Nuclear Weapons
Nuclear weapons harness energy from nuclear reactions, primarily involving the splitting of atomic nuclei (fission) or the combining of them (fusion). In fission bombs, heavy elements like uranium or plutonium are split apart, releasing massive amounts of energy and radiation. Fusion bombs, often more powerful, combine lighter elements like hydrogen under extreme pressure and temperature, mimicking processes in the sun. Both types produce deadly radiation, strong shockwaves, and long-lasting environmental effects, making them immensely destructive. The science behind them involves radioactivity, where unstable atomic nuclei decay and release energy, crucial to understanding their power and potential consequences.

Nuclear weapons are powerful explosive devices that release energy from nuclear reactions, either through fission (splitting atomic nuclei) or fusion (combining them). They produce massive blasts, intense heat, and radiation, causing widespread destruction and long-term environmental damage. Developed during World War II, they changed global politics, as their potential for catastrophic damage led to deterrence strategies, where countries maintained arsenals to prevent conflicts. The existence of nuclear weapons raises concerns about proliferation, safety, and ethical implications, prompting international treaties aimed at reducing their numbers and preventing their spread.
