These odious matters being left to putrefy in the close and heavy air, emitted an insupportable stench, to which every court and passage poured forth a contribution of its own.

The theory of operation on which Hieronymus Machines are based is that all matter emits a kind of "radiation" that is not electromagnetic, but exhibits some of the characteristics of both light and electricity.

Neutral atoms or condensed matter cannot emit EUV radiation.

Some black holes have more matter around them and the matter falling in emits more x-rays for longer.

If prevailing cosmological theory is correct, nearly 99 percent of the universe is unobservable because the matter emits no radiation at all.

Because hot matter near a black hole also emits X-rays, Dr. Tod Strohmayer, an astronomer at the NASA Goddard Space Flight Center, said, he was able to deduce the black hole's spin from the extremely rapid oscillations that he discovered in data gathered by NASA's Rossi X-ray Timing Explorer Satellite.

Calorescence is a word for when matter absorbs infrared radiant energy and emits visible radiant energy in its place.

All matter emits electromagnetic radiation when it has a temperature above absolute zero.

Semyon Davidovich Kirlian-inventor of Kirlian Photography, discovered that living matter emits energy fields.

Weak nuclear forces are the forces that cause radioactivity, or when matter emits energy.
