hydrogen bomb
An extremely destructive bomb whose explosive power is derived from the energy released when hydrogen atoms are fused to form helium. This atomic fusion reaction is the same reaction that takes place in stars like the Sun, where the pressure of gravity forces hydrogen atoms to fuse; a hydrogen bomb uses the force of an atomic explosion (the fission reaction exploited in atomic bombs) to compress the hydrogen to the point where fusion takes place. Hydrogen bombs are many times more powerful than atomic bombs.
