I am fascinated by the does-not-compute public reaction to the US disclosures on UFOs.
Personally, I am comfortable not getting my head around it. I very much doubt my perceptions of reality, or that there is such a thing, in the way we like to imagine it. I expect that "simulation" is an inadequate way to describe or comprehend the nature of what we perceive, but I suspect there is something there.
It is interesting to think that the influence of the observer is not restricted to quantitative quantum-level phenomena and individual consciousness, but applies to collective consciousness, and might be more qualitative.
I know that sounds scientifically heretical, but I am not sure it is.
If you haven't read Schrödinger's What is Life? I suggest it.
