Schumann Resonance 20/6 14:00 Around 10:30 UTC, after approximately 28 hours, the data returned to flow and the academics decided to cancel all data prior to the blackout; if we had wanted to bet on what mainstream “science” would have shown us, we would have had no doubts about betting on the denial of phenomena that do not fit into the “academic” narrative. What we are shown are the frequencies all at very low levels, it can be seen that all the base values are off the scale. The reported Amplitude is however still quite high, the maximum, as soon as the data came back, was Power 43 in descent, this confirms without a shadow of a doubt that before the darkening, coincidentally, the values were very high. It will not be sufficient to have deleted the data to cancel the event.
