We would use a x-ray device by shooting x-rays (x-rays are electrons) at a fluorescent screen. Similar to how an electron microscope works, in order to capture beings by having more resolution & contrast, but mainly perhaps 4 dimensional electron imaging. I wonder how spatial time would affect the electrons if they propagate cubic.
The result is only in shades of black & white as known.
I know this, becuase I have seen some ghosts in my life, but it could have been a beamer scam, but I didn’t place a beamer in my room though.
We maybe indeed gamma radiation.
IF the electrons propagate cubic then it might show some clue about the 3-phase drawing, while we could optionally rotate. The drawing maybe moved partial into the fourth dimension.
