the proof lies in the report on the Japanese experiments of the most perfectly darkened room ever, in all radiative ways..and then remote viewed by psychics to read a placard on one wall.
when the remote viewers were in this test room, the sensors would take in an increased average of 15,000 photons of light.
I believe it was David Wilcox, in his new book and lecture, that presented this corroborative evidence.
So, the aether sonar ping from the pulsed xenon gas of the flash.... and thus the emitted return light of the local flow through (both ways) wormholes.
