Free radicals are unstable molecules that can damage cells by reacting with proteins, DNA, or membrane lipids. They form naturally during metabolism but increase during stress, illness, or toxin exposure. Antioxidants protect cells by stabilizing these reactive molecules. An antioxidant donates an electron to the free radical. This donation does not harm the antioxidant because it remains stable after the transfer. Once the free radical receives the electron, it loses its reactivity. It can no l

A viral video proposes a radical theory: mountains are not geological formations—they are the fossilized stumps of colossal ancient trees that once covered the Earth. Proponents point to "stone rings" on mountain slopes as evidence of ancient wood grain and cite petrified trunks as proof of a lost, planet-spanning forest. They imagine a world where trees reached into the heavens, and their remains became the peaks we climb today. Mainstream geology firmly rejects this. Mountains are built by tec
