Some articles on atom:
... The test is based on the following principle When an atom transits from an excited state to a base state, it emits a photon with a specific frequency and energy ... When an atom of the same in its base state encounters a photon with that same frequency and energy, it will absorb that photon and transit to the excited state ... frequency and energy is different by even a little, the atom cannot absorb it (this is the basis of quantum theory) ...

“All you of Earth are idiots!... First was your firecracker, a harmless explosive. Then your hand grenade. They begin to kill your own people a few at a time. Then the bomb. Then a larger bomb, many people are killed at one time. Then your scientists stumbled upon the atom bombsplit the atom. Then the hydrogen bomb, where you actually explode the air itself.”
