there doesn’t appear to be enough physics we don’t know to allow for anything else
until we do! (my admission that we hopefully have so much more to discover).
however, the issue at hand is the here and now. we have theroms that describe what we know to be theoretically possible - but those are far and away from what we think is possible now, e.g. LK-99… AFAIK, there is nothing that says we cant have RT/AP superconductivity, but did we really just make a breakthrough?! (hopeful, fawning sounds)
we do still have to deal in what we currently think of as “reality” and things like FTL and the tech required for alien visitation are way outside of our current understanding - to the point of being magic. surely no one should accept “magic” as an answer to a serious question on possible alien visitation.
