Light traveling in a uniform substance, or medium, propagates in a straight line at a relatively constant speed, unless it is refracted, reflected, diffracted, or perturbed in some other manner. This well-established scientific fact is not a product of the Atomic Age or even the Renaissance, but was originally promoted by the ancient Greek scholar, Euclid, somewhere around 350 BC in his landmark treatise Optica . However, the intensity of light (and other electromagnetic radiation) is inversely proportional to the square of the distance traveled. Thus, after light has traveled twice a given distance, the intensity drops by a factor of four.

Lightsabers are generally used for both offense and defense. A lightsaber can cut through virtually anything, from enemies to blast doors. The only ways to block the incoming attack of a lightsaber is with a weapon made with material that conducts energy, such as an electrostaff , Z6 riot control baton , some rare metals or simply another lightsaber. When used defensively, a Force-sensitive can deflect blaster bolts with a lightsaber, and with skill, can even reflect the shots back toward the shooter or some other target. Experienced Jedi can even employ their lightsabers to absorb Force lightning . Most practitioners use one single-bladed lightsaber, though some use double-bladed lightsabers or even multiple lightsabers at once.
