    If "no", in ZF, comprehension is fine, but, there are
    "bigger" theories than ZF what model the objects of
    ZF what the extra-ordinary character of the sets
    may so result in those "larger" theories, whether
    they're "weaker/stronger", and whether they're
    "conservative" or not, whether or not the transfer
    principle holds and with usual unrestricted comprehension
    arrives at a default usually that the infinite union is an elt.

    Here the sigma-algebra pretty much is a strong enough form,
    and, there are weaker forms yet still strong enough, what
    work up countable additivity for measure theory.

    About the "Kunen inconsistency" and a default element-ary
    embedding what relates the context as the complement,
    that basically any element v in the universe of pure sets V
    is more-or-less having "context" what also defines it V\v,
    makes for an element-ary conflation, in context.

    (That a thing is all the things it's not.)


    A usual counterexample of comprehension is "Russell Paradox".

    Is your cytokine response Th1-dominant or Th2-dominant and why is this important?


    "In an ideal sitution, neither Th1 or Th2 is displaying a more
    dominant position. However, in some people, a _prolonged_
    pattern of either Th1 or Th2 dominance occurs and this is
    where health problems begin." -- https://jameslilley24.medium.com/are-you-th1-or-th2-dominant-and-why-is-this-so-important-to-know-8efb050005a5

    If the Pfizer vaccine is a pretty well-designed synthetic-antibodies-bound-to-spike-protein-matching-epitopes,
    then it does seem like it would be OK and that people with usual
    immune systems when exposed to that would see there be worked
    up an immune response.

    It doesn't say then in the studies whether the people were
    actually exposed to coronavirus (and..., how much).

    A "self-amplifying mRNA" seems a bad idea.

    If I say something like a narwhal and eagle are related (because they're
    both animals) or a narwhal and a walrus are related (because they're
    both mammals), I'd be wrong. (It's a bad example because there are no
    other mammals.)

    The question of which one is older, or bigger, is more interesting.
    What's the oldest known thing, is the best known.
    "We are now living in an age of supergiants," said astronomer Paul
    Hodge, speaking of the massive stars that are getting ever bigger in
    their final phases before collapsing and ending as white dwarves.

    I know some things. I've got the answers to my questions. I can find
    things out. I can figure things out. The thing about the questions of
    what are the "answers" to the "questions" is that if they're the wrong
    answers, there may be consequences, like a car wreck, and there's no
    time for the car to swerve out of the way.

    What are the right answers?

    A "white hole" is a "black hole" going the other direction so the "hole"
    part isn't correct, the term's a metaphor like a "supermassive" star is
    a big star and not actually a black hole or a neutron star or a quark
    star. There is a theory that "gravitational waves" are "gravitons" what
    is a massless particle, so they travel at the speed of light and it
    takes a while, like years, for the gravity waves to make the
    observational effects, and it may be a "signature" of gravitons that is observed. There are no good reasons to believe that gravitons are real,
    other than, we'd like there to be such particles. In the quantum theory
    of gravity, a "particle" like a graviton would be a quantum excitation
    on a wave, and that would be the way of seeing it, and so it's a "wave".
    A wave is an energy density, so the question is whether that can have a
    zero mass. It can if there is a Higgs mechanism what makes the mass a phase.

    "Higgs Mechanism" is an explanation, in the "standard model", about the
    mass of things. It's a good theory. There is some debate over
    "supernovae". There's a problem in that "quarks" and other sub-nuclear particles aren't the only thing there are, there's the Higgs field,
    which is a kind of background "electromagnetic" field, and this is what
    gives a "mass" to the elementary particles and that the mass is a phase
    what's a Higgs field excitation. So a Higgs field excitation can move.
    It can vibrate. If a quark, or electron, is a vibration, and the Higgs
    field is a vibrating background, is the motion of the "wave" the same as
    the motion of the "field"? Does a particle's mass change over time and
    how is this important? How important is a quark's mass, relative to a
    supernova explosion, if there's an effect on a Higgs excitation what
    would mean a mass change.

    "Inflation" is an expansion of the Universe that happens after the big
    bang, and it's an ad-hoc theory. The question of whether an ad-hoc
    theory is "correct" is that if the ad-hoc theory has consequences, it
    would be good if it were confirmed, because, an ad-hoc consequence is
    just the same as the real consequence, in terms of whether it's "true"
    or "false". Is a "multiverse" possible? Is the universe the kind of
    thing it can "have parts"? Does the universe have "ends" in space?
    Does the universe have a "middle"? Can you go off in one direction from
    the "center" and eventually, not come back? What does it mean, if, in a
    theory, you have a "particle", but it has a 90 degree phase shift?
    Are we at the end?

    "End" means "limit", and, what does the limit look like, if it's an
    actual thing and not a metaphorical thing, like a "black hole". In the
    1920's, Einstein had a problem with quantum theory. He thought, since
    the Universe is made up of matter, a particle is an excitation on a
    field, like a sound waves and a pressure, so the particles have an
    oscillatory motion, and they have a period, and a quantum particle is an excitation that can be a vibration of a field. But there are fields that
    can be in two places at once, like an electric field, or magnetic field,
    and an excitation what can be in two places at once is something you see
    in a Higgs field, when you excite a Higgs field, so there's a vibration,
    like a "wave" and that is an oscillation, and so you can imagine that it
    has a "frequency". Einstein couldn't make the connection between a
    "wave" and a "particle". The answer was that the wave wasn't an
    amplitude, but was a "phase" shift, so the thing is, that if you imagine
    a "particle", a "quantum excitation" on a "Higgs field" or a "photon" or
    an "electron", the "excitation" isn't an excitation on a background, it
    is an excitation in a field. In the case of a photon, or an electron,
    the "excitation" is a quantum-excited field and the "frequency" is an "oscillation" what is a phase. If you imagine that an electron can "go backwards and forwards", the electron isn't the excitation, but the
    phase it has. And, the thing is, there's a "relativity principle" where,
    if a thing has a uniform motion, and it observes the excitation, then
    the excitation has the same properties as if it wasn't moving. That was
    the idea behind the Uncertainty Principle, and the reason the
    uncertainty of momentum and uncertainty of position were interconnected
    is that they were the phase shifts of the excitation. If an electron had
    a "period", it would mean that it would go back-and-forth, and that
    means the electron would have an excitation, not a phase shift, so an
    electron doesn't have a period, but a phase.

    It was 100% AI-generated nonsense.
