. That set off debate on the Hydrogen Bomb, on which we had done little serious work for a long ...

A fission bomb is therefore used to detonate a surrounding mass of hydrogen. The resulting thermonuclear reaction, as it is called, is self-propagating until the reacting mass is blown apart by the ...

But this bomb within a bomb is "boosted" by adding hydrogen gas to the center of the core, making the fission explosion more powerful. That enormous power is essential to igniting fusion in the ...

The Castle Bravo hydrogen bomb test on March 1, 1954, produced an explosion equivalent to 15 megatons of TNT, more than 2.5 times what scientists had expected. It released large quantities of ...
