Those who flew watched over the ones who had their wings broken.
The method of gaining knowledge of the below.
Space-time separation, therefore allowing for manipulation of the mediums inducing a polarising effect.
Requires scales independent of laws of thermodynamics. Mental concentration at high level for simultaneous induction of wave function collapse held long enough to sense quantum entanglement throughout the multiverse. If enough quanta is polarised consciously, profound changes will be made in space-time. The effect is easy to observe, the trick is in registering the cause with subjective point of reference techniques, revealing the event timeline.
