With this new information, it is possible to view ordinary light from a different perspective. "Any identical portions of light beams can (and will) reflect from each other." <br clear="none"></div><div id="yui_3_16_0_1_1439609808422_5187">An example of this can be demonstrated by an introductory-physics device (Newton's cradle, <a rel="nofollow" shape="rect" target="_blank" href="https://en.wikipedia.org/wiki/Momentum#Conservation">https://en.wikipedia.org/wiki/Momentum#Conservation</a> ). Only if equal numbers of balls are dropped simultaneously will there be reflection of the same number as the input. If unequal numbers are dropped simultaneously, then it would appear that the larger number of balls is transmitted thru the set of balls. No one would say that the balls travel thru the stationary balls. Momentum reflection is the obvious answer in this case - and in the case of light. <br clear="none"></div><div id="yui_3_16_0_1_1439609808422_5192">Had Dowling remembered this demonstration, he would have been able to say with absolute authority that light can reflect from light. The appendix of our paper is a mathematical proof of the null-momentum point in the center of the 'dark' zone for equal waves. This is the wave equivalent of the equal-particle demonstration.</div><div id="yui_3_16_0_1_1439609808422_5191">My task for the next conference may be to demonstrate how this reflection effect affects the photon structure within the electron.</div><span class="yiv1131972355HOEnZb"><font color="#888888"></font></span><div></div><div id="yui_3_16_0_1_1439609808422_5190">Andrew<br clear="none"></div></div>
