I've often told people that we don't know enough about physics to say for certain that UFOs can't reach Earth. Our "advanced" technology is just a wee bit over 100 years old; and, only since WWII has it advanced in spectacular ways.
I really don't think we have a clue about the way things REALLY work.
I agree entirely.
And even less of a clue about . . . spiritual dimensions,
n dimensions etc.
Hmmmm....that was somewhere around 1947 wasn't it? Just sayin'...
