Kelvin says "infinite".

If zero exists, infinity exists.


"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.

Both makes perfectly sense: if one is true then the other is false.
But both are something that we cannot imagine. We cannot really
imagine anything infinite, nor a finite unverse that as no edge,
nor an edge of the universe, nor non-existence of any universe.

Oppositely, both have no.
You can assert  this or that - no conclusions,
no consequences, no significance.

There are other dogmas than "can't comprehend the infinite",
or "the total", or "the absolute", though of course for
mathematics it involves the paradoxes of identity, induction,
quantification, _infinity_, and continuity.

Then, the "super" natural is still "super" natural, about
the ineffable, or the omni, or the supreme, also.

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.

Kelvin is pointedly clear in his opinion "can't not be infinite",
then for example for accounts like Fritz London, who is a great,
with super-fluidity then super-conductivity, then often usual
accounts of the "super" like super-symmetry, basically are
reflections well enough on space-inversion (which is the
inverse of the segment of the radius), about the hyperbolic
(x = 1/y), and so on.

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, ....

Think of the border of, say, the Mandelbrot set, or any fractal. For 
some fractals, the "set" from afar is finite indeed. But, try to zoom in 
on a border... Its infinite indeed... ;^)

Some fractals you can zoom out forever, and zoom in forever.

when you zoom in forever where do the boundaries go to? 


beyond your computer monitor to another dimension??

 a dimension not only of sight and sound but of mind; a journey into a
wondrous land whose boundaries are that of imagination. Next stop … the
Twilight Zone

infinite...numbers
are all in the mind.

projected infinity.

Have you seen the writings of a crazy persron? It's infinite crazy...


it gets smaller and smaller and smaller

  I am not able apply to idea of "to make sense" to the universe here.
  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.

And since it doesn't - an idiot physicists
will also not care whether his moronic
mumble has some sense or not. Logical,
isn't it?

Good question...and there are many more. In particular, "how can 'energy' 
be infinite?" How can energy exist at all? Is the physical just a 
mathematical possibility?  Does there have to always be a beginning and an 
end? Or is the whole show just psychological, like 'colour'? 
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.

If you've studied quantum mechanics then you'll be familiar with
something like "Born's infinite self-energy" and about "Feynman's
renormalizable theories".

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, ....

For more of what I say, there's some hundreds lectures on
my YouTube channel talking about: reason, logic, mathematics,
science, and physics: particularly for a paleo-classical and
post-modern account that's super-classical and quite modern
for _infinity_ in mathematics and _continuity_ in mathematics,
for example about "the measure problem" and "the re-Vitali-ization
of measure theory" which demands an account since "Zeno's moving rows".

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.
