Take any 100 of these incoherent light waves and they produce the light of 100 separate waves. Because of this the light from your lamp is bright enough for you to read the book in your lap, but not nearly bright enough, say, to reach the moon. On the other hand, if those random light waves are made coherent so that the peaks and valleys of each wave are in step with each other, then the intensity of the light waves becomes far greater than when they function separately. Their intensity is proportional to the square of the actual number of waves. Take those 100 light waves again, make them function coherently together, and they will produce a light as bright as 10,000 incoherent light waves.
Coherent light is called laser light.
It can be bounced off the moon, applied to conduct surgery, or used to play a laser disc recording. Scientists said it could happen only if consciousness, experienced in its self-referral state during Transcendental Meditation, is a field and only if it is the same unified field that underlies all of nature. This is because on the level of the unified field, everything in nature is connected. Researchers predicted that if a group of experts in the Transcendental Meditation and TM-Sidhi program could, in fact, produce an influence of coherence on the level of the unified field, then according to the behavior of fields, that coherence would spread throughout the environment. That's the hypothesis.
