Get used to it.
Those things are true, what I wrote: nothing more, nothing less.
No, transfinite cardinals aren't used in physics, and it would be of
general interest if they were. And yes, physics needs mathematics of
infinity, and transfinite cardinals don't seem to be it. And real or
continuum analysis today uses countable additivity to get results. In
physics, transfinite cardinals aren't around, not for lack of
Cantor's antidiagonal result can simply be seen as that the line can't
be drawn by placing its points out of order. Because, only when they
are arrayed in their natural order, it doesn't apply.
And the Universe is its own powerset. And, it exists, because it
