All very interesting, except there was not a void 'found' in the Great Pyramid at all. Only an anomalous signal, the cause of which remains unclear.
This initial hypothesis has not been confirmed or verified at all, and there are a number of problematic issues with the hypothesis, as well as plausible alternative interpretations of the data collected.
