I don't know much about it but from what I've read imagine that we are inside a black hole. Every black hole is a universe of its own. The boundary of the black hole is the outer boundary if we are inside it. From the outside it would be just the surface of the black hole. Something like that perhaps

Should be verifiable on the inside with stuff popping up at the boundary, right?

When I read these quantum articles I think it's might as well be mambo jambo. Are the fundamentals of quantum physics even falsifiable?

What do you mean by “the fundamentals of quantum physics”? If you’re talking about phenomena like superposition and entanglement, the answer is absolutely yes.

First observations of quantum physics was that if you light through two slices of holes in a paper it makes more than two marks on the wall behind it - this proves that the light is some kind of a waveform or could act like one. As far as I know the fun starts when you try the same experiment with exactly one photon emitted. The single photon will simultaneously go through the two hole. This caused some confusion and we now call this phenomenon and related things "quantum". But thid is just my understanding based on a book, other commenters seems to be much more knowledgeable about the topic.

The single photon registers in a single spot on the screen, as a particle should, and so there's no problem with assuming that it went through one hole or the other.

The fun starts when you start sending single photons through the holes one by one - again, every photon registers in a specific spot; but when taken in aggregate, those spots form the same interference pattern as with multiple photons.

The boundary would likely appear to be infinitely far away, and so you could never see it actually happen.

I really liked cosmological natural selection of Lee Smolin in that regard. For me it's just looks so simple and obviously. https://en.wikipedia.org/wiki/Lee_Smolin#Fecund_universes
