Our 'sight' or 'vision' is merely electrical signals interpreted by the brain. I am pretty positive just had a Space Force flyover here. My 'sight' was 'seeing' a plane/jet… but even my parentAnon… who is a disbeliever of anything 'odd' … said it looks soooo weird. I'm telling ya'… no sound. Low speed. The wings were not at the right angle. It was something else.
Secondly, If you dont think the tech exists to 'hack' our 'vision' to 'see' something different that what is actually there… think again.
