"But remember that an "angel" is anything that carries out a mission for God. This includes forces of nature. An angel doesn't have to be an intimidating, fiery being... Photosynthesis? That's an angel. Gravity? An angel. Magnetism? Angel. The Midrash in Bereishis Rabbah (chapter 1) says than an angel only performs one job. That job doesn't have to be destroying Sodom; it could be peristalsis, centripetal force or condensation."
