"Finite" makes simpler theories, yet, nature doesn't care. Can't have "continuous" without "infinite". Neither is falsifiable: science doesn't say, yet mathematics isn't merely science. Many have said finite, they've always been proven wrong.

A usual account of mathematical ideals then has besides straight lines and perfect circles also the origin, and "point at infinity", accessible to the mind. So, it's mathematics that _owes_ physics more and better mathematics of the infinite.

One of Einstein's quotes about "there are two things infinite, the universe and stupidity, not sure about the universe", may make it so that somebody with infinite stupidity simply has an infinite universe, also. So, it's unfortunate that that's the most well-known quote about the infinite in physics. Yet, anybody who says "Universe" automatically invokes "Infinity". Then, lesser accounts are usually enough given to be talk about "Worlds". Anyays retro-finitists and reductionists of the partial variety: they're wrong (or ignorant, which science won't have, since "The Science" includes _all_ the data). So, Fritz London is a great sort of physicist. About continuity and infinity in the 21'st century, well, there's me, ....

The universe does not seem to care whether it makes sense to us, just think of quantum theory! But I think before modern cosmology, people often imagined finite spheres around the world. Since everything you have ever seen is finite, it would be natural to assume that everything is finite. Infinity belongs to math, not physics, and there it could be seen as a kind of simplification. Camille Flammarion seems to have imagined that the dome with the stars has an edge, so is finite, beyond which is the world of the abstract laws guiding it (my interpretation). (The Flammarion engraving shows a traveler who pokes his head and shoulders through the star-studded "firmament" [the solid dome of the sky]. By doing so, he looks out at the wondrous cosmic machinery, swirling fires, and suns of the Empyrean realm beyond. [Though many people mistake it for a Renaissance-era woodcut from the 1500s because of its antique style, its historical origin defi- nitely dates back to 1888.]) In general relativity, you cannot look at coordinates to measure physical lengths, but must instead use the metric tensor. Near a black hole's event horizon coordinate-lengths can become infinite while the physical length according to the metric remains finite. Conversely, true physical infinities in the metric do occur at the central gravitational singularity.

The theories of your bunch of idiots and the universe are not quite the same, even if both don't care about having any sense.

Is our universe just a fractal order...or the n-dimensional equivalent of a 'Klein bottle'? After all, you can walk forever around a Mobius strip or the perimeter of a 'Koch snowflake' without leaving you house or reaching the end. The harmonic series sums to infinity and an asymptotic process never reaches its limit. Maybe there a simple answer like Newton's apple but which is beyond the ability of the human mind to understand. > Cheers

Sometimes people say "Stern-Gerlach proved discreteness of the quantum", other times people say "Stern-Gerlach proved continuity of the quantum". People who say "continuous" have a model of "particles" as a conceit, like Einstein, people who say "discrete" have a closed world with no straight lines, right angles, or perfect circles (since the Planck length square its diagonal would be ir-rational). Then about something like "continuous quantum commutators" for the commutativity (and lack thereof, and the reduction) since Born's account of QM, then besides Reichenbach's account of relativistic QM for "Schroedingerians" like relativity has "Lorentzians" for "invariants" about "measure" and "the measure problem", besides Zitterbewegung and the tritterionic and super-symmetric flux and so on, "Born's infinite self-energy" never went away, and people who think it did are mistaken. Then in mechanics and "black holes" as "gravitational singularities" and otherwise the "naked singularities" and "cosmic censorship", well, like magnetic monopoles and otherwise accounts of singularities in a singularity theory, singularities in a singularity theory are branch in a multiplicity theory, then for "running constants" and so on, since as science has grown that it knows that particles get smaller and the universe gets larger (and millions of years older), every few years. Wertheimer has a pretty cool account of "space inversion", as does for example Graustein with "higher geometry". Of course art and drawing has known perspective and "point at infinity" since forever. Then these days there are "Cosserat continua" and so on, about Poincare's rough plane after Euclid's smooth plane, and about the Zollfrei metric for relativity, and that "there are everywhere closed infinitesimal time-like curves" while yet "there are nowhere closed finite time-like curves", then that usual accounts of "nulls" like "null geodesics" are half accounts of those openings/perestroikas/catastrophes. Physics has had at least several crises since the ultraviolet catastrophe, and physicists like Rutherford and Fermi known it's a continuum mechanics for nuclear and solid-state physics. It's a continuum mechanics, ....

A "finite universe" stops making sense when "physics is an open system".

When I was a boy I used an analogue computer and an analogue phone and I listened to analog music. I made analogue measurements...but I spent digital money on digitally sized clothes. Nowadays, just about everything has gone digital. Why? Probably because digital is the natural and more efficient state. That's why there is sand on a beach rather than one massive crystal. Nature went digital years ago. 'Digital' is unlimited.
