hydrogen bomb
C1Technical / Academic / Historical / Journalistic
Definition
Meaning
A nuclear weapon that derives its explosive energy from nuclear fusion of hydrogen isotopes, much more powerful than a fission-based atomic bomb.
A term often used metaphorically for any extremely powerful, destructive, or contentious thing; also, a central concept in Cold War history and nuclear physics.
