Have they tested for static field causing variations in response?
I don’t know. From what I have read (and understand very little) they keep theorizing as to why and how it works but no matter how hard they try to make their theories stick they all just fall apart.
I’m wondering if there is something on the quantum level that is happening that makes the explanation of how and why they work defy conventional explanations.
The energy creation was when one of the observers farted!!!
