Physics is not anthropocentric. The mass of an electron or the speed of light do not depend on the species measuring it. While it is possible that life might exist in more than 3 dimensions and be able to protrude into our spacetime (at least, there isn’t anything prohibiting it), I can only imagine such intrusions would be much weirder than the average UAP. Furthermore, we are venturing so far into speculative terri…
No, but the idea of a totality of physics is: that there's nothing outside it that we don't understand. That's very anthropocentric. And heard in the dismissals people give of possibilities or observations that "violate a law of physics". There are some pretty weird stuff out there outside the average UAP cannon — of metallic orbs, cigars and clamshells — that may qualify as your intrusions; good word! Science lives…
