Electromagnetic radiation (or "extreme") ultraviolet. UV, with X-ray and gamma radiation, are referred to as ionizing radiation due to the ability of photons of this radiation to produce ions and free radicals in materials (including living tissue). Since such radiation can severely damage life at energy levels that produce little heating, it is considered far more dangerous (in terms of damage-produced per unit of energy, or power) than the rest of the electromagnetic spectrum. The heat ray is an application of EMR that makes use of microwave frequencies to create an unpleasant heating effect in the upper layer of the skin. A
The Xi Effect that his theory about the so-called Xi Effect may explain their observations. The Effect postulates a vastly higher order of space-time called Xi-space, which has altered, causing slowly increasing effects on the local universe. These effects will cause galaxies to collapse and shrink rather than recede as they normally do. Eventually, the theory is proven as it becomes fact, and the shrinkage become measurable. Electromagnetic radiation is progressively eliminated and even colours begin to disappear. Darkness falls upon the Earth and there is total panic. The story bears some resemblance to Isaac Asimov's short story Nightfall. The Xi Effect The
