The results seem to disproves both:<p>1. A quantum foam space-time.<p>2. A networked&#x2F;graphed space-time in which the nodes can have plank-scale (or larger) movements and re-arrangements.<p>But I&#x27;m not sure if this experiment disproves a space-time of <i>fixed-position</i> nodes which have additional properties (such as a field of scalars &#x2F; vectors &#x2F; spinors &#x2F; etc).<p>To test the above I think measuring the smallest possible change-of-angle that a laser can make off a reflective surface (compounded X times) would do well. If the arrangement is as above, rotating the reflective surface by the smallest amount will affect the produced angle in a non-linear way (compared to larger amounts).
